Here you and a friend/ennemy can put an amount of money all together and battle, the winner gets the combination of both bets...

ex:i bet 2000 zeni so we both put 2000 zeni aside, we battle, and the winner gets 4000 zeni.

Each player gets 500 § for playing and the winners go on into a tournament later on, admission fee is 500 zeni. you cannot kill in the battle square!
