CasinoFlex Casinos

By Becky Mosley

CasinoFlex launched as a software studio in 2015, but this is far from a new company, as much as a rebrand of a very established one.

In 2007, 888 Holdings purchased bingo software developer Dragonfish, and 888 used Dragonfish to carry out experiments in various parts of the online casino gaming world.

These experiments proved successful, and a casino arm of Dragonfish started to form. By 2015, this arm of Dragonfish was so successful that it necessitated its own identity, so it was separated from the bingo arm, rebranded, and CasinoFlex was born.

In-House Preference

For a long time now, 888 has relied on exclusivity as one of its biggest marketing tools, with much of its development occurring in-house, offering a range of titles exclusive to its sites. if there’s one thing that online casino players love, it’s an exclusive.

As the iGaming world has moved on, it is no longer enough to offer games from one developer, even if that developer is you and all your games are exclusive, so CasinoFlex offers over 300 games from third-party software giants as well as their own collection, which includes the hugely popular progressive jackpot slot, Millionaire Genie.

Games

CasinoFlex has been created focusing on slot titles, which is no surprise due to the rising popularity of this particular game type.

The CasinoFlex development team is hard at work creating new slot titles, while the 300+ games that are already on offer through CasinoFlex are also very slot-focused.

The iGaming world is intrigued to see what this new name on the market will produce. With fresh minds and the backing of an established name, CasinoFlex could well be an industry giant very soon.
