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.
