Before depositing at any online casino, take five minutes to read this checklist — it covers the steps most players skip.
Quick Checklist
- Verify the casino’s license and read reviews.
- Check the bonus terms, especially wagering requirements and game contributions.
- Ensure your payment method is supported for both deposits and withdrawals.
- Complete identity verification (KYC) early to avoid delays.
- Set a budget and stick to it.
- Test the games in free mode first.
How to Sign Up
- Visit 21bit slots and click the Register button.
- Fill in your email, username, and password. Choose a strong password.
- Select your preferred currency and enter personal details (name, date of birth, address).
- Agree to the terms and conditions. Optionally opt-in for bonuses.
- Confirm your email via the link sent to your inbox.
- Make your first deposit and claim the welcome bonus if desired.
Calculating Your Bonus
Imagine you deposit $100 and receive a 100% match bonus up to $200. You now have $200 in bonus funds. The wagering requirement is 30x the deposit plus bonus.
Total wagering requirement = (deposit + bonus) × 30 = ($100 + $100) × 30 = $6,000.
If you play slots that contribute 100% to wagering, you need to wager $6,000 before withdrawing. If your average slot RTP is 96%, your expected loss over $6,000 wagered is $6,000 × (1 – 0.96) = $240. That means you will likely lose your bonus and a part of your deposit.
Formula: Expected value = (deposit + bonus) – (wagering requirement × house edge). In this case, house edge = 4%. EV = $200 – ($6,000 × 0.04) = $200 – $240 = -$40. So you are expected to lose $40 overall.
Always read the bonus terms: game contributions, max bet limits, and expiry.
