Released in 2020 as the underwater twin of Hypernova Megaways, it shares that game’s exact maths and reactive cascade engine while swapping deep space for the sunken city.

Pros and Cons

Reviewed by Paul Stone
Published: September 2018

Pros

• The Pearl Jackpot Respins lock every chest and clam scatter in place and reset the respin counter to three on each new hit, so a busy trigger builds genuine tension as the grid slowly fills with coin values and jackpot symbols.
• Chest scatters each carry a visible 1x to 100x coin value during the respins, so you can watch your potential payout climb before the round even ends, a clearer reward signal than most respin features give you.
• Four fixed jackpots (Mini, Minor, Major and the 2,000x Grand) sit on top of the coin wins, giving the bonus a top-heavy payout structure rather than relying on a single multiplier.
• The underwater art and the extra horizontal top reel make it the better-looking of the two ReelPlay Hypernova-engine slots, the visual upgrade over Hypernova Megaways is the main reason to pick this version.

Cons

• There are no free spins at all, the entire bonus is the Pearl Jackpot Respins, so anyone expecting a Megaways free-spins round with a building multiplier will be disappointed.
• The 8,641x stake ceiling is low for a Megaways slot, many rivals on the same mechanic reach 20,000x to 50,000x, so the headline win potential is modest.
• The maths is a straight clone of Hypernova Megaways, so if you have played that game there is nothing new here beyond the theme.
• The respins trigger needs six or more scatters in a single sequence, which lands rarely, so long dry spells in the base game are common between bonuses.

How the Game Works

Atlantis Megaways runs on six reels that each drop between two and seven symbols per spin, plus a horizontal reel of four extra positions sitting above reels two to five. When the reels are maxed out you get the full 117,649 ways to win; on a quiet spin the count can fall as low as 324 ways. Wins are paid left to right on matching symbols in any position on consecutive reels, and every win triggers a cascade, winning symbols are removed and new ones drop in to fill the gaps, with the reactions continuing as long as fresh wins keep landing.

Symbols and Paytable

The high-value symbols are the underwater characters and treasures of the lost city, while the low values are the usual royals styled in an oceanic palette. A wild substitutes for all paying symbols. The two symbols that matter most are the treasure chest and pearl clam scatters, they do not pay in the base game but together they trigger and feed the Pearl Jackpot Respins, where the real money is made.

Pearl Jackpot Respins, the only bonus

Landing six or more treasure chest and pearl clam scatters in one spin sequence triggers the respins. The current number of Megaways and all the triggering scatters lock in place, every other position blanks out, and you start with three respins. Each new scatter that lands locks in and resets the counter back to three, so the round only ends when you run out of respins or the screen fills completely. Treasure chests are marked with a random coin win from 1x to 100x your bet; pearl clams award one of the four fixed jackpots, topping out at the 2,000x Grand. This is the closest a slot like Atlantis Megaways gets to a free-spins round, and the slowly filling grid is where all the anticipation lives.

Cascading Reactions

Every base-game win sets off a Reaction: the winning symbols vanish, symbols above drop down, and new ones fall into the empty spaces. Because the ways-count is recalculated on each drop, a single lucky spin can chain several reactions together. There is no win multiplier climbing through the cascades, though, which keeps base-game payouts more modest than on Megaways slots that ramp a multiplier with each consecutive reaction.

Similar Slots Worth Trying

If you like slots like Atlantis Megaways, the closest matches mix Megaways structures with fantasy or mythical themes. These four are good starting points, each picked for how their reels and features compare to ReelPlay’s underwater grid.

King Maker
A Big Time Gaming Megaways title from 2019, King Maker uses the same dynamic-reels idea on a medieval theme. Its volatility runs lower than Atlantis Megaways and it does include a free-spins round, so it suits players who found the lack of free spins here frustrating.

Aurora Wilds
Mutuel Play’s Aurora Wilds is a simpler 5×3, 10-payline slot with a 96.20% RTP and medium-low volatility. It is a gentler, mystical-themed alternative for players who like the Atlantis atmosphere but want a calmer, more traditional payline game.

Avalon 2
Microgaming’s 2014 Avalon 2 is an Arthurian-legend slot with 243 ways, a 95.92% RTP and a multi-stage Grail Bonus of eight different free-spins modes. It trades Megaways volatility for a deep, structured bonus, making it a richer feature game than Atlantis Megaways.

5 Knights
NextGen’s 5 Knights is a 2013 medieval slot on 25 paylines with a 95.35% RTP, free spins and win multipliers. It is the most dated of the four, but its multiplier-driven free spins offer the rising-reward feel that Atlantis Megaways deliberately leaves out.

