Bonus Math
Let’s break down a typical 21bit bonus. Suppose you claim a 100% match bonus up to $500 with 30x wagering on the bonus amount. You deposit $100, so you get a $100 bonus. Total balance = $200. Wagering requirement = 30 × $100 = $3,000. You must wager $3,000 before withdrawing. If you play 21bit slots with an average RTP of 96%, the expected loss per spin is 4% of wager. So expected cost to meet wagering = 4% × $3,000 = $120. Since your bonus is $100, the expected net result is -$20. If you choose a game with higher RTP, say 98%, expected cost = 2% × $3,000 = $60, making net +$40. Always check which games contribute fully to wagering.
Formula: Expected cost = Wagering requirement × (1 – RTP). Net expected value = Bonus amount – Expected cost.

Banking & Payments
| Method | Min Deposit | Min Withdrawal | Processing Time |
|---|---|---|---|
| Visa/Mastercard | $20 | $50 | 1-3 business days |
| Bitcoin | $10 | $30 | Instant to 1 hour |
| Ethereum | $10 | $30 | Instant to 15 minutes |
| Litecoin | $10 | $30 | Instant to 15 minutes |
Crypto deposits are usually fee-free and faster. Withdrawals may require additional verification for large amounts.
Safety & Licensing
The casino operates under a Curacao license. While this provides basic player protection, it does not cover local tax liabilities. Important: In many jurisdictions, winnings from Curacao-licensed casinos may be subject to income tax. Keep records of your deposits and withdrawals. The 21Bit casino app uses SSL encryption to protect data. Enable two-factor authentication for your account.
Good to Know
If you experience a delayed withdrawal, follow these steps: First, wait the stated processing time (e.g., 48 hours for e-wallets). Then contact support via live chat or email with your transaction ID. Ask for an estimated timeline. If no response within 24 hours, escalate to a manager. Typical reasons for delay: pending KYC documents, bonus wagering not completed, or withdrawal amount over daily limit. Maximum withdrawal limits are usually $4,000 per day, $10,000 per week. If the delay exceeds 7 days, file a complaint with the licensing authority.
