London-listed operator GVC Holdings continues to strengthen its online casino offering with new third party content, signing a deal to add more than forty slot games from Gauselmann Group subsidiary Blueprint Gaming.

The operator believes the deal will provide a major boost to the performance of its casino in and selected regulatory markets.

The titles will be launched across GVC's bwin, partypoker, partycasino and Gamebookers sites, with the portfolio of content including premium titles such as Top Cat, Casper and Worms Reloaded, described as three of the most popular titles in the market.

It is the latest third party supply deal to be struck by GVC this year, following agreements with the likes of Realistic Games, Microgaming and iSoftBet.

GVC chief product officer Liron Snir said that he aimed to offer customers the most attractive content available to customers, and that Blueprint's games were "amongst the most exciting out there."

"This deal is another important step on our journey to create the world's greatest online casino," he explained.

"We are delighted to be working with GVC and to be able to offer their customers the great content that we are dedicated to creating," Blueprint Gaming managing director Matt Cole added.

Shares in GVC Holdings plc (Co. Data) (LSE:GVC) were trading up marginally by 0.71 per cent at 634.00 pence per share in London earlier Monday.
