New Launch Brief · 2026
Spinfinite
Mamba Limited's first US sweepstakes brand, and the one Zonko was built to follow.
This is a brief, not a review, and Spinfinite has no Lodge score. It launched in 2026, so there is no payout track record to assess — and payout behaviour is the thing we weight most heavily. Here is what we can verify, what we can't, and what we'd want to know before recommending it. Why we work this way →
What we know
| Launched | 2026 — Mamba's first US brand |
|---|---|
| Operator | Mamba Limited (also Zonko, Deal or No Deal Win) |
| Sister brand | Zonko, launched March 2026 |
| Games | Not verified by us |
| Redemption | Not verified by us |
| Support | Not verified by us |
Spinfinite is the first US sweepstakes brand from Mamba Limited, the operator that went on to launch Zonko in March 2026 and also runs Deal or No Deal Win.
We have less verified detail on Spinfinite than on almost any other room we list, and we're not going to fill that gap with plausible-sounding numbers. What we can say is what the operator relationship implies: sweeps brands in a group typically share payment rails, KYC procedure and account-review policy, so Spinfinite and Zonko are likely to behave similarly at redemption time.
That makes the Zonko brief the most useful thing we currently have to offer about this brand — including its 100 SC floor, 10-business-day payout quote and absence of live chat. Treat those as the working assumption here until either of us can confirm otherwise.
What we don't know yet
The honest list. These are things we'd normally publish in a full review and currently can't verify:
- Game count and providers
- Redemption minimum and payout speed
- Welcome offer structure
- State availability
- How it handles a redemption that goes wrong — the thing that matters most, and the thing no new casino can demonstrate yet
What we'd do
Treat Spinfinite the way you'd treat any room that opened this year: it's an unknown, not a recommendation and not a warning. If you try it, take the free coins, reach the redemption minimum, and test a withdrawal before you build a balance. Your own first payout is worth more than anything written about it — including this page.
When it has a track record we'll write a full review with a score, the same as the 31 rooms we've reviewed properly. Until then this page stays honest about its limits.
Rooms with a record instead
If you'd rather not be the one testing an untested operator, these are reviewed in full with the receipts:
- Best sweepstakes casinos — eight ranked, each with its downside printed
- Lowest redemption minimums — where the 10 SC floors are
- Fastest payouts — and the four rooms with documented delays
- Legal states — 14 are now closed to sweeps entirely
- All eight 2026 launches compared
