Button Mashers

Button Mashers is a Duel minigame found in Mario Party 5. It returns in Mario Party: The Top 100.

Gameplay
Players try to avoid getting crushed by the blocks falling from the sky.

To do so, they must quickly and simultaneously press every button shown on each of the blocks they are carrying. If both players survive for a few seconds, another block will fall, requiring the players to press two buttons simultaneously. If both still survive, another block will fall, making a total of three, then four, five, and finally six. After that, the player who stops pressing the buttons gets crushed.

Ending
If at anytime a player fails to press his or her button(s) quickly enough during the game, then that character gets crushed, making the opponent win the game. However, if both players get crushed at the same time, then the minigame ends in a draw.
