- Availability update

The undated Official Sweepstakes Rules, checked the same day, repeat that list and limit sweepstakes entry to legal US residents. Indiana and Maine were absent from our July 13, 2026 copy of the Terms and present in our July 20 copy. Operator notice checked 2026-09-28.

The verdict
Zonko’s Season Pass page and FAQ gave different Prime+ reward totals on September 28, 2026. Our purchase email records no package or amount, so it cannot establish which promotion applied or what reached the account.
Score breakdown
Scored with the published, versioned formula: methodology v1 (scoring version e9a89dbe). Affiliate status has zero input.

Is Zonko legit? The short version
Zonko's Season Pass page and FAQ give different Prime+ reward totals, and our file records no payout. Its highest-scoring factor is Terms honesty (60/100); among its lowest is Redemption reliability (50/100).
HIGHER FACTOR SCORES
- Terms honesty 60
Scored 2026-07-07 from Zonko's first-party Terms of Use (zonko.com/help/terms, read 2026-07-07). The terms read as standard sweepstakes boilerplate:…

Terms honesty 60
60/100, mixed (50–69).
Scored 2026-07-07 from Zonko's first-party Terms of Use (zonko.com/help/terms, read 2026-07-07). The terms read as standard sweepstakes boilerplate: they state plainly that the service does not offer real-money gambling, name the operating entity, and set out verification and eligibility rules, but they bind players to individual arbitration with a class-action waiver and do not spell out redemption minimums in the terms themselves. Mid-band honesty.

Zonko: Indiana and Maine excluded, two Prime+ totals, no payout on file
Our Zonko inbox ledger holds 63 threads from April 30 to July 13, 2026, kept as subject lines only. Three concern the account: “Welcome to Zonko” on April 30; “Please verify your email” on May 4, whose subject refers to an email address; and “Purchase Success” on June 26, for which our file records no amount, package or payment method. No subject line in our file concerns a prize request, an identity document or a support reply. We have not been paid by Zonko, so our own records cannot confirm that it pays.
We read Zonko’s public documents on September 28, 2026, when its Terms of Use printed “Last updated: 17 September 2026”. Five copies fetched July 13 through September 21 alternated between June 2, July 14 and September 17 headers; those dates do not establish when clauses changed. The last email in our inbox ledger is dated July 13, and the July 16 email our September 8 note cited also came before our July 20 copy of the Terms, the first in our file that excludes Indiana and Maine. The copies we stored are of the Terms alone, so we cannot say what the undated Rules said while those emails were arriving.
Indiana and Maine joined Zonko’s excluded list in July
Clause 3.4 of the Terms did not list Indiana or Maine in our July 13, 2026 copy. Our July 20 copy lists both, and the Terms dated 17 September 2026 keep them; Rules 2.1 carries the same list. As of September 28, 2026, the state list on this page, taken from our July 7 read, still shows Indiana and Maine as accepted; this note follows Zonko’s later Terms and its Rules, which exclude both.
Our July 7, 2026 record also holds a Zonko page reading “Sorry, Your Location Has Been Blocked” with Colorado as the detected location, though no copy of the Terms we hold lists Colorado. We have not retested it. What we report about Zonko’s state list is information, not legal advice: the list changed between our July 13 and July 20 copies and can change again, and a reader unsure about their own state can ask Zonko in writing or a lawyer licensed there.
Forever Winning LLC was gone from Zonko’s Terms by August 17
Our July 13 and July 20 copies of the Terms named Forever Winning LLC alongside Mamba Limited. The August 17 copy was the first without it, and the current Terms name only Mamba Limited as a party. The footer gives its jurisdiction as the Isle of Man. The same copy began describing games as played with “Virtual Coins” where earlier copies named Gold Coins and Sweepstakes Coins.
Our records group Zonko with Mamba brands Slotomo, Neon Rush and Deal or No Deal Win; the July 7 intake tied it to the latter two’s platform. The one “Zonko Casino” listing on Google Play on September 28 is published by SARL TALBI of Toulouse, France, does not link to zonko.com, and has no tie to Zonko that we can establish.
The June 26 purchase email arrived with an eight-day offer
Our “Purchase Success” email arrived at 19:37 UTC on June 26, in the same minute as a message titled “You’ve Unlocked 8 Days of FREE SC!”. The subjects cannot show what the eight-day message promised or whether its coins reached the balance.
The eight days in that June subject match the length of the Power Boost schedule that a first purchase unlocks on the page we checked September 28. With no amount on file, we cannot tie the June purchase or message to Power Boost. A different subject on June 29, “5 FREE SC with Any Purchase”, expressly attached its offer to a purchase. It does not establish the terms of the June 26 message.
Our July notes distinguish an account gift, paid packages and Stars
Our September 8 note reported that a July 3, 2026 Zonko email invited us to claim 9,000 GC and 5 SC as an account reward and advertised a recurring Happy Hour Mission from 5 to 7 p.m. Central, and that we did not claim or verify the reward in the account. Our inbox ledger holds a July 3 subject from 13:20 UTC, “5 Free SC Ready to Claim Now!”. A separate email it reported, received July 16 UTC, offered Winfinite Wednesday packages of 63,000 GC and 63 SC for $50, or 30,000 GC and 30 SC for $25. That email postdates our ledger. The note described a three-hour July 15 evening window in Central and Eastern time, each designated package available once.
Our inbox carried “Unlock Prime+ Today for 150 FREE SC!” on July 1 and July 8, 2026. On September 28 the Season Pass page gave 150 as the “guaranteed” SC total for the $44 Prime+ purchase, while the FAQ put the same purchase at 144 SC over 30 days. Our file identifies no Prime+ purchase, so it cannot settle which total Zonko credits; the July subject lines match the Season Pass figure.
Our inbox holds prediction-contest emails titled “Predict the Scores. Win Store Stars.” from June 29, July 6 and July 13. Our September 8 note reported that the July 6 contest listed 500, 250 and 100 Stars for first, second and third place and said Stars could be exchanged for SC, without an exchange rate or exact award per correct prediction. It allowed prediction changes before kickoff and closed entries when the round began; we recorded no participation. The Season Pass page bundles 1,000 Stars into Prime+, yet on September 28 neither the Terms nor the Rules mention Stars, and no checked page supplies an exchange rate. Those prizes cannot be counted as Sweeps Coins.
Zonko’s undated Rules supply the redemption figures absent from our July read
When we added Zonko on July 7, 2026, our read of its Terms found no redemption minimum and no playthrough figure, and our file listed both as open items. The undated Rules we read on September 28 set the floor at 100 qualifying SC in 7.3, at $1.00 per SC, and 7.1 requires each SC to be played through at least once unless Zonko states or requires otherwise. Because we stored no earlier copy of the Rules, we cannot say whether either clause existed in July.
Rules 2.7 and Terms 6.12, the Gold Coin clause our September 8 note cited, expire each coin type after 60 days without play in it. Our file records no Zonko play, so it cannot show how either clause is applied.

Score history
Every change to this operator's score, with the reason it was made:

The terms read as standard sweepstakes boilerplate: they state plainly that the service does not offer real-money gambling, name the operating entity, and set out verification and eligibility rules, but they bind players to individual arbitration with a class-action waiver and do not spell out redemption minimums in the terms themselves. Mid-band honesty.
