Specs

Giza’s Portals is a Tom Horn Gaming release that landed on 19 May 2026, so it was genuinely new at the time of writing. Mind you, that explains a couple of the gaps flagged below. It is a straight up 5×4 Egyptian pokie with 25 lines. No cascades. No ways pays. The whole thing hangs on one idea: a Golden Pyramid wild carrying a random multiplier of ×2 to ×5. Get more than one on the same line and it can turn nasty fast. Every figure in the table above comes from Tom Horn’s Game Specifications table, the live producer demo or a cross confirming aggregator listing. Anything we could not source is marked unverified. We have not plugged the holes with guesses.

Two numbers need a flag straight away. Honestly, they tell you how to approach this pokie before you even load a spin.

First, the RTP. Giza’s Portals returns 95.01%, and that should affect how you size the session because it sits below the roughly 96% offered by a typical modern pokie. Tom Horn’s own spec table shows 95.01%. SlotCatalog and clashofslots back it up, as do iGamingToday and bf1.io, so the figure is not up for debate. In practical terms, the house edge is 4.99%, around one and a half times the edge on a 96.5% game. You may not feel that from one spin to the next. Over a long session, though, it adds up, and your bankroll gets chewed faster than it would on a 96 plus pokie at the same stakes. We are not dressing that up. It is the most useful fact on this page.

The second number is the ceiling, and the story is cleaner here. The top win is 3,898× your stake. Unlike plenty of new releases where the aggregator crawls spit out different answers, this one is solid. Tom Horn prints “Max Exposure x3,898” on the producer page. SlotCatalog and clashofslots quote the same 3,898×, with iGamingToday and bf1.io doing likewise. That gives you five sources in agreement and no conflicting number doing the rounds. Take 3,898× as the firm ceiling and size the bankroll around it. It is a moderate top end by current standards, not some five figure multiplier beast. To be fair, that suits a medium volatility line slot. The route there is stacking multiplier wilds on one line, which we cover below.

Symbols & Paytable

Tom Horn has not published a detailed multiplier table for each symbol in this title. Well, that means the right hand column has to stay qualitative because the payout figures are not sourced. The symbol roster itself is confirmed through the producer Features copy and the live demo board.

A few things need clearing up in that table. The Golden Pyramid runs the show. It is the wild and substitutes for every symbol except the scatter. Whenever it joins a winning line, it slaps a random ×2, ×3, ×4 or ×5 onto that line win. That mechanic does most of the work on the road to the 3,898× ceiling. It is also easy to read wrong, so we break it down below. The scatter appears as a “Bonus” tile on the live board and pays no standard line win. Its only purpose is triggering the Tomb Pick Up Bonus when 3, 4 or 5 land. The Egyptian deity symbols sit above the card ranks. You have the Pharaoh mask and Anubis, plus the queen figure and scarab, while A, K, Q, J make up the lower end. The exact multiplier for a five of a kind is not listed on any public page. No PAR sheet or paytable has surfaced for this release either. So we left the figures out. The structure is confirmed, but the exact symbol payouts are still unsourced. Any site publishing them should be treated as unverified.

Game rules

Base game

Wins are checked from left to right across 25 fixed lines on a 5×4 grid. There is no tumble or cascade. You will not find an expanding symbol trick either. Each spin gets one evaluation, which leaves the multiplier wild as the only proper variance lever in the base game.

• 5×4 grid with 25 fixed paylines. Wins are evaluated from left to right.
• Each spin resolves once. No cascade. No re drop mechanic follows a paid spin.
• There is no published gamble feature or double up option. The producer copy lists neither, so honestly, do not assume one exists.
• The Golden Pyramid wild powers the base game. Of course, it gets a full section below.

Golden Pyramid multiplier wild

This mechanic defines the slot, so take a slower look at it. The stacking rule is where punters tend to get it wrong. When a Golden Pyramid wild lands as part of a winning line, it carries a random multiplier of ×2, ×3, ×4 or ×5. That multiplier applies to the win on that line. The real catch is what happens when several wilds land on the same line. That, sure, is why the 3,898× ceiling exists in the first place.

