Games Global slots

Who makes Games Global slots?

Games Global is a supplier and distributor established in 2022 and headquartered in Douglas on the Isle of Man. That year it acquired the games portfolio and distribution business that had been run under the Microgaming name for decades, which is why the oldest titles in its library date back to the early 2000s even though the company itself is young.

The important thing for a player is that Games Global is a network. Its catalogue runs to more than 1,300 titles from over 40 in-house and partner studios. Some studios build exclusively for the network; others are independent companies that use it to reach casinos. When you open a game, the publisher shown on the loading screen may be Games Global, but the designer could be any of those teams.

It is regulated in Great Britain by the UK Gambling Commission and in Malta by the Malta Gaming Authority, so its games reach UK lobbies through licensed casinos only.

From Microgaming to Games Global: what changed for players

Very little changed on the reels. The classic games kept their names, paytables and published RTP figures; what changed was the company holding the contracts and the branding on game credits. In practice you will meet three labels for the same library:

• Microgaming: still used by plenty of casino lobbies, especially for older titles that were filed under it years ago.
• Games Global: the current publisher name on many loading screens and provider filters.
• The partner studio’s own name: for example Gameburger Studios, Triple Edge Studios, Stormcraft Studios or Fortune Factory Studios.

Because labelling varies, a provider filter set to Games Global can miss games that a casino still files under Microgaming, and the other way round. The quickest fix is to search by game name. Our Microgaming slots page covers the pre-2022 history in more depth.

Best-known Games Global slots compared

The table uses the developer’s published default figures. Casinos can run a lower RTP version, so always confirm the live number in the game’s help screen before you play.

Older classics such as Thunderstruck (2004, 9 paylines), Avalon (2006) and Break da Bank Again (2008) are still in many lobbies. Gameburger Studios’ 9 Masks of Fire is another network title you will see often.

Why Mega Moolah’s RTP is only 88.12%

Mega Moolah is the network’s headline progressive jackpot and the clearest example of how jackpot funding changes a slot’s maths. Its published return is 88.12%, roughly eight percentage points below a typical modern slot, because a slice of every stake feeds the jackpot pools that are shared across many casinos.

In pound terms: over a very long run, £100 staked on a 96% slot is expected to return about £96 and cost about £4. The same £100 on Mega Moolah is expected to return about £88.12 and cost about £11.88. Part of that return sits in the jackpots, which very few players ever win, so the regular line wins most people see during a session are smaller still.

This does not make jackpot slots unfair; it makes them a different product. You pay more per spin on average in exchange for a tiny chance at a very large prize. Our guide to how progressive jackpots work runs through the trade-off.

Signature design habits across the catalogue

The Microgaming-era games that still anchor the network share a few habits worth knowing before you play them:

• Unlockable bonus halls. Thunderstruck II’s Great Hall of Spins and Immortal Romance’s Chamber of Spins open more free spins options the more often you trigger the feature, so only the first option is available at the start and the later ones open as you keep triggering the feature.
• 243 ways on a 5×3 grid. Wins pay left to right on adjacent reels in any row position, which raises the hit rate compared with nine or ten paylines. See our guide to paylines vs ways to win.
• Medium volatility as the default. Most of the famous names sit in the middle of the volatility scale, with steadier sessions than modern 10,000x-plus games.

Newer partner-studio releases are more varied: Book of Oz follows the expanding-symbol book format, while Gold Blitz uses 4,096 ways and cash-collect style features. Read each game’s help file rather than assuming a house style.

Games Global partner studios you will see in UK lobbies

The network includes in-house teams and independent studios. A few that appear in our reviews:

Just For The Win is a Swedish studio founded in 2016 whose games reached casinos through Microgaming’s Quickfire platform and now through Games Global.

What a session on Games Global slots looks like in pounds

Take a £50 budget at 50p a spin: 100 spins. On Thunderstruck II at 96.65%, the expected cost of 100 spins is about £1.68 (£50 × 3.35%). On Mega Moolah at 88.12%, it is about £5.94. Those are long-run averages, not predictions; any single session can finish well above or below them, and the house edge applies every time.

The jackpot game also tends to feel slower because more of its return is locked away. If you want a longer session from the same budget, a medium-volatility 96%+ title is the more efficient choice; if you specifically want a jackpot chance, accept the higher average cost and set a session budget first.

UK rules that apply to Games Global slots

Every game in the catalogue follows the same Great Britain rules as any other licensed slot:

• Maximum stake of £5 per spin if you are 25 or over, and £2 per spin if you are 18–24.
• At least 2.5 seconds per spin, with no autoplay, turbo or slam-stop.
• No celebration sounds for a return smaller than your stake, and your net position on screen.
• No feature buy, even where the game offers one in other markets.
• Demo play only after age verification.
