KJumpingCube is a simple tactical game. You can play it against the computer or a friend - or you can set up a game between two computer players and just watch. The playing area is a box of cubes containing points. When the game starts each cube has one point, no owner and a neutral color. If you click on a neutral cube it becomes yours, changes to your color and increases by one point. Your objective is to capture all the cubes, but now it is your opponent's turn.
