Way down under the waves sits the lost city, and that's where Atlantis World plants its 5×3 reels. GameArt put this one out back in 2015, so yes, it shows a little age in the animations. But the art still works. Sunken columns, gold-and-pearl trim around the grid, light filtering down from somewhere far above. Poseidon scowls from the top of the paytable next to a pink-haired mermaid, a golden seahorse, and a leaping dolphin. The lower symbols are the usual jewelled card royals, just dressed up in ornate plaques.
Fifty paylines run left to right across the grid. The dolphin is the star here, and it pulls a double shift: it's both the highest-paying icon and the Wild, and it shows up stacked. When a full reel comes back coated in dolphins, that's usually where the bigger base-game money lands. It subs for everything except the Sphere, a golden astrolabe that works as the Scatter.
Here's the catch with that Scatter. You need three of them, but they only register on the middle three reels, so the free spins trigger is pinned to reels 2, 3 and 4. Land it and you get five free spins. Only five. That sounds stingy, and on paper it is, until you notice the bonus runs on its own reel set seeded with extra stacked dolphin Wilds. That full-reel coverage that's occasional in the base game? It becomes routine during the round. Three more Spheres mid-bonus add another five spins, and with such a short round to begin with, a single retrigger almost doubles the action.
And that's basically the whole feature list. There's a standard GameArt card gamble parked after each win if you fancy a red/black or suit guess, but no buy option and no jackpots. Lean by today's standards, honestly. RTP sits at 96.01%, volatility lands medium-high, and the ceiling reaches 2,121x your stake when those bonus reels cooperate. Bets stretch from 0.25 up to 100 a spin.
