| Spec | Value |
|---|---|
| RTP | 94.50% on regular spins, 94.50% with the Ante Bet on, 94.50% on the Buy Free Spins. All three print on rules page 4 of 9. The combined figure including the jackpot renders as XXX%, because the operator sets the contributions and the game will not guess them |
| Volatility | High, producer meter 5 of 5 |
| Max win | 5,000× total bet with the ante off, 4,000× with the ante on, both worded “except Jackpot”. Those are the same 100,000 coins |
| Hit frequency | Not published for this build, and no community sample of any kind exists for it. The Gates of Olympus maths this build runs on tracks 1 win in 3.4 spins with a bonus every 209.4 across 1,421,870 logged spins, and that original runs 96.50% |
| Bet range | A$0.20 to A$240.00 with the ante off, A$0.25 to A$300.00 with the ante on. The printed A$300.00 maximum is only reachable with the ante active. A$0.20 is also the minimum jackpot-eligible bet |
| The engine | 6×5 pay-anywhere, minimum 8 matching symbols, unlimited tumbles, multiplier orbs valued 2× to 500× that add together and apply once at the end of a tumble sequence. Four or more Poseidon scatters open 15 free spins, 3 or more during the round adds 5 more, and the round’s total multiplier never resets. Buy Free Spins costs 100× total bet. The Ante Bet moves the stake to 25 coins, doubles the natural trigger rate and greys the buy out. Four local progressive tiers, GRAND, MEGA, MAJOR and MINOR, drop at random at the end of a base-game spin only |
The winning line
Roughly two thirds of the 94.50 return points are buried in free spins. The four local pots sit outside the 5,000× cap, mind you, but they can only land when a base game spin finishes. Keep it flat at 20 coins and A$0.20 so the pots stay fully live. Any round that gets past 100× total bet goes in the bank.
The pot costs exactly 2.00 points, and none of it comes off the ceiling
We pulled the RGS init payload for this build and for Gates of Olympus I pulled both builds off Pragmatic’s own demo host on the same day and ran the same method over them, then checked every field. Honestly, the paytable matched. So did all thirteen symbol rows, the 2× to 500× orb ladder and the scatter pays. Free spin counts matched too, along with coin values, the 100× buy price and the 5,000× cap. Even the 1 in 697,350 max win odds were identical. One number changed. Regular, ante and purchase RTP show 94.50% here against 96.50% there, verified against Pragmatic’s own demo of both builds.
So the ticket price is known to the point: 2.00 percentage points, and unlike its stablemate Tiki Hut Megaways Jackpot Play, which gave up some ceiling by cutting 12,305× to 9,000×, this build does something rougher. It leaves the tail alone and takes the full levy straight out of return. That is 2.00% of turnover in actual money: another A$4.00 expected loss per 1,000 spins at A$0.20. At A$2.00, it is A$40.00 per 1,000.
What you get for that levy is deliberately left unpriced. Look, rules page 5 of 9 shows four contribution lines, and every one says 0% in free play because there is no operator pool attached. Page 6 of 9 then closes with “The calculated RTP of the game, including Jackpot BONUS game is:XXX%”. These pools belong to one brand, not a network. They reseed after every hit from a slice chosen by the operator. Across all nine rules pages there is no must drop condition or drop by ceiling, while an operator can mark a tier “Jackpot closed” and keep the accrued amount. Our demo embed shows XXX across the whole bar. That means the pool is unattached. The game is not broken.
One more honest line, because nobody else will write it: there is no community data on this build at all. There is no Slot Tracker page or forum thread, and no verifiable clip either. Frankly, a proper jackpot dataset is never going to exist here because every pool is private to one casino. Any session behaviour number below comes from the original Gates of Olympus at 96.50%, and it is labelled that way every time.
Three modes, one RTP number
| Mode | Coins per spin | Bet range | Natural trigger, on the Gates maths | Share of spins with no jackpot draw | Buy panel | Cap as printed |
|---|---|---|---|---|---|---|
| Flat spin | 20 | A$0.20 to A$240.00 | about 1 in 448 | about 3.2% | live, 100× total bet | 5,000× |
| Ante Bet | 25 | A$0.25 to A$300.00 | about 1 in 224 | about 6.3% | greyed out | 4,000× |
| Buy Free Spins | 20 plus a 100× ticket | A$20.00 at the minimum, A$200.00 at the A$2.00 default | instant | 100% of the bought round | is the mode | 5,000× |
There is no RTP column because there is nothing useful to put in one. All three modes certify at 94.50%, straight from rules page 4 of 9. On the original, sure, that is trivia. Here it decides the whole argument. Return gives the punter no clue which button is better, leaving variance on one side and jackpot exposure on the other.
