The name on the game has changed; the game hasn’t
Open the catalogue listing for Mega Moolah today and the publisher field reads “Games Global,” not Microgaming. Open Immortal Romance’s listing and it says the same thing, with an added note that Games Global is the studio “formerly known as Microgaming.” Neither game has changed in any way a player would notice; what changed is the name printed under the title.
That is a smaller, more precise claim than “Microgaming rebranded,” and it is deliberately so. A separate website still operates under the Microgaming name as of September 2026, describing itself in general terms as a gaming content provider without mentioning Games Global anywhere on its pages. Whatever the exact corporate relationship between the two names, they are not simply one label swapped for another across the board, and nothing found for this guide pinned down an exact date when the games catalogue started crediting Games Global instead of Microgaming.
Two names, one still on its own site
A visit to microgaming.io in September 2026 turns up a site that talks about itself in the present tense, as a working gaming content provider, with no mention of Games Global on any page checked. That is worth sitting with, because it complicates the tidy version of this story where one company simply renamed itself. Whatever legal or commercial split happened between the platform business and the games catalogue, both names are live and active at the same time, describing overlapping territory in different words.
For a reader, the practical upshot is narrower than the corporate question: a game like Mega Moolah is credited to Games Global wherever this guide could check its listing, so that is the name worth recognising on a casino’s provider page. Whether the wider Microgaming brand still means anything to a specific operator’s back-office contract is a separate question this guide cannot answer from the outside. It is also worth being honest about the limits of this check: neither company’s own website yielded a readable history page from outside a browser session, and no independent encyclopedia entry exists under either name to fill the gap, which is a rarer situation than it sounds for a studio with games this widely played.
Mega Moolah: the jackpot slot that still carries the low RTP that funds it
Mega Moolah’s catalogue page states an RTP of 88.12%, a figure that looks poor next to almost any other slot on this site until the reason becomes clear: a portion of every spin’s stake feeds a progressive jackpot pool shared across every casino running the game. That pool pays out through four tiers, Mega, Major, Minor and Mini, each seeded at a fixed minimum and climbing as players contribute. The listing records a maximum non-jackpot win of 11,250 times the stake and cites the largest Mega Jackpot payout on file at €18,915,872.81, a figure that is a historical record rather than a current balance.
Mega Moolah launched on 28 November 2006, which makes it close to two decades old and still one of the most recognisable jackpot slots in the business. Longevity like that is unusual in an industry where most titles are forgotten within a couple of years, and it is a large part of why the game’s publisher credit matters enough to track. Anyone weighing up a jackpot slot against a straightforward one for real-money play has a wider comparison waiting on this site’s real money casino page.
Immortal Romance and Thunderstruck II, by the numbers
Immortal Romance and Thunderstruck II sit at the other end of the RTP scale from Mega Moolah, since neither funds a shared jackpot pool.
| Title | RTP (catalogue listing) | Released | Notable detail |
|---|---|---|---|
| Mega Moolah | 88.12% (reduced to fund the jackpot) | 28 Nov 2006 | Four-tier progressive jackpot; largest recorded win €18,915,872.81 |
| Immortal Romance | 96.86% | 5 Dec 2011 | 243 ways to win; four distinct free-spin modes |
| Thunderstruck II | 96.65% | 5 May 2010 (remastered 10 Dec 2020) | Norse mythology theme; Great Hall of Spins bonus, four god-themed modes |
Immortal Romance’s listing describes it as “one of Microgaming’s most successful games ever,” a line that has survived the rebrand of the publisher credit above it, and Thunderstruck II’s listing makes a similar point about a game “over a decade old” that “has withstood the test of time.” Both titles are being sold today on the strength of a Microgaming-era reputation, even though the name attached to them on a catalogue page is Games Global.
JackpotCity, and the eight casinos that don’t mention it
JackpotCity’s own homepage names Games Global directly, describing it as “a long-established provider known for innovative online casino experiences,” alongside OnAir Entertainment, Pragmatic Play, Hacksaw Gaming and Blueprint Gaming. That single sentence is the clearest link between this guide’s subject and any partner casino’s actual, visible content, and it is worth reading against the JackpotCity review on this site for the fuller picture of what the casino offers beyond that one provider name.
Nowhere else on the partner list did Games Global or Microgaming turn up. Nomini’s dedicated providers page lists more than a hundred studios by name and includes neither, which is striking given how exhaustive that list otherwise reads; a directory that includes names as niche as Penguin King and Toucan Royale but skips a studio behind Mega Moolah suggests a genuinely separate commercial relationship rather than an oversight. MegaRush’s homepage names Relax Gaming, Play’n GO, Pragmatic Play and NetEnt, again without either name. 21Bit’s homepage and Wild Fortune’s homepage both name a long list of smaller and mid-sized studios, and neither Games Global nor Microgaming appears on either list, the same way neither list includes Playtech. Playzilla’s providers page and its casino landing page loaded without naming any software studio at all, so its coverage is unconfirmed rather than absent.
Three casinos this check couldn’t reach
LeoVegas, Betway and 888casino could not be checked in this session. LeoVegas’s site served a licence notice tied to Germany’s GGL regulator, Betway’s redirected to betway.de, and 888casino’s redirected to a German-market domain, 888slots.de. Each of those is a geo-routing decision made somewhere outside this check, not evidence about what an Irish IP address would actually see, and it is the same wall this site’s other provider guides have hit checking the same three brands.
What that means if Mega Moolah is the reason for choosing a casino
On the record built for this guide, JackpotCity is the one partner casino that visibly carries Games Global content, and by extension the Microgaming-era library that includes Mega Moolah, Immortal Romance and Thunderstruck II. That is not proof the other eight lack it; several of them run provider feeds that could easily include these titles without naming Games Global anywhere on a public page, and the three geo-blocked casinos remain a genuine unknown from here. This site’s how we rate page explains why a dated, checked claim like this one carries more weight here than a casino’s own “hundreds of top providers” marketing line.
A player who wants Mega Moolah specifically should still search for it by name inside whichever account they hold, since a jackpot slot with this much history tends to survive in a library even when the publisher credit behind it has quietly changed twice.
There is also a simpler test worth running before trusting any casino’s marketing copy on this point: search the lobby for “Mega Moolah” by name rather than for “Microgaming” or “Games Global” as a provider filter. A game this old and this widely licensed sometimes turns up under a casino’s own aggregated slots feed without the publisher name being surfaced anywhere in the interface at all, which would make a provider-based search miss it even where the title itself is available.
