About the Underwater Theme of Dolphins Treasure
Dolphins Treasure plunges players into the unexplored ocean depths in search of long-lost treasure. The visuals depict a vibrant marine life scene, with fish swimming amongst colourful corals and seaweeds.

The atmosphere is calm yet adventurous, perfectly capturing the allure of hidden riches beneath the waves.
Dolphins Treasure Bonus Features Explained
Bonus Game
The Bonus Game is triggered when Cash-on-Reel values land on the reels. This activates the Ultimate Fast Cash feature, a Hold & Spin round where players can unlock additional rows by landing more Cash-on-Reel values. If a Super Fast Cash coin appears during this round, the game transitions to Super Fast Cash - an enhanced Hold & Spin feature with larger credit prizes and a chance to win the Super jackpot prize. Reel growth and prize upgrades make this bonus highly engaging.
Free Spins
The Free Spins feature is known as the Big Symbol Free Games. During this round, the middle three reels spin together as one large 3x3 symbol. If a single big Cash-on-Reel value lands, it immediately awards the Ultimate Fast Cash feature. This combination of oversized symbols and potential re‑trigger of the bonus adds depth to the free spins experience.
Wild Symbol
The Wild Symbol substitutes for all other standard paying symbols to help form winning combinations on the 9 paylines. It does not replace Scatter or Cash-on-Reel symbols but increases the chance of hitting a paying line.
Scatter Symbol
The Scatter Symbol activates the main bonus features when enough appear on the reels. In Dolphins Treasure, the Scatter is effectively the Cash-on-Reel symbol - landing multiple such symbols triggers the Ultimate Fast Cash Hold & Spin round or other bonus events as described above.
How to Play Dolphins Treasure Slot
Playing Dolphins Treasure is straightforward. Start by setting your bet using the plus and minus controls; the bet range runs from 0.10 to 500 per spin.
