Master of Atlantis

Master of Atlantis: Blueprint Gaming Goes Beneath the Waves

Master of Atlantis is a mythology-themed online slot from Blueprint Gaming, played out in the depths of the legendary lost city of Atlantis with the sea god Poseidon as its central figure. Built as a 5-reel, 4-row slot with 40 paylines, it's a departure from some of the studio's more sprawling ways-to-win releases, opting instead for a more traditional structure.

Theme and gameplay feel

Set firmly on the seabed, dark ocean blue dominates the colour palette throughout, with animated bubbles drifting toward the surface and seaweed swaying in the current. Cartoon-style graphics and a soothing background soundtrack give Master of Atlantis a relaxed, chill atmosphere that contrasts nicely with the high stakes on offer. Card suit symbols styled in a Greek-inspired font make up the lower end of the paytable, while pearls, treasure chests, sharks, krakens, and the game's logo symbol carry the bigger rewards — the logo alone pays 20x the stake for five of a kind. An Omega-shaped wild substitutes for all symbols except the scatter.

Reels, paylines and betting range

Master of Atlantis is playable across any device, with stakes running from 0.50 up to 100 per spin, positioning it more toward mid-to-high rollers than casual small-stake players.

RTP and what it means for you

The game carries a theoretical RTP of 96.08%, a solid figure that sits above the typical industry average, giving players a reasonably competitive long-run return relative to many other titles in the mythology genre.

Volatility and features

Rated medium volatility, Master of Atlantis balances its win frequency with a Trident Strike feature that can randomly trigger during the base game, adding mystery bubble symbols to the reels that transform into a single randomly chosen symbol once they settle, boosting win potential across the board. The main event is the Poseidon Free Spins round, triggered by landing 3, 4, or 5 scatter symbols, which awards a set number of spins and introduces Trident Power Spins to help chase bigger combinations. The maximum win reaches 10,000x the stake.

Verdict

Master of Atlantis brings a calmer, more traditional structure to the mythology slot genre, backed by a competitive 96.08% RTP, medium volatility, and a solid 10,000x ceiling via its Poseidon Free Spins. It's a good fit for players who want mythological theming without the extreme swings of a high-variance release.