Read the cap column properly before panicking. Five thousand times 20 coins gives 100,000 coins. Four thousand times 25 coins gives the same 100,000 coins. The ante did not chop a fifth off the ceiling. It made the denominator 25% bigger, and the original works the same way.
Setting the mode before the first spin
Step 1 — Price the pool before paying the 2.00-point levy
The jackpot bar gives you four amounts but hides the feed rate behind them. Rules pages 5 and 6 of 9 are where that number lives. At a live operator, those pages show real contribution percentages, plus a real combined RTP instead of the demo’s zeros and XXX. Mind you, that screen is the only per casino disclosure anywhere in the product, and barely anyone opens it.
Action: Open the “i” panel and go straight to page 5 of 9, then page 6 of 9. Write down the four contribution figures plus the combined RTP line. Then do one subtraction. Well, 94.50% plus contributions has to beat 96.50% before this build is anything other than a worse Gates of Olympus. Until that subtraction gets over the line, every A$200 of turnover feeds A$4.00 into pools whose size you still do not know.
Watch for: Look for four tiers showing live amounts rather than XXX. Check whether any cell says “Jackpot closed”. Then read the clause that redirects an unpaid pool’s contributions into another tier. There is also a lag warning, which means the figure on the bar sits behind the real pool.
Decision branches: If page 6 of 9 shows a combined figure above 96.50%, the pools are covering the levy and Step 2 is live. If it comes in below 96.50%, still says XXX or has any tier marked closed, those 2.00 points are buying you nothing this session. The original sits at 96.50% at AU facing casinos that carry it, with the same paytable and the same orbs. Same cap too. Look, if the lobby loads the game without a jackpot bar above the reels, the operator has not integrated the jackpot module at all. Base spins are copping a levy for thin air. Walk. If you still want the pot chase without paying this price → Egg Rush Jackpot Play makes the same 2.00 point trade on a cluster engine without an ante getting in the way. Tiki Hut, mind you, runs 95.45%.
Step 2 — Lock the bet multiplier at 20 coins or 25, and price the dead time
Most guides for the original reckon the ante is the sharp play. Fair enough, but those guides were written for a version with no pots sitting on the bar. Here the ante hits three places at once. Stake jumps 25%, while the natural trigger rate roughly doubles from about 1 in 448 to about 1 in 224, based on BigWinBoard modelling of the original at 96.50%. The Buy Free Spins panel also gets switched off. Since jackpots only resolve at the end of a base game spin, that faster trigger rate roughly doubles the chunk of your session spent in spins where no pot can land.
Action: Run 20 coins when the pools are live and look healthy on the bar. Flip to 25 coins only if Step 1 came back closed or unattached, because then the free spins round is the only target left. At A$0.20, the flat lane burns A$0.20 a spin. The ante lane costs A$0.25 for the same board.
Watch for: Honestly, the tells are dead simple. The BET readout shifts from A$2.00 to A$2.50 on the default coin, and the buy panel greys out the instant you flip the toggle. Rules page 8 of 9 also reads 4000x again with the switch on.
Decision branches: If the pots are live and you are here for pot exposure, stay on 20 coins at about 3.2% dead time. That also keeps the buy sitting there as a Step 4 option. If the pots are closed, tiny or XXX, run the ante instead. You wear about 6.3% dead time, but it costs you nothing you were actually using and you get the 1 in 224 trigger. If the bankroll is under A$50, stick to 20 coins at A$0.20 flat. A 25% stake rise on a wallet that thin strips out about 160 spins while cutting pot exposure at the same time. And if a deposit bonus is active with a max bet near A$5 to A$7, flat spins are the only legal lane anyway. Conveniently, that is also the mode with full jackpot exposure.
Working the round you paid for
Step 3 — Grind the base game, because it is the entire jackpot window
Base game tumbles carry only about 28 to 33 of the 94.50 return points, so this grind is not where the pokie does its paying. The pots are. More importantly, the base game is the only place they can pay. Every base spin finishes with a draw assessed on it. Every free spin gets none, whether it came naturally or through a buy.
