There is no specific sum or percentage that we can tell you right away. The money left depends on the casino you played, the no bonus conditions you got, and the specific wagering requirements imposed on the bonus used. To get the best no deposit bonus online casino, we recommend searching through our list of available casinos. Here you will be able to find the most fair venues to keep the bigger part of your winnings.
Whenever you need to calculate what will be left of your winnings, read the regulations of the no deposit bonus in the selected casino (the info would be either on the Terms & Conditions page or on the Bonuses page).Then, after winning, just take a calculator and see how much of the won money you will need to spend and how much you can leave to withdraw. Remember also about the different wagering percentage each casino game can offer.