• A Golden Pyramid wild joining a winning line stamps a random ×2 / ×3 / ×4 / ×5 onto that line’s payout.
• When two or more wilds land on the same winning line, their multipliers multiply by each other instead of adding together. A ×5 and a ×4 on one line is ×20 on that line, not ×9.
• The multiply-together rule is the whole engine behind the top-end win. The 3,898× ceiling is a stacked-multiplier-wild-on-one-line story, rather than a single big symbol hit.
• Because the wilds also pay in the base game, a meaningful share of this pokie’s return is recoverable without ever reaching the bonus, which matters for how you read the maths overall.

That multiplication detail is the single most-missed rule on slots built this way. A player who reads two ×5 wilds as a ×10 line is under-rating the spins that actually carry the slot, because two ×5 wilds is ×25. It also tells you where the danger and the value both live: in how many wilds you can get onto one line at once, rather than in the high-pay symbols themselves.

Tomb Pick-Up Bonus

The scatter feature here is a pick game rather than a straight free-spins drop, and it has two jobs: it hands out instant cash and it sets your free-spins count for the round that follows. The trigger and the structure are confirmed off the live demo intro.

• Triggered by 3, 4 or 5 scatter symbols.
• Opens 12, 16 or 20 sarcophagus boxes respectively, with 3, 4 or 5 player picks respectively.
• Boxes reveal instant cash prizes and/or free spins, which are summed into a cash-win total and a free-spins count.
• The free-spins award is variable. It is summed from what your sarcophagi reveal, not fixed to the scatter count, so there is no clean “3 scatters equals X spins” table to quote.

The thing to understand about this feature is that the number of scatters does not directly buy you a set number of spins. More scatters means more boxes and more picks, which raises the expected free-spins haul, but the actual count depends on what you uncover. That is why we have not printed a fixed spins-per-scatter table: it would be inventing precision the game does not give you.

Free Spins

The free-spins round is where the multiplier wild compounds, because the wilds turn sticky for the whole feature. This is the slot’s headline value, and it is capped, which changes how you read a bonus in progress.

• The Tomb Pick-Up Bonus sets the free-spins count, with up to 15 spins on offer.
• Wild symbols are sticky during the round. Once they land, they stay locked on the reels for the rest of the feature.
• Each sticky wild carries a random ×2 / ×3 / ×4 / ×5 multiplier and applies it to line wins. When more than one lands on the same line, honestly, the multipliers are multiplied together.
• The Free Spins cannot retrigger. The producer copy says so plainly, meaning the round cannot grow beyond the count banked from the pick game.

That non-retriggerable cap matters. Plenty of modern slots let the free-spins round re-arm itself over and over, and sure, that uncertainty is part of the appeal. Not here. You will never get more than 15 spins. The value of the bonus comes down to how many sticky multiplier wilds build up across them. Bank two or three sticky wilds early and the round looks very different from one that stays dry. With no retrigger in play, you can judge the feature ceiling once you know the spin count. Then it comes down to what sticks.

Bonus buy

This pokie has two buy tiers, both confirmed through the producer Features copy and the live demo UI. Choosing between them is the main buy-feature call.

• Buy Bonus costs 30× the current bet.
• Super Buy Bonus costs 100× the current bet.
• Each tier guarantees the relevant bonus on the next round. Mind you, the producer copy does not spell out exactly which bonus or feature tier each buy delivers, so the precise entry remains unverified.
• The buy-mode RTP is not published, so honestly, we are not quoting a buy-EV figure.
• Buy features are disabled in the UK under Gambling Commission rules and can be switched off by operators elsewhere. At AU-facing offshore casinos, the buy is generally available. Plenty of those casinos will void deposit-bonus play if you use it, though, so check the terms before buying.

This comes back to the RTP. On a 95.01% base game, neither buy is a value play against the house. Both carry the same below-average return as the rest of the slot. The Super Buy, in particular, asks you to spend 100× chasing a feature with an absolute ceiling of 3,898×. That is only about 39 times the cost of the super buy itself. It is a high-variance punt, not a path to better return. If you are buying at all on a sub-96 game, the cheaper 30× tier keeps the spend lower and trims the variance. The 100× super buy is best treated as paying extra for a faster ride. A swingier one too, of course, not better value.

