Bakugan is simple. First, when each player is ready, shout "Field- Open!" Easy enough. Then, what you do is you and your opponent put down one of your heavier Bakugan cards, your Gate Card, and say "Gate card- Set!" After that, the youngest player goes 1st, and shoots, trying to hit his card, a Bakugan. Then, the opponent does the same. You can throw down an ability card, which you followthe instructions on the card, or attack. When you attack, you look on the opponents G power and if yours is higher, you can get the opposing Bakugan out of play. If you think your Bakugan's G power is too low, you can build its G power with a regular ability card, in which you just follow the instructions, or you can use a character card which doubles your Bakugan's G power if the picture on the card is the same as your Bakugan. Once you have beaten the opponents Bakugan you get their Gate Card. Once you get three Bakugan Gate cards, you win.
NOTE: You can only have three Bakugan, three ability cards, and three gate cards that you battle with. Carry around as many as you want, but battle with only three.
I hope this helps and makes you a good brawler.
