Slammer (minigame)

Slammer is a duel minigame found in Mario Party Advance. Its name comes from a slang term for prison.

Gameplay
The players attempt to wait patiently as both players have five lives. If a player uses a lever while the minigame picks a player to make a move, the player will instead be pounded by a hammer as the player loses a life. If the minigame picks the first player, the first player will either defend or hammer the second player. If the second player defends while the first player tries to attack, the hammer will bounce back to hit the first player. The player who defeated the other player wins.
