From the Super Mario Wiki
The game starts with Wario's face with random face parts. To win, the players have to remake the starting face. To do so, they have to tap face parts needed to remake it. If done so, the game is won. However, if the face that the players made doesn't match the starting one or if time's up and the face is still not ready, they'll lose the game.
