History
Mario Tennis series
Mario Power Tennis
Wario Factory Court is one of the default boards in Mario Power Tennis. It is somewhat based on Wario's WarioWare factory - judging by the picture of him in his WarioWare suit in the background. In normal mode, it is set on a group of conveyor belts that don't move. In the gimmick version of this court, the net has many across up and down-facing arrows. If someone hits it when hitting the ball, whichever direction is hit will be the direction the conveyor belt, on which the players stands on, moves. Bob-omb's can be seen watching the game, and they will explode when someone gets a point. Wario Factory Court is also the setting for the Special Game Chain-Chomp Challenge, which also involved the conveyor belts as a gimmick.
Mario Hoops 3-on-3
Wario Factory is the first playable court in the Star Tourney of Mario Hoops 3-on-3.
Wario Factory is a basketball court set in a gold factory. The court perpetually moves up and down similar to an elevator. However, this has no effect on gameplay. However, when the court stops moving, two hatches on each side of the court open and Bob-ombs start walking out. These can be picked up and thrown by either team to make them explode. The explosions are bigger than those of normal bombs.
