The largest prize any house on our list has paid, and the ranking that gets it wrong

Zodiac is the address behind CA$20,059,287 (won on Mega Moolah in January 2019), and almost every table in this trade files that sum third among the largest "progressive" prizes ever paid online. The ordering is arithmetically empty, and the "third place" is an artefact of the currency. The reason is worth a section of its own, because it is the error that every list in this subject has inherited from the one before it.

A Canadian dollar in January 2019 bought roughly two thirds of a "euro", which values the prize at something near €13.5 million (the rate is the one quoted for that month, and we would not use a later one) and therefore below two European wins that the same tables place beneath it. Hardly anybody converts, for the plain reason that converting spoils the sequence, and a table whose third row falls to fifth has to be rewritten.

Nobody has to take our word for the rate. This site gives each amount in the currency it was paid in, with its date, and says plainly that the figures will not line up against one another (a conversion at the rate of the day is the only honest alternative, and it needs a rate published for that day). No jackpot table anywhere does either of those things, and the error is inherited rather than invented: one list copies the order, and the next copies the list.

What the registers say, and what they decline to number

Three authorities answer for this brand, which is one more than most of the international market manages (the "tier" our register assigns it is its strongest licence and not a judgement on the house). The Malta Gaming Authority and the Kahnawake Gaming Commission both hold entries for it (the second keeps a roll of "permit holders" rather than of brands), and the group holds a separate registration with the Alcohol and Gaming Commission of Ontario (for a provincial site that is not this one, under a different company of the same family).

One thing is missing from all three entries.

What our source register does not carry is an account number for either the Maltese or the Kahnawake entry, and we will not supply one from a competitor's page (a licence claim with a borrowed number in it is a false statement rather than an approximation). A reader can therefore confirm that the authority is named and cannot check this particular address against a numbered line in a public list, which is a real difference from a British "licensee", where the account number, the company and the status all sit on one searchable line.

The "platform" is Apricot, carrying the Games Global library, with eCOGRA named as the testing house in the register (which records the same three lines for sixteen sister brands, which is why none of them is a separate technical judgement). Mega Moolah and WowPot! are the two "networks" reachable from this lobby, meaning the two prize funds that many casinos pay into at once rather than two games with large top prizes.

Zodiac's declared target markets are Canada and Great Britain, and the second of those deserves a flag rather than a tick. The British market has its own licensed addresses, and we list seven of them (six carry an account number on the card itself).

A Maltese licence is not a Gambling Commission account, however respectable the authority behind it may be, and a reader in Britain who wants a national scheme for closing an account down will not reach one from here.

How solid the January 2019 figure actually is

One figure does hold up without any of this hedging, and it is the one a reader can check tomorrow: the "Mega" level restarts at £1,000,000, $1,000,000 or €1,000,000 according to the currency of the account. Those are thresholds, not conversions!

The prize itself rests on what our own method calls a secondary rank. Two trade outlets and one jackpot database carry it, and no statement from the supplier confirms either the sum or the casino (Games Global names an "operator" in almost none of its own announcements). The databases put the win at 30 January 2019 while the trade reports give the month alone, so even the "date" is soft; a figure quoted to the dollar beside a month without a day is a combination worth noticing.

We print it anyway, because three independent sources agreeing on a seven-figure sum to the dollar is not nothing, and because the alternative is to leave out the largest single number on this whole site (we would rather publish it with its rank attached). What we decline to do is dress a secondary source as a primary one, which is the single commonest manoeuvre on the pages where this figure appears.

One claim that circulates about this group deserves putting down firmly, because it travels further than the prize itself and it is simply untrue. Several affiliate pages state that three Mega Moolah wins hold records with Guinness World Records, and the Guinness entry carries exactly one, which is a different prize at a different casino in 2015 (€17,879,645, to a named British soldier, on 6 October 2015).

The Zodiac win is not that record and has never been submitted as one, which takes nothing away from the prize itself; a "record" ratified on application is a record somebody applied for, and four later prizes were larger in nominal terms without anybody filling in a form. We would rather set the distinction out than inherit the error, and a reader who meets the "three Guinness records" line elsewhere now knows where it came from.

The group behind the brand, and the two things it changes

Zodiac belongs to Casino Rewards, and two facts about that group bear on a reader more than anything in the lobby. The first is that thirteen sister brands were withdrawn on 12 May 2026, with their players moved across to another address in the same family. Thirteen closures in one day is a "consolidation", and it is the kind of fact a reader is entitled to before opening an account rather than after.

The second concerns a "wagering" condition (the "turnover" a player owes on bonus money before anything at all can be withdrawn). Our register records a requirement of two hundred times on bonus money across these brands (two hundred, not twenty), notes that the figure is absent from the programme's own panel (a check on 12 October 2026 found panel and website disagreeing about another brand of this family), and says it must be read again in the terms of the destination site; a condition of that size is the sort an Ontario standard calls "not reasonably attainable" without substantial losses.

Readers who want to know why no figure appears on the card above will find the answer on our page about method, and the short version is that two Canadian regulators forbid an affiliate to publish an "inducement" at all. In Ontario and in Alberta the prohibition reaches a link and a description rather than merely a number, so your card looks bare above for a reason.

The group is unusually open in one respect that deserves saying out loud, since the rest of this section has been a list of reservations. It publishes a feed of its ten most recent progressive jackpot winners (with the affiliate's own tracking built into it, which is the reason it exists), and that is more disclosure about outcomes (names aside) than almost any operator offers you.

What this address is good for, and who should look elsewhere

On our reading Zodiac suits a reader who wants the oldest and deepest of the Games Global "pools" from a house with three authorities behind it, who is content with an offshore frame, and who understands that the famous prize tells you nothing whatever about your own account. It suits nobody who wants a regulator in their own country, and nobody who expects a complaint to reach a body answerable to their own legislature.

The lobby is a 2001 build on a platform of much the same vintage, and anybody arriving in hope of the five-network breadth of a newer casino will not find it here; what is on offer is the Mega Moolah family, the WowPot! family and a quarter of a century of one "supplier". It is a narrow proposition, and an honest one!