Max-win cap

The top win on this pokie is 3,898× your stake, and the path to it is narrow and specific.

• Maximum win: 3,898× stake.
• The route to the cap runs through stacking Golden Pyramid wilds on a single line, where their multipliers multiply together, most realistically inside the sticky-wild Free Spins.
• Whether the round terminates on hitting the cap or simply stops accruing is not published, so treat the cap behaviour as unverified.
• The 3,898× figure is firm: producer plus four independent aggregators agree, with no conflicting number in circulation for this title.

Screenshots

The three shots below are pulled from the demo, also embedded on this page, so you can run the reels and both features yourself in fun mode. They show the base game, the Tomb Pick-Up Bonus and the free-spins round in turn. The on-screen text sits in the demo platform’s own fun-mode currency rather than AUD, and that currency may differ from what your operator serves, so read these for the mechanics rather than the money. In real play your casino serves AUD.

RTP versions

Only one RTP tier is currently sourced for this title, but Tom Horn is a studio that lets operators tune the figure on some of its games, so the AU offshore setup is worth a section of its own here, and it matters more than usual because 95.01% is already below average.

This part matters. The 95.01% you see quoted everywhere is the only tier that turned up on the producer spec table and across every aggregator, and no reduced 94.x or 92.x floor surfaced in the wild for this specific game. That is the sourced position. But Tom Horn does ship operator-tunable RTP on some of its titles, with a provider floor as low as 94% and configurable builds on games such as Fluxberry, which means an AU-facing offshore casino could in principle be running a reduced version of Giza’s Portals even though none turned up. There is nothing on the reels to tell you which build you are spinning. The only place the truth is written down is the casino’s in-game info panel, so open it and confirm the 95.01% figure before you commit a bankroll. On a game that is already sub-average, the difference between 95.01% and a 94% floor is the difference between a weak return and a weaker one, so mark the per-casino floors as unverified and check every time.

Provider context

Tom Horn Gaming is a Malta-headquartered RNG studio with offices across Malta, Slovakia and the Czech Republic, and for an Australian punter the legal context is the same as it is for every offshore RNG studio.

• Tom Horn holds UKGC, ONJN Romania and MGA licences, but it is not licensed under the Australian Interactive Gambling Act 2001, because no offshore RNG slot studio is. AU players reach its titles only through offshore-licensed casinos, typically MGA or Curacao.
• Accessing an offshore casino is not itself a criminal offence for the player under the IGA 2001. What the Act bars is operating or advertising real-money online slots to Australians locally.
• Tom Horn distributes through aggregator feeds common at AU-facing crypto casinos, but no specific operator was confirmed running this exact title at the time of writing, given it is roughly six weeks old. Mark the named-casino availability as unverified.

Game series

Giza’s Portals sits inside a cluster of Egyptian pokies an AU punter is likely to weigh it against, both inside Tom Horn’s own catalogue and across the wider market. The closest same-studio sibling is Book of Ba, and the recognisable cross-market benchmarks already have pages here too.

The comparisons are straightforward. If you want the same Egyptian pace with a higher top end while staying in the same variance band, Eye of Horus is the closest upgrade. If you want a bigger ceiling and do not mind more swing, Book of Dead is the famous benchmark at 5,000×. And Book of Ba is the higher-variance, same-studio sibling that swaps the multiplier wild for a Shatter Mode cascade and an expanding symbol.

Mechanic breakdown

One payout engine drives this whole pokie, and understanding where its return actually lives is the difference between playing it well and feeding it.

The engine is the Golden Pyramid wild, and the key word is multiply. In the base game, a single wild on a line is a modest boost: a ×2 to ×5 stamp on whatever that line was already paying. The maths only gets interesting when two or more wilds share a line, because then the multipliers compound by multiplication, not addition. Two ×5 wilds is a ×25 line, a ×5 and a ×4 is ×20, and these multi-wild lines build toward the 3,898× cap more than the high-pay symbols on their own. The single most useful thing to internalise is that the value is concentrated in the rare spins where the wilds stack, which is exactly the kind of distribution a medium-volatility label describes.

