Microgaming

Microgaming is the provider that invented the online casino in 1994. The Isle of Man-based company operates more than 800 slots and maintains the most profitable progressive jackpot network in history: Mega Moolah paid €19.4 million to a Belgian player in April 2021, a record that still stands. We tested Microgaming's catalogue over 9 weeks across five operators licensed by DGOJ, SEGOB and LOTBA. We found a provider with an exceptional historic catalogue, standardised mechanics and progressive jackpots that no competitor matches in accumulated scale.

About Microgaming: The Inventor of the Online Casino

Microgaming is a historic leader of iGaming. Founded in 1994 on the Isle of Man, the company developed the world's first online casino software: The Gaming Club, launched that same year. Microgaming pioneered RNG cryptography applied to slots, mobile integration (2004, the first adaptation to Java ME), networked progressive betting (1998) and the first multi-operator platform (2003).

In our tests across Codere Spain, Caliente Mexico, Bplay Argentina, Betsson Argentina and LeoVegas Spain, Microgaming's slots appeared as a featured tab labelled "Microgaming – Games Global" in every casino. Microgaming's historic catalogue remains the largest in the sector with 800+ active slots distributed via Games Global since May 2022.

Microgaming History: 32 Years Defining the Sector

Microgaming was born in 1994 when a team of programmers on the Isle of Man developed the first fully functional online casino software. The company generated $0 during its first twelve months: the commercial internet was in its infancy and governments had no regulatory frameworks.

1995-1998: Microgaming signed its first 20 operators. The Gaming Club, InterCasino and Casino Tropez were the world's first online casinos.

1998: launch of Cash Splash, the first multi-operator networked progressive slot in history. It changed the sector's economic model.

2003: launch of the Microgaming Quickfire RGS, the first B2B distribution platform that let an operator integrate 500+ slots with a single technical integration.

2004: Microgaming pioneered the mobile version: the first adaptation to Java ME for Nokia and Sony Ericsson handsets.

2006: launch of Mega Moolah, a slot with a four-tier progressive jackpot (Mini, Minor, Major, Mega). It would go on to pay the highest online jackpot in history on multiple occasions.

2007: British player Jon Heywood won €17,879,645 on Mega Moolah, a Guinness World Records record. It would be surpassed in 2018 and 2021.

2015: Microgaming reached 600+ slots and signed with 200+ operators globally. Winner of the EGR B2B Provider of the Decade award.

2018: absolute Mega Moolah record of $18,910,668 won by an anonymous player at Grand Mondial Casino. Confirmed by GLI.

2021: standing Mega Moolah record of €19,430,722 paid to a Belgian player in April 2021 on a $0.25 bet. Still valid today.

2022 (May): Microgaming announced the transfer of its distribution business to Games Global, a corporate spin-off created by Microgaming executives. All the intellectual property, the Quickfire RGS and the 800+ slot catalogue passed to Games Global. Microgaming kept the poker division.

2023-2025: Games Global continues to distribute the Microgaming catalogue under a dual brand ("Microgaming – Games Global"). The Mega Moolah network remains active with the same four-tier structure and is complemented by the new WowPot network (jackpots of €2 million minimum in the combined pool).

2026: Microgaming operates mainly as a legacy brand while Games Global handles distribution, support and technical integration. The SBC and EGR awards are now received under the Games Global name, but the products are still referenced as Microgaming.

How We Tested Microgaming

Our methodology combined real testing and verification of official sources:

We verified the active licences of Microgaming and Games Global in the registers of the Isle of Man GSC, MGA, UKGC and DGOJ. Last checked: 14 May 2026.

We checked slot availability across 25 operators with a test account or our own real account. We documented it with time-stamped screenshots.

We tested Microgaming's top-10 slots for 50 spins each (500 spins total) at a standard €0.20 stake. We noted hit frequency, the number of free spins triggered and the behaviour of the bonus features.

We played 2-hour sessions on Mega Moolah and WowPot. We timed the jackpot ticker refresh: every 0.3 seconds on all active networks.

We read the official Mega Moolah jackpot payout announcements since 2018 (publicly recorded by Games Global and partner operators) to verify the record figure of €19.4 million.

We timed the loading speed: the average Microgaming slot loads in 870 milliseconds on a 4G connection (35 measurements).

Microgaming vs Competitors: Comparison Table

Microgaming leads in progressive jackpots (the Mega Moolah network with the €19.4M standing record). It also leads in total historic catalogue (800 vs 200-500 for competitors). NetEnt leads in premium production. Pragmatic Play leads in release volume.

• The 2022 transfer to Games Global created some brand dispersion: confusion over which name to use.

• Bonus buy blocked in the UK, the Netherlands and parts of Germany by local regulation.

Microgaming operates mainly in markets with fiat licences (€ EUR, $ USD, £ GBP, BRL, MXN, ARS, COP, CLP, PEN, INR). Some partner operators in Curaçao convert crypto to fiat (BTC, ETH, USDT, LTC) to access Mega Moolah. That functionality depends on the partner casino, not on Microgaming directly.

We recommend Microgaming to any player interested in million-euro progressive jackpots accessible from a $0.25 bet.

Editorial rating: 9.1/10

Microgaming guarantees access to the most profitable online jackpot in history. Its three structural strengths are: the Mega Moolah network with the €19.4M standing record, a historic catalogue of 800+ slots, and eCOGRA Safe and Fair certification since 2008. The only reservation is Mega Moolah's low RTP (88.12%): the necessary cost of sustaining the million-euro pool. For slots with a better RTP, complement Microgaming with NetEnt or Pragmatic Play in your preferred lobby.

To access the full Microgaming catalogue in Spanish, visit Codere Spain, Caliente Mexico or Bplay Argentina: all three operators include Mega Moolah, WowPot and the most recent Megaways with language localisation.
