Dolphin Reef by Playtech — RTP & Analytics

Dolphin Reef is a 5-reel, 20-payline video slot by Playtech with an underwater theme featuring marine creatures including starfish, turtles, seahorses, and clown fish as high-paying symbols. The game employs a dolphin wild symbol that functions as a substitute for all symbols except scatters, and a treasure chest scatter that awards multipliers up to 100x the wager when five appear on the reels. The primary bonus mechanic triggers when dolphin wilds land simultaneously on reels 2 and 4, expanding to cover those reels completely while the remaining three reels spin 5 times with the expanded wilds locked in place, increasing winning combination potential. The game includes a double-up gamble feature allowing players to risk winnings by predicting card color (doubling wins) or suit (quadrupling wins) up to 5 consecutive times. With an RTP of 96.03% and medium-high volatility, Dolphin Reef offers flexible betting from 0.01 to 3000 coins per spin and is optimized for mobile play across all devices.
