Key takeaways
- Casumo matches 50% of your first deposit up to £100; you need to deposit £200 for the full £100.
- 10Bet matches 100% up to £25 on slots, so a £25 deposit gets the full bonus.
- Both carry 10x wagering on the bonus: £1,000 of play for Casumo's maximum, £250 for 10Bet's.
- Deadlines are tight: 7 days at Casumo, 3 days to wager at 10Bet.
How a deposit match works
A deposit bonus adds a percentage of your first deposit as bonus funds, up to a maximum. A 100% match on a £25 deposit adds £25 of bonus; a 50% match on £200 adds £100. Bonus funds are separate from your cash, and they come with wagering: you need to place bets worth a multiple of the bonus before any winnings from it can be withdrawn.
Since 19 January 2026, that multiple can't be more than 10 for a UK-licensed casino. Both offers on this page use the full 10x.

Is a deposit bonus worth it?
A deposit bonus is worth it when you were going to deposit and play that amount anyway. It extends your play, and the 10x cap makes it realistic to complete. It's less useful if you'd only deposit to chase the bonus, or if the deadline is shorter than your normal playing pattern. If you'd rather keep everything you win from the start, compare no wagering offers. To test your own numbers, use the wagering calculator.
Terms to watch on deposit bonuses
- Opt-in. Casumo needs you to opt in before depositing; 10Bet needs you to select the bonus at sign-up.
- Game contribution. Slots usually count in full; table games may count less or not at all.
- Maximum bet. Casinos can set a lower stake limit while a bonus is active.
- Withdrawing early. Withdrawing before you finish wagering normally forfeits the bonus and its winnings.
How we check every offer
We read each casino's own promotion page and full terms, then record the qualifying stake, spin value, eligible games, deadlines and wagering. We confirm the operator's licence on the UK Gambling Commission register, and we recheck every offer at least once a month and whenever a casino changes it. If a detail can't be confirmed, we leave it out or tell you to check the casino's terms rather than guess. Read the full method on our how we rate page.
Play within your limits
A bonus is a way to try a casino, not a way to make money. Set a deposit limit when you're prompted before your first deposit, and don't deposit more than you'd planned just to unlock a bigger bonus. If you want to talk to someone, the National Gambling Helpline is free on 0808 8020 133. More help is on our responsible gambling page.
Frequently asked questions
What is the best first deposit bonus in the UK?
Casumo has the bigger maximum at £100, but needs a £200 deposit to reach it. 10Bet's 100% up to £25 gives more bonus per pound for smaller deposits.
How do I work out wagering on a deposit bonus?
Multiply the bonus amount by the wagering requirement. A £25 bonus at 10x needs £250 of bets.
Is wagering on the deposit or the bonus?
On both offers here, wagering applies to the bonus amount only.
Can wagering be more than 10x?
Not at a UK-licensed casino since 19 January 2026.
