How the Game Plays

Undine's Deep takes players into a serene underwater kingdom ruled by the mermaid Undine. This Endorphina classic features a standard five-reel grid populated by various marine life, including seahorses, starfish, jellyfish, and seashells. Winning combinations are formed by landing matching symbols from left to right on the active paylines. The Goldfish acts as the Wild symbol; it not only substitutes for others to complete wins but also applies a 2x multiplier to any payout it helps create.

Free Spins Explained

The main attraction is the Free Games feature, triggered by landing three or more Undine Scatter symbols anywhere on the reels. This awards 15 free spins. During this round, a global 3x multiplier is applied to all winnings, significantly boosting the payout potential. If the Goldfish Wild participates in a win during this mode, the combined multipliers can lead to substantial rewards. The feature can also be retriggered by landing additional scatters during the bonus.

Bonus Pop & Risk Game

For those who prefer direct action, the Bonus Pop feature allows for the immediate purchase of the Free Spins round. Additionally, this slot includes the signature Endorphina Risk Game. After any win, players can choose to gamble their prize by picking one of four face-down cards. If the selected card is higher than the dealer's card, the win is doubled; however, a lower card results in the loss of the entire payout.
