Features
Wilds
The dolphin is the wild symbol and it can substitute for all the other symbols, including the scatter, to help and complete winning combinations.
Scatter
There is a treasure chest scatter symbol and it offers scatter payouts of up to 100x the total bet.
Bonus Features
The dolphin wild doubles as the bonus symbol and when it lands on reels two and four simultaneously the free spins begin. You are awarded five free spins during which reels two and four are completely wild.
The slot also offers a gamble feature that can be used after any winning spin to try to double your payout. It is a simple guessing game where you need to decide if the next card drawn from a pack will be red or black. If you pick correctly then you can try again.
Jackpot
Dolphin Reef offers a top payout of 5,000x for landing five tropical fish symbols along a payline. The turtle can payout up to 1,000x and the seahorse and starfish can both payout up to 500x. It is also worth noting that the high value symbols will payout when just two land along a payline.
