The welcome package covers the opening deposits, while other bonuses have separate eligibility rules.

Deposit sequence

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. 1

    First deposit

    The opening match starts the welcome package. Use its percentage bonus before its free spins.
  2. 2

    Second deposit

    The next qualifying payment triggers the second stage. The same account currency determines its schedule.
  3. 3

    Third deposit

    Your third qualifying payment has a higher percentage than the previous stage, subject to the cap in your bonus card.
  4. 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.

Terms point by point

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.

Account currency

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.

DepositFiat matchCrypto matchFree spins
First100%120%100 FS
Second125%150%100 FS
Third150%180%100 FS
Fourth175%210%100 FS
PackageUp to 550%Up to 660% crypto400 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.

Percentage calculation

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.

StageFiat additionCrypto 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.

Claiming the package

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. 1

    Create your account

    Enter your phone number, email and password. Accept the terms and privacy policy in the registration form.
  2. 2

    Select account currency

    Choose the crypto schedule for a crypto account or the fiat schedule for a non-crypto account.
  3. 3

    Open Bonuses

    Read the welcome bonus card, including the minimum qualifying deposit and the limits for your currency.
  4. 4

    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.

Keep the bonus active

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. 1

    Requesting a withdrawal early

    Withdrawing while the bonus is active cancels it, instead of preserving it for later wagering.
  2. 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

    Weekly slot cashback uses lost personal funds and its own wagering terms.
  • Other bonuses

    Compare contact-confirmation free spins with weekly deposit offers and their eligibility.
  • Mell Points

    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.
