At crypto casinos, promo code, referral code, bonus code and affiliate code usually mean the same thing: a short string entered on the registration form that links your account to a specific offer. Some codes are public, some are exclusive to a partner, and a few — like Shuffle's SHFLVIP 200% deal or Rainbet's BOOST20 rakeback boost — unlock offers that are not shown to visitors who arrive without one.
Where to enter a code
Every brand on our list has a code field at registration, sometimes hidden behind a "Have a code?" link:
| Casino | Field label | Code | Can be added later? |
|---|---|---|---|
| Rainbet | Referral code | BOOST20 |
Within 24h, under Rewards |
| Stake | Code | GETRAKEBACK |
Within 14 days, Settings → Offers |
| Roobet | Promo code | roospins |
At first deposit |
| Shuffle | Referral code | SHFLVIP |
Within 48h |
| Gamdom | Referral code | 15BOOST |
Rewards page, before first deposit |
| BC.Game | Referral/promo code | qs57bd7r (lowercase) |
Before first deposit |
| Coins.Game | Promo code | MAXBONUS |
At deposit |
| Duel | Referral code | MAXRB |
Before first bet |
| Thrill | Referral code | maxrakeback (lowercase) |
Before first bet |
Our strong advice: enter the code at signup. Retroactive activation windows exist but are inconsistently honoured, and rakeback is never backdated.
Why codes change what you get
Casinos pay partners for referred players and let partners choose which offer to attach. A partner that negotiates a better deal can only deliver it through its code. That is why a 200% match exists at Shuffle for SHFLVIP users while the public offer is smaller, and why Rainbet's rakeback boost is tied to BOOST20. There is no catch — the terms are published, and the casino honours them because the code is the audit trail.
Codes vs links
A tracking link (the buttons on this site) usually pre-fills the code. If you register from a link and the code field is blank, type it in anyway. Using both is harmless; using neither forfeits the offer.
Rules that apply to all codes
- One account per person, per casino. Duplicate accounts void bonuses and balances.
- Codes are for new accounts unless stated otherwise.
- Case matters at some sites — BC.Game and Thrill codes are lowercase.
- Codes do not change KYC, withdrawal limits or game rules.
- If a code is rejected, contact support before depositing; they can attach it manually.

Frequently asked questions
What is the difference between a referral code and a promo code?
At crypto casinos, nothing meaningful — both are entered at signup to attach an offer. 'Referral' usually implies a partner, 'promo' a campaign.
Do promo codes expire?
Partner codes like ours are long-running; campaign codes can expire. Every code on this site is re-verified weekly and the date is shown at the top of each page.
Can I use a promo code on an existing account?
Generally not. Some sites allow adding a code within a short window after registration; rakeback is never retroactive.
Is it safe to use codes from this site?
Yes. They are official partner codes recognised by each casino. We disclose that we earn a commission; it does not change your terms.
