Probability Mobile Casinos
Probability started out as a specialist developer of mobile casino software, with the primary focus being to build games and software optimised for smartphones and tablets. Today, however, the company no longer exists as a solo entity following an £18 million acquisition by GTECH back in February 2014.
Since then, there has been yet another major change because GTECH has merged with IGT. As an organisation, both entities are now known collectively as IGT. Thankfully, though, we can all still access Probability casino games at LadyLucks and Moobile Games.

The Appeal of Probability Software
Probability was one of the key innovators within the mobile casino market. The trend used to be that desktop casinos enter the market later by re-engineering their core experience to function on smartphones and tablets. Along with another couple of developers, Probability was a key innovator in creating content for mobile casinos.
By focusing entirely on the mobile casino experience, Probability was able to deliver games that were designed to excel on mobile – not like desktop games that had been clumsily converted. Nowadays, developers are building games for simultaneous release on desktop and mobile – that is the next step in the evolution, and one that Probability mobile casinos had already addressed. Quite simply, this developer is unique for its mobile focus.
The Best Probability Slots
In terms of gaming content, Probability casinos make the promise of delivering blackjack, roulette, slots, and bingo. From those, though, the Probability slots outnumber all other categories combined. And the slot-based focus carried over into increasing their quality by releasing HD versions. For some recommendations, below are five of the best Probability slots.
Treasure Blast
Treasure Blast showcases the splendour of celebrating Chinese New Year with an abundance of dazzling fireworks. Built with five reels and 40 paylines, Treasure Blast permits a £0.02 minimum stake and a £1 maximum stake on each payline. Wild symbols and free spins are also included in this game with a £1,000 jackpot.
Egyptian Dreams
The Ancient Egyptians were renowned for creating innovations that were years ahead of their time. Well, Probability is continuing that trend with an intriguing feature that sees wild symbols remain on the screen until they earn winnings. What also impresses is that free spins can be retriggered up to 600 times.
Pirates of Chance
Pirates represent a hot theme within slot development, so Probability has wisely covered its bases by launching Pirates of Chance. Within this five-reel slot, Probability has added an incredible 50 paylines to ensure winnings are never far away in this £6,000 jackpot experience. As for wagering, the minimum line bets go from £0.01 to £1.
Money Miner
Decades have passed since gold rushes were a thing, but Probability has revived the memories with its Money Miner game. In addition to the 25 paylines of this five-reel slot, there are many more ways to win thanks to the cactus bonus game that can unlock free spins. Ultimately, the top jackpot is a major £6,000.
Fizz Factory
Fizz Factory deserves a recommendation for its colourful array of delicious treats. The symbols in this five-reel slot will have players yearning for a sweet treat while they try to win on the 50 paylines. Line bets begin at £0.02 and can be upped to £0.50, with the bonus game launching when four cola bottles land simultaneously.
Probability Compared to Other Software
Initially, Probability was short on resources went it was independent. And while the software firm no operates as a subsidiary inside of IGT, the parent company is continuing to use Probability as a niche developer to contribute alongside its IGT slots. As a result, Probability’s remit will likely be a continued development focus on creating mobile slots that could later release at IGT casinos.
A more comparable developer is Cozy Games, but Cozy does not have the same financial support. In recent years, Cozy has powered some 40 sites in the online bingo market, so there is gambling pedigree there. Cozy is attempting to expand in the online and mobile casino markets but still need time and resources to build up its presence.
Probability casinos are designed to excel on mobile devices, so your best experience with these sites will be on a tablet or smartphone. The marketplace is filled with desktop casinos already, thus leaving room for software developers that prefer mobile.
