How Atlantis Megaways plays
The game runs on the Megaways engine, so every reel lands with its own height, from 2 symbols to 7. A win needs three or more matching symbols, or only two for Poseidon (shown as 2x for 2 in the Symbol Pays section in our lobby), and the number of ways changes from spin to spin with the reel heights, from 324 at the lowest to the full 117,649.

Two treasure chests on the reels are marked 3.00 and 0.60, and a shell is marked x10. The bar above the game shows Net Balance, £0.00 here, and Time elapsed; UK rules require online slots to show time played and net position. Game and artwork © Yggdrasil, developed with ReelPlay.
Card royals make up the low end of the paytable, with sea creatures such as the seahorse above them and Poseidon at the top. A win does not end the spin. The winning symbols are cleared and new ones drop into their places, a cascading reels chain that continues while fresh wins keep forming. Treasure chests are the scatters, and they matter only for the respins feature.
The Jackpot Respins
Six or more treasure chests anywhere on one spin open the Jackpot Respins. The round starts with 3 respins, and the chests that triggered it stay locked where they landed. Every new chest that lands is held as well and keeps the respins going, so the round runs on for as long as chests keep arriving. If no new chest lands, the respins count down to the end and each chest left on the reels pays out.
The four jackpots
Four jackpots are named in the respins: Mini, Minor, Major and Grand. They are fixed prizes set as multiples of the total stake, and the key facts list the Grand. The two smaller ones can turn up more than once in the same round, while the Major and the Grand can each be won only once per round. The jackpots are won inside the respins, so every route to them starts with a chest trigger in the base game.
Atlantis Megaways compared with Atlantean Treasures Mega Moolah and Lord of the Ocean
Two other games with guides of their own take a simpler route to their bonuses. Atlantean Treasures Mega Moolah keeps a 5x3 layout with 10 paylines, and its jackpots are progressive: collected pearls set off a wheel of four. Lord of the Ocean, also 5x3 with 10 lines, has no jackpot and leans on 10 free spins with an expanding symbol. Atlantis Megaways is the one with changing reel heights and cascades, and its jackpots are fixed multiples of the stake, won inside a respins round rather than from a growing pool.
| Game | Grid and lines | Main feature |
|---|---|---|
| Atlantis Megaways | 6 reels of 2 to 7 symbols, up to 117,649 ways | Jackpot Respins with four fixed jackpots |
| Atlantean Treasures Mega Moolah | 5x3, 10 paylines | Collected pearls trigger a wheel of four progressive jackpots |
| Lord of the Ocean | 5x3, 10 paylines | 10 free spins with an expanding symbol chosen before the round |

Frequently asked questions
What kind of game is Atlantis Megaways?
It is a six-reel Megaways video slot with a sunken city theme, made by ReelPlay and released by Yggdrasil. Most of its action comes from cascading wins in the base game and from the chest-triggered respins. There is no free spins round, and no separate bonus game: the respins carry the four jackpots, while the base game relies on its cascades.
How many ways does the Atlantis Megaways slot pay?
The count depends on how tall each reel lands. With the reels at their lowest the game pays 324 ways, and with all six reels showing 7 symbols it reaches 117,649. A spin with mixed heights lands somewhere in between, and each new spin sets the heights again.
What does a treasure chest do outside the respins?
On a normal spin a chest is only a scatter waiting for company. Five or fewer do not start anything, and the round needs six or more on the same spin. Once the respins begin, chests change role: they lock in place, extend the round and carry the values and jackpots that pay out at the end.
