Few names in online gambling carry as much history as Microgaming (and few have accompanied us for as long), a company of the Isle of Man that developed its first online casino software in 1994, when most of today's players did not yet have an "internet connection". For many years "Microgaming casino" was a category of its own (the casinos that ran on its software, with the same "lobby", the same games and often the same promotions). Anyone who started playing online in the first decade of the century will remember the "Free Time" offers and the progressive jackpots that made the name famous.
The name still circulates today, above all in "searches" (the ones that bring many of you to this page), but what it designates has changed considerably, and it is worth explaining how before listing the casinos that carry it.
In May 2022 Microgaming completed the sale of its games portfolio and of its distribution business (including the "Quickfire" platform, through which the games reached the casinos) to Games Global, a new company backed by "private capital". The original company now operates under the name Apricot and concentrates on platforms and services for operators. The games (Mega Moolah, Thunderstruck, Immortal Romance and the hundreds of others) are managed and released by Games Global.
For you, as a player, the change is mostly one of "labels". A hypothetical player who looks for a "Microgaming casino" today will find the same titles he or she remembers, but marked "Games Global" in the information panel of the game; the label on the casino's home page, on the other hand, says nothing about the licence or about the way the casino pays, which remain the things to check.
The fame of the name rests above all on the "progressive jackpots", prizes fed by a small share of every bet placed on the same game in all the casinos connected to the "network" (dozens of sites, in some cases). Mega Moolah is the best known of them: in 2015 a British soldier won £13.2 million with a 25-pence spin, a payout that entered the Guinness records, and in 2021 a Belgian player won €19.4 million on one of its versions.
Those prizes have a cost, and we think it right to state it with the figures. Since part of every bet feeds the jackpot, the base game of Mega Moolah returns to the player around 88 per cent (the "RTP"), against the 96 per cent of a typical slot without a jackpot. In other words, for every hundred staked the game keeps on average about twelve instead of four (three times as much), in exchange for a chance, very small, of a life-changing prize!
The casinos below offer the games of the old Microgaming catalogue, today distributed by Games Global, and each card shows the welcome offer published by the operator; several of them belong to long-established groups (Jackpot City since 1998, for example), while the licences differ from one to another and are worth checking on the regulator's register.
Markets: the operators below address the international, non-regulated market; before registering, it is the player's responsibility to check that playing with them is allowed in the country where he or she is located.
Among the titles of the old catalogue, Thunderstruck is the one we know best, having played it in "demo" mode for our review: a slot from another era, with simple graphics and a rhythm that many recent games have lost, which explains why it is still played. The same can be said of Immortal Romance and of the other classics, which today live in the Games Global catalogue and can be tried in demo mode before playing them for money, as we suggest for every slot.
Today the label tells the player which games he or she will find in the lobby, and little else. A casino can offer the Games Global titles together with those of dozens of other "studios" (the companies that make the games), under a licence from Malta, from the United Kingdom or from Curaçao, and it is that licence (not the name of the games "provider") that decides how safe your deposit is. Our guide on how to check a licence explains how to verify it in a few minutes.
The operators listed on our pages address the international, non-regulated market, and it is the player's responsibility to check, before registering, what the law of the country in which he or she is located allows.
The original company now operates under the name Apricot and focuses on platforms for operators, while its games portfolio was sold in May 2022 to Games Global, which now manages and releases the titles.
In 2021 a Belgian player won €19.4 million on one of its versions. In 2015 a British soldier had won £13.2 million with a 25-pence spin, a payout recorded by Guinness.
Because part of every bet feeds the progressive jackpot, so the base game returns around 88 per cent instead of the 96 per cent of a typical slot without a jackpot.
The games are tested and widely used, but safety depends on the casino's licence, which should be checked on the regulator's register before depositing.
Microgaming was, for thirty years, one of the names that built online gambling, and its games are still among the most played. Today the name designates a catalogue more than a kind of casino; the choice of where to play it should follow the usual criteria: a serious licence, clear conditions, and a demo before the first real stake. 18+, and gambling should remain entertainment.
