Mellstroy Casino welcome bonus at a glance
Four deposit stages make up the package; these figures separate the offer from the requirements for using it.
| Item | Terms |
|---|---|
| Fiat account | Up to 550% + 400 FS |
| Crypto account | Up to 660% + 400 FS |
| Deposit stages | First 4 deposits |

The welcome package covers the opening deposits, while other bonuses have separate eligibility rules.
The four welcome stages
Each qualifying deposit advances the package by one stage. The match rises along either schedule, while the free-spin allocation per stage stays unchanged.
- 1
First deposit
The opening match starts the welcome package. Use its percentage bonus before its free spins. - 2
Second deposit
The next qualifying payment triggers the second stage. The same account currency determines its schedule. - 3
Third deposit
Your third qualifying payment has a higher percentage than the previous stage, subject to the cap in your bonus card. - 4
Fourth deposit
The final welcome payment has the highest percentage in your schedule. This completes the deposit sequence.
The percentage table above sets out the match for each deposit. Completing the deposit sequence does not remove wagering requirements from an active bonus.
No deposit?
No no-deposit cash bonus forms part of this package. Gift Mell Points are a separate reward, and exchanging them for money requires a deposit. The Mell Points rules explain that exchange.
Wagering requirements and caps
Wagering determines when bonus winnings move to your main balance. The percentage bonus and free-spin winnings have separate requirements; crypto uses the same terms apart from the percentages.
x50 percentage bonus
Complete the percentage bonus requirement under the calculation in your bonus card.x40 free-spin winnings
Spins produce winnings on the bonus balance. Complete their wagering before those funds move to the main balance.72 hours to activate
The activation window starts after the deposit. Leaving the bonus unactivated past its deadline cancels it.7 days to wager
Finish within the period in the bonus card. Missing the wagering deadline cancels the bonus.Payout x1
The payout limit is x1 of the bonus amount. This limits the sum payable under the bonus terms.RUB amounts only
RUB: bonus threshold 1,000; bonus cap 14,000 per deposit; FS winnings cap 5,000; maximum bet 400. Other currencies: see the bonus card.
Exact terms are in the bonus card in the Bonuses section. The RUB amounts apply to RUB terms; use the card for your account currency rather than converting these figures.
Where to complete wagering
Place bets from the bonus balance in the casino's bonus wagering category. Casino bonus funds belong to the casino balance, separate from sports bonuses. The categories are listed in the casino games section.
The promotion rules allow wagering of winnings once the account balance falls below the minimum slot bet. After you complete wagering, winnings move to the main balance.

Fiat versus crypto
Your account currency selects the schedule. A crypto payment method alone does not determine the offer: the promotion distinguishes crypto accounts from accounts in other currencies.
| Deposit | Fiat match | Crypto match | Free spins |
|---|---|---|---|
| First | 100% | 120% | 100 FS |
| Second | 125% | 150% | 100 FS |
| Third | 150% | 180% | 100 FS |
| Fourth | 175% | 210% | 100 FS |
| Package | Up to 550% | Up to 660% crypto | 400 FS |
Each percentage applies to its own deposit. The package percentage combines the stages; it is not the match on your first payment. The total free-spin allocation stays the same for both account types.
Choose the account currency at registration
USD, EUR and AED are non-crypto account currencies. The crypto options include BNB, BTC, ETH, LTC, TON, TRX, USDC and USDT. Select your currency in the registration form; the payment rules show how account currency and deposit methods differ.

What each stage adds
A deposit of 100 units lets you compare the percentages without converting currencies. The entries below are arithmetic examples of the bonus addition, before the cap in your bonus card.
| Stage | Fiat addition | Crypto addition |
|---|---|---|
| First | +100 units | +120 units |
| Second | +125 units | +150 units |
| Third | +150 units | +180 units |
| Fourth | +175 units | +210 units |
Amounts are per 100 units of your account currency, before the cap shown in the bonus card for your account currency. Once you reach the cap, a larger deposit does not increase the percentage bonus amount.
The cashier minimum for a payment method can exceed the bonus threshold. Use the card and cashier together when choosing a deposit amount; deposit methods follow their own limits.
How to claim in four steps
The bonus follows a qualifying deposit, with no code to enter. Open its card before paying so that the currency-specific threshold and limits match the amount you plan to deposit.
- 1
Create your account
Enter your phone number, email and password. Accept the terms and privacy policy in the registration form. - 2
Select account currency
Choose the crypto schedule for a crypto account or the fiat schedule for a non-crypto account. - 3
Open Bonuses

Make the deposit
Complete the qualifying payment. The welcome stage credits automatically to the bonus balance.
The form fields are in the registration steps. The Add promo code link opens an optional field; leave it empty for the welcome package. Press Register to submit the form.
After the deposit
The bonus goes to its own balance, separate from your main funds. Free spins become available after you use the percentage bonus. The next welcome stage requires the next qualifying deposit; finishing a stage alone does not activate another one.
Only one casino bonus can be active at a time; a sports bonus can run alongside it on its separate balance. Other casino bonuses wait in a queue, and choosing a replacement cancels the current one.


When the welcome bonus is lost
A withdrawal cancels an active bonus. Missed activation or wagering deadlines also cancel it, as does replacing it with another casino bonus from the queue.
Allowed
- ✓Play eligible casino games from the bonus balance.
- ✓Keep other casino bonuses waiting while the current one runs.
Not allowed
- ✕Abuse bonuses or delay bonus rounds to use with another bonus.
- ✕Keep the current bonus after activating its replacement.
Watch out
- !An unclaimed or unactivated bonus expires at its deadline.
- !Unfinished wagering cancels the bonus when its period ends.
- !A withdrawal can cancel a waiting bonus too.
- !Payment system and bank fees fall to the player.
Actions that end the bonus
- 1
Requesting a withdrawal early
Withdrawing while the bonus is active cancels it, instead of preserving it for later wagering. - 2
Activating the next queued offer
Replacing the current casino bonus cancels it and removes its amount from the bonus balance.
Withdrawals start at 10 EUR or the equivalent. Mellstroy can request documents at any time, and withdrawal requires completed deposit verification. The withdrawal conditions list the account checks and the payment process.

How the package fits with other promotions
Existing players use separate promotions instead of restarting the welcome sequence. Weekly bonuses require more than four deposits; contact-confirmation spins require two deposits before confirmation.
Promo codes
The welcome code field is optional. Vouchers follow a separate activation process.Cashback

Points rewards use a separate exchange system, with a deposit required before exchange.
Contact-confirmation rewards total 40 FS, split between phone and email. The bonus terms distinguish those rewards from the welcome free spins.
