No-deposit codes are popular entry points for new players-they give you a small balance to test the casino without risking your own money. Deposit-match codes reward you for funding your account, typically doubling or tripling your first deposit up to a cap.
How to verify a code is genuine
- 01
Check 21bit Casino's official channels
Visit the promotions page on the main 21bit site, or check your email if you've signed up. Official codes are always listed there first.
- 02
Avoid third-party affiliate codes
Affiliate sites sometimes share outdated or region-locked codes. If a code doesn't work, it's often because it was designed for a different market.
- 03
Test the code before depositing
If it's a sign-up code, enter it during registration and confirm the bonus appears in your account before you fund it.
- 04
Check the terms
Legitimate codes always come with published terms (wagering requirements, game restrictions, expiry date). If a code has no published terms, it's likely not official.

Code expiration and redemption limits
Promo codes have expiry dates. Once expired, they cannot be redeemed, even if you haven't used them yet.
Typical expiry windows:
- Welcome codes: 30-90 days from account creation
- Reload codes: 7-30 days from issue date
- Seasonal/event codes: 1-14 days
Redemption limits also apply. For example, a no-deposit code might be limited to one redemption per player, per household. Deposit-match codes may have a maximum bonus cap (e.g. "100% match up to $500") or a minimum deposit threshold (e.g. "deposit $20 or more").
Always read the terms before entering a code. If you miss the expiry or hit a redemption limit, the code simply won't activate-no penalty, but no bonus either.
