In the game of four square, there are four different games you are playing all pretty much at the same time. The good thing though is that they all use the same controls, the arrow keys. There is just a difference in how each game uses them. Kossack Kubes will have you use the arrow keys to move left or right with the left or right arrow keys. The down key will drop a piece and the up key will rotate it. Space invasion has you using the left and right keys to move your ship while the up key will fire missiles. Dr. Pills uses the left and right to move, down to drop a pill, and up to rotate. Then the final game, BrickBreaker, just has you use the left and right keys to move. Although if you should lose at any of the one games, its game over for you.
