Unless a promotion explicitly states otherwise, all bonus funds are subject to a wagering requirement before any associated balance becomes eligible for withdrawal.

Failure to meet wagering requirements within the specified time will result in the automatic forfeiture of the bonus balance and any winnings derived from it.
