IGT slots include Cleopatra, Da Vinci Diamonds and the Cash Eruption series. Their bonus features work quite differently: a winning combination can disappear to make room for another in Da Vinci Diamonds, while Cash Eruption holds prize symbols through a round of respins. This guide brings together UK casino options, free demos and five game comparisons. We also explain IGT PlayDigital, the MegaJackpots network, and how to read RTP and payouts quoted against a line bet.

IGT slot demos: play for free
Use an IGT demo to follow a payout back to the paytable: which symbols paid, and was the award based on a line bet or the total stake? The balance on screen is virtual, so playing costs no real money and any prizes cannot be cashed out. Demos are for adults aged 18 and over.

Cats is a useful example: a symbol can contain two cats, so counting occupied positions is not enough to understand a win. In Cash Eruption, watch the separate respin counter when another Fireball lands. These are details a demo can help explain; its results do not predict a later session for real money.
On an iPhone, Android phone or tablet, make sure the total bet remains readable alongside the reels. Some IGT rules distinguish the amount on each payline from the cost of the whole spin. That distinction matters more than whether the game looks sharp on a small screen.
Five IGT slots and their bonus features
Cleopatra provides the starting point for this selection, with paylines and a free-spins bonus. The other games show what changes when symbols tumble, count twice or stay locked during respins. The two Cash Eruption releases make a useful direct comparison: they share a bonus format, but award different starting free spins.
| Game | Win layout | Feature to compare |
|---|---|---|
| Cleopatra | Up to 20 paylines | Wild doubling and a bonus multiplier |
| Da Vinci Diamonds | 20 fixed paylines | Tumbling Reels continue after a win |
| Cats | Up to 30 paylines | Single and double symbols |
| Cash Eruption | 20 fixed paylines | Fireballs lock during three respins |
| Cash Eruption: Vegas | 20 fixed paylines | Ten starting free spins and a Giant Gold Coin |
Cleopatra: the multiplier has an exception
Three or more Sphinx scatters trigger 15 free spins in Cleopatra. Bonus wins are tripled, except for the top award of five Cleopatra symbols. A Cleopatra wild also doubles a line win when it substitutes to complete that combination.
Further Sphinx triggers add 15 spins, up to 180 in a bonus round. That is a cap reached through retriggers, rather than the number awarded at the start. The distinction is easy to miss in a short game listing. This section describes the original Cleopatra; Cleopatra Plus and MegaJackpots Cleopatra are separate releases.
Da Vinci Diamonds: what happens after a win
A winning line in Da Vinci Diamonds can pay more than once during a single spin. The symbols that paid disappear, leaving gaps for fresh symbols to fall into. If those replacements form another winning line, you collect that payout too. This continues until a tumble produces no further win.
The IGT game announcement describes this Tumbling Reels feature. It changes the rhythm of the five-reel game without replacing its paylines with cluster wins. Tumbling Reels also operate during free spins, so the feature is not confined to the main game.
Cats: count the cats, not just the symbols
A double Cat symbol counts as two matching cats on a payline. That is how Cats can count as many as ten across five reels. Single and double versions appear throughout the game, with wins evaluated from left to right.
Paw Prints use the same counting principle for the bonus. Five paws award five free spins; six award ten. Two double Paw Print symbols and a single therefore make five paws, despite occupying only three symbol positions. Understanding that count explains both the line wins and the free-spins trigger.
Cash Eruption: three respins can last longer than three turns
Suppose the Cash Eruption counter is down to one respin and another Fireball lands: you now have three respins left again. That reset explains why the bonus can run beyond its initial three turns. Six or more Fireballs trigger it from the main game, with each prize symbol held in place while the empty positions spin. Play continues until all 15 spaces are occupied or the respins run out.
The Volcano symbols trigger a different feature: six free spins. Here, reels two to four merge to display a three-by-three Jumbo symbol. A Jumbo Fireball can launch the Cash Eruption bonus from that round. The free-spins counter and the respin counter therefore belong to different parts of the game.
Cash Eruption: Vegas gives the series a different starting round
Cash Eruption: Vegas begins its free-spins bonus with ten spins when at least three green Gems land. Its central reels also merge into a three-by-three Giant symbol. A Giant Gold Coin triggers the Cash Eruption bonus with nine positions already locked.
In the main game, six or more Gold Coins can trigger the three-respin feature. New symbols reset the counter. Compared with the original’s six starting free spins, the Vegas edition gives you a different opening allowance; the higher count alone does not establish a better expected return.
