This game is about the same style as the Bomberman Series. The principal game functions are that you, as either Wario or Bomberman walk around on a level and try to blow up your opponent.
By blowing up blocks that are blocking your way you can uncover power-ups, that can give you three abilities:
1) The bombs get a longer blast.
2) You can place more bombs at once.
3) You get invulnerable but are also unable to place bombs.
Every power-up except for the third one works during the entire round and can be increased by picking up more power-ups of the same type.
In the single-player game, you fight as Wario against different amounts of Bombermen, and at the forth course of every "world" you face a boss.
In multiplayer, you play as either Wario or Bomberman, and try to blow up your friend / enemy.
