RTP Undine's Deep is a 5x3 slot from Endorphina with 10 paylines, a 96.07% RTP and high volatility. The game is set in an ocean theme and includes standard reel symbols such as seastar, seahorse, gold fish, jellyfish, seashell and card ranks. Players can use the demo version to play for free and practice before playing for real money.
The Scatter is represented by mermaid Undine. Three Scatters trigger 15 free games, while landing five Scatters awards a payout of 500x the base bet. During the free spins round, all wins are multiplied by x3, and the feature can be retriggered. The Gold Fish acts as the Wild, substituting for all symbols except Scatter and doubling a win when it completes part of a winning line.
Additional features include the Risk Game and Bonus Pop, depending on jurisdiction and casino availability. Top-paying symbols include the starfish and sea urchin, each paying 75x the base bet for five of a kind. The game is available in regulated markets only, with betting options ranging from 0.1 EUR to 90 EUR.
