Slots Like Atlantis Power Combo: Three Chest Scatters That Can All Fire on One Spin
Atlantis Power Combo puts a sunken city, a mermaid queen and a ghostly pirate on a 5 reel by 4 row grid with 40 fixed paylines, and it comes from Infinity Dragon Studios, the Australian team that ships everything it builds through Games Global. The published RTP is 96.40%, with stakes starting at £0.20 and topping out at £20.00 a spin. Three treasure chests sit above the reels, one red, one yellow and one green, and each colour hands you a different free spins mode: nudging wilds on a taller grid, a coin collection round tied to a four-tier prize ladder, or a random multiplier on every line win. That combining behaviour is what the Power Combo label actually buys you: two or three chests arriving on one spin run their modes simultaneously instead of forcing a choice between them. Most trackers call it high volatility, the studio calls it very high, and the ceiling is quoted at either 10,000x or 11,650x depending on the source. Anyone hunting slots like Atlantis Power Combo is really hunting that combining trigger, not another mermaid.

How the Game Works
Reviewed by Brian TaylorPublished: July 2026
SlotsLike may be paid a commission when a reader follows an operator link from this page. No commercial arrangement influenced this assessment of Atlantis Power Combo, and gambling is restricted to adults aged 18 and over.
The reels are framed by two stone pillars planted in a bed of gold coins, with ruined architecture fading into the blue behind them. It is a familiar picture and the studio has not tried to reinvent it. What the art does get right is legibility: the three chests above the grid are large, brightly outlined and impossible to miss, which matters enormously in a game whose entire appeal rests on noticing how many of them have landed.
Forty paylines pay left to right from reel one, three or more matching symbols are needed, and the wild only appears on reels two, three and four. That restriction is deliberate. The wild is a bearded Poseidon figure that arrives in tall stacks, and confining it to the middle three reels keeps the base game from paying too often while making a full stacked column feel like an event. It substitutes for everything except the chest scatters and the coin symbols, which are feature currency rather than paytable entries.
Running down the left of the screen is a four-tier prize ladder labelled Grand, Major, Minor and Mini. These are not shared progressive pots. Each tier is a fixed multiple of your current bet, which is why the numbers move whenever you change stake, and the Grand at the top is the 10,000x figure the game advertises on its own reels. Below the ladder sits a Buy Feature button on builds where that option is permitted. It is not available to players in Great Britain, so treat it as something you will see in the demo and not in a real money UK session.
Symbols and Paytable
The low end is card ranks nine through Ace, rendered in green and gold coral. The premiums climb through an octopus, a shark, a seahorse, a ghostly pirate captain, the red-haired mermaid Amphitrite and Poseidon himself. Line payouts are modest by 2026 standards, with the top symbol paying roughly five times stake for a full line of five, so nobody should expect the paytable to fund a session. Coin symbols are the other thing to watch: they carry a cash value printed on the face and do nothing at all in the base game, existing purely to be harvested once the yellow chest has started its round.
The Three Free Spins Modes
Red Chest: Nudging Wilds
Five free spins, and the grid grows from four rows to seven while they run. That takes the payline count from 40 up to 100. Any wild that lands then nudges to fill its entire reel, which on a seven-row grid means one wild symbol can become seven wild positions across a hundred active lines. This is the mode that produces the screenshots people share, and it is the reason the red chest is the one you want most.
Yellow Chest: Bonus Prize Collection
Ten free spins on the standard grid, and every coin symbol that lands is collected. Coins carry values between one and ten times stake. Alongside them are letter symbols that spell out the names of the ladder tiers, and completing a word awards that tier outright. This is the only route to the Grand, and it is why the yellow chest is a slower, more accumulative round than the other two.
Green Chest: Line Win Multiplier
Five free spins with a random multiplier applied to each winning line, drawn from 2x, 3x, 5x and 10x. On its own this is the weakest of the three, because five spins on a 40-line grid with a thin paytable does not give the multiplier much to work with. Its value is entirely in what it does to the other two.
How the Power Combo Actually Combines
Land two chests and both modes run across one round. Land all three and you get the taller seven-row grid, nudging wilds, coin collection and a line multiplier operating at once. That is where the arithmetic gets interesting: a nudged wild column on a hundred paylines, with a 10x multiplier attached to every line it completes, is a different game from anything the base spins suggest. The trade is obvious. Three chests in one spin is rare, and the yellow chest on its own, which is the most common single trigger, is also the least exciting to watch.
