In 20XX, the world was filled with excitement for robot battles! Win the battles divided by class and get the belt! Win the most belts and make your gym famous!

Rocket Punch! is a trick-taking game where the timing to take the belt is important. On your turn, you play the robot cards in your hand, and the strongest robot wins the battle and gets the belt. The round ends when you run out of cards in your hand, and the gym that owns the belt at that point receives fame points. The player who reaches the specified number of Fame Points first is the winner.

The first edition of the game had a typo in the English language name of the game and the box says "Rocket Pounch".
