Tube It or Lose It

Tube It or Lose It is a 1-vs-3 minigame found in Mario Party 5 and returns in Mario Party: The Top 100. The name is a pun off the phrase "Move it or lose it!"

Gameplay
The solo player controls a spiked machine while the three members of the team each control an inner tube, which is faster and more maneuverable than the spiked machine. As the players travel through the course, the solo player must collide with the team members, popping their inner tube and eliminating them. If the solo player can eliminate all three team members before the end of the course is reached, they win. If even one team member survives to the end, the team wins.

Along the way, rocks and tree stumps are encountered. The solo player can break these by colliding with them, but the team must maneuver around them. Also, jumps in the course can be used strategically by the players to avoid or hit the others.