Pros and Cons
Pros
- The combining trigger is genuine rather than cosmetic, and a three-chest round plays nothing like a single one
- Expanding to seven rows and 100 paylines mid-feature is a real structural change, not a reskin
- 96.40% is at the upper end of the medium-high band and better than several rival Games Global releases
- The prize ladder gives the yellow chest a defined target instead of an open-ended coin grind
- The chests are large and clearly coloured, so you always know what round you are about to get
Cons
- Line payouts are weak, so dry stretches between chests are genuinely dry
- The green chest alone is a disappointing round for the anticipation it builds
- No feature buy for UK players, so there is no shortcut to seeing a multi-chest combination
- Sources cannot agree whether the ceiling is 10,000x or 11,650x, which is a poor look for a 2023 release
- The art is competent but generic, and it does nothing to distinguish this from a dozen other sunken cities
Game Screenshot
A base game spin with the Poseidon wild stacked down the whole of reel two. Three chest scatters sit in a row above the grid, coloured red, yellow and green from left to right, and gold coin symbols are scattered across reels one, three, four and five. The ladder on the left reads Grand $20,000.00, Major $1,000.00, Minor $100.00 and Mini $50.00, with a Buy Feature button beneath it, and the bar along the bottom shows $1,000.00 credit at a $2.00 bet. The capture is from a dollar-denominated demo build, so the ladder figures are ten thousand, five hundred, fifty and twenty-five times that stake.
Demo Play
What loads below is the studio build rather than a cut-down preview, so the trigger rate you observe is the trigger rate you will get. Spend a dozen spins on the Buy Feature button while you are here, purely to watch a three-chest round resolve, because that shortcut is closed to UK players on a funded account. Nothing won in demo mode converts to cash, and the usual age and location checks apply the moment you switch to real stakes.
Game Information
Expert Take
Three years of coverage have settled into a pattern, and the pattern is agreement on both halves of this game. The seven-row expansion gets named as the highlight almost every time, and almost every one of those same write-ups goes on to record how little the base game gives you to do while you wait for it. Our own view after a long session at 40p a spin is that Atlantis Power Combo is better designed than it is exciting. The three-mode structure is clean, the colour coding is smart, and the maths behind a full combination is properly generous. What lets it down is everything in between: a paytable that barely registers, a theme executed without personality, and a headline number that different sources report differently three years after release. It rewards patience and punishes anyone treating it as a session filler.
Similar Slots to Try
Two of these share the combining-trigger idea and two share the sunken city. None of them share both, which tells you how narrow this game sits.
The closest match on mechanic. Fortune Factory Studios run the same combining triggers on a smaller 5×3 grid with 20 lines at 96.00%, and push the ceiling higher to 12,500x.
Blueprint answer the same brief with a 6×5 Pay Anywhere cascade at 96.01%, where Poseidon’s Call stretches the grid to eight rows instead of seven. Same 10,000x ceiling.
Hacksaw keep the 5×4 shape and drop to 26 paylines at 96.27%, swapping three chests for a single Kraken collector. A calmer, medium volatility take on the same seabed.
ReelPlay abandon fixed lines entirely for 117,649 Megaways at 96.10%. Pick this one if the 40-payline base game here feels too static between features.
About the Developer
Infinity Dragon Studios was set up in Australia in 2018 and then spent four years invisible, because the studio had committed to building for Microgaming alone and Microgaming spent that period restructuring. Its first live title only arrived in 2022, once the distribution arm had become Games Global, and Atlantis Power Combo followed roughly a year later. Around 35 games have shipped since, all through the same network, with published RTP figures averaging close to 96.2%. The studio states on its own site that its maths favours high volatility and chasable wins, which is exactly what this game delivers. Chili Bonanza X UP holds the studio record at 50,000x stake, and nothing else in the catalogue comes near it. No other Infinity Dragon title has a full review here yet.
These three are the nearest comparisons currently on the site: all are Power Combo releases from other studios on the same Games Global network, so the trigger behaves the same way even though the studio badge differs.
Aurum Signature Studios build on the identical 5×4, 40-line frame at a matching 96.40%, also stretching to 100 lines in the bonus, and reach 12,320x.
Just For The Win compress the idea onto 5×3 and 20 lines at 96.05%, with a much lower 5,000x ceiling and a far quicker trigger rate.
Foxium drop paylines altogether for a 6×5 scatter-pays grid at 96.01%, showing how far the Power Combo wrapper stretches across different maths models.

