IGT slots on mobile bring Las Vegas cabinet classics such as Cleopatra, Da Vinci Diamonds and Wolf Run to UK casino apps. The games are simple to follow on a phone, but several have RTPs below 95% or come in a range of versions. This guide covers IGT’s history and current owners, compares six of its slots and shows what the RTP differences cost.
IGT is headquartered in Las Vegas and has been owned by Apollo-managed funds since 1 July 2025, combined with Everi.
Its history includes buying Fortune Coin, maker of the first video slot, and owning Barcrest from 1998 to 2011.
The IGT slots listed here have RTPs from 94.93% to 96.52%, and Siberian Storm’s versions run from 92.52% to 96%.
At 92.52% RTP, £100 staked costs £7.48 on average, against £4 at 96%.

IGT slots on mobile: Las Vegas classics in UK apps
IGT, short for International Game Technology, built its name on casino-floor machines in Nevada long before online slots existed. Its online games keep that feel: five reels, clear paylines and one main bonus round, usually free spins. On a phone that makes them easy to read and quick to learn.
The catch is the maths. Several IGT titles have RTPs under 95%, and some are published as a range or with an up-to figure, so the version in your app may be lower than the best case. We put a pound figure on that gap below.
Our slot provider guides cover other studios, and full game reviews sit in the mobile slot reviews hub.
IGT’s history: from A-1 Supply to Apollo
IGT began in 1975 as A-1 Supply, founded by William ‘Si’ Redd. It was renamed Sircoma in 1978 and became International Game Technology, listed on the stock market, in 1981. The Wikipedia history of IGT from 1975 to 2015 (opens in a new tab) has the fuller story.

Two of those links touch other studios we cover. Barcrest, the maker of Rainbow Riches, was owned by IGT for 13 years, and it now sits with Light & Wonder. IGT also later bought the Telnaes patent on using a random number generator to pick reel stops, the idea behind virtual reels and the RNG approach used in slots today.
Who owns IGT now, and its UK licences
In February 2024 IGT’s parent announced a plan to split off its gaming and digital business and combine it with Everi. Apollo agreed in July 2024 to buy the combined business, and since 1 July 2025 IGT has been owned by Apollo-managed funds, as the current Wikipedia entry for IGT (opens in a new tab) describes. The gaming business kept the IGT name and is based in Las Vegas, with Gaming, Digital and FinTech units.
The Gambling Commission’s register lists several IGT companies, including International Game Technology PLC (account 41794), IGT (64569), IGT-UK Gaming Limited (64568) and IGT UK Interactive Limited (64570), plus Everi Interactive LLC (61964). These are supplier licences. The casino app you play in needs its own operator licence, which covers your account and money; see how casino apps are licensed in the UK.
IGT slots compared: RTP, volatility and max win
These six IGT games have verified specifications. Where a figure isn’t confirmed, the table says so.
Pharaoh’s Fortune was released in 2006, while Da Vinci Diamonds came online in 2012 and Wolf Run in 2014. Medium and low-to-medium volatility is the norm here, which suits players who prefer a steadier session to chasing very large multiples.
Cleopatra and Pharaoh’s Fortune: IGT’s Egyptian pair
Cleopatra is about as simple as a feature slot gets. The Cleopatra wild substitutes for everything except the Sphinx scatter, and three or more Sphinxes give 15 free spins with every win tripled. That’s the whole game, which is why it reads so clearly on a phone.
Pharaoh’s Fortune adds a pick stage. The game logo is the wild, and landing three green Pharaoh bonus symbols on a payline starts the bonus. Before the spins begin, you pick pyramid blocks that add extra spins or raise the multiplier. During the round the symbols change, the game moves to 20 lines, and more bonus symbols on the first three reels add spins.
Da Vinci Diamonds, Wolf Run and Siberian Storm: how they pay
Da Vinci Diamonds uses tumbling reels: winning symbols disappear and new ones fall into place, so one spin can produce several wins. Three bonus symbols give 6 free spins, the tumbles carry on during them, and more bonus symbols add extra spins.
Wolf Run relies on stacks. Its howling wolf wild can fill whole reels, and three bonus symbols on the middle three reels give five free spins with extra wilds and bonus symbols added. The round can be retriggered.
Siberian Storm uses IGT’s MultiWay Xtra format, with five reels in a 3-4-5-4-3 diamond shape and 720 ways that pay both left to right and right to left. The wild lands only on the middle three reels, and five Tiger Eye symbols give eight free spins, which can be retriggered. Because wins can run in both directions, it’s worth reading the paytable before you play.
Fortune Coin: an old name on a modern slot
Fortune Coin is a name with history at IGT. Fortune Coin Co. built the first video slot machine in 1976, testing it at the Las Vegas Hilton, and the company was bought in 1978 by the business that became IGT.
Today’s Fortune Coin slot is a modern game on five reels with 243 ways to win. Fortune Coin symbols can land on the reels and award free games, cash prizes or entry to a jackpot feature with four jackpots. Its RTP is published as up to 96.20%, so check the version in your app. Our guide to jackpot slots on mobile explains how in-game jackpots usually work.
Reading IGT’s up-to RTPs: what the range costs
An up-to figure tells you the best version available, not the one your casino runs. Standard game maths gives the average cost as stake multiplied by the house edge, so here’s what the IGT figures mean if you stake £150 in a session, for example 300 spins at 50p:
Apps don’t lower RTP just because you’re on a phone. If the figure differs from desktop, it’s because the casino runs a different version. Our page on whether RTP is the same on mobile explains this myth.
Playing IGT slots on your phone, step by step
None of our partners publishes which IGT games it carries, so check the app yourself using these steps.
Set a deposit limit before your first deposit; UK apps must prompt you to choose one.
Search the casino app’s lobby for the game by name, such as Cleopatra.
Open the game and find its help or paytable screen.
Check the RTP. For Siberian Storm, Pharaoh’s Fortune and Fortune Coin, compare it with the range in our table.
Pick a stake within UK limits: £5 per spin if you’re 25 or over, £2 if you’re 18 to 24.
Watch the net position and session time on screen, and stop when you reach your limit.
Five-reel, three-row games like Cleopatra generally fit a phone screen well; our guide to landscape vs portrait mode explains how orientation varies by game. If you play on an older handset, see casino apps on older phones.
UK rules for IGT slots in British casino apps
IGT’s online slots in Britain follow the same rules as everyone else’s. Since 31 October 2021 there has been no autoplay, turbo or slam-stop, each spin must take at least 2.5 seconds, and a return equal to or below your stake can’t be celebrated. These games were built for casino floors, but in a UK app they run at the set pace.
The online slot stake limits (opens in a new tab) cap stakes at £5 per spin for over-25s from 9 April 2025 and £2 for 18 to 24-year-olds from 21 May 2025. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players. See our pages on slot stake limits and game design rules.

