O-Zone

O-Zone is a Duel mini-game in Mario Party 6.

Gameplay
The whole point of the game is to beat the other player, as in all other Duel minigames. The way to win is to Ground Pound by pressing AA on certain spaces that have Os under them. Get three of these and you win. But if the space you Ground Pound on is an X, lightning bolts would come down on the player and he/she would be slightly shocked for a few seconds. Some spaces don't have a letter under it at all, this would not affect the gameplay.

Introduction
If you want to get Os really fast, then it is vital to watch th introduction. It shows all the spaces uncovered, then covers them and spins them around on the platform they're on. Watch 2, or 3 of the Os, the player doesn't have to watch each one spin around because they go a 360 turn, so the player could just stomp on the ones that he/she saw were Os.
