Bound of Music

Bound of Music is a duel mini-game found in Mario Party 5.

Gameplay
Players attempt to find hidden ♩ Blocks by jumping and punching them. However, the blocks are invisible, so players must jump around until they hit one, at which point it will become solid for a second, indicating it has been hit. Additionally, Brick Blocks which have no value are hidden among the ♩ blocks; hitting one accomplishes nothing. The blocks will periodically glisten every five seconds, giving the players a general idea of where they are.

At the end of fifteen seconds, or when all blocks have been hit, the player with more ♩ Blocks hit wins.

Controls
Control Stick – Move A button – Jump

Trivia
