Games Global slots

What Games Global slots are and who makes them

A Games Global slot is any online slot machine published or distributed under the Games Global name. The company was established in 2022 and is based in Douglas on the Isle of Man. Rather than starting from nothing, it took on Microgaming's games portfolio and its distribution business, which is why decades-old favourites such as Thunderstruck and Mega Moolah now carry the Games Global label on casino lobbies and in game help screens.

It helps to think of Games Global as two things at once. It is a content owner, holding the rights to a large back catalogue, and it is a distributor, supplying games from many smaller studios to online casinos through one connection. Our guide to what a slot provider is explains the difference between a studio that designs the maths and a company that delivers the finished game to operators; Games Global does both, which places it somewhere between a studio and an aggregator.

For a player in the UK, the practical result is that the Games Global name tells you less about how a game plays than a single-studio brand would. A low-volatility spy slot and a high-volatility 4,096-ways cash-collect game can both sit under the same logo. The sections below separate the catalogue into its main families so you can judge each game on its own figures. Our providers hub lists the other online studios we cover.

From Microgaming to Games Global: what changed in 2022

Most UK players met these games under the Microgaming name. Our checked data records that Games Global acquired Microgaming's games portfolio and distribution business in 2022. Older help screens and reference sites still say 'Microgaming' for titles such as Avalon and Break da Bank Again, while newer listings say 'Games Global (originally Microgaming)'. They are the same games; only the company holding them changed.

What did not change is the maths. A slot's return to player is fixed by its game rules and paytable, and the 96.01% listed for Avalon or the 95.43% listed for Break da Bank Again is a property of the game model, not of the company name on the splash screen. If a casino offers a different RTP setting, that is an operator choice from versions the supplier makes available, which our page on RTP variants explains.

We have not been able to verify a founding date for Microgaming itself or a date for its first online slot from an official source, so this page doesn't give one. Our online slot history page covers only the dated milestones we could confirm.

The studio network behind Games Global online slots

Games Global's published portfolio is 1,300+ titles from 40+ in-house and partner studios. Help screens usually credit the individual studio, and our checked game data names several of them. Knowing the studio is useful because each one tends to repeat its own design habits, from line counts to bonus structure.

Two patterns stand out. The Microgaming-era classics are mostly 5x3 games built on fixed paylines or 243 ways, the format explained in our guide to 243-ways slots. The newer studios have moved towards wider grids and collect-style bonuses: Gold Blitz uses 4,096 ways on a 6x4 grid, and its follow-up adds a cash-collect option.

Best-known Games Global slots and their published figures

The table below lists Games Global slots we have checked figures for. Where a cell says 'not listed', no reliable figure was available, and you should read the game's own help screen rather than trust a number from memory.

Immortal Romance has the highest listed RTP in the group and a top payout of 12,150 times the stake. Its 2024 sequel, Immortal Romance II, is credited to Stormcraft Studios; the game specification published for its launch (opens in a new tab) describes four character free-spin features plus a Wild Desire feature. The two Thunder games make a neat before-and-after: the 2004 original pays on 9 lines, while Thunderstruck II switches to 243 ways. Our Thunderstruck vs Thunderstruck II comparison sets them side by side.

How Games Global jackpot slots fund Mega Moolah and WowPot prizes

Jackpots are the part of the catalogue most closely tied to the Games Global name. Mega Moolah, released in November 2006, uses a four-tier progressive jackpot wheel, and the same wheel appears in Mega Moolah 4Tune Reels, which plays four 5x3 reel sets at once. The newer WowPot range, such as The Finer Reels of Life WowPot, uses its own progressive jackpot wheel.

The money for a progressive prize has to come from somewhere, and it comes from stakes. A small slice of every bet is set aside as a jackpot contribution, which is why the everyday game returns less. Mega Moolah 4Tune Reels shows this clearly: its published RTP is 90.3%, and 5.3 percentage points of that is the jackpot contribution, leaving about 85% for the reels and the normal bonus.

Worked example: where £20 goes on a jackpot slot

Take 100 spins at 20p on Mega Moolah 4Tune Reels, so £20 staked. Across a very large number of players, about £1.06 of that (5.3%) feeds the jackpot pools and about £17 (85%) comes back as ordinary wins. The remaining £1.94 or so is the house's long-run margin. In any single session, most players never touch the jackpot share at all, so the return they actually experience tends to sit closer to the base figure. Our page on how jackpots are funded goes through seeding and contributions in more detail.

For the original Mega Moolah, the 88.12% figure in our table covers the base game and excludes the jackpot contribution; the total including jackpots is higher. If you compare it with a non-jackpot slot such as Thunderstruck II, you are effectively choosing between a higher everyday return and a small chance at a pooled prize. Our Mega Moolah vs Mega Fortune comparison looks at that trade-off between two jackpot games.

Games Global slot RTP and cost per 100 spins in pounds

RTP is a long-run average across millions of spins, so the clearest way to read it is as an average cost. The formula is simple: total staked × (100% − RTP). At 20p a spin, 100 spins is £20 staked. The table applies that to the Games Global slots we have figures for. Any single session can land far above or below these averages; the RTP explainer shows why.

