Sink or Swim
Sink or Swim is a 1-vs.-3 minigame in the game Mario Party 6. Its name is a play on the phrase "sink or swim," which describes a scenario where someone gets something right or fails, with no intermediate outcomes.
The introduction shows the solo player trying to drop a mine on the group player in the middle of the pond and missing, after which they take their default position.
The group players must avoid the mines that the solo player drops from above the pool they are in. The three players each have a breath meter; if they stay underwater too long, they will float to the top to get air, making it easier for the solo player to drop mines on them. Any group players hit by mines will be eliminated and sink out of sight. The solo player wins by eliminating all the other players; the group players win if at least one of them survives long enough.
Solo (1 player)
