DuelDuelz sister sites and who owns Duelz Casino
Sister site pages are often just random casino lists. This one is evidence-led. We explain the operator, what a real sister relationship means for your bonuses and self-exclusion, and how to verify any named brand yourself.
What a sister relationship means
| Relationship factor | What it means for you | Confidence |
|---|---|---|
| Shared operator (SuprPlay) | Same company, similar terms and KYC | Confirmed for Duelz |
| Shared self-exclusion | GamStop blocks all UKGC sisters at once | Applies |
| Bonus eligibility overlap | One welcome offer per player group | Likely |
| Specific named sister brands | Verify on each brand footer and UKGC | Check live |
Relationship confidence, how we label brands
Why this matters before you sign up elsewhere
- Self-exclusion is shared. GamStop covers every UKGC sister, so excluding from one excludes you from all.
- Bonus eligibility can be shared. A welcome offer may not apply if you already claimed at a sister brand.
- Duplicate accounts are flagged. Operators detect linked accounts, which can delay withdrawals.

Frequently asked questions
What are Duelz sister sites?
Sister sites are other casinos run by the same operator, SuprPlay Limited. They typically share licensing, account systems and bonus rules. We only label a brand a confirmed sister site where operator or licence evidence supports it.
Who owns Duelz Casino?
Duelz is operated by SuprPlay Limited, which holds UK Gambling Commission licence 48695 and a Malta Gaming Authority licence. The same operator running multiple brands is what creates sister site relationships.
Why do sister sites matter?
They share your GamStop self-exclusion and can share bonus eligibility, so a welcome offer at a sister brand may not be available if you already played at Duelz. Duplicate accounts across sisters can also trigger reviews.
