 for example is a league link. To join the league you open the page and at the top left hand side you will see a "free sign up" link. Click that and follow the steps. Click as many free bux boxes as possible as this helps you enter into some tournaments. (The bux remain fake) To enter a tournament, simply go to the leagues league room. In this case, Allstarz play in 8ball league room 1. Tournaments are usually run quite daily and everyone is welcome to join a fun league.
