Dolphins are very popular animals because of how smart and majestic they are. All providers of online casino software offer slots with dolphins, and two of the biggest providers – Microgaming and Playtech – offer more than one of them.

In Dolphin Reel by Playtech the symbols are fish, seahorse, starfish and turtle. The wild symbol is dolphin. It can only appear on reels 2 and 4. A free spins feature gets triggered if it appears on both. The two reels become fixed and the other three reels get re-spinned five times. The Playtech gamble game is also available.

Dolphin Cash, also by Playtech, is much newer and very visually attractive. The underwater background is animated. Shifting Wilds is a special feature available – the dolphin wild symbol originally appears on reel 5, but then it keeps moving to the left reel by reel. So a wild symbol is going to stay for the next four spins once it appears. The XtraWin feature means that by increasing the bet by 50%, the wild symbol can split in two and move to the left like that.

Dolphin Coast by Microgaming has a huge number of ways to win – 3125. Other attractive features are the bonus game on the reels, the free spin feature and the Microgaming gamble game.

Another Microgaming game called Dolphin Tale is humorous and cartoonish. The wild symbol is a dolphin who’s a rookie policeman. Other animals play roles too, for example the fish is a policewoman and the walrus is a police chief. The animations are great.

Microgaming dolphin-themed game can be played at Spin Palace or Royal Vegas, while the Playtech ones are available at Omni Casino or Mansion Casino.
