When a Mythoswin bonus fails to appear, the cause is almost always one of the offer’s own conditions: no opt-in, a deposit under £20, or a previous claim. Free spins have their own timing, which is easy to mistake for a fault. Check the list below before contacting support.
How the welcome bonus should credit
The Mythoswin bonus for new UK players is 100% up to £500 + 150 Free Spins. Done correctly, it looks like this:
- Tick the bonus box at registration or in the Cashier before the first deposit.
- Deposit at least £20 with any cashier method.
- The matched bonus appears in your bonus balance straight away — deposit £100 and you have £200 to play with.
- The first 50 free spins on Book of Ra Deluxe are credited, with the next two batches of 50 following on each of the next two days.
Full terms are in our Mythoswin bonus guide.
Common reasons the bonus is missing
- Forgot to opt in: No ticked box, no bonus. Contact live chat before playing the deposit — any manual credit is at Mythoswin’s discretion.
- Deposit below £20: The minimum deposit is £10, but only £20 or more qualifies for the welcome bonus.
- Already claimed a welcome bonus: It is one per person, household and payment method. A second account will not qualify and breaches the one-account rule.
- Account not verified: Deposits and bonuses are only available after age and identity checks — see verification and KYC help.
- Payment method: Not a cause. Every method qualifies, including Paysafecard and e-wallets.
Free spins: batches and expiry
The 150 Free Spins arrive in three daily batches of 50, each worth 10p per spin on Book of Ra Deluxe. Each batch expires 24 hours after it is credited. Spins left unused when the 24 hours run out are lost, and Mythoswin support cannot reinstate them.
Open Book of Ra Deluxe from the Mythoswin lobby or from My Account → Bonuses; the spins load automatically. Free-spin winnings are paid as bonus funds with 10x wagering.

Checking wagering progress
A Mythoswin bonus can be credited and still look “missing” because it sits in a separate bonus balance. Under My Account → Bonuses you will see the bonus amount, the wagering target and progress so far.
| Item | Rule |
|---|---|
| Wagering | 10x the bonus amount |
| Time limit | 30 days |
| Slots contribution | 100% |
| Live casino and table games | 10% |
| Maximum stake | £5 per spin (£2 for players aged 18–24) |
| Example | £500 bonus = £5,000 wagering |
Playing mostly live casino games means progress moves at a tenth of the speed. Stakes above the limit can void bonus winnings.
Troubleshooting checklist
| Check | Where to look | If it’s the problem |
|---|---|---|
| Opt-in ticked? | Cashier → History, deposit details | Contact live chat before playing |
| Deposit £20 or more? | Cashier → History | Bonus cannot be added to smaller deposits |
| First welcome claim? | Your own records | Only one welcome bonus per person |
| Free spins batch due? | My Account → Bonuses | Wait for the next daily batch |
| Spins expired? | Bonus history | Unused spins cannot be restored |
The Mythoswin Olympus Reload (50% up to £100 every Friday, 10x wagering) also needs an opt-in each time.
How to ask support
Open 24/7 live chat (average first reply under 2 minutes) or email Mythoswin customer service (replies within 24 hours). Include your username, the deposit amount, time and transaction ID, and confirm whether you ticked the bonus box. A screenshot of My Account → Bonuses helps. If you believe the terms were applied unfairly, see how to make a Mythoswin complaint, or return to the Mythoswin help centre.
