Sink or Swim

Sink or Swim is a 1-vs.-3 minigame in Mario Party 6. Its name is a play on a phrase that describes a scenario where someone gets something right or fails, with no intermediate outcomes.

Introduction
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 positions.

Gameplay
The group players must avoid the mines that the solo player drops from above the pool they are in. The group players each have a breath meter; if they stay underwater too long, they 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 sink out of sight and are eliminated. The solo player wins by eliminating all the other players. The group players win if at least one of them survives long enough.
