Waves of Poseidon by Pragmatic Play is a 6x5 online slot set in an underwater Greek-mythology theme. The game uses a tumble system, where winning symbols are removed and replaced by new ones in the same spin sequence. An RTP of 96.55% is listed, with high volatility and a maximum stake range shown in the game data.
The layout includes a separate multiplier reel on the left side of the grid. Multipliers can increase through consecutive tumbles, reaching up to 20x when a BONUS symbol is activated. BONUS symbols may also carry their own multipliers of up to 50x in the base game, which can add to the value of winning combinations.
Landing 4 or more scatter symbols triggers the free spins feature, with 10 to 20 free spins awarded depending on the number of scatters. In this bonus round, the multiplier reel starts unlocked, and BONUS symbols are guaranteed to carry a multiplier. A Super Free Spins mode is also available with 6+ scatters, where the multiplier reel does not reset between spins. The demo version can be used to play for free and practice before playing for real money.
