Sink or Swim
Sink or Swim is a 1-vs-3 minigame in the game, Mario Party 6.
Gameplay
The whole point of the game for the 3 players is avoid the mines that the solo player drops from above the pool in which they are swimming underwater. The 3 players have a life meter, if they stay underwater to long, they will float to the top to get air, making it easier for the solo player to drop mines on them. Whenever the solo player drops a mine on one of the other players, they will sink. When the 1 player drops mines on all the other players, the solo player would win. But if the 3 players survive long enough, they would win.
Introduction