Action: Spin A$0.20 flat with A$100 behind you and you have 500 spins funded. The jackpot wording says the odds are “directly related to the bet amount”, and A$0.20 is already eligible, so this is proportional scaling rather than a tier gate. Push the stake to A$2.00 and you multiply pot exposure by ten. You also multiply expected slot side loss by exactly the same ten. Frankly, the value per dollar staked has not improved by a cent. You have only sped up the burn.
Watch for: Watch the scatter counts. 4 Poseidons pay 3× bet and open the round, while 5 pay 5×. Land 6 and that pays 100× on its own. Keep an eye on the 12 plus symbol tier as well, where Trident pays 50× against 10× at the 8 to 9 tier. That 8 to 9 band, mind you, is a rebate. It is not income.
Decision branches: If the stash is A$100 or better at A$0.20, grind the full 500 spins. On the original’s maths, about 500 spins at a 1 in 448 natural trigger comes out near 67% odds of seeing at least one organic round, and every one of those 500 spins carries a pot draw. If 900 spins go by without a round, well, that is still a 13% outcome at 1 in 448, roughly one session in eight of that length. The machine has not suddenly gone cold. Keep the stake where it is or end the session. If you feel like raising after a dry patch, remember the trigger probability per spin has not shifted by a thousandth. At 94.50%, every raised spin is also burning 2.00 points more than the identical spin on the original.
Step 4 — Buy the 15 spins only once you have written the pots off, then price the orb exit
The buy is the one call on this pokie where the jackpot cost is crystal clear. A 100× ticket at the A$2.00 default costs A$200, and what you get is 15 spins with all four tiers switched off for you. Certified RTP is still 94.50%, exactly the same as the base rate. So, zero EV gained and 100% of your pot exposure handed back, while the bar keeps glowing and carrying on like nothing changed. Tiki Hut at least paid 0.08 of a point for making that trade. This one pays nothing.
Action: Price the buy at the floor, not whatever default stake is sitting there: A$20.00 at A$0.20 a spin. Five tickets is the hard ceiling, so A$100 of stash covers the lot. Each ticket then has one job, clear 100× total bet or it has not paid for itself. Inside the round, keep the stake flat. Let the total multiplier do the heavy lifting, because an orb only joins that running total when the spin actually wins.
Watch for: Look, the running total multiplier never resets during the round. Then there are the retriggers: 3 or more scatters landing during play add 5 extra spins. Orbs are the trap for the eye. They can show anything from the 2× to 500× ladder on a losing spin, look bloody useful, and bank nothing.
Decision branches: If the pots are live on the bar, skip the buy. Full stop. It is the only move in the game that deliberately kills pot exposure for a stretch of spins. If the pots are closed or unattached and the round itself is the whole plan, buy at A$0.20 and cap it at five tickets. Stop at five regardless of the result. If a bought round or a natural round clears 100× total bet, close it out. About 65% of 100× buys on the original return less than they cost, while the average round there pays 45.6×. Beat the ticket price and you have already outrun two thirds of the distribution. If the total multiplier gets to 50× or better with spins left, hold the stake and let the counter finish. One late 12 symbol cluster under an accumulated 50× can be worth many average rounds. If the round total touches 5,000× total bet, that is it. The round ends itself, remaining spins are forfeited, while the pot draw sits outside that cap in either direction.
The maths under the 2.00-point levy
Start with the split. On the original’s maths, the free spins round carries roughly 65 to 70% of total return. Recomputed against this build’s 94.50%, that puts about 61 to 66 return points inside the round, with roughly 28 to 33 left in base tumbles. That is DERIVED, mind you, and it needs the hedge: Pragmatic does not publish where the 2.00 point cut lands. We only know the cut happened.
Variance next. The original and this build share every parameter that actually drives σ. The paytable and reel strips are the same, as are the orb ladder and scatter array. The 5,000× cap also matches, along with the 1 in 697,350 cap odds. That makes transferring the original’s σ far better supported than using some ordinary lookalike proxy. A 2.00 point RTP shift only enters the variance expression through the RTP² term, worth about 0.04. Working figure:σ about 10 to 14 per A$1 staked at round level, DERIVED. Honestly, at σ = 12 and A$0.20 a spin, a 200 spin session sits inside roughly ±A$66 around an expected loss of A$2.20. Push that to A$2.00 a spin and the same band blows out to ±A$665 around an expected loss of A$22. Minimum viable stash: A$50 to A$100 at A$0.20. At A$1.00, call it A$300 to A$500.
