You can claim 100% up to £150 plus 100 free spins at BigWins, and that welcome offer needs no BigWins promo code. Four other offers do need one: 20 no deposit spins, a high roller match, a weekly reload and monthly cashback. Each carries its own wagering requirement and deadline.

Welcome Bonus: 100% up to £150 + 100 Free Spins
Deposit £10 or more and BigWins matches it 100% up to £150. BigWins adds 100 free spins on Gates of Olympus and releases them as 20 spins a day over five days. Log in each day to collect that day's batch.
The bonus stays valid for 7 days and carries 35x wagering on the bonus amount. A £100 bonus means you stake £3,500 before you can withdraw it. Free spin winnings cap at £50.
Second and Third Deposit Bonuses
Your second deposit earns 55% up to £150 plus another 100 free spins. Your third deposit earns 100% up to £150 with no spins attached. Both need a £10 minimum, both expire after 7 days and both carry 35x wagering. Claim the welcome bonus first, because the second deposit offer stays locked until you do.
BigWins Promotional Code for 20 No Deposit Free Spins
A BigWins promotional code is a short string of letters and numbers you type into a box at sign-up or in the cashier. FREESPIN20 gives you 20 spins on Book of Cats without a deposit. Follow these steps to claim them:
- Open the BigWins site and click Sign Up.
- Enter your email address and choose a password.
- Type FREESPIN20 into the promo code box.
- Click the confirmation link in the email BigWins sends you.
- Fill in the personal details form with your name, date of birth and address. Use details that match your ID, because BigWins checks them against UK licence rules before your first withdrawal.
Winnings from these spins carry 40x wagering. If the spins win you £5, you place £200 in bets before you can cash out.
BigWins Casino Promo Code for High Rollers
HIGHROLLER gives you 50% up to £500 on a single deposit of £300 or more. The bonus lasts 7 days and carries 35x wagering. A £500 deposit earns a £250 bonus, and 35x on £250 comes to £8,750 in bets. Run that sum before you deposit.
How to Enter a BigWins Promo Code at the Cashier
- Log in to your BigWins account or finish registration.
- Open the Cashier and choose a payment method.
- Enter your deposit amount.
- Type the promo code BigWins gave you into the Promo Code field, in capitals as it appears on this page.
- Confirm the deposit and check your bonus balance.
If the bonus does not show up, open live chat and quote the code before you play a single spin.
BigWins Promo Code Existing Customers Can Claim
BigWins sends reload codes to existing players by email, app notification and social media. RELOAD50 adds 50% up to £100 to a weekly deposit. CASHBACK20 returns up to 20% of your monthly net losses. VIP members receive personal codes with higher match rates. Each BigWins promo code existing customers receive by email works once, so use it before it expires.
We check and update this list every week, so bookmark the page if you play often.
Ongoing BigWins Promotions Beyond the Codes
VIP points build up at 1 point for every £20 you wager. You climb from Bronze through Silver and Gold to Platinum, and higher tiers unlock rakeback of up to 17%, weekly reloads and gifts.
BigWins runs slot and live casino tournaments with a different prize pool each time, so check the promotions page before you play. Missions earn you coins that you spend in the BigWins store. The Cash Wheel, Free Spins Wheel and Coins Wheel hand out smaller rewards for logging in.
Deposits and Withdrawals for UK Accounts
The UKGC banned credit cards for gambling in 2020, so you deposit with a Visa or Mastercard debit card, PayPal, Open Banking or Faster Payments bank transfer, or Pay by Phone through Boku. The minimum deposit is £10. Debit card and PayPal deposits post in seconds.
You withdraw to the method you deposited with. PayPal payouts arrive within 24 hours of approval, and bank transfers take up to three business days. Withdrawal limits sit at £2,000 a day, £5,000 a week and £15,000 a month.
Licence Checks and Safer Gambling
Search the UK Gambling Commission register for BigWins and confirm the licence number before you deposit. Set a deposit limit in your account settings when you register. If gambling stops being fun, sign up to GamStop to block every UK-licensed site, or contact BeGambleAware for free support. BigWins is for players aged 18 and over, and bonus terms apply.
Getting More From Each Code
Read the deadline before you claim anything. A 7-day bonus with 35x wagering needs steady play from the first day. Check which games count towards wagering, since slots usually contribute 100% while table games contribute less. Keep your stake below the maximum bet in the terms, because a bigger bet can void your bonus winnings. Enter each code in the field it belongs to: FREESPIN20 at registration, HIGHROLLER and RELOAD50 at the cashier.
