Animals such as cats, dogs, monkeys and dolphins among others are the most loved animals by people from all over the world, including myself. Therefore, it is quite obvious that casino software and game developers create and develop a range of slots that focus on these creatures. Slots developer Aristocrat is one of them. Dolphin Treasure is a video slot created by Aristocrat that has an underwater theme and puts the dolphins in the spotlight. If my memory serves me right, it was first released at land based casinos in Australia more than 15 years ago. The slot supplier also released the game on the Internet and it plays the same as the original slot machine. You can play it at online casinos that offer bitcoin gaming in both free and real money mode. To sum it up for you, Dolphin Treasure is a 5 reel, 20 pay-line video slot that comes with a wild and a scatter symbol, retriggering free spins bonus round and a multiplier that doubles your wins.
