X-Y-Zap is a two player game in which the players are in co-operation rather than competition. Two joysticks are required in ports 1 and 2. Each player controls a tracker, one along the X-axis adjacent to the grid and the other along the Y-axis. The object of the game is for each player to line their tracker up with the spark which is moving inside the grid. When both players press their fire buttons together a neutralizer will appear at the intersection of each tracker's axis. If the spark is hit the score is increased and a new spark appears at the centre of the grid. A player cannot move his tracker whilst his fire button is pressed and should the spark hit a tracker a life will be lost.