The dead time arithmetic behind Step 2 matters because nobody else on this page has published the number. Ante off, the round adds 15 spins per roughly 448 base spins, so pot free spins are 15/(448+15), about 3.2% of all spins. Ante on, it becomes 15/(224+15), about 6.3%. Retriggers nudge both rows higher, but the ratio is the point: the ante roughly doubles pot dead time. It also lifts stake 25%, so pot odds per eligible spin rise proportionally. Those effects work against each other. Pragmatic gives us nothing that lets anyone net them out properly, so, to be fair, the useful bit here is the mechanism rather than some fake verdict.
Buy economics are pretty simple because the RTP stays flat. Community distribution on the original is ESTIMATED with no PAR confirmation: about 20% of rounds land under 10×, while roughly 45% sit from 10× to 100×. Another 30% fall from 100× to 1,000×. About 5% make 1,000× and up. Average round is 45.6× against a ticket price of 100×, which is why roughly 65% of buys come back short. The game’s own win limit data puts the 5,000× cap at 1 in 697,350 spins, matching the figure AskGamblers publishes for the original. In a 1.4 million spin sample of the original, the best win reached 2,475×. Half the ceiling, after 1.4 million spins.
One line on the house cut, then move on. At 94.50%, the slot side returns 94.5 cents in the dollar before any pot contribution gets added on top.
Where this build trips punters
- Buying free spins while the bar is lit. Page 5 of 9 says jackpots “cannot be won during any feature”. A A$200 ticket at the A$2.00 default switches off all four tiers for 15 spins or more, for no RTP gain at all, while the meters keep animating overhead.
- Flipping the ante on because it is the smart play on the original. It disables the buy outright and roughly doubles pot-dead time, from about 3.2% of spins to about 6.3%. Every guide written for Gates of Olympus is blind to this, because that game has no pots to go dead on.
- Reading 4000x on page 8 of 9 as a nerf. It only appears with the ante on and it is the same 100,000 coins as 5,000× at 20 coins. Punters have talked themselves out of the ante over a denominator.
- Treating “higher bets have a higher chance” as a threshold to clear. It is proportional, and A$0.20 is already eligible. There is no stake level that improves pot value per dollar wagered, so bet-up buys exposure and expected loss in the same breath.
- Never opening pages 5 and 6 of 9. Two casinos running the identical 94.50% build can differ by whole points of total return depending on which contribution setup the operator bought, and that screen is the only place it is written down anywhere in the product.
- Playing this one when the original is on the same shelf. Byte-identical maths, 2.00 points better, and the original is the version Australians actually reach. If the tail matters more than the pots, Gates of Olympus 1000 triples the ceiling to 15,000×, and Gates of Olympus Super Scatter reworks the trigger instead of bolting a lottery on.
- Judging the pools off our demo. The embed shows XXX on all four tiers and 0% contributions because no operator pool is attached to free play. Small pots and a fake jackpot are two different readings and both are wrong.
Stop numbers for pools you cannot see
Pot-status exit: Any tier reading “Jackpot closed” is enough to bin it. Same goes for page 6 of 9 still printing XXX at a real money operator. Either way, frankly, you are paying the 2.00 point levy for nothing. Close it.
Contribution-read gate: No spin before pages 5 and 6 of 9 have been read and written down. Well, if the combined figure does not clear 96.50%, the original is the play.
Base-turnover budget: A$100 bankroll, A$0.20 a spin. That buys 500 spins with no top ups. Once that cash is cooked, the session is done, no matter what the pot bar reckons.
Dry-stretch line: Look, 900 base spins without a natural round is still a 13% outcome at 1 in 448. That is the stop point. Same stake, session over, no silly bump in bet size trying to force it.
Buy-series cap: Five tickets max. Each costs A$20.00 at A$0.20, which puts the full spend at A$100. Honestly, five dud rounds are just five dud rounds. They are not permission to buy number six.
Round exit: Any round finishing above 100× total bet gets banked, full stop. If the accumulated multiplier has already reached 50× or better, play whatever spins remain on the counter before making the call.
Bonus-funds unknown: To be fair, none of the operator terms reviewed spell out whether a pot hit using bonus money pays in full. They also do not say if bonus funded spins qualify for the pool at all. Get the casino to confirm it in writing before burning bonus funds chasing tiers.