The Free Spins are where that engine compounds, because the wilds turn sticky and stay on the reels for the whole round. A wild that lands and locks early keeps applying its multiplier on every subsequent spin of the feature, and a second sticky wild sharing a line with it multiplies against it. That is the realistic path to the top end. But the round is capped at 15 spins and cannot retrigger, so the upside is finite by design. You are not waiting for a snowball that can run forever. You are banking sticky multipliers across a fixed, short window, and the value of any bonus is set by how many of them you lock and how often they end up on the same line.

That structure has a clean practical read. Because a fair chunk of the return lives in the base-game wilds rather than being locked behind the bonus, this is more active in the base game than slots where most value waits behind the feature. But the 95.01% RTP means every base spin still leaks more than it would on a 96-plus pokie, so the real bankroll variable is session length, rather than feature-chasing. The longer you sit on a sub-average game, the more the edge takes, and that is the lever you actually control.

Volatility distribution

No measured volatility figure is available for this title yet. It is roughly six weeks old, with no PAR-sheet leak and no community-tracked sample, so what follows is derived from the spec rather than measured off real play.

• Tom Horn labels the slot Medium, and every aggregator agrees, describing “average dispersion,” so the volatility band is settled the way the RTP debate sometimes is on other titles.
• The 3,898× cap is moderate, and the Free Spins are limited to 15 non-retriggerable spins, so the depth of the dry stretches is capped below high-volatility cascade or Megaways slots. Losses tend to accrue steadily rather than in violent swings.
• As a spec-derived class estimate, the standard deviation per A$1 staked sits in the medium band, well below the high-volatility extremes, which means a moderate bankroll buffer absorbs the variance.
• The honest translation: the variance is manageable, but the 95.01% RTP is the real drain. The thing that will quietly cost you on this pokie is less a brutal swing than the steady leak of a below-average return over a long session. These are spec-derived expectations, not tracked numbers, because no large-sample data exists for this release yet.

Demo notes

The live demo embedded on this page comes straight from Tom Horn’s own RGS demo gateway, and there are a couple of things to know about how it behaves.

• The demo comes through Tom Horn’s producer owned RGS gateway in fun play mode. Honestly, it is affiliate free, with only the single technical game id parameter in the URL. It also embeds cleanly because there are no frame blocking headers.
• The session is created fresh every time the page loads, so there is no stale token problem. Sure, reloading the page just kicks off a brand new demo session.
• The on screen balance uses the demo platform’s default fun mode currency instead of AUD. The currency parameter does not change it because the platform locks the display currency. Read the demo for the mechanics, not the money. In real play your operator serves AUD.
• The demo runs the 95.01% default config. That gives you a useful sanity check on the mechanics, mind you it does not confirm which tier a real money casino has integrated. Check that in the casino’s own info panel.

FAQ

Q: What is the max win on Giza’s Portals?
A: 3,898× your stake. You get there by stacking Golden Pyramid multiplier wilds on a single line until their multipliers multiply together, most realistically during the sticky wild Free Spins.

Q: Why does the 95.01% RTP matter?
A: It sits below the roughly 96% market norm, so the house edge is 4.99%. That is around one and a half times the edge on a 96.5% pokie, so your bankroll drains faster over a long session.

Q: How do the multiplier wilds work?
A: Every Golden Pyramid wild carries a random ×2 to ×5 multiplier. When two or more land on the same line, the multipliers multiply together. So a ×5 with a ×4 becomes ×20, not ×9.

Q: How many free spins does it award?
A: Up to 15. The number comes from what your Tomb Pick Up boxes reveal, rather than a fixed table. The round cannot be retriggered, so 15 is the hard ceiling.

Q: Should I use the Bonus Buy?
A: Buy Bonus costs 30× and Super Buy 100×. Well, on a 95.01% game neither improves the house edge. The 100× Super Buy is chasing a 3,898× ceiling, only about 39× its cost, so it is a high variance spend rather than value.

Q: Is it available to Australian players?
A: Only through offshore AU facing casinos. Tom Horn is Malta based and is not licensed under the Interactive Gambling Act 2001 to serve Australia directly. RTP is operator tunable, of course, so check the 95.01% figure in the in game info panel first.
