O-Zone

O-Zone is a Duel minigame in Mario Party 6. Its name is a pun on "." On the game's website, the minigame is named "Tic Tac Whoa!"

Introduction
If the player wants to get O's quickly, then it is vital for them to watch the introduction. It shows all the spaces uncovered, then covers them and spins them around on the platform they are on. The player does not have to watch each one spin around, because they go in a 360-degree turn.

Gameplay
To win this minigame, the player must ground-pound certain spaces that have O's under them. Once the player gets three of these out of five on the board, they win. If the space the player ground-pounds is an X, lightning bolts come down on the player and stun them for a few seconds. Some spaces do not have a letter under them at all; nothing happens if these spaces are pounded.
