Master of Atlantis

Blueprint Gaming sets Master of Atlantis beneath the waves in a cartoon-styled telling of the lost city, built on a 5-reel, 4-row grid with 40 paylines. Deep ocean blue dominates the backdrop, with bubbles drifting upward and seaweed swaying in the current beneath a calm, ambient soundtrack — a departure from the studio's usual high-energy visual style.

Card suits from A down to 9 fill the lower end of the paytable, styled in a Greek-influenced font, while pearls, treasure chests, sharks and krakens sit above them. The game's own logo tops the regular paytable, paying 20 times the stake for five matching symbols in a row. An Omega symbol serves as the wild, substituting for everything except the scatter.

Trident Strike can fire at random on any base-game spin: Poseidon's trident is thrown down onto the reels, seeding a set of bubble mystery symbols across the grid, and when the reels settle those bubbles all transform into a single matching symbol to build out extra wins.

The Poseidon Free Spins round opens when 3, 4 or 5 scatters land anywhere on the reels, handing out 5 free spins along with 1, 2 or 3 Trident Power Spins depending on the number of scatters. The goal during the round is to gather trident symbols: collecting 5 in total pays 1 times the stake, while reaching the full 20 pays out 100 times the stake. Once that ceiling is reached, every scatter symbol that lands afterward pays the full 100x value on its own — land five scatters on one spin at that stage and it returns 500 times the total stake, on top of anything else the spin pays out. A separate Poseidon scatter can also appear during the round, presenting four treasure chests to choose from; picking one reveals either more free spins or additional Trident Power Spins.

Master of Atlantis runs at medium volatility with a 96.08% RTP and a maximum win of 10,000 times the stake. Stakes span 0.50 to 100 per spin, spreading returns across the Trident Strike feature and the scatter-collection free spins rather than a single standalone bonus round.
