This game is far and away my favorite of all atari games. It is incredibly fun, addictive, and challanging, three things that many atari games lacked. The arcade version is much more elaborate, with a dragon, and a fireball bouncing around rather than a block of ?. You have the ability to hold onto the ball in both the arcade and atari versions, but in the arcade, if you hold onto the ball small tongues of fire continue to deteriorate your wall. This game has led to many sore arms on my part from when I beat my older brother, and he proceeded to pound me. I love this game.
