How to Withdraw Bonus Money

Bonus money comes with terms and conditions and wagering requirements that must be met before you can cashout your winnings. Below are our top tips on how to ensure you get a withdrawal.

  • Read The Terms and Conditions: This is the most important advice we can give you. It might seem tedious, but it is important and there are particular areas to pay attention to.
  • Wagering Requirements: What is the wagering requirement attached to your bonus? All bonuses have them and a no deposit slot bonus will have higher wagering requirements than deposit bonuses. This tells you how much you have to bet in order to clear the bonus and cashout your winnings. For example, a $10 no deposit bonus with wagering requirements of 50x means you have to playthrough $500 to clear your bonus and cashout your winnings.
  • How Long do you have to clear your bonus? Bonuses expire so you need to check how long you have to meet the playthrough. Sometimes you will have 7 days, sometimes a month, sometimes 24 hours. If you don't meet the wagering requirements within the time frame, you lose your bonus money. The longer the expiry period the more chance you have of cashing out.
  • What Games Can I play? If you've claimed a no deposit slots bonus, be sure to check if it's tied to a specific title or a selection of games. Check also the bet size and the contribution percentage. Most slots contribute 100% towards wagering requirements, but there may be games that are not permitted such as progressive jackpots.
