The deposit ladder: your match at each stage
Each qualifying deposit adds 100 FS alongside its percentage bonus. The match rate rises at every stage. Switch between Fiat and Crypto to compare the account types.

A payment method's minimum can differ from the bonus threshold; the bonus card in the Bonuses section gives the exact terms.
Fiat or crypto: choose the account currency
You choose your account currency during registration. USD and EUR accounts use the non-crypto ladder; crypto accounts include BNB, BTC, ETH, LTC, TON, TRX, USDC and USDT.
The welcome package needs no code; the optional code field belongs to a separate bonus mechanism.

What each stage adds per 100 deposited
A 100-unit deposit at the second fiat stage adds 125 units of bonus money before the cap. The figures below show the bonus addition, excluding your own deposit. They illustrate the percentage calculation, not a qualifying minimum.
| Deposit stage | Fiat bonus added | Crypto bonus added |
|---|---|---|
| First | +100 units | +120 units |
| Second | +125 units | +150 units |
| Third | +150 units | +180 units |
| Fourth | +175 units | +210 units |
These additions are per 100 units of your account currency, before the cap in the bonus card; increasing a deposit beyond that cap adds no further percentage bonus.
The wagering and payout conditions apply to the resulting bonus balance.

After the deposit
