21 Casino Bonuses
121% welcome bonus up to £100 + 10 free spins on Book of Dead
Last verified: March 2026 | Operator: LeoVegas Gaming PLC | UKGC Licence: 39198
Most UK casinos offer a flat 100% match on your first deposit. 21 Casino goes a bit further with 121% — the extra 21% is a nod to the brand name. Put in £10 and you get £12.10 in bonus funds on top, so you're playing with £22.10 total. The cap is £100 in bonus money, which you'd hit with a deposit of about £82.64.
There's also 10 free spins on Book of Dead waiting after you register — no deposit needed. Winnings from those spins only need 10x wagering, which is much better than the 35x on the deposit bonus itself.
We've put together the exact wagering maths, a comparison with other UK casinos, and the key terms you should know about. All numbers were checked against 21 Casino's promotions page in March 2026.

Welcome Bonus: 121% up to £100

How 21 Casino Compares
To put the 21 Casino bonus in context, here's how it sits next to other UKGC-licensed casinos:
| Casino | Match % | Max Bonus | Wagering | Min Deposit |
|---|---|---|---|---|
| 21 Casino | 121% | £100 | 35x | £10 |
| Industry Average | 100% | £100–£200 | 35–40x | £10–£20 |
| Low Wagering Leaders | 100% | £50–£100 | 0–10x | £10 |
| High Bonus Leaders | 100–200% | £300–£500 | 40–65x | £20 |
The 121% match beats the usual 100%, but the £100 cap is on the low side. 35x wagering is about average. Where 21 Casino does well is the no-deposit spins — 10x wagering is hard to find elsewhere.
Bonus Wagering Explained
The 35x applies to your bonus amount only — not your deposit. So if you get a £50 bonus, you need to wager £1,750 (£50 × 35) before you can withdraw any bonus winnings. Slots usually count 100% towards that target, but table games often count less. Check the full terms on 21 Casino's site for current contribution rates.
To deposit and activate your bonus, you can use any accepted payment method. The minimum qualifying deposit is £10. Ready to get started? Create your account and choose from 1,200+ games to play with your bonus funds.
