31Bet Casino Promo Codes 2026
31Bet Casino runs more bonus offers than most UK sites I have tested, and some need a code while others do not. I spent a week claiming each one, so the list below shows what you type, what you receive, and where the wagering catches you out.
You enter a 31Bet Casino promo code to claim the no deposit spins, the reload offers and the high roller match. The standard welcome package needs no code at all, which confused me on day one when I went looking for a box that did not exist.
31Bet Casino Promo Code UK: Active Bonus Codes (March 2026)
Make a first deposit of £15 or more and 31Bet Casino matches it 100% up to £150, then adds 100 free spins. You do not need a promo code for this offer.

How the Welcome Bonus Works
- Create your account if you have not already.
- Deposit at least £15 with a debit card, PayPal or Open Banking.
- You have 7 days to use the bonus.
- Wagering is 35x the bonus amount, so a £100 bonus means £3,500 in bets before you can withdraw.
- 31Bet Casino releases the 100 free spins on Gates of Olympus in batches of 50 per day.
- Winnings from the spins are capped at £50.
Second Deposit Bonus: 55% up to £150 + 50 Free Spins
Your second top-up earns a 55% match up to £150 and 50 more free spins. I deposited £50 and received £27.50 in bonus cash plus the spins.
What You Need to Know
- Deposit at least £15.
- The bonus stays valid for 7 days.
- Wagering is 35x the bonus amount.
- Claim or forfeit your first deposit bonus before you make this deposit.
Third Deposit Bonus: 100% up to £150
Your third deposit matches 100% up to £150, the same percentage as the first offer but without free spins. A £100 deposit gives you £200 to play with, and you wager the £100 bonus 35 times, which comes to £3,500.
Details
- Deposit at least £15.
- Use the bonus within 7 days.
- Wagering is 35x the bonus amount.
Get 20 Free Spins at 31Bet Casino with No Deposit
You can try 31Bet Casino without paying anything. Register with the code FREESPIN20 and 20 free spins land on Book of Dead. Mine arrived about two minutes after I confirmed my email address.
How to Get Your Free Spins
- Open the 31Bet Casino registration page and click Sign Up.
- Enter your email address and a password in the pop-up.
- Type FREESPIN20 into the Promo Code box.
- Complete sign-up and confirm your email address.
- Fill in your personal details when the second pop-up opens.
You wager any winnings from these spins 40 times before you can withdraw them. Winning £5 means £200 in bets, so treat this offer as a free test drive of the site and expect little cash from it.
31Bet Casino Promo Code for High Rollers
Large deposits earn their own match at 31Bet Casino, and you claim it with a code.
Highroller Bonus: 50% up to £500
- Deposit at least £300 to qualify.
- Enter HIGHROLL50 in the promo code field on the deposit form.
- Use the bonus within 7 days.
- Wagering is 35x the bonus amount.
A £1,000 deposit earns the full £500, and your wagering target then reaches £17,500. Do that sum before you deposit.
31Bet Casino Promo Codes and Sports Betting
The sportsbook has its own offers, separate from the casino bonuses, so you can claim both. Sports bonuses sit in a different balance from your casino funds.
Sports Second Deposit Bonus: 75% up to £150
- Make your second sports deposit to receive a 75% bonus up to £150.
- Deposit at least £15.
- You have 14 days to use the bonus.
- Wagering is 5x, with minimum odds of 1.80 per selection.
A £100 bonus needs £500 in qualifying bets. That is far lighter than the 35x on casino offers.
Sports Third Deposit Bonus: 50% up to £200
- Your third sports deposit earns a 50% bonus up to £200.
- Deposit at least £15.
- You have 14 days to use it.
- Wagering is 5x.
Football, tennis and cricket bets all count towards the requirement.
Using a 31Bet Casino Promo Code
- Log in to your 31Bet Casino account or complete registration.
- Open the Cashier and choose Deposit.
- Select your payment method and enter the amount.
- Find the Promo Code or Bonus Code field on the deposit form.
- Type the code in capitals, because codes are case-sensitive.
- Complete the deposit. The bonus appears in your account within a minute or two.
- Contact live chat if the bonus does not show up.
31Bet Casino Promo Code for Existing Customers
Loyal accounts get codes too. 31Bet Casino sends reload codes by email, app notification and social media, and cashback codes arrive every week for active accounts. The VIP programme adds personalised codes with larger percentages.
A 31Bet Casino promo code for existing customers rarely stays live beyond a week, so check your inbox before you deposit. We verify the codes on this page every week and remove any that have expired.
Ongoing 31Bet Casino Promotions and Extra Bonuses
The welcome package is only the start of the offers. Once you have an account, you find several recurring promotions.
ComboBoost for Sports Betting
Accumulator bettors earn extra winnings with ComboBoost.
- Bet on at least 10 matches to earn up to 1.5x extra.
- At least 4 selections need odds of 1.30 or higher.
Cashback Every Week: Up to 25%
31Bet Casino returns up to 25% of your net losses every week. It covers slots, table games and live casino.
Rakeback: Up to 17%
Rakeback climbs as you rise through the VIP levels, topping out at 17%. Higher levels return more of your stakes.
Tournaments
31Bet Casino runs tournaments for slots and live casino games. Prize pools change each time, so check the promotions page before you play.
Missions and Coins
Missions pay out coins when you complete tasks such as betting on esports or playing set games.
- Spend coins in the 31Bet Casino store on rewards.
- Missions also push you up the VIP levels faster.

- Cash Wheel
- Free Spins Wheel
- Coins Wheel
I landed 10 free spins on my first go at the Free Spins Wheel.

Quick Tips for Your 31Bet Casino Promo Codes
Three habits saved me from losing bonuses:
- Watch the clock: Every bonus has a time limit, and the wagering must finish inside it.
- Read the game rules: Slots contribute 100% towards wagering, while roulette and blackjack contribute 10%. Casino and sportsbook bonuses follow different terms.
- Type codes in capitals: HIGHROLL50 works. Highroll50 does not.
Cash Out Your 31Bet Casino Bonuses
You need a real-money deposit for every bonus except the no deposit spins. UK methods cover most needs.
Deposit Methods at 31Bet Casino
- Visa and Mastercard debit cards: Minimum £15, maximum £4,000. Deposits post immediately.
- PayPal: Minimum £15, maximum £4,000.
- Open Banking / Faster Payments: Minimum £15, maximum £4,000.
- Skrill: Same £15 to £4,000 range.
- Pay by Phone (Boku): Capped at £30 per transaction, so it will not cover a bonus deposit above that.
31Bet Casino does not accept credit cards, because UK rules ban them for gambling deposits.
Withdrawal Options and Limits
You can request a withdrawal once you finish the wagering. 31Bet Casino asks for ID before your first payout, so upload your documents early. My £80 PayPal withdrawal cleared in about six hours after verification, and Faster Payments transfers take up to two business days.
- Up to £2,000 per day
- Up to £5,000 per week
- Up to £15,000 per month
You withdraw through the same method you used to deposit. Pay by Phone cannot receive withdrawals, so you need a second method such as PayPal or your bank.
