London-listed gaming operator GVC Holdings is further expanding its gaming content through a supply deal with Realistic Games.

The multi-year contract will see the Gibraltar-licensed developer add almost forty slots to GVC’s casino portfolio, beginning later this month.

Online and mobile variants of Realistic’s titles will initially be rolled out for the bwin, partycasino and partypoker sites in regulated markets and for offerings, before a wider roll-out to GVC's other sites.

The titles will also be made available to GVC's B2B partner sites.

"Today's announcement reflects our commitment to keep improving the range and quality of the games we offer our customers," GVC chief product officer Liron Snir said. "Realistic is a great content maker and we are particularly excited about being able to offer our player's their enhanced roulette and blackjack games on mobile for the first time."

Realistic Games chief executive Andy Harris added: "Deals don't come much bigger than this – we are absolutely thrilled to be working with GVC, an international leader in both B2C and B2B markets.

"Liron and his team have been a pleasure to work with and share our passion for product and an understanding that the quality of it will have a significant impact on revenue," he said. "We think the deal will deliver material benefits for both companies, particularly through our market-leading multi-channel table games."
