Sea of Tranquillity is a new game that WMS brought out in late 2015. It has the usual five reels and thirty paylines, all of which are optional. Each line can be played for as little as 0.01 up to 5 coins. The highest bet value is 150 coins per sins for all of the lines. This makes Sea of Tranquillity a very appealing game to players of all budgets. The modern graphics and smooth game play will appeal to players of all experiences too, since the game is simple enough to be enjoyed by beginners but detailed enough for advanced players.
