Lights Out is a 1 vs. 3 Mini-game in Mario Party 2.
Gameplay
One player wields a mallet while the other three hold bright lightbulbs. The player with the mallet must hit the other three players with the mallet. However, the lights flicker on and off in the minigame's room.
The one player wins if he or she hits each player with the mallet. The other three players win if at least one survives the time limit.
