Midarion hands out more bonus codes than most UK casinos I have tested, and one of them needs no deposit. I signed up, claimed the welcome package, ran through the free spins and requested a withdrawal to see which offers hold up.
I checked every Midarion promo code below in March 2026 and I re-test the list each week. Codes expire without warning, and a stale one wastes a deposit.
Midarion Promo Code UK: Active Bonus Codes (March 2026)
Your first deposit of £10 or more earns a 100% match up to £150 plus 100 free spins. This offer needs no Midarion casino promo code. Midarion credits the bonus once the deposit clears.
All Active Midarion Promo Codes (March 2026)
| Code | Bonus | Type | Expiry | Who Can Use It |
| None needed | 100% up to £150 + 100 free spins | Welcome bonus | Ongoing | New customers |
| MIDRELOAD | 50% up to £100 | Reload bonus | Each week | Existing customers |
| MIDBACK20 | Up to 20% cashback | Cashback | Each month | All customers |
| MIDSPINS20 | 20 free spins, no deposit | No deposit | Limited | New customers |
| MIDHIGH | 50% up to £500 | High roller | Ongoing | Deposits of £300 or more |
How the Welcome Bonus Works
- Create your account if you have not already.
- Deposit at least £10 with a debit card, PayPal or Open Banking.
- You have 7 days to use the bonus.
- Wagering is 35x the bonus amount. A £100 bonus means £3,500 in bets before you can withdraw.
- Midarion releases the 100 free spins on Gates of Olympus in batches of 20 per day.
- Winnings from the free spins cap at £50.
Pro tip: Log in every day. Unclaimed batches expire at midnight, and I lost 20 spins on day three after skipping a login.
Second Deposit Bonus: 55% up to £150 + 100 Free Spins
Your second top-up earns a 55% match up to £150 and another 100 free spins. A £100 deposit gives you £55 in bonus funds.
What You Need to Know
- Deposit at least £10.
- The bonus stays valid for 7 days.
- Wagering is 35x the bonus amount.
- You must claim your first deposit bonus before this one.
The extra spins gave me three more evenings on Gates of Olympus. The £50 win cap applies again, so a big hit gets trimmed.
Third Deposit Bonus: 100% up to £150
The third deposit repeats the 100% match from your first, minus the free spins.
Details
- Deposit at least £10.
- Use the bonus within 7 days.
- Wagering is 35x the bonus amount.
A full £150 bonus at 35x means £5,250 in bets. Size your deposit to the amount you can comfortably wager.

Wagering requirement: You must wager your winnings 40 times before you can withdraw. £10 in spin winnings means £400 in bets. Midarion also asks for ID before it pays out no deposit winnings.
Midarion Promo Code for High Rollers
Large deposits qualify for the high roller offer. A £1,000 deposit earns the full £500 bonus.
High Roller Bonus: 50% up to £500
- Deposit at least £300 to qualify.
- Enter MIDHIGH in the promo code field at the cashier.
- Use the bonus within 7 days.
- Wagering is 35x the bonus amount.
A £500 bonus at 35x adds up to £17,500 in turnover. Check your bankroll before you commit to that.
Midarion Promo Codes and Sports Betting
Midarion runs sportsbook offers separately from the casino bonuses, so you can claim both.
Sports Second Deposit Bonus: 75% up to £150
- Make your second sports deposit to receive a 75% bonus up to £150.
- Deposit at least £10.
- You have 14 days to use the bonus.
- Wagering is 5x, far lower than the casino offers.
Sports Third Deposit Bonus: 50% up to £200
- Your third sports deposit earns a 50% bonus up to £200.
- Deposit at least £10.
- You have 14 days to use the bonus.
- Wagering is 5x.
Football, tennis and cricket bets all count towards the 5x. Qualifying bets need minimum odds of 1.50, so read the terms before you place your first one.

Step 2: Open the Cashier or Deposit section.
Step 3: Choose your payment method and enter the deposit amount.
Step 4: Find the Promo Code or Bonus Code field on the deposit form.
Step 5: Enter the code as shown, including capital letters. Codes are case-sensitive.
Step 6: Complete the deposit. Midarion credits the bonus within a few minutes.

Midarion Promo Code for Existing Customers
Midarion does not leave existing accounts behind. The casino sends reload codes by email, in-app message and social media post. I received MIDRELOAD by email on a Tuesday and it added 50% to a £60 deposit. Each Midarion promo code existing customers receive carries its own expiry date, so read the email before you deposit.
Cashback codes go out each week to active accounts. VIP members receive personal codes with bigger percentages. If you want a Midarion promotional code for an account you already hold, check this page each week. I update the list every Monday.
Ongoing Midarion Promotions and Extra Bonuses
A Midarion casino promo code covers the welcome stage. After that, you have a steady run of offers to choose from.
ComboBoost for Sports Betting
Accumulator bettors get extra winnings from ComboBoost.
- Bet on at least 16 matches to earn up to 1.5x extra on your winnings.
- Four of those matches need odds of 1.30 or higher.
Cashback Each Week: Up to 25%
Midarion refunds up to 25% of your net losses each week on slots and table games. I lost £60 and received £12 back, which works out at 20%. The cashback came with 1x wagering.
Rakeback: Up to 17%
Rakeback climbs as you move up the VIP levels. The top tier earns 17% back on your play.

Quick Tips for Using Midarion Promo Codes
These three habits avoid the mistakes I made in my first week:
- Watch the clock: Every bonus has a deadline. Check how long you have to meet the wagering.
- Read the rules: Some bonuses restrict games or bet types, and casino and sportsbook offers follow different terms. Bets above £5 per spin with bonus funds can void the bonus.
- Enter codes in the right place: MIDSPINS20 goes in the registration form. MIDRELOAD and MIDHIGH go in the cashier.
Deposit and Withdrawal Methods at Midarion
Every bonus except the no deposit offer needs a real-money deposit.
Deposit Methods
- Visa and Mastercard debit cards: Minimum £10, maximum £4,000. Deposits post at once.
- PayPal: Minimum £10. Quick to set up if you already have an account.
- Open Banking / Faster Payments: Minimum £10. You approve the payment in your banking app.
- Pay by Phone (Boku): Up to £30 per day, charged to your phone bill.
- Skrill: Minimum £10, maximum £4,000. A Skrill deposit did not trigger my reload bonus, so I redeposited with a debit card.
- Neosurf: Minimum £10, maximum £4,000.
- Bank transfer: Suits larger sums, with limits that vary and a longer processing time.
Note: You cannot deposit with a credit card. UK rules have banned them for gambling since 2020.
Withdrawal Options and Limits
You can withdraw once you meet the wagering. Midarion sets these limits:
- 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. Midarion asked for ID before my first payout. I uploaded a passport scan and a utility bill, and the account cleared six hours later. E-wallet withdrawals reached me the same day, while debit card payouts took two business days.
