There are 14 different League tiers, from Novice to Legendary.
Beat other players and win Cash from the Bank Roll to move up within your current League. (Cash from Piggy Banks and Free Rolls doesn't count).
At the end of the week you win prizes based on where you came. If you come high enough you may even be promoted to a higher league. But, if you come low down, or don't play for a week, you'll be demoted to a lower League.
Can you make it all the way to the top of the Legendary League and win the ultimate prize?
