You know the game. You know how to play. In fact you probably know all there is to know. This is a great mobile version of the old favourite. The graphics are nice and clear with great kaboom effects when you score a direct hit. It has all the feel of playing the board game which is difficult to achieve and the computer ranges from being a beatable challenge to a tough old sea dog. The sound does all you want, some missiles away-style effects with a bit of booming and blasting when you get lucky. I really like this one, you should get it.
