Craps is an excluded game and therefore you violated the terms and conditions of the bonus.

Don't be surprised if they cancel the withdrawal and remove the money from your account.

Following all of the rules for each bonus is extremely important if you'd like to take full advantage of them and get your winnings without having to deposit.

They may let it slide, but more often than not if you play an excluded game you will not be eligible to cashout from the bonus.
