Spinfin credited my first batch of free spins within two minutes of a £20 Visa debit deposit. The wagering terms took me longer to read than the deposit took to clear.
Each Spinfin promo code on this page comes with its own deadline, wagering requirement and eligibility rule. I have claimed the welcome offer, the no deposit spins and a reload bonus myself, and I recheck every code once a week. A few offers are free to claim, and the welcome package needs no code at all.
Spinfin Promo Code UK: Active Bonus Codes (March 2026)
Your first deposit earns a 100% match up to £150 plus 100 free spins. Spinfin credits it as soon as a deposit of £20 or more lands, so leave the code box empty.

Welcome Bonus Terms
- Create your account if you have not already.
- Deposit at least £20 with a Visa or Mastercard debit card, PayPal or Open Banking.
- You have 7 days to use the bonus.
- The wagering requirement is 35x the bonus amount, so a full £150 bonus means £5,250 in bets.
- Spinfin releases the 100 free spins on Gates of Olympus in batches of 20 per day over five days.
- You can win up to £50 from the free spins.
Log in every day to collect each batch. I skipped day three and lost 20 spins, which at 20p a spin cost me £4 in stakes.
Second Deposit Bonus: 55% up to £150 + 100 Free Spins
Your second deposit earns a 55% match up to £150 and 100 more free spins. They land on Gates of Olympus again, in the same batches of 20 per day.
Terms to Check Before You Deposit
- Deposit at least £20.
- The bonus expires after 7 days.
- The wagering requirement is 35x.
- You must have claimed the welcome bonus first.
I put in £50 and received £27.50 in bonus funds, which meant £962.50 of wagering. The extra spins gave me another five days of play on a small stake.
Third Deposit Bonus: 100% up to £150
The third deposit matches 100% up to £150, the same as your first, with no free spins attached.
Details
- Deposit at least £20.
- Use the bonus within 7 days.
- The wagering requirement is 35x.
Deposit £100 and you hold £200 to play with. The 35x requirement on the £100 bonus means £3,500 in bets before you can withdraw it.
Get 20 Free Spins at Spinfin with No Deposit
You can try Spinfin without spending anything. Sign up with the right code and the casino hands you 20 free spins on Book of Cats.
Claiming Your Free Spins
- Open the Spinfin registration page and click Sign Up.
- Enter your email address and a password in the pop-up.
- Type BOOKCATS20 in the Promo Code box.
- Submit the form.
- Click the confirmation link in your email.
- Fill in your personal details in the second pop-up.
- Open Book of Cats to find your 20 spins waiting.
You must wager your winnings 40 times before you can withdraw. My 20 spins returned £3.40, which left me with £136 of wagering on a few pounds. Treat these spins as a free trial of the site.
Spinfin Promo Code for High Rollers
Large deposits unlock their own offer. Enter the promo code at the cashier when you deposit £300 or more.
High Roller Bonus: 50% up to £500
- Deposit at least £300 to qualify.
- Enter HIGHROLLER in the cashier.
- Use the bonus within 7 days.
- The wagering requirement is 35x.
A £1,000 deposit earns the full £500 bonus, and 35x on that bonus equals £17,500 in bets. Compare that figure with your bankroll before you commit.
Spinfin Casino Promo Codes and Sports Betting
The sportsbook runs its own offers, separate from the casino bonuses, so you can claim both.
Sports Second Deposit Bonus: 75% up to £150
- Make your second sports deposit of at least £20.
- You have 14 days to use the bonus.
- The wagering requirement is 5x.
- Qualifying bets need minimum odds of 1.50.
Sports Third Deposit Bonus: 50% up to £200
- Make your third sports deposit of at least £20.
- You have 14 days to use the bonus.
- The wagering requirement is 5x.
A 5x requirement is the lowest on the site. A £100 sports bonus needs £500 in bets, which I cleared across a weekend of Premier League singles.
Entering a Spinfin Casino Promo Code at the Cashier
- Log in to your Spinfin account or finish registration.
