About Undines’s Deep

Theme and Graphics

Immersive Underwater World

Set in the depths of the ocean, the game features the adorable mermaid Undine and an abundance of sea life on a 5×3 reel grid. The underwater setting is complemented by translucent reels and seaweed decorations, creating a visually stunning experience​​​​.

Aesthetic and Sound Design

The high-definition graphics bring to life a variety of marine life, including jellyfish, starfish, and seahorses. The symbols fit the theme perfectly, with even the playing card symbols designed to blend into the underwater motif. The ominous and suspenseful soundtrack adds to the game’s allure, enhancing the overall experience​​​​.

Gameplay and Features

Game Mechanics

Undine’s Deep offers a standard 5-reel, 10-payline format with a user-friendly interface. Players can choose from low, medium, or high-risk levels and adjust their bets using a simple control system. The betting range is from 0.01 to 100 credits per spin, making it accessible for both casual players and high rollers​​​​.

Special Features

  • Wilds and Scatters: The game features a goldfish as the wild symbol and a flame-haired mermaid as the scatter. The wild substitutes for all symbols except the scatter, doubling payouts when involved in a win.
  • Free Spins and Multipliers: Landing three or more scatter symbols triggers 15 free spins with a 3x multiplier. This feature can be re-triggered during the free spins round​​​​.
  • Gamble Feature: A unique gamble feature allows players to boost their winnings by selecting a higher card than the dealer’s. However, a lower card will end the round and forfeit the winnings​​.
