Things You Should Know About Casino 400 Bonus UK Offers

  • Make sure that there is no cashout limit or it is high enough. This means you are allowed to withdraw only a certain amount, no matter how much you have won. For example, if the maximum cashout limit is 250 GBP and your bonus is 1.000 GBP, you won’t be able to withdraw more than 250 GBP. The rest of your bonus will be void.
  • Make sure the maximum wager limit is high enough. Until the wagering requirement is complete, you will have a maximum wager limit – usually 5 GBP. It should not be lower than this amount. Otherwise, it will take too long to complete the requirement.
  • Make sure the wagering rate is low enough. Ideally, the wagering rate should not be higher than 40x, and it should be as low as possible. If this rate is higher than 40, it may be impossible to complete the wagering.