- Multiplier symbols: four coloured gems set in gold seahorse frames, present on all reels, hitting at random on spins and tumbles in both the base game and free spins. Value on landing is random from 2×, 3×, 4×, 5×, 6×, 8×, 10×, 12×, 15×, 20×, 25×, 50×, 100×, 250× and 500×.
- Wild: none.
- All wins are multiplied by base bet, and when several symbol types pay on the same board every win is added into the total.
- The ladder is identical to Gates of Olympus, row for row. Only the art was swapped: Zeus became Poseidon, the hourglass became a crown, the chalice became an amphora.
Game rules
Base game
The jackpot bar above the reels gets its money from the base game. That matters, because this is the only part of the pokie where those four pots can actually drop. Honestly, the cost is obvious in the maths: 94.50% here versus 96.50% on the identical engine without the jackpot layer, a full 2.00 percentage points gone.
- 8 or more matching symbols anywhere on the 6×5 grid form a win. Position is irrelevant and there are no lines to cover.
- TUMBLE: winning symbols disappear, the remaining symbols fall to the bottom, and empty positions are refilled from above. Tumbling continues until no new win forms, with no limit on the number of tumbles.
- Every win from one spin is added to the balance only after all tumbles from that spin have been played.
- Multiplier symbols hit at random on any reel during spins and tumbles. When the chain ends, the values of all multiplier symbols on screen are added together and the total win of the sequence is multiplied once by that figure.
- Nothing carries between base spins. A multiplier belongs to the tumble chain it landed in and leaves with it.
- A jackpot can be awarded at random at the end of any base game spin, at any bet of A$0.20 or more.
Jackpot Bonus Game
This is why the build exists, and it is also why the RTP cops the two point hit. Four progressive tiers sit live above the reels. Mind you, they are not one industry wide network pool. Each casino creates and hosts its own setup, then funds and configures it locally, so the same pokie can show completely different amounts from one site to another.
- Up to four progressive jackpots run at once: GRAND (A), MEGA (K), MAJOR (Q) and MINOR (J). The operator can run fewer.
- Jackpots are won at random at the end of any spin in the base game. They cannot be won during any feature.
- The winning tier is revealed in a pick screen. Items are opened until three with the same name appear.
- Minimum bet to qualify is A$0.20. The chance of winning any available tier is directly related to the bet amount, so a higher bet carries a higher chance, and there is no tier locked behind a minimum above that A$0.20.
- Pools grow from contributions taken out of all participating player bets, at four rates the operator sets rather than the producer.
- A tier that is won is reseeded from an amount set aside for that purpose out of the same contributions, and starts rebuilding from that seed.
- There is no must-drop and no drop-by ceiling anywhere in the nine rules pages. There is a jackpot limit: once a tier reaches it, further contributions are diverted to the next jackpot.
- A tier can be temporarily shut down and marked “Jackpot closed”, keeping the amount accumulated before the shutdown. On closure of an unpaid jackpot, player contributions are transferred to another jackpot.
- Simultaneous winners are not split. Wins are awarded in order and each collects the value accumulated at the exact moment of their win.
- Displayed pot values can differ from actual values because of internet lag.
- Jackpot wins sit outside the max-win cap. The rules state the limit applies “except Jackpot”.
Free spins
Four scatters get the round going. From there, forget everything except the running total multiplier. It keeps climbing for the whole feature and never resets, which is how the game can actually get anywhere near that 5,000× ceiling.
- 4 or more SCATTER symbols anywhere on the screen award the round, which starts with 15 free spins.
- 3 or more SCATTER symbols during the round award 5 additional free spins. Retriggers are unlimited in the rules text.
- Whenever a multiplier symbol hits and that spin results in a win, its value is added to the total multiplier for the rest of the round.
- The total multiplier then applies to every later winning spin in the round, and it never resets until the round ends.
- The condition is worth reading twice: a multiplier only banks into the total if the spin it landed on wins.
- Special reel strips are in play during the round.
- No jackpot can drop on a free spin, whether the round was triggered naturally or bought.
Ante Bet
The ante is the usual trade on this engine, but the jackpot version makes you pay for it twice. Sure, the stake goes up by a quarter and the wait for a natural trigger is roughly halved. The catch is the bonus buy gets switched off, while more of the session shifts into feature spins where the jackpot cannot drop.
- Bet multiplier 25× instead of 20×, which is 25% more per spin. At the demo default the bet moves from A$2 to A$2.50.