Two habits show up in these numbers. The non-jackpot games cluster between roughly 95.4% and 96.9%, which is typical of mainstream online slots. Volatility, on the other hand, varies widely: Agent Jane Blonde Returns is listed as low, Book of Oz and Gold Blitz as high. Low-volatility games pay small amounts more often, while high-volatility ones go longer between wins and pay more when they land; the volatility guide explains the difference. Two slots with the same RTP can therefore feel completely different over a £20 session.

Max win on Games Global slots at UK stake limits

A max win is a cap written into the game rules, expressed as a multiple of the stake. It is the most a single spin or feature can pay, not a likely outcome. Online slots in Great Britain are limited to £5 a spin for players aged 25 and over (from 9 April 2025) and £2 a spin for players aged 18 to 24 (from 21 May 2025), so those stakes set the practical ceiling. The figures below assume the game accepts each stake shown; check the bet range in the game.

Progressive jackpots don't fit this table because they are a pool in pounds rather than a multiple of the stake. We don't quote jackpot sizes, which change constantly; the current amount is shown in the game. The rules on stake caps are covered in full on our online slot stake limits page.

Signature mechanics in Games Global slots

Because the catalogue spans so many studios, there is no single Games Global mechanic. Instead, a handful of formats recur.

• 243 ways to win. Immortal Romance, Thunderstruck II and The Finer Reels of Life WowPot all pay matching symbols on adjacent reels from left to right in any position, rather than along drawn lines.
• Fixed paylines on 5x3 reels. Older and simpler games such as Thunderstruck (9 lines) and Lucky Leprechaun (20 lines) keep the traditional line structure.
• Progressive jackpot wheels. Mega Moolah, Mega Moolah 4Tune Reels and the WowPot games send the player to a wheel that picks a jackpot tier.
• Choice-based bonuses. Gold Blitz Extreme lets the player choose between free spins with wild multipliers and the Gold Blitz cash-collect feature; Immortal Romance II offers four character free-spin modes.
• Lines that pay both ways. Ancient Fortunes: Zeus pays its 10 lines from left to right and right to left.

None of these changes the long-run return on its own. A choice of bonus, for example, normally offers options with different volatility rather than one 'better' choice; the game's maths is balanced so each option returns roughly the same over time, which the help screen usually confirms.

How UK rules shape Games Global online slots

Every Games Global slot offered by a UK-licensed casino has to meet the Gambling Commission's game design rules, in force since 31 October 2021. They are written into the remote technical standard on responsible product design (opens in a new tab) and summarised on our slot game design rules page.

• No autoplay: every spin needs a fresh press.
• At least 2.5 seconds per game cycle, with no turbo or slam-stop.
• No celebratory sounds or graphics for a return equal to or less than the stake.
• Your balance and net position for the session shown at all times.
• No bonus buy option in the versions supplied to Great Britain.

Game information is also regulated. The remote technical standard on game rules and the likelihood of winning (opens in a new tab) requires operators to make the rules and return information available to players, which is why the RTP appears in each game's help or information screen. Free-to-play demo versions can only be opened after age verification, a rule in place since May 2019.

Is Games Global licensed in the UK?

Our checked data lists Games Global as regulated by the UK Gambling Commission and the Malta Gaming Authority. Suppliers of online gambling software to British customers need a Commission licence, and you can confirm any company's status yourself. The licence of the casino you play at matters just as much, because it is the operator who is responsible for your account, payments and safer gambling tools.

1. Open the Gambling Commission's public register of businesses (opens in a new tab).
2. Search for the company name shown in the game's help screen or the casino's footer.
3. Check that the licence status is active and note the account number.
4. Repeat the search for the casino's licence holder named in its terms.
5. If either search fails, don't deposit; use a casino you can verify.

How to find Games Global slots and check the version you're playing

Casino lobbies usually let you filter by provider, though the label varies: some say Games Global, others still use Microgaming or the studio's own name. Once you have opened a game, a quick check of its information screen tells you everything that matters.

1. Search the lobby for the game name rather than the provider; filters are not always up to date.
2. Open the game and find the 'i', '?' or menu icon that leads to the rules.
3. Read the RTP figure and compare it with the one in our tables; if it is lower, the casino is using a different setting.
4. Note the minimum and maximum stake; your age band caps the top stake at £2 or £5.
5. For jackpot games, read how the jackpot is triggered and whether all stake sizes qualify.
6. Set a deposit limit in your account before you start.

Our step-by-step guide to finding a slot's RTP shows where the figure sits in typical help screens.

Games Global slot myths, checked

Long-running games attract long-running myths. These are the ones most often attached to this catalogue.

Our slot machine myths guide covers these ideas across all machines, including pub fruit machines, where holds and nudges add a small element of choice but never overcome the built-in payout percentage.

Games Global slots and land-based machines

Games Global's catalogue is built for online play. The slot machines you find in UK pubs, bingo halls, arcades and betting shops belong to the land-based Categories B to D, each with its own stake and prize limits, and are made by a different group of manufacturers. Online slots sit outside those categories and are controlled instead by the online stake limits and design rules above. If you play both, our online vs land-based comparison explains how payouts, speed and limits differ between a pub machine and an online game.

Where to play Games Global slots in the UK

Our partner casinos run large slot lobbies, but game availability changes, so search each casino's lobby for the specific Games Global title you want rather than assuming it is there. Our Coral jackpot slots page shows how one partner lobby organises progressive games.