IGT game series, themes and MegaJackpots
Egyptian imagery connects the Cleopatra titles, while the Cash Eruption collection carries its bonus format into several themes. A familiar name is useful for finding related games, but the suffix identifies which rules to read. Cash Eruption and Cash Eruption: Vegas illustrate that difference without requiring a completely different visual style.
MegaJackpots is IGT’s progressive jackpot series. The network has included UK play, as documented in an IGT jackpot announcement. A progressive prize builds under the network’s contribution rules. That is different from treating every prize labelled Mini, Major or Grand as a growing shared pot.
For current amounts and an explanation of the networks we track, see our progressive jackpot slots guide. The rules inside the chosen game explain its own trigger and eligibility. A jackpot value shown in free play is not money that can be withdrawn.
Our casino game provider guides cover other studios if you want to compare their games with IGT’s catalogue.
About IGT and IGT PlayDigital
IGT PlayDigital supplies online casino content within IGT. The name also appears on land-based slot machines, which helps explain why games such as Cleopatra and Da Vinci Diamonds are familiar beyond online casinos.
The current business took shape after Apollo’s July 2025 acquisition. Funds managed by Apollo affiliates acquired the former International Game Technology PLC’s Gaming & Digital business and Everi. The combined privately held business operates as IGT and is headquartered in Las Vegas. The lottery business remained separate under the Brightstar Lottery name.
The Gambling Commission lists an active remote Gambling Software licence for IGT UK Interactive Limited (account 64570, checked on 1 October 2026). This covers its software business. For the licence behind your deposits and withdrawals, look up the operator that runs your casino account.
IGT RTP, line bets and total payouts
There is no single return-to-player percentage for all IGT games. Read the RTP in the information panel of the edition you open, especially when comparing an original with a progressive jackpot version. A percentage from a land-based machine or a different market may describe another configuration.
RTP is a theoretical long-run average, not the share of your budget you will receive back in one session. Volatility describes the pattern of wins. Neither measure tells you when the next bonus will arrive.
Paytable units need just as much attention. If a 20-line game stakes 1p on each line, the total spin costs 20p. A prize of 1,000 times that line bet is £10, or 50 times the total stake. Calling it “1,000x your bet” without specifying which bet would give a very different impression.
Cleopatra’s rules distinguish line wins from scatter wins in this way: line awards use the line bet, while scatter awards use the total bet. Check the unit beside any maximum win or symbol payout before comparing it with another slot.
Finding IGT slots online in the UK
Search for the exact edition before opening an account to play it. A casino carrying Cash Eruption may have a different selection of sequels from another IGT casino. The same applies to a game shown on a worldwide launch page: the announcement may concern a different market.
When a casino offer includes free spins, its eligible-games list is separate from the slot’s own bonus rules. An offer on Cleopatra does not automatically cover every Cleopatra title. Check the spin value, expiry and any wagering conditions on the resulting winnings; the headline number of spins leaves those details unanswered.
Set a spending limit before playing for money. An almost-full respin grid is not a reason to raise it.

IGT FAQ
Which IGT slots should I compare first?
Cleopatra and Da Vinci Diamonds make a useful pair. Cleopatra’s bonus revolves around free spins and multipliers; Da Vinci Diamonds lets winning symbols disappear and be replaced within the same spin. This selection compares features rather than ranking games by UK player numbers.
Can I play IGT slots for free?
Where a demo is available, it uses virtual credits. You can explore the controls and paytable, but neither the credits nor the prizes can be withdrawn. Demo access does not establish real-money availability at a particular casino.
Are all IGT jackpots progressive?
No. MegaJackpots identifies a progressive series, but a prize labelled “jackpot” in another game can be a fixed award. Read the individual game’s jackpot rules rather than relying on its prize labels.
Is IGT PlayDigital an online casino?
No. It supplies games and technology to operators. Registration, deposits, promotions and withdrawals are handled by the casino you use.
Does a bigger free-spins round mean a better game return?
No. The number of spins is only one part of the bonus. Its symbols, prizes and probabilities matter too. Cash Eruption starts with six free spins and Cash Eruption: Vegas with ten, but those counts alone do not tell you which game has the higher RTP.
