"Bakugan: Torneio dos Mundos" is a contest to see which player can win more tournaments in the 6 worlds of "Bakugan Battle Brawlers". Each round, a world is randomly chosen. Players then select one Bakugan card from their hands, and then one "special effects" card. All variables are added up and the owner of the most powerful Bakugan places a token on the world where the tournament was played. The first player to achieve a number of victories wins the game (text by the game's designer).
