Probability PLC Casinos

Probability PLC was founded in 2003 and focuses on the production of mobile casino games. The two cofounders spotted the opportunity when the first mobile phones with Internet capability came onto the market in the early 2000s.

Probability Mobile Gaming Software

In 2004, Probability launched its first mobile slot game. This was operated under a remote gambling licence, and players could top up their accounts using their mobile phone bill. This was a revolutionary product, as players could only register using their phone—there was no desktop version of the service.

This was radical because no other casino games had been marketed in a 'Direct to Consumer' way like this, but it was successful, and the company grew from there. By 2007, 3G had arrived – Internet take-up was slow, but the iPhone came in June 2007.

From there, the company expanded into the Italian market, and then released Slot o Matic and HD games.

By July 2013, Probability had launched Roulette HD, which gave Apple and Android users an exceptionally advanced and feature-rich experience.

Players can switch between European single 0 and American 00 tables during the same game. There is also an auto spin function for repeated spins and the ability to save popular and successful betting patterns.

Probability now creates interactive, fun, and engaging mobile games. Players want to play them for these reasons, plus the odds of winning cash are fairly high. The in-house design team are always refining the user experience, promotional content, and maths models, and here are a few of Probability's findings: Slots are easier to play when they have fewer features, as complex interfaces are too fiddly on the smaller screen.

Better pay tables on mobile games provide a winning experience in fewer plays than their online counterparts. Probability plc has learned one valuable lesson: differentiation matters. If all sites host the same games, then the competition becomes expensive—the only thing to differentiate sites is bigger incentives.

Therefore, Probability offers its clients exclusive games. The Slot O Matic game platform allows for the creation of more games more quickly in more regulated jurisdictions.

All games are designed in-house by Probability and are available to play on iPhone, iPod, iPad, and Android phones, as well as thousands of other smartphone handsets. Probability plc is registered in England and Wales and licensed by the Government of Gibraltar on a Remote Gambling Licence and the UK Gambling Commission.
