Concentration © 1981 Gordon, Al.
This is a two player game. After a brief introduction setting the mood, there is a short pause while the computer shuffles the cards and lays them out. Use the joystick JX and JY to position the indicator and the card you wish to reveal-- pull trigger. Repeat for a different card. If the cards match, they will disappear from the screen; same player has another turn. If no match, play shifted to joystick #2. Scores kept secret and displayed after all cards have been paired.
Unpublished Arcadian submission.
