Frequently Asked Questions

1. What are wagering requirements in casino bonuses?

Wagering requirements refer to the number of times you need to bet the bonus money before you can withdraw any winnings made from it. For instance, if you receive a £100 bonus with a 30x wagering requirement, you need to bet £3000 before you can withdraw winnings from the bonus money.

2. Are sign-up bonuses only for new players?

Yes, sign-up bonuses are typically offered to attract new players. However, online casinos also offer various promotions and bonuses for existing players, such as reload bonuses, loyalty bonuses, and more.

3. Can I withdraw my bonus immediately?

No, you can’t. Bonuses are usually subject to wagering requirements, which must be met before any winnings can be withdrawn. Some casinos may also have a time limit within which the bonus must be used.

4. Is it necessary to claim a sign-up bonus?

No, it’s not. While sign-up bonuses can boost your initial bankroll, they come with terms and conditions that may not suit every player. Always read the fine print before deciding whether to claim a bonus.
