The rules for the big game are almost identical to a regular game. The differences are that you need 6 bakugan, 6 gate cards ( 2 of each color ) and 6 ability cards ( 2 of each color ) instead of 3 each as in the normal game. You cannot have any exact copies of bakugan on your "team" and you cannot have more than one of any specific gate or ability card. To win in a Big Game, you must get 6 gate cards into your used pile.