More Lost-City Games

Strip away the underwater art and this is a Megaways game first and an Atlantis game second, but the lost-city setting is the reason most players pick it over its space-themed twin. If the sunken city is what you are after, there are plenty of games similar to Atlantis Megaways below.

Our favourite Atlantis slots

Atlantis is one of the most reused themes in slots, so there is no shortage of games like Atlantis Megaways if it is the sunken-city setting you are after rather than the Megaways engine specifically.

Under the polished underwater art, remember this is mechanically a Hypernova Megaways clone, the symbols and colours change but the maths, ways-count and Reaction engine are identical to that earlier space-themed release.

If you simply want more of the lost-city theme, similar slots to Atlantis Megaways include Atlantis Thunder, Atlantis Queen and the original Atlantis, each takes the same mythical setting in a different direction.

Other Atlantis-themed demos worth a spin include Atlantis Slot, Atlantis Queen and Atlantis Thunder.

More From ReelPlay

ReelPlay is an Australian games studio (formerly Chance Interactive) best known for inventing the Infinity Reels mechanic and for building the Hypernova/Megaways engine that powers this slot. Rather than running its own casino brands, ReelPlay distributes most of its titles through Yggdrasil’s YG Masters partnership programme, which is how Atlantis Megaways reaches UK-licensed casinos.

The studio rebranded from Chance Interactive to ReelPlay in 2019 and has since become one of the more prolific suppliers on the YG Masters platform, collaborating with other small studios to publish their games too.

Notable ReelPlay titles include Hypernova Megaways (the engine twin of this slot), Odin Infinity Reels Megaways, El Dorado Infinity Reels and Gems Infinity Reels. Atlantis Megaways matters in their catalogue as the second outing for the Megaways version of their engine, and the one that proved the theme, not the maths, was the real selling point.

Two ReelPlay titles show the studio at its most inventive: Odin Infinity Reels Megaways pairs the Infinity Reels expansion with a Megaways count, and El Dorado Infinity Reels builds wins through endlessly added reels rather than cascades. Both swing harder than this slot, so they are natural next steps if you want bigger ceilings from the same developer.

Frequently Asked Questions

What RTP does this slot run at?

Atlantis Megaways runs at 96.10% RTP, marginally above the 96% industry average. Some operators may configure a different RTP, so it is worth checking the paytable at your casino before you play.

Does it have a free-spins round?

No. Unusually for a Megaways slot, there is no free-spins round at all. The single bonus is the Pearl Jackpot Respins, triggered by six or more chest and clam scatters in one spin sequence.

What is the maximum win?

The maximum win is 8,641x your stake. That is low for a Megaways game, many rivals reach 20,000x or more, so the appeal here is the jackpot respins and the look, not a huge top prize.

How do the Pearl Jackpot Respins work?

Land six or more chest and clam scatters and the triggering scatters lock in for three respins. Each new scatter resets the counter to three. Chests pay 1x to 100x your bet and clams award one of four fixed jackpots, up to the 2,000x Grand.

Is it the same game as Hypernova Megaways?

Mechanically, yes. Atlantis Megaways uses the identical engine, maths and feature set as ReelPlay’s earlier Hypernova Megaways, only the theme changes, from deep space to the sunken city.

What are some slots like Atlantis Megaways?

For the Megaways mechanic try King Maker or Bar X Safecracker Megaways; for the Atlantis theme try Atlantis Thunder, Atlantis Queen or the original Atlantis. Each is a fair alternative depending on whether you want the engine or the setting.

Who developed this slot?

It was developed by ReelPlay, an Australian studio, and distributed to casinos through Yggdrasil’s YG Masters programme. Please gamble responsibly; this game is for players aged 18 and over.

Our Verdict on Atlantis Megaways

Atlantis Megaways is the prettier face of ReelPlay’s Hypernova engine, and that is both its strength and its limit. The Pearl Jackpot Respins, the locking scatters and the four fixed jackpots give it a clear hook, but the missing free-spins round and the modest 8,641x ceiling hold it back from the top tier. It is for players who want a good-looking underwater Megaways game with a respin bonus to chase, not for those hunting a big multiplier free-spins round, who will prefer slots like King Maker or the bigger-paying Megaways titles. A solid, well-made clone rather than an essential one. If you want the best slots like Atlantis Megaways with a proper free-spins round, King Maker and the bigger-paying Megaways titles are the alternatives to reach for first.
