SpinKings runs a UK bonus programme that spreads a matched welcome deposit across three top-ups, adds a weekly cashback ladder, and drops the odd free-spins code for existing accounts. I put £150 through the cashier myself and tracked how the offer credited, wagered through and cleared into a withdrawable balance. The headline deal matches your first deposit 100% up to £150 and adds 150 free spins on top, with the full welcome package worth up to £500 across your first three deposits plus 250 free spins. New accounts can also grab 50 free spins on Big Bass Bonanza using the SpinKings bonus code SKSPIN50. The max cashout sits at £50, and a second code, SKWELCOME20, unlocks 20 spins worth £20. High rollers get 50% up to £500 with the code SKHIGH. SpinKings pays back up to 20% of weekly losses across a five-tier cashback ladder, and a live slots tournament holds a £50,000 prize pool this month. SpinKings operates under a UK Gambling Commission licence, and the cashier runs on Visa and Mastercard debit cards, PayPal, Pay by Phone and Open Banking transfers. Credit cards don't work here, in line with the 2020 UK ban on card gambling deposits.

SpinKings Welcome Bonus
SpinKings rewards you for topping up through your first week rather than depositing once and walking away, because the welcome package splits across three deposits instead of one.
Bonus Type | Offer Details | Wagering Requirements |
First Deposit | 100% up to £150 + 150 free spins | 40x bonus amount |
Welcome Package | Up to £500 + 250 free spins across three deposits | 40x bonus amount |
High Roller | 50% up to £500 with code SKHIGH | 40x bonus amount |
SpinKings adds the bonus to your account within 10 minutes of your deposit clearing, and the offer stays open for 7 days after that.
Tip: Deposit the full £150 on your first top-up. Put in £50 and you match £50, not £150, because the bonus scales with your deposit size.
SpinKings No Deposit Bonus
The SpinKings no deposit bonus lets you spin without risking your own money first.
Bonus | Code | Game | Max Cashout |
50 Free Spins | SKSPIN50 | Big Bass Bonanza | £50 |
20 Free Spins | SKWELCOME20 | Fluffy Favourites | £20 |
Each spin in the SpinKings free spins offer is worth £0.10. Clear the wagering and the winnings move into your withdrawable balance. To get there:
- Clear the 40x wagering requirement on any winnings
- Make a minimum deposit of £10 to unlock withdrawals
- Verify your identity if SpinKings asks for documents
SpinKings checks new accounts against GamStop before releasing any no deposit spins. If you're self-excluded, the offer won't show up in your cashier.
SpinKings Cashback Bonus
SpinKings pays cashback every Monday based on what you lost the week before.
Tier | Cashback | Weekly Loss Range |
Bronze | 5% | £20–£100 |
Silver | 10% | £101–£300 |
Gold | 15% | £301–£600 |
Platinum | 20% | £601–£1,000 |
Diamond | 20% | £1,000+ |
SpinKings caps the cashback payout at £750 a week, and the minimum qualifying loss sits at £20. Cashback wagering runs lower than deposit bonus wagering, so the money clears into your balance faster.
Warning: Check the cashback terms before a tournament week. SpinKings has changed the tier thresholds twice this year without much notice.
Refer-a-Friend SpinKings Bonus
SpinKings doesn't publish a fixed referral table on its promotions page. I asked support through live chat and got confirmation that the casino runs referral credits on request rather than through an automated system.
- Bonus credit for you and the friend you refer
- Free spins packages on rotating slot titles
- Deposit match bonuses tied to your friend's first top-up
Your friend needs to register with your referral link and clear a qualifying deposit before either of you sees the reward.
Seasonal and Special SpinKings Promotions
SpinKings runs limited promotions on top of the standing offers, tied to a slot release or a calendar event.
Promotion Type | Current Offer | End Date |
Prize Pool | £50,000 | Ends this month |
Slots Tournament | Rotating leaderboard | Resets weekly |
Opt in through the promotions tab before you start playing. SpinKings won't count wagers placed before you join the tournament.
Fact: SpinKings ranks tournament leaderboards by bet-to-win ratio rather than raw win amount, so a £5 stake that lands a big multiplier can outrank a £50 stake with a smaller win.
How to Use SpinKings Promo Codes
SpinKings bonus codes unlock spins, matched deposits and high roller offers depending on where you enter them.
When to Enter | Where to Enter | Code Examples |
Registration | Signup form | SKSPIN50, SKWELCOME20 |
Deposit | Cashier/Bonus tab | SKHIGH |
To use a SpinKings bonus code
- Copy the code as written; SpinKings bonus codes are case-sensitive
- Open the registration form or head to the cashier
- Find the "Promo Code" or "Bonus Code" field
- Paste the code in before you submit
- Finish registration or confirm your deposit
SpinKings caps most bonus cashouts at 10 times the bonus amount. Break a wagering term and SpinKings can void the winnings tied to that bonus, so read the offer page before you claim.
Check GamStop and BeGambleAware if a SpinKings casino bonus code starts pulling you back to the site more than you'd like.
