Your first deposit unlocks a 100% match up to £150 plus 150 free spins. I tested the offer with a £150 Visa debit deposit, and the bonus funds appeared in my account within a minute of the payment clearing. Kingdom Casino holds a UKGC licence, so wagering on bonus funds sits at 10x, well below the 35x to 40x you see at offshore sites.
Three of the five offers below need a Kingdom Casino bonus code, and the rest credit on their own. Each section lists the wagering, the expiry and the one rule that caught me out.
- Kingdom Casino Welcome Bonus
- Kingdom Casino No Deposit Bonus
- Kingdom Casino Cashback Bonus
- Refer-a-Friend Kingdom Casino Bonus
- Seasonal and Special Kingdom Casino Promotions
- Using Kingdom Casino Bonus Codes
Kingdom Casino Welcome Bonus
Kingdom Casino spreads its welcome package across your first two deposits, with a third offer for larger bankrolls.
| Bonus Type | Offer Details | Wagering Requirements |
| First Deposit | 100% up to £150 + 150 free spins | 10x bonus amount |
| Welcome Package | Up to £250 + 150 free spins across two deposits | 10x bonus amount |
| High Roller | 25% up to £500 with bonus code "KINGHIGH" | 10x bonus amount |
A £150 deposit gives you £150 in bonus funds, so you wager £1,500 before you can withdraw. Kingdom Casino credits the 150 free spins in batches of 30 over five days, each worth 10p on Starburst. Bonus funds and spins expire after 7 days.
Visa and Mastercard debit cards, PayPal and Open Banking deposits all qualify. Credit cards are banned for gambling in the UK, so the cashier rejects them.
The £5 maximum stake while you clear the bonus is the annoying part. A £10 spin on a slot you like voids the bonus and any winnings from it, so lower your stake before you start.
Tip: Deposit the full £150 to get the full £150 match, as smaller deposits earn a proportionally smaller bonus.
Kingdom Casino No Deposit Bonus
Kingdom Casino gives you 20 free spins for registering and verifying your mobile number, with no deposit required.
| Bonus | Code | Game | Max Cashout |
| 20 Free Spins | KINGFREE | Big Bass Bonanza | £50 |
| 20 Free Spins | KINGAPP | Starburst | £50 |
Each spin is worth 10p, so the offer gives you £2 of play. My 20 spins on Big Bass Bonanza returned £3.40, which meant staking £34 before I could cash out. You can claim one no deposit offer per account. To withdraw your winnings:
- Complete the 10x wagering requirement on your spin winnings
- Make a minimum deposit of £10
- Send Kingdom Casino photo ID and proof of address
Note: The £50 cap applies even if a single spin pays more, and Kingdom Casino removes the excess from your balance.
Kingdom Casino Cashback Bonus
Kingdom Casino returns a share of your net losses each week, and it pays the money as cash.
| Cashback Percentage | Eligibility | Frequency |
| 5% to 15% | All accounts with a real-money deposit that week | Each Monday to Sunday |
The tiers start at 5% for a net loss of £50, rise to 10% from £250 and reach 15% from £1,000, with a £500 cap per week. A £300 net loss returns £30. Cashback carries no wagering requirement, and the money reached my balance by Tuesday evening.
Warning: Losses made with bonus funds do not count towards cashback, and Kingdom Casino can change the terms during special events, so check the promotions page before you play.
Refer-a-Friend Kingdom Casino Bonus
You earn £20 in bonus funds when a friend registers through your personal link, deposits £20 and wagers it.
- Your reward: £20 bonus funds with 10x wagering
- Your friend's reward: 20 free spins on Starburst
- Limit: 10 successful referrals per calendar year
Kingdom Casino checks addresses and payment details, so a referral from someone in your household does not pay out. Send your link only to friends who live elsewhere.
Seasonal and Special Kingdom Casino Promotions
Kingdom Casino runs a monthly slot tournament and a calendar of seasonal drops.
| Promotion Type | Current Offer | End Date |
| Prize Pool | £25,000 monthly slot tournament | Resets on the 1st of each month |
| Seasonal | Daily free spin drops during the Christmas calendar | 1 to 24 December |
You opt in from the promotions tab, and only spins of 20p or more count towards the leaderboard. Rankings follow your highest multiplier win in the month, so a short session on a high-volatility slot can beat a long grind.
Fact: Kingdom Casino pays the top 100 positions in the tournament, and the bottom prizes are free spins rather than cash.
Using Kingdom Casino Bonus Codes
You enter a Kingdom Casino bonus code at registration or in the cashier, depending on the offer.
| When to Enter | Where to Enter | Code Examples |
| Registration | Signup form | KINGFREE, KINGAPP |
| Deposit | Cashier, bonus code field | KINGHIGH |
To use a Kingdom Casino bonus code:
- Copy the code in capitals, with no spaces
- Open the registration form or the cashier
- Find the "Promo code" or "Bonus code" field
- Paste the code
- Complete registration or your deposit
Kingdom Casino bonus codes for existing players arrive by email and text message, and each one carries its own deposit minimum and expiry. If you opted out of marketing, you will not receive them.
Every offer here has a maximum cashout and a maximum stake. Breaking either rule gets your bonus winnings removed, so read the full terms before you claim a Kingdom Casino bonus code. You must be 18 or over to play. Set a deposit limit in your account, and contact BeGambleAware or register with GamStop if gambling stops feeling like entertainment.
