One company.
Five sites.
Spinfinite, Deal or No Deal Win, Zonko, Spinsly and Amazon Jackpots are all run by Mamba Limited, with the same rules and the same payouts. Each one has the same $20 first buy for new players, so pick the one you like.
- 40 SCright away
- 1 wheel spin2 to 15 SC*
- 25 SCover 8 days of logins
Buying is optional and bonus SC can be lost. * Wheel slices seen at Spinfinite; reported by reviews on the other four.
Same offer on all five.
Pick the one you like.
Each site's $20 first buy is the same: 40 SC and 60,000 GC now, a wheel spin, and 25 SC with 52,000 GC over the next 8 logins.
One site at a time. The five sites' terms (4.26.1 and 4.26.6, updated Nov 3, 2026) list multiple accounts across their network as possible bonus abuse. Ask support before you open a second one.
Know one,
know all five.
We read the sweepstakes rules, FAQ and promotions page on all five sites. The rules below match on every one of them. If you've redeemed at one, you already know how the other four work.
Sources: each site's Sweepstakes Rules, FAQ and promotions page, checked Nov 4, 2026. Spinfinite we also checked in our own account. Same company also means the same catches: no SC at sign-up, debit card only, and the 100 SC floor.
Checked, not copied.
We check the sites themselves
Every number here comes from the site's own rules and promo pages, and Spinfinite from our own account. Anything we only saw in reviews gets a *.
We keep it current
We re-check offers and terms regularly and log every change on the homepage, so the deal you see is the deal you get.
Our links carry the full offer
Our links take you to each site's full new-player offer. They also support StackSweeps at no cost to you, which keeps these guides free.
Before you buy
One account across the group
Their terms count multiple accounts across the Mamba network as possible bonus abuse. Pick one site, and ask support before opening another.
100 SC to redeem
A first buy gives 65 SC plus the wheel, so you'll need to win some to reach the 100 SC minimum.
Optional, and it can be lost
The first buy is $20. SC is not money and can be lost in play. Only spend what you'd spend on fun.
Not open in 14 states
No prize play in CA, CT, DE, ID, IN, LA, ME, MI, MT, NJ, NV, NY, TN, WA on any of the five. They're 18+; StackSweeps only promotes to 21+.
Mamba sites FAQ
Can I claim the first-buy offer on all five sites?
Don't assume so. The five sites share one set of terms, and section 4.26 (updated Nov 3, 2026) lists operating multiple accounts across their network as an example of bonus abuse, and says abuse on any affiliated site counts. They can close accounts and void balances. We've asked Mamba to confirm in writing and will update this page. Until then, pick one site, and ask support before you open a second.
Are all five sites really the same company?
Yes. Each site's own terms say it is owned and operated by Mamba Limited, incorporated in the Isle of Man. The sweepstakes rules, payout method and restricted states are the same on all five.
What does the first buy cost?
Nothing to sign up. The first buy is optional: $20 for 40 SC and 60,000 GC right away, a wheel spin worth 2 to 15 SC, and 25 SC with 52,000 GC over the next 8 daily logins.
How do I pick between them?
The rules, payouts and first buy are the same on all five, so pick the look and the extras you like. Read each guide for what's different: Spinfinite has an Android app and an NFL picks game, Zonko and Amazon Jackpots list a $44 Prime+ Pass.
Do my coins move between the sites?
No. Coins, redemptions and the 100 SC minimum are per site. 60 SC on one site and 60 on another can't be combined to reach 100.
Which states are excluded?
All five exclude CA, CT, DE, ID, IN, LA, ME, MI, MT, NJ, NV, NY, TN, WA.
#ad. Claim links are sponsored. 21+. No purchase necessary; each site has a free mail-in request worth 3 SC. Sweeps Coins are not money and can be lost. Prizes are taxable.