- The chance of triggering free spins naturally is doubled, and more SCATTER symbols are present on the reels.
- BUY FREE SPINS is disabled while the ante is active. The panel greys out on screen.
- RTP with the ante on is 94.50%, identical to a regular spin. The ante buys a faster trigger, not a better return.
- The A$300 printed maximum bet is only reachable with the ante on. Ante off, the ceiling is A$240.
- The max-win line on rules page 8 of 9 reads 4,000× while the ante is on instead of 5,000×.
Buy Free Spins
The buy charges a fixed price based on the current total bet and throws you straight into the round. Simple enough. On this build, though, it is also the only spend that gives you zero jackpot exposure from start to finish.
- 100× current total bet, which is A$200 at the A$2 default and A$20 at the A$0.20 minimum.
- Buy RTP is 94.50%, identical to a regular spin, so the buy shifts variance rather than expected value.
- The purchased round is the same 15 free spins with the same accumulating total multiplier.
- The buy is unavailable while the Ante Bet is on.
- All four jackpot tiers are switched off for every spin of the round, while the jackpot bar stays lit and animated above the reels.
Max-win cap
The ceiling is a hard stop, not some rounding quirk. Look, the figure shown on screen can change when a switch is flipped, but the actual ceiling does not move at all.
- 5,000× total bet, with jackpot wins explicitly excluded.
- If the total win of a round reaches the cap, the round immediately ends, the win is awarded up to the cap, and all remaining features are forfeited.
- With the Ante Bet on, the same screen reads 4,000× total bet. Both figures are 100,000 coins: 5,000 × 20 coins and 4,000 × 25 coins. The multiplier falls because the denominator grew by 25%, not because the ceiling was cut.
- The cap is unchanged from Gates of Olympus, which carries the identical 5,000× and 4,000× pair.
- Odds of reaching the cap are 1 in 697,350 spins, the same figure the original carries.
- A win above 5,000× total bet is only possible through a jackpot drop.
RTP versions
Two versions of the same maths are sitting on the producer’s own demo host. The difference between them is basically the bill for that jackpot bar, and you can see it right down to the second decimal.
| Build | Regular spins | Ante Bet | Bought feature | Max win | Jackpot bar |
|---|---|---|---|---|---|
| Kingdom of Atlantis Jackpot Play | 94.50% | 94.50% | 94.50% | 5,000×, jackpots excluded | Four local tiers |
| Gates of Olympus, the original | 96.50% | 96.50% | 96.50% | 5,000×, no jackpot to exclude | None |
- Both rows were read on the same day, from the same producer demo host, by the same method. The delta is exactly 2.00 percentage points in every one of the three modes.
- The cut is entirely in the RTP. The cap, the cap odds, the paytable, the multiplier ladder, the scatter pays, the free-spin counts, the bet levels and the buy price are all unchanged from the original.
- 94.50% is also the bottom rung of the original engine’s own RTP ladder of 96.50%, 95.50% and 94.50%. Whether any operator runs a 95.50% or 96.50% configuration of this Jackpot Play build is unverified. No named casino was found running it at anything but 94.50%.
- The jackpot money is added on top of 94.50%, not carved out of it. Rules page 5 of 9 prints the four contribution percentages the operator has chosen, and page 6 of 9 prints the combined figure as “The calculated RTP of the game, including Jackpot BONUS game is:XXX%”.
- Those two pages are the only per-casino disclosure that exists anywhere in the product. Two casinos both running the 94.50% build can return materially different totals depending on which jackpot setup they bought, and the producer publishes no default contribution table.
- 2.00 percentage points is A$4 of extra expected loss per 1,000 spins at A$0.20, or A$40 per 1,000 spins at A$2. That is the admission price to a pool whose size nobody outside the casino can quote.
Ante Bet and jackpot dead time
Every guide for the original treats the ante as the clever switch to flick. On this jackpot build, though, there is another consequence the original simply cannot have because jackpots only fall in the base game. To be fair, the arithmetic is easy enough to check for yourself.
- Jackpots drop only at the end of a base game spin, so free spins are dead time as far as all four tiers are concerned.
- Ante off, the natural trigger runs about 1 in 448 spins on this engine, and 15 free spins per trigger works out at roughly 3.2% of all spins spent inside the feature.
- Ante on, the trigger roughly halves to about 1 in 224, so the feature share roughly doubles to about 6.3% of all spins. Retriggers push both figures a little higher.