Novomatic is the closest match, with simple ten-line games built on a land-based heritage. Barcrest shares part of IGT’s history, and Playtech offers another big catalogue of classic-style games. To compare apps by slot range, see our best slot apps UK ranking.
Alternatives with a slot welcome offer for IGT players
We don’t have an IGT offer, and whether a partner app carries Cleopatra or any other IGT title isn’t published, so check the app’s game lobby. The partners below each have a slot welcome offer for new customers aged 18 or over, with terms applying. The spins go on selected games named in the terms.

Frequently asked questions
Can you play IGT slots on mobile in the UK?
Yes. IGT’s online slots run on phones and tablets inside UK-licensed casino apps and mobile browsers, loaded through the operator’s lobby. There’s no IGT app of its own. Each casino chooses which titles and versions to carry, so search by game name and check the help screen. Our guide to slots on mobile covers the basics, and download a casino app on iPhone helps with setup.
Who owns IGT?
Since 1 July 2025 IGT has been owned by Apollo-managed funds and combined with Everi. The deal followed a February 2024 plan to separate IGT’s gaming and digital business from its lottery business. The gaming company kept the IGT name, is based in Las Vegas and has Gaming, Digital and FinTech units. Our game provider entry explains how studios like IGT fit into casino apps.
What is the RTP of Cleopatra?
Cleopatra has a published RTP of 95.02%, which means a house edge of 4.98%, or about £4.98 lost per £100 staked on average over the long run. It’s rated medium volatility. A casino could run a different version, so check the RTP in the game’s help screen. Our full Cleopatra review explains its free spins, and our RTP entry covers what the number means.
Why does Siberian Storm have different RTPs?
Siberian Storm is published in several versions with RTPs from 92.52% to 96%, and each casino chooses which to run. The game looks the same, but on £150 staked the lowest version costs £11.22 on average against £6 for the top one. The help screen shows which you’re playing. Our Siberian Storm review covers the MultiWay Xtra layout in detail.
Did IGT make the first video slot?
Not directly. The first video slot was built by Fortune Coin Co. in 1976 and tested at the Las Vegas Hilton. In 1978 the company was bought by Sircoma, the business that was renamed IGT in 1981. IGT also later bought the Telnaes patent behind virtual reels. Our page on RNG casino games on mobile explains how random number generators decide slot results today.
Is IGT connected to Barcrest?
Yes, historically. IGT bought the British fruit machine maker Barcrest in 1998 and sold it to Scientific Games, now Light & Wonder, in 2011. That means Barcrest spent 13 years inside IGT before moving on, and today it sits under Light & Wonder alongside other studios in that group. Our Barcrest slots on mobile page tells that side of the story.
Which IGT slot is best for a small budget?
Lower-volatility games tend to stretch a small budget further, and Wolf Run is rated low to medium, with Cleopatra and Pharaoh’s Fortune at medium. Lower volatility usually means smaller, more frequent wins, though the house edge still means losses are likely over time. Wolf Run’s RTP is 94.98%, so check the cost too. Our low stakes casino games guide has more ideas.
Is IGT licensed by the Gambling Commission?
Yes. The Commission’s register lists several IGT companies, including International Game Technology PLC (account 41794), IGT UK Interactive Limited (64570) and IGT-UK Gaming Limited (64568). Those are supplier licences for the games. The casino app you play in needs its own operator licence, which is what protects your account and money. Our guide on how to spot an unlicensed casino app shows what to check.
