The suppliers with no network, and the ones with a hundred

Four of the largest slot suppliers in the world appear on jackpot lists that describe networks they do not operate (two of them because they run nothing of the kind), and the most useful thing this page can do for you is say which of them.

Play'n GO has no documented progressive jackpot product at all, which is to say no supplier page, no announcement and no entry in the trackers (casinolistings among them) that follow every other maker in this business.

We looked for one repeatedly, and because the trackers that cover Games Global, NetEnt, Playtech and Yggdrasil have no column for it, the absence is a finding rather than a gap in our own research; a supplier of high-volatility slots is not obliged to run a pool, and this one does not. A "list" that includes it among the networks is copying another list, and we have seen that error on sites that call themselves authorities!

iSoftBet is a subtler case than that, and the honest answer about it is a qualified one, because the ownership has moved twice in three years. The best source we found states plainly that there are no pooled progressive jackpots in the catalogue, that its prizes are "fixed-seed" and multi-level, and that each operator sets them itself, which means that they do not accumulate across casinos at all.

The company was bought by IGT in July 2022 for about €160 million, and when Apollo Global Management completed its purchase of the IGT gaming and digital division in July 2025, in a transaction of roughly $6.3 billion, iSoftBet went with it. The same source then refers elsewhere to "progressive jackpot" titles, contradicting itself in the space of one article. What can be said is narrower than either claim.

No cross-operator iSoftBet pool has been established, the main mechanic is a four-level "Hold & Win" (named Mini, Minor, Major and Grand) on titles such as Gold Digger Megaways and Aztec Gold Extra Gold Megaways, and the values are configured house by house rather than by the supplier, so that two casinos running the same title are offering two different prizes.

Yggdrasil, where almost nothing is global

Yggdrasil is the opposite problem, and it is the clearest illustration on this site of what the word "network" is made to carry. It has jackpots everywhere and a network almost nowhere, because the architecture is built "per operator" rather than across the industry, and the trackers show it plainly:

• Empire Fortune holds its "Diamond" level in seven separate versions (one for each operator that carries it), running from €25,119 to €68,374, and its "Golden" level from €6,673 to €12,720
• Holmes and the Stolen Stones runs four tracked levels at ten operators, with the "Purple Diamond" between €30,134 and €172,640
• Jackpot Raiders runs four levels at nine operators, the "Legendary" reaching €280,957 (nine pots, one name)
• Ozwin's Jackpots runs four levels at nine operators, the "Archmage" reaching €72,473

Exactly one Yggdrasil jackpot is a genuine pool, and even that one has its distribution restricted to two casino groups, which is a strange fate for a product the company built as a flagship.

Joker Millions, released on 1 April 2015, pays a return of 94.3 per cent on the supplier's own page (the only Yggdrasil return we could verify at source), and it needs all fifteen jokers in a single "jackpot spin" to pay the pot; each joker also carries a fixed mystery win of up to 1,000 coins, which is the hybrid arrangement we describe elsewhere.

It is also, on the figures the trackers publish, in something close to a coma. Joker Millions averages thirty-four weeks and two days between wins, and when we read the tracker (18 October 2026) it had gone three years and thirty-nine weeks without paying, against a record of €7,831,370 taken at LeoVegas in Sweden on 9 November 2018.

One correction belongs here, because the title keeps appearing on lists of Yggdrasil progressives where it does not belong. Jokerizer is not a progressive at all. It pays a fixed "mystery win" of 6,000 coins for three aligned jokers, or a single payment of 1,000 to 6,000 coins for scattered ones, on a quoted return of 98 per cent (ninety-eight, which is extraordinary and comes from a comparison site).

IGT, the company that started all of this

The oldest numbers in this subject belong to IGT, and in our view they are the ones a reader should hold in mind before taking any modern network entirely seriously. Megabucks, introduced in 1986, was the first slot "progressive" of any kind, and on 1 February 1987 it paid $4,988,842.17 in a casino rather than online (a figure still quoted to the cent, thirty-nine years later).

The company today runs "MegaJackpots", which works online and in casinos, "Powerbucks" in Canada, and the Wheel of Fortune series under licence. The totals are on a different scale from anything else here: the Wheel of Fortune games have produced over 1,200 millionaires and paid over $3.6 billion in jackpots since 1996, and Powerbucks has paid 74 jackpots of CA$1 million or more since its Canadian debut in 2016 (seventy-four, in ten years).

What IGT does not publish, after forty years of running these things, is anything at all that a player could use. No "seed", no level structure, and no "contribution" figure exists for MegaJackpots in public (we checked the supplier, the trade press and two regulators' registers), which is a remarkable silence from the company with the longest record in the field.

The individual online wins are documented, and they are modest beside the European pools: $1,247,834 on MegaJackpots Cash Eruption at Caesars Palace Online Casino in New Jersey on 18 January 2026 (one jackpot out of the four IGT reported that month), and a reported £1.7 million on Siberian Storm in 2022 (the second from an IGT announcement we could not reach, because the site refuses automated readers). Wheel of Fortune, incidentally, is not a network of its own; it is a licensed series fed by the two products above.

Light & Wonder, the largest win nobody has verified

The company formerly called Scientific Games has no documented pooled jackpot network online, and this is the one case on the page where we would welcome being corrected. It runs "progressives" on individual titles, configured by market and by operator (which is iSoftBet's arrangement under another name), and we could find no supplier material at all describing a "pool" of the kind Games Global or Relax Gaming operate across casinos.

Its name is attached, even so, to the second largest jackpot in this entire subject. On or about 26 November 2025, a player at DraftKings Casino in Michigan took $22,407,248.55 on Huff N' Even More Puff from a stake of twenty cents (twenty, which is not a typing error), and the figure more than doubled the previous United States record of $9.28 million (set earlier in the same year, on another game).

Three qualifications belong beside that sentence, and not one of them is pedantry, because each changes what the number means. It is a United States record and not a world one, since the WowPot! payout of December 2023 was larger (€38,461,200.95, against $22.4 million).

The underlying "pool" is undeclared, so nobody outside the company knows whether it was multi-operator or multi-state; And the figures come from DraftKings itself, with no regulator having confirmed them publicly. One further correction is needed before anybody repeats a figure from that story.

"Jackpot Party" is a social, free-to-play casino application on the Google and Apple stores, not a real-money jackpot network, and the game carrying the record above is a conventional slot, released in January 2025 with a return of 96 per cent and a "maximum win" of 7,500 times the stake (not a jackpot, on the definition this site uses).

Set all of this against the networks that do publish and a pattern appears: the suppliers who tell you the least about your own money are the ones whose jackpots have the longest history, and the ones who tell you the most are the newest. Forty years of Megabucks, and not one published "seed"! The records has every figure on this page with its date and its source, in the currency it was paid in.