- The ante also raises the stake 25%, and jackpot chance is proportional to bet size, so exposure per eligible spin rises at the same time.
- The two effects pull in opposite directions and no published contribution or drop-probability figure exists to net them out. The mechanism is documented; the balance is not.
- The trigger frequencies above come from modelling of Gates of Olympus, the identical maths, not from measured play on this build.
Volatility distribution
The producer stamps it with 5 of 5 bolts. The figures underneath are carried over from the original, frankly, because the payload diff shows nothing else in the maths that separates the two.
- The in-game definition is plain: high volatility games pay out less often on average but the chance to hit big wins in a short time span is higher.
- No standard deviation, hit rate or bonus frequency has ever been published for this build. Community tracking of the original, across about 1.42 million spins, gives a hit rate near 29.8%, roughly 1 in 3.4 spins, and a bonus frequency near 1 in 209 spins.
- That same sample tracked 84.3% against certified tiers of 96.50%, 95.50% and 94.50%. On a game whose cap sits at 1 in 697,350, 1.4 million spins has not gathered enough right tail to converge, so treat it as signal about spin behaviour, not as a return figure, and note it belongs to a mix of tiers rather than to this build.
- Average bonus payout in that community sample was 45.6× stake, against a buy price of 100× total bet, and the best result across the whole sample reached 2,475×, under half the cap. The modelled 1 in 448 natural trigger is the conservative figure to plan a bankroll against, rather than the tracked 1 in 209.
- At 1 in 448, a 900-spin dry stretch with no trigger carries roughly a 13% chance, so about one session in eight of that length.
- The jackpot adds a second variance source that sits in none of those figures: a bet-proportional random drop of casino-specific size, bounded only by the operator’s pool and explicitly exempt from the 5,000× cap.
Why published figures disagree
Almost every online listing manages to muddle together the jackpot re skin, the original game and a bet multiplier. Well, compare a few of those pages and the problem jumps out straight away: the figures simply cannot all be true.
- RTP is quoted as 95.5% on most aggregator pages and 96.41% on one. The producer’s own build serves 94.50% in the player-facing help screen and in the game server payload, across three separate sessions. One aggregator’s page title does carry 94.5%.
- “20 paylines” appears everywhere and is wrong. There are no paylines at all. 20 is the bet multiplier, the coins staked per spin, and it becomes 25 with the Ante Bet on.
- Several pages give the maximum bet as a 100 unit ceiling. The rules screen prints A$0.20 minimum and A$300 maximum, with A$300 reachable only while the ante is on.
- Some pages quote 4,000× as the max win with no caveat. That is the ante-active screen, and it is the same 100,000 coins as 5,000× with the ante off.
- No producer game page exists for this title. Both plausible URLs return 404 and a sweep of all thirteen producer games sitemap files returns zero entries for it, which is why this page is built on the game’s own nine rules pages and its server payload.
- Aggregator pages titled simply “Kingdom of Atlantis” are the same product. The game code behind them is vsprg20kingatl, whose registered name is Kingdom of Atlantis Jackpot Play. There is no non-jackpot version of this title, and no separate base build to compare against other than the original it re-skins.
Demo notes
The free demo runs the lot. Mind you, there is one display quirk that can make a working feature look busted unless you know about it first.
- All four jackpot meters render as “XXX” and the four contribution rates print as 0%. No operator pool is attached to a demo, so there is nothing to feed the pots and nothing to display.
- The combined RTP line on rules page 6 of 9 shows “XXX%” for the same reason. Unresolved, not zero.
- The slot side behaves exactly as the real-money build: same 94.50% maths, same 5,000× cap, same 100× buy panel, same nine rules pages, same ante toggle.
- The demo loads on a generic jurisdiction setting with both the buy feature and the ante enabled, and renders AUD throughout at CREDIT A$100,000 and BET A$2 by default.
