Games from this supplier

Before we look any further into the iSoftBet catalogue, here is some more information about the company and its history.

iSoftBet was founded in the United Kingdom in 2010 by CEO Nir Elbaz. They have pursued an independent path since then and today they provide both table games and slot games to online slot sites, casinos and sports books globally. In fact, there are more than 400 games in their catalogue in total, all tailored to work on mobile, desktop and tablet.

They may not have the profile of NetEnt or a Big Time Gaming but in the industry iSoftBet has established itself as having a good reputation for creating quality products with compelling features. This has been made possible by a team of industry professionals with decades of experience. The current Head of Games, for example, previously worked at titans like Playtech and IGT.

What is perhaps most notable about their game catalogue is the sheer variety on offer. Unlike rivals like Big Time Gaming, No Limit City or Relax Gaming for example, iSoftBet do not focus solely on one area, but instead offer a broad range of themes and styles from 3×3 grid slots to 4,096 payline games and more recently, Megaways™ slots under license from BTG.

iSoftBet now operate in over 15 different regulated markets, including the UK. As well as producing their own games, they also operate an aggregated game platform through which they offer slots from more than 50 game providers to partner casinos across the world.

To help you understand more about what iSoftBet slots have to offer, here is a short guide explaining more about their best games and their features.


New iSoftBet slots are released every month, each with their own theme and gameplay. With over 400 to choose from there is something for every type of player. We’ve picked these 5 favourites to get you started.

Paranormal Activity – this is a 243 payline game played out on 5 reels with 4 rows on each. It’s a truly scary experience as anyone who has seen the movies the game is based on would expect. It comes with a Paranormal Event feature where five wilds are randomly added to the reels. There is also a Bonus Wheel which unlocks any of three free spins rounds – Paranormal Free Spins, Possessed Free Spins or Demon Free Spins. The jackpot is quite low at 750x but the atmosphere is electric!

Shaolin Spin – if you enjoy 243 payline games then you will also like this one from iSoftBet. This is also a 5-reel slot, this time featuring a Kung Fu Master with some tasty moves to score you big wins. The best tricks come in the free spins round where 20 free spins are awarded for five scatters and when the Yin Yang wild lands, expanding in a cross formation to add 4 more wilds to the reels. This is an older release, from 2015, but it packs a punch (literally) with a 97.14% RTP.

Musketeer Slot – an expanding wilds slot based on the classic novel by Alexandre Dumas, Musketeer plays out on 5 reels with 20 active paylines in play on every spin. Things heat up in the bonus round where multipliers of 10x are applied to all wins.  The wilds also lock in place for the duration of the free spins which can help you achieve a top payout of 1,000x.  Musketeer is notable because it showcases iSoftBet’s high quality production values.

Moriarity Megaways™ – if your preference is for the expanding reels format then you could try your luck on this slot that utilises the Megaways™ engine licensed from Big Time Gaming. The theme is Sherlock Holmes, another example of iSoftBet using a famous fictional character to build a game narrative around. The impressive part is not just the 352,947 win ways available, but the huge 42,533x top payout! Cascading Wins and Free Spins with a progressive multiplier are the key to your success!

The Magic Orb Hold and Win – iSoftBet also do Cluster Pays slots rather well! This medium-high variance game takes place on a 7×7 grid. It has an ethereal feel with a neon-lit landscape behind the reels. The objective is to land clusters of 5 or more identical symbols to unlock a win. There are win cascades and six possible modifiers to earn wins from, including wilds, free drops and symbol transforms. You can win up to 20,776x on any spin, making this a must-play slot for iSoftBet fans.


Like all good slot studios, iSoftBet have developed some key gameplay concepts exclusive to their catalogue as well as utilising others that you can find elsewhere. Of course, the Megaways™ mechanic is not exclusive to this studio, but it is one that they are using more and more in the 2020s. And they have found a way to bring their own twist to this popular format with ‘Extreme Paylines’.

In games like Majestic Megaways™ Extreme 4 for example the concept gets stretched further with FOUR reel sets on screen at any one time. This increases the number of win ways to as much as 470,596. There are four bonus features in the game including a free spins round where dropping diamonds onto the reels unlocks the extra three reel sets and boosts the win potential as high as 50,000x.

The innovative production in Majestic Megaways™ Extreme 4 is typical of this studio and shows how they can take a popular concept to new places in their games. You can try this slot at any of the recommended slots sites on this page.


If you want to enjoy more Megaways™ slots from iSoftBet then we recommend these.

  1. Aztec Gold Megaways™
  2. Moriarty Megaways™
  3. Majestic Megways™
  4. Royale With Cheese Megaways™
  5. Piggy Bank Megaways™
  6. Gold Digger Megaways™
  7. Shining King Megaways™
  8. Scrooge Megaways™
  9. Wild Hammer Megaways™
  10. Neptunes Fortunes Megaways™


iSoftBet have a few slots that offer gameplay at a higher RTP than normal. Whilst most online slots run on an RTP of around 96%, these games run at 97% or higher. This means you get better value for your wagering.  Keep in mind that this is just an average, and variance and top payout will affect your winnings too. Here are the top 10 iSoftBet games by RTP.


iSoftBet are not high variance specialists. Their games more commonly fall in the mid-range for volatility which gives you a fairly even distribution of wins. However, every now and then they push out a very volatile slot with a much riskier maths model. For those who like this kind of game, here are a few to check out.


  1. Hot Spin Megaways – 50,000x
  2. Van Der Wilde and the Outlaws – 8,827x
  3. Royale With Cheese Megaways – 50,000x
  4. Hot Shots 2 – 12,150x
  5. Shining King Megaways – 37,500x

iSoftBet formed in 2010, just around the time that mobile gambling was starting to take off. Improvements in mobile technology giving you bigger screen size, better networks and fast streaming, have meant that mobile wagering is now higher even that that on desktop. So it’s no surprise that iSoftBet have made it a strategy of their business to make all their products look as great on any mobile device as they do on your PC or Mac screen at home.

How do they do this? They do it by utilising HTML5 technology to create games that respond to your screen size and operating system, shifting to fit so that they look great on iPhone or Android handsets, as well as any table you use. You can see this when you load up a game like recent release, Ocean Hunter, with its animated sharks swimming behind the reel set that looks superb on the new iPhone 12.

If you want a good casino to try mobile games from iSoftBet then we recommend Casumo that is available through both a browser and a mobile app. Find out more here.


Responsible Gambling has become a headline issue in the UK in recent years and more and more pressure is being put onto operators to ensure that their customers spend responsibly and within limits of affordability.

ISoftBet is licensed by the UK Gambling Commission and only supplies its games to slot sites that are licensed by the Commission too. That means they must adhere to strict rules that ensure gamblers can set deposit and loss limits on their account pages and that operators intervene where plays show patterns of play that may indicate a gambling problem.

In line with the terms of their license, any game that iSoftBet releases in the UK will also have been fully audited and tested by an independent third party to ensure that that the outcome of each spin is totally random and the game behaves according to the advertised RTP as well.

In summary, you can be sure iSoftBet games are fair, secure and safe to play.
