You won’t be able to collect your winnings until after you’ve met your bonus’ wagering requirements. This can take a while to do; however, you can claim your winnings once you’re finished. Casinos can transfer your winnings to you through your credit card, bank account, or through an eWallet service. Of the three methods, eWallet is the quickest way to do it.
There are also slot bonuses you can find that are ‘wager free’. However, finding no deposit bonuses that are also wager free might prove difficult to do.