Game series
This build is basically a reskin of one of the most flogged engines on the market. It also sits in a small jackpot range the producer keeps separate from its main catalogue.
| Title | Relationship to this build |
|---|---|
| Gates of Olympus | The original maths, named as the source in the producer’s own partner bulletin. Identical paytable, reel strips, multiplier ladder, scatter pays, buy price, cap and cap odds, at 96.50% instead of 94.50% |
| Gates of Olympus 1000 | Same lineage at 96.50%, with the ceiling raised to 15,000× and a heavier right tail instead of a jackpot bar |
| Gates of Olympus Super Scatter | The other Olympus variant on this site. A scatter-driven rework of the feature rather than a jackpot layer |
| Egg Rush Jackpot Play | Same jackpot programme, same 94.50%, same four tiers, same 2.00-point cut against its own original. A 7×7 cluster engine, and no Ante Bet, so no ante and buy conflict |
| Tiki Hut Megaways Jackpot Play | Same programme on a Megaways engine at 95.45%, but it pays for the pots with a cap cut from 12,305× to 9,000×, which this title does not suffer |
| Queen of Atlantis | Shares the Atlantis setting and nothing else. A different engine, no jackpot bar |
- The producer used to run Jackpot Play as an overlay on flagship titles. The overlay generation, headed by “Gates of Olympus Jackpot Play”, was removed on 31 January and replaced by standalone re-skins so the flagship RTP tables stay untouched.
- The vsprg prefix on the game code is the marker for the whole Jackpot Play product line.
- The in-game logo art reads only KINGDOM OF ATLANTIS. The Jackpot Play suffix lives in the lobby name and on a corner badge on the key art, which is why aggregators drop it.
AU availability
Pragmatic Play The producer holds no Australian licence. On this title, though, the AU-facing setup has one wrinkle worth checking before any deposit goes in.
- No AU-facing casino was confirmed carrying Kingdom of Atlantis Jackpot Play. Every operator found listing it is European, Ontario-regulated, Romanian or a United States sweepstakes site, which tracks with the build needing the operator to have integrated the producer’s jackpot system.
- The original Gates of Olympus is confirmed at AU-facing Stake, BC.Game and Rainbet, at 96.50%. The version an Australian can actually reach is the one two full points better.
- Under the Interactive Gambling Act 2001 online pokies are not licensed onshore, so AU access to this producer’s content runs through offshore licensed casinos. The offence sits with the operator, not the player.
- AUD is supported at engine level. The producer’s own demo renders A$ throughout, from A$0.20 to A$300.
- Pools are local to a single brand, so pot size tracks that one casino’s traffic. A quiet site funds a thin pool at exactly the same 94.50% cost, and the rules allow any tier to be closed while keeping what it has accumulated.
- Offshore bonus terms commonly cap the stake per round in the A$5 to A$10 band, which makes a 100× buy impossible while bonus money is live and leaves flat base-game spins as the only mode available. That is also the only mode with full jackpot exposure.
- Whether a jackpot won on bonus funds is paid in full, and whether bonus-funded spins qualify for the local pool at all, is not addressed in any operator terms reviewed. The game’s own rule is only the A$0.20 minimum.
FAQ
Q: Why is the RTP 94.50% and not 96.50%? A: Because the jackpot layer comes straight out of the cut. The same engine returns 96.50% without the jackpot bar. Here, 2.00 percentage points of every wager feed four operator-run pools.
Q: Is this the same game as Gates of Olympus? A: Straight up, yes on the maths. The paytable and reel strips match, as do the multiplier ladder and scatter pays. Buy price, cap and cap odds are the same too. Only the RTP and the art changed.
Q: Can a jackpot drop during free spins? A: Short answer: no. Honestly, the draw only fires after a base game spin, so every free spin is dead jackpot time for the punter, whether it was triggered or bought.
Q: Is the max win 5,000× or 4,000×? A: Both, depending on the switch. Ante off shows 5,000×. Ante on shows 4,000×. Both still equal 100,000 coins, so the ceiling never shifted, only the denominator did.
Q: Does the Ante Bet improve the return? A: Not really. Ante RTP stays at 94.50%, exactly the same as a regular spin. You pay 25% more and roughly halve the wait to a trigger. It also disables the bonus buy, while doubling the time spent in spins where jackpots cannot drop.
Q: How big are the four jackpots? A: Well, there is no public data for this title or any Jackpot Play game. Each casino runs its own local pools, with those pools seeded and reseeded by its own players. That means no figure carries across from one site to another.
Q: Why are the jackpot meters showing XXX in the demo? A: Because a free demo has no operator pool hanging off it. The meters have nothing to read, so the contribution rates show 0%. Have a crack at the slot side though, the maths are live.
Q: Can Australians play Kingdom of Atlantis Jackpot Play? A: No AU-facing casino was confirmed carrying it. The producer holds no Australian licence. So, under the Interactive Gambling Act 2001, every route in runs through offshore operators.
