The Ball Game Description:

The best Tetris-style game to come along in years!
Play against the computer or play along with a friend in two player mode. As balls fall from the top of the play board, arrange them in groups of four to knock them off the board.
If the board fills up, the ball spill out and you lose.
Watch out for the bowling balls, which can only be knocked out if a ball next to them is knocked out.
Knock out multiple groups of balls to increase your score and drop more bowling balls on your opponent.
