IGT slots

What IGT slots are and why UK players know them

IGT slots are games built by International Game Technology, one of the oldest names among the slot providers whose games appear at UK-licensed casinos. Its best-known titles, such as Cleopatra, Da Vinci Diamonds and Wolf Run, started life on casino floors and were later converted for online play.

That land-based background shapes how the games feel. Most IGT titles in our checked data use a 5-reel grid with a fixed number of paylines, a free-spins round as the main bonus and moderate swings. They are not built around the giant multipliers of newer studios, so the maths tends to be steadier and easier to follow.

If you are not sure what a studio such as IGT actually does, our explainer on what a game provider is covers the split between the company that designs a game and the casino that offers it to you.

Who owns IGT now: Everi, Apollo and the IGT name

IGT is headquartered in Las Vegas, Nevada. Its gaming business was combined with Everi and, since 1 July 2025, the combined company has been owned by funds managed by Apollo. It now reports three business units: Gaming, Digital and FinTech. The lottery side of the old group went its own way under a new name, while the slot business kept the IGT brand.

The road there was long. The Wikipedia history of IGT from 1975 to 2015 (opens in a new tab) traces the company to William 'Si' Redd's A-1 Supply, and the current International Game Technology article (opens in a new tab) covers the Everi and Apollo deal.

IGT slots on our site: RTP, volatility and max win

These are the IGT games with verified specifications in our checked data. Where a figure is missing, the game's help screen is the place to look; we don't fill gaps with guesses.

Two words in that table matter. "Up to" means the developer offers more than one RTP setting and the casino chooses which to run, and "by version" on Siberian Storm means the same thing in a wider band. The guide to why slots have different RTPs at different casinos explains how to find the version in front of you.

What the IGT RTP gap costs in pounds

RTP is a long-run average: the share of all money staked that a game pays back over millions of spins. The expected cost of play is the total you stake multiplied by (100% minus RTP). It says nothing about a single session, which can land well above or below the average.

The gap looks small per spin, but it compounds with play. Take a £20 budget at 10p a spin. If you replay winnings until you have staked £200 in total, Pharaoh's Fortune at its top setting costs about £6.96 on average, while the 92.52% version of Siberian Storm costs about £14.96. That is why the RTP setting is worth checking before you start.

Signature mechanics in IGT slots

IGT's catalogue shows a clear house style: proven formats rather than novelty. Among the titles in our data you can see three ways of paying out.

• Fixed paylines. Cleopatra and Da Vinci Diamonds use 20 paylines on a 5 × 3 grid, and Wolf Run spreads 40 lines across a taller 5 × 4 grid.
• Ways to win. Fortune Coin pays on 243 ways, meaning matching symbols on adjacent reels from the left count wherever they sit in each column (3 × 3 × 3 × 3 × 3 = 243).
• Both-way pays. Siberian Storm's diamond-shaped 3-4-5-4-3 grid gives 720 ways, and it pays in both directions. One direction gives 3 × 4 × 5 × 4 × 3 = 720 combinations of positions.

Pharaoh's Fortune adds a twist: its 15 lines rise to 20 during free spins, so the bonus round is not just extra spins but a wider net. Themes lean on ancient Egypt (Cleopatra and Pharaoh's Fortune sit in our Egyptian slots round-up), wildlife (Wolf Run and Siberian Storm among our animal slots) and gems.

How IGT helped shape the modern slot machine

Long before online play, IGT was changing how slots worked. In 1978 the company, then called Sircoma, bought Fortune Coin and its video slot technology, an early step from mechanical reels towards screens. (The Fortune Coin slot in our table is a modern game that borrows the name.)

IGT later bought the Telnaes patent on virtual reels, which has since expired. The idea maps a small number of physical reel stops onto a much larger set of virtual ones chosen by a random number generator. With 256 virtual stops per reel, a 3-reel machine has 256 × 256 × 256 = 16,777,216 combinations, which made very large top prizes possible on a cabinet with only a handful of visible symbols. Our guide to random number generators explains how that randomness works today.

IGT's Nevada Megabucks is described as the first wide-area progressive jackpot with a $1 million base prize. Linking many machines to one growing prize is the model behind today's progressive jackpot slots. The wider story is in our history of slot machines.

IGT and Barcrest: the British connection

IGT bought the UK fruit machine maker Barcrest in 1998, and for more than a decade Barcrest was part of the IGT group. Barcrest was later sold to Scientific Games, the company now called Light & Wonder, which is why Rainbow Riches is today a Light & Wonder brand rather than an IGT one. Our Barcrest slots page picks up that side of the story.

IGT slots in the UK: licences and how to check them

The Gambling Commission's public register records the companies it licenses, including software suppliers. It lists several IGT entities, including International Game Technology PLC (account 41794), IGT (64569), IGT-UK Gaming Limited (64568), IGT UK Interactive Limited (64570) and Everi Interactive LLC (61964). Licence status can change, so check the live entry rather than relying on a list.

1. Open the Gambling Commission's public register of businesses.
2. Search by the company name or account number, for example 64570.
3. Check the status shows as active and read the licensed activities and their start dates.
4. Do the same for the casino you plan to use: the operator must hold its own remote casino licence.

UK rules that apply to every IGT slot online

Whoever made the game, a slot played at a British-licensed casino follows the same rules. The Gambling Commission's online slots stake limit guidance (opens in a new tab) sets a maximum of £5 per game cycle for adults aged 25 and over (from 9 April 2025) and £2 for 18 to 24-year-olds (from 21 May 2025). The slot stake limits explainer shows how a game cycle is counted.

• No autoplay: every spin must be started by hand.
• At least 2.5 seconds between the start of one spin and the next, with no turbo or slam-stop.
• No celebrating a return that is equal to or lower than your stake.
• Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players (see feature buy rules).

How to choose an IGT slot for your budget

Picking between IGT titles is mostly about two numbers: how much each spin costs on average, and how bumpy the ride is likely to be. Our general guide on slot volatility covers the second point in depth.

1. Set your budget for the session first, and treat it as the cost of the entertainment.
2. Check the RTP on the game's information screen and note whether it is the top setting.
3. Prefer lower volatility, such as Wolf Run, if you want the budget to last longer with smaller wins.
4. Choose a stake that gives you at least 100 to 200 spins from the budget (10p gives 200 spins from £20).
5. Use the casino's deposit limits and reality checks, and stop when the budget is gone.
