You face a computer rival in a tabletop duel with red and blue marbles. You choose a red marble, aim in secret, and strike at the same time as your rival. You try to hold the center and be first to 5 points.
The marbles roll across a round green table with a marked center. An aiming line and power meter show your shot before both sides strike. If a marble is knocked out, it returns next round.