- Open the Cashier and choose Deposit.
- Select your payment method and enter the amount.
- Find the Promo Code field on the deposit form.
- Type the code in capitals as shown. Codes are case-sensitive.
- Complete the deposit and check your bonus balance.
- Contact live chat if the bonus is missing. Support restored mine within ten minutes when I mistyped a code.
Spinfin Promo Code for Existing Customers
The Spinfin promo code existing customers see most often is RELOAD50, a 50% match up to £100. Reload codes arrive by email, in-app message and Spinfin's social channels. Mine landed on a Thursday and expired on Sunday night, with 35x wagering and a 7 day limit.
Cashback codes reach active accounts every week, and VIP members receive personalised codes with larger matches. Miss the window on any of them and the code lapses, so check your inbox before you log out. I verify the codes on this page every week.
Ongoing Spinfin Promotions and Extra Bonuses
A Spinfin promotional code covers more than the welcome package. Once you join, you find a rotating set of offers.
ComboBoost for Sports Betting
Place an accumulator with at least 10 selections to earn up to 1.5x extra on your winnings. Three selections need odds of 1.30 or higher.
Weekly Cashback: Up to 20%
Spinfin returns up to 20% of your net losses every week on slots and table games. Live casino play does not count, which I found out after a losing Sunday at the roulette tables.
Rakeback: Up to 17%
Rakeback rises with your VIP level and tops out at 17%. You earn it back on every bet, so the higher your tier, the bigger the return.
Tournaments
Spinfin runs slot and live casino tournaments with a different prize pool each time. Check the promotions page before you start a session.
Missions and Coins
Missions ask you to play specific games or place certain bets on the app, and each one pays out coins.
- Spend coins in the Spinfin store on rewards.
- Missions also lift your VIP level faster.
Spin the Wheel
Four mini-game wheels hand out prizes:
- Cash Wheel
- Free Spins Wheel
- Coins Wheel
- Seasonal Wheel
My best spin on the Free Spins Wheel returned 15 spins, and the Cash Wheel paid me £2.
Spinfin Promo Code VIP: Earn More Rewards
You join the VIP programme automatically when you register and play for real money. Every £25 wagered earns 1 point, and more points lift your rank.
VIP Levels
- Bronze (starting level)
- Silver
- Gold
- Platinum
VIP Benefits
- Higher cashback rates
- Monthly rakeback
- Weekly reload bonuses
- Special events and gifts
Silver took me about three weeks at £30 a day, so expect a slow climb.
Quick Tips for Using Your Spinfin Promo Codes
- Watch the clock. Every bonus has a deadline. Casino bonuses last 7 days and sportsbook bonuses last 14.
- Read the game rules. Slots count 100% towards wagering, and table games count far less. Casino and sportsbook bonuses follow separate rules.
- Enter codes at the right step. BOOKCATS20 goes in at registration and HIGHROLLER goes in at the cashier.
- Finish one bonus before you start another. Spinfin locks your balance to the active bonus until you clear it.
Cash Out Your Spinfin Bonuses
Every bonus except the no deposit spins needs a real money deposit first.
Deposit Methods at Spinfin
- Visa and Mastercard debit cards: £20 minimum, £5,000 maximum. Deposits post straight away.
- PayPal: £20 minimum, £4,000 maximum. My deposit cleared in seconds.
- Open Banking (Faster Payments): £20 minimum, £5,000 maximum, with funds arriving the same minute.
- Pay by Phone: £10 minimum, £30 maximum per day. You cannot withdraw to it.
- Skrill: £20 minimum, £4,000 maximum. Skrill deposits do not qualify for bonuses.
You cannot use a credit card to deposit, because UK rules ban credit cards for gambling.
Withdrawal Options and Limits
Clear your wagering first, then request a withdrawal. Spinfin sets these limits:
- Up to £2,000 per day
- Up to £5,000 per week
- Up to £15,000 per month
You withdraw to the same method you deposited with. PayPal and Skrill payouts reached me within 24 hours, and debit card payouts took up to three business days.
