Three deposits unlock the full Gratowin welcome bonus: up to £300 in matched funds and 150 free spins, with 10x wagering on the bonus. Each part needs a minimum deposit of £20, so £60 gets you all the spins.
For years UK casinos hung 35x or 40x on offers like this. The UK Gambling Commission capped bonus wagering at 10x from January 2026, so every UKGC-licensed rival now uses the same multiplier. That leaves the match percentage, the spin count and the time limit as the points that separate one offer from another.
The Gratowin casino welcome bonus splits into three matched deposits, each with 50 free spins attached. Spreading it out suits you if you plan to play over a few weeks. If you want one big session, the first deposit gives you the best match rate.
Gratowin Welcome Offer: The Three-Deposit Structure
The Gratowin welcome offer matches 100% of your first deposit up to £100, then 50% of your second and third deposits up to £100 each. Every deposit adds 50 free spins.
| Deposit | Match | Max bonus | Free spins | Min deposit | Wagering |
| 1st | 100% | £100 | 50 | £20 | 10x |
| 2nd | 50% | £100 | 50 | £20 | 10x |
| 3rd | 50% | £100 | 50 | £20 | 10x |
| Total | n/a | £300 | 150 | £60 | 10x each |
Depositing £20 three times gets you all 150 spins but only £40 in bonus funds (£20, £10 and £10). The full £300 takes £500 in deposits: £100, then £200 and £200.
First Deposit: 100% Up to £100 and 50 Free Spins
Put in £100 and Gratowin adds £100, so you start with £200 and 50 spins at £0.10 each. The 100% rate beats anything on deposits two and three, which makes the first payment the best value per pound. Set the amount from your budget and ignore the cap. A £20 deposit still earns a £20 match.
Second and Third Deposits: 50% Up to £100 Each
A £200 deposit earns a £100 bonus and 50 more spins. Most UK casinos block a second bonus while one is live, so finish the current wagering before you deposit again.
Claiming the Gratowin Sign Up Offer in Five Steps
The sign up offer takes about ten minutes from registration to bonus balance if your documents are ready.
- Register at Gratowin with your real name, date of birth, postcode and email address. You must be 18 or over, and the details must match your ID.
- Click the confirmation link in the email Gratowin sends you.
- Upload your photo ID and proof of address before you deposit. UKGC rules require Gratowin to verify your name, address and date of birth before you gamble, and early checks spare you a delay when you withdraw.
- Open the cashier and pick a payment method: a Visa or Mastercard debit card, PayPal, an Open Banking bank transfer through Faster Payments, or Pay by Phone. Deposit at least £20.
- Enter your code or tick the opt-in box, then confirm the payment. The bonus funds and 50 free spins appear in your account.
The UKGC banned credit cards for gambling in April 2020, so a credit card will fail at the cashier. Some casinos exclude PayPal or other e-wallets from bonus deposits, so read the excluded methods in the bonus terms before you pay.
Gratowin Welcome Bonus Code and Welcome Code
A Gratowin welcome bonus code goes in the box on the deposit screen. Some offers credit through a tickbox with no code at all, and you see one version or the other in the cashier.
Look up the current Gratowin welcome code on the promotions page before you deposit. Casinos rarely credit a missed bonus after the payment clears. Live chat sometimes fixes it, but you cannot count on that.
Wagering, Free Spins and Time Limits
The Gratowin new customer offer carries 10x wagering on bonus funds. A £100 bonus needs £1,000 in bets before you can withdraw winnings from it. Your own deposit sits outside that requirement.
Slots count at 100%. Roulette, blackjack and live tables count for a fraction, and some jackpot slots count for nothing. The bonus terms list every contribution rate, so read that table before you pick a game.
You have 7 days from the credit to finish. At £1 a spin, £1,000 of wagering is 1,000 spins, which fits into a few evenings. Bonus terms cap your stake per spin while the bonus is live, and breaking that cap voids your winnings, so check the figure before you raise your bet.
Free Spins: What 50 Spins Are Worth
Fifty spins at £0.10 add up to £5 of play. At a 96% RTP you can expect about £4.80 back, and 10x wagering on that is £48. Treat the spins as a small extra. Play them the day they arrive, since unused spins expire under most UK terms.
Is the Gratowin Welcome Bonus Worth Claiming?
I like the 10x requirement. Old-style offers asked for £4,500 in bets on a £150 bonus, and £1,000 on a £100 bonus is a different proposition. The three-part structure also lets you stop after one deposit if the games disappoint you.
The weak spot is the 50% rate on deposits two and three. A £200 deposit for £100 extra gives you half the first deposit's value. I would play out the first bonus, see how Gratowin's slots suit you, and then decide on part two.
Slots fans who stick to a fixed budget get the most from this offer. If you prefer live blackjack or roulette, the low contribution rates make the wagering slow, and you might skip the bonus altogether.
Play Safely With Any Bonus
A bonus keeps you betting until you meet the wagering, so set a deposit limit in your account before you claim. If the play stops being fun, GamStop blocks every UKGC-licensed site in one registration. BeGambleAware offers free advice, and the National Gambling Helpline on 0808 8020 133 runs 24 hours a day.
