In-game description

Compat-I-Com is a Gaddget in Mario Party Advance. It is available from the beginning and has no requirements to unlock. The Gaddget can be used to play a two player minigame. Compat-I-Com is played on the same Game Boy Advance. Both players must press the two buttons on the left and right side. Once both players have pressed the buttons, a random percentage out of a 100 will be calculated. The percentage displayed is used to represent the compatibility between both players. A high score represents a good compatibility and a low score represents a bad compatibility.
