Tidal Toss

Tidal Toss is a 1-vs-3 minigame found in Mario Party 3 and Mario Party: The Top 100.

Gameplay
Three players try to stay on the platform while the solo player attempts to knock them off by either jumping on or Ground Pounding the boat and making waves, with their size being dependent on the force of the jump/Ground Pound. If one of the three players gets knocked off the platform, they are eliminated from the minigame.

If the player on the boat knocks off all three of the other players, that player wins. However, if at least a single member of the three player team survives when time runs out, the team wins.