Slots with the Same Features
Slots with a Four-Tier Prize Ladder
Grand, Major, Minor and Mini as fixed multiples of stake is a structure that turns up constantly on the Games Global network and beyond. The jackpot slots page gathers the other titles on the site built around fixed named tiers.
SpinPlay Games pair the same four named tiers with a lock-and-respin round at 96.49%, the higher RTP buying you a lower 5,000x ceiling.
Gameburger Studios also expand the grid in the bonus, going from three rows to six and from 10 lines to 25, with a 15,000x ceiling at 96.00%.
Atlantis and Undersea Slots
If the seabed rather than the trigger is what brought you here, the Atlantis slots and undersea slots pages have the full lists.
Relax Gaming run two stacked grids at once with scatter pays at 96.09%, a completely different engine reaching the same 10,000x ceiling.
Pragmatic keep the 5×4 shape but open it up to 1,024 ways at 96.41%, a gentler mermaid slot for players who want frequent small returns.
Slots That Collect Cash Symbols
The yellow chest turns coins into the whole point of the round. Other games build their entire feature set on that idea, and the money collect feature page lists them.
Yggdrasil put cash symbols on a 6×4 grid with 4,096 ways and a 6,000x ceiling, though the 94.00% default RTP is a long way below what you get here.
Four separate X UP scatter types feed one running cash total, a faster and noisier version of the coin harvest the yellow chest sets up.
Frequently Asked Questions
How does the Power Combo bonus work in Atlantis Power Combo?
Three coloured treasure chests act as scatters. Red awards five free spins with nudging wilds on a grid that grows to seven rows and 100 paylines, yellow awards ten free spins that collect coin values and ladder letters, and green awards five free spins with a 2x to 10x multiplier on line wins. Any chests landing on the same spin combine, so all three together give you the tall grid, the nudging wilds, the coin collection and the multiplier running as one round.
What is the RTP of Atlantis Power Combo?
96.40%, which sits near the top of the medium-high band running from 96.00% to 96.49%. Games Global supplies alternative maths configurations to individual operators, so the number shown on the help screen at the site you are actually playing is the one that governs your session.
What is the maximum win in Atlantis Power Combo?
Sources disagree, and it is worth knowing that before you sit down. Infinity Dragon Studios states 10,000x total bet, and the game itself carries a Win Over 10,000x Bet banner beside the reels. Several review databases list 11,650x instead. The Grand tier of the prize ladder is the practical route to the ceiling and is set at 10,000x stake.
How volatile is Atlantis Power Combo?
High, and the studio itself goes further and rates it very high. Either way the shape of the game is the same: thin line payouts, long gaps between chests, and almost all of the value concentrated in rounds where more than one chest has landed. Budget for that before choosing a stake.
What are the best slots like Atlantis Power Combo?
333 Fortunes Ahoy Power Combo is the closest on mechanic, using the same combining triggers on a tighter 5×3 grid. Dawn Of The Vikings Power Combo is the closest on structure, matching the 5×4 shape, the 40 to 100 payline expansion and the 96.40% RTP exactly. For the theme rather than the maths, Rise Of Atlantis 2 and Marlin Masters Atlantis are the better picks.
Can I play Atlantis Power Combo for free?
Yes, and the demo sitting further up this page is the one to use, since it loads the studio build rather than a simplified preview. Give it long enough and you will see for yourself how seldom a second chest joins the first. Nothing won there converts to cash, and age and location checks apply once you move to a funded account.
Who makes Atlantis Power Combo?
Infinity Dragon Studios, an Australian studio founded in 2018 whose games are distributed exclusively through the Games Global network. This was one of its earlier releases, arriving in mid 2023, roughly a year after the studio finally got its first title live.
Is there a bonus buy in Atlantis Power Combo?
The game ships with a Buy Feature button that lets you purchase a chosen free spins mode, but it is not offered to players in Great Britain, where feature buys are not permitted. You will see the button in the demo and not in a UK real money session.
Our Verdict on Atlantis Power Combo
There is a very good twenty seconds inside this game. A three-chest trigger, seven rows of reels, a wild nudging into a full column and a 10x multiplier landing on top of it is as satisfying a sequence as anything the Games Global network has produced. Getting there is the problem. The base game gives you almost nothing, the green chest on its own is an anticlimax, UK players cannot buy their way to a combination, and a game released in 2023 still has two different maximum win figures circulating. Recommended if you like a slot that saves everything for one moment and you have the bankroll to wait for it. Skip it if you want a game that keeps you company between features.
