21Bit UK Welcome Bonus
Sign up at 21Bit and you can collect up to £350 in bonus funds plus 85 free spins across your first three deposits. The 21Bit welcome bonus matches 100% on deposit one, 50% on deposit two and 25% on deposit three, with 35x wagering on each tier.
Deposit tiers in the 21Bit casino welcome bonus
Your first three deposits each earn a different match. The 21Bit casino welcome bonus tops out at £350 and 85 free spins if you hit every cap.
| Deposit | Match | Max bonus | Free spins | Wagering |
|---|---|---|---|---|
| 1st deposit | 100% | £200 | 50 | 35x |
| 2nd deposit | 50% | £100 | 25 | 35x |
| 3rd deposit | 25% | £50 | 10 | 35x |
21Bit can change these figures, so confirm them on the site before you deposit. Each tier also carries a minimum deposit, which the cashier shows.
Deposit £200 and you receive £200 in bonus funds plus 50 free spins. At 35x, that £200 bonus means £7,000 in wagers before you can withdraw it. Read the terms to see whether the multiplier covers the bonus alone or the bonus plus your deposit, because the second reading doubles the work.
Claiming the 21Bit sign up offer in four steps
Register your account
Create an account with your email, date of birth and UK address. Expect a request for ID, so have a passport or driving licence ready before your first withdrawal.
Make your first deposit
Pay with a UK debit card (Visa or Mastercard), PayPal or an Open Banking transfer if the 21Bit cashier lists them. The UKGC banned credit cards for gambling in 2020, so a credit card will not work. Some operators also exclude e-wallets and Pay by Phone (Boku) from bonus offers, so check the 21Bit welcome offer terms before you pick a method.
Receive the bonus
21Bit credits the bonus funds and free spins once your deposit clears. Open your balance page and confirm both have arrived before you play.
Start playing
Spin eligible slots and watch your wagering counter. The 21Bit new customer offer carries a time limit, and any wagering left unfinished disappears with the bonus when the clock runs out.
Using a 21Bit welcome bonus code
Some promotions ask for a 21Bit welcome bonus code at registration or in the cashier. If you see a promo field, type the 21Bit welcome code in before you deposit. Skipping it can cost you the bonus, and support may refuse to add it later. Contact live chat if the field is missing and no bonus appears after your deposit clears.
Game contributions towards wagering
Slots count 100% towards the 35x requirement, so I would stick to them until the wagering clears. Other game types count for much less.
| Game type | Contribution | What it means for you |
|---|---|---|
| Slots | 100% | Fastest route through the wagering |
| Table games | 10% | Ten times the stakes for the same progress |
| Live casino | 10% | Playable, but slow for clearing a bonus |
| Game shows | 5% | Fun to watch, painful for wagering |
| Sports betting | Excluded in most terms | Sports promos run separately |
A £100 bonus at 35x means £3,500 in wagers. On slots, £3,500 of spins clears it. On live blackjack at 10%, you need £35,000 in stakes to reach the same point. Confirm the contribution rates in the bonus terms on the 21Bit site, since they can differ by game.
Staying in control with GamStop and BeGambleAware
UK-facing casinos need a UKGC licence, so look for the licence number in the 21Bit footer before you deposit. Set a deposit limit in your account on day one, and register with GamStop if you want a block across licensed operators. BeGambleAware lists free support if the play stops being fun. You must be 18 or over, and a bonus is never worth chasing losses for.
