I've been playing Warship HD and really like the immediate intuitive simplicity of the game.... no instructions needed. But, without any formal tutorial or in-game instructions I can't figure out what the numbers in the lower left hand side of the screen stand for? I know that one of them stands for the number of ships left, but what are the other two for? 1/4, 3/3, 1/5, etc.... Can anyone clear this up for me?
