Dolphin Reef slots takes players down to the gorgeous blue seas where they see the jumping dolphin alongside many other fish and some hidden treasure. There are five reels and twenty paylines in this game that allows players to try it out for fun before placing real money bets. There is also an auto start/stop function that allows the player to start the game immediately and stop the spinning reels before the natural stop of the reels. Players may place bets on all of the paylines or one or a few of them depending on their preference. The player can choose coin sizes ranging from $0.01 up to $10.
In this game the dolphin is naturally the wild symbol. This dolphin only appears on reels 2 and 4. When he does appear on the reels he expands and is able to substitute for other symbols. When the dolphin appears on both these reels together the two reels stay in place and the other reels; 1, 3 and 5 are re-spun 5 times with the expanded dolphin on reel 2 and 4.
The treasure chest is the scatter symbol and this offers players multiplying payouts if three or more appear on the screen. Three of the treasure chests award players 3x the coin bet placed, four of the treasure chests award players 10x the coin bet placed and five of the treasure chests award players 100x the coin bet placed.
Players who want to try and increase their winnings are invited to choose the optional gamble feature at the end of a winning spin whether from the re-spins or the standard spins. The gamble feature takes place on a separate screen where the player is invited to guess the color or suit of a card to be turned over. Guessing the color of the card correctly doubles the winnings for that spin and guessing the suit of the card to be turned over quadruples the winnings for that spin. The player may continue with the gamble feature until he loses or he reaches his gamble limit at which point he is taken back to the main game. The calming waters where the dolphin lives are a great setting for this game that includes re-spins and the special gamble feature, all giving the player more chances to win.
