Gameplay
Ball Jacks is a futuristic action game that involves an ultra-competitive sporting event. Two robot crabs are controlled by men who play the game merely to become wealthy and famous. There is a conveyor belt behind them that spews metal balls at them. The goal is to capture balls that belong to the opponent and keep them from him until time runs out. Balls can also be knocked out from the mechanical hands of the opponent. All damaged crabs must return to the pit area for a quick maintenance and repair session.There are several modes: a world championship against increasingly tougher opponents, a multiplayer versus mode, a training mode, and a time trial where the time limit is the only foe.
