Everyone starts off with 10,000 ChampCash in a tournament.
That ChampCash is specific to that tournament and is used to rank you amongst others, who also start with 10,000 ChampCash.
Use your ChampCash to place bets, in order to grow the amount you have and move up the rankings.
Your ChampCash doesn't roll over and is linked to that tournament only!
Run out of ChampCash?
No worries mate, just re-buy to top up. You just have to have a balance lower than the minimum bet (250 in Racing and 500 in Sports) and have no pending bets!
