The more win the greater and you will need to be wagered out a total of bets before you get your bonus money out. This is true for betting bonuses, but usually the wagering must be done in order to get your winnings (since the casino needs to protect itself from the hoards of hungry masses... ) When you get a $10% bonus, the rules state that you must wager a minimum of $20. Before you get the bonus money ($10), you must invest a total of $20 in your chosen sports for 20 straight bets of $10 each.
