Whether you are a first-time visitor or returning to 21bit, this guide covers the essential features you need to know.

- Be at least 18 years old or the legal gambling age in your jurisdiction.
- Optional: Enable two-factor authentication (2FA) for added account security.

How Wagering Works
When you claim a welcome bonus, wagering requirements determine how much you must bet before withdrawing winnings. For example, assume a 100% deposit bonus up to $200 plus 100 free spins. The wagering requirement is typically 40x (bonus + deposit).
Let’s say you deposit $100. You receive $100 in bonus funds, giving you a total balance of $200 (real + bonus). The wagering requirement is 40 × $200 = $8,000 must be wagered on eligible games.
If you play slots that contribute 100%, each wager counts fully. The expected loss over the wagering period can be calculated using the house edge. For a typical slot with 96% RTP, the house edge is 4%. Expected loss = $8,000 × 0.04 = $320. That means after completing the wagering, your expected remaining balance is $200 – $320 = –$120 (you lose your deposit and bonus).
To improve your chances, choose games with lower house edges (e.g., blackjack with 0.5%). However, table games often contribute only 10% towards wagering, which increases the required playthrough effectively.
Licence & Player Protection
This casino operates under a licence from the Government of Curacao. While this provides a basic level of oversight, it is not as stringent as licences from Malta or the UK. Players should be aware that winnings from Curacao-licensed casinos may be subject to local income tax depending on their country of residence. We recommend consulting a tax advisor. The platform uses SSL encryption to protect your data and promotes responsible gambling through built-in tools.
