Before you deposit a pound, read what the 31bets welcome bonus asks of you in return. A big headline figure means little if the wagering drags on for weeks, and a modest one can be easy to clear when the terms are fair. Treat the live promotions page at 31bets as final for current figures, since offers change.
The UKGC sets the rules for bonuses offered to UK customers. Since January 2026 it caps wagering at 10x, you must be 18 or over, and credit cards are banned for gambling deposits. That cap makes the 31bets welcome offer far easier to judge than the 40x and 50x deals you see on offshore sites.
Claiming follows the usual order for a new account:
The 31bets welcome code goes in at registration or at the deposit screen, depending on how the promotion is set up. If the box is empty and you forget to fill it, message live chat before you play a single spin. Many operators refuse to add a bonus once you have wagered real money.
These seven lines in the bonus terms decide whether the 31bets welcome bonus is worth taking:
| Condition | What to check |
|---|---|
| Eligibility | You are 18 or over, live in the UK and have no previous 31bets account. |
| Minimum deposit | The cashier shows the qualifying amount in pounds. Check it before you choose Pay by Phone, which limits deposits to small sums. |
| Wagering | UKGC rules cap it at 10x. A £50 bonus means £500 in total bets before you withdraw bonus winnings. |
| Expiry | Bonus funds and free spins carry a deadline. Find the number of days in the terms and set a reminder. |
| Game contribution | Slots tend to count in full. Table games and live casino often count for less, or not at all. |
| Maximum bet | A per-spin or per-bet limit applies while bonus funds are active. Exceeding it can void your winnings. |
| Payment methods | Some operators exclude certain e-wallets or phone-bill deposits from the offer. Confirm that your method qualifies. |
Do the sum before you accept. At 10x, a £20 bonus asks for £200 in bets, which a slot at 20p a spin delivers in 1,000 spins. If the terms list a higher multiplier than 10x, ask live chat why before you deposit.
Pick your games from the contribution list in the terms. Slots that count at 100% clear the requirement fastest, and a few hours on blackjack at 10% contribution can leave your wagering barely touched. Check the maximum bet too, because a single oversized stake can cost you the whole bonus.
The promotions page may list a separate 31bets sign up offer for sports and another for casino. You choose at registration, so pick the one that matches what you play. A casino bonus does nothing for you if you spend your evenings betting on football. Compare it with the 31bets new customer offer shown there as well, and weigh the wagering multiplier and the expiry date ahead of the headline amount.
Set a deposit limit in your account before you claim anything, and decide in advance how much you will spend. If a bonus pushes you to chase losses, stop and contact BeGambleAware, or register with GamStop to block all UK-licensed sites at once. Bonus funds are a small extra on top of your own money, and you can walk away from them at any point.
