Dive deep into Poseidon’s mysterious world with Net Gaming’s Mystic Ocean online video slot. The game is played on a standard 3×5 game grid submerged deep into the ocean. Its symbols are represented by different sea creatures, such as fish, octopuses, sea turtles, and more. Keep playing until 3 bonus symbols appear anywhere on the reels and trigger 10 free spins with special expanding symbols. This bonus game is the only one available.

The bonus symbol doubles as the wild and substitutes for all other symbols, except for the special expanding symbols during the free spins game. When one of these symbols appears on any reel during the free spins, it expands to replace all other symbols on the said reel, paying out on all pay lines. Every time you win, you can use the gamble feature to double your winnings up to four times in a row by choosing between a blue or a red card. Mystic Ocean online video slot has an expected payback rate of 96.50%.
