The AIM-listed mobile gaming developer said the agreement was to roll out its “Slingo Originals” content worldwide, with GVC distributing the content across all of its sites.
The group added that GVC would also have a six-week exclusive period of hosting its new 'BlackJack X-Change' casino game.
The agreement follows an announcement in July 2017 that GVC would distribute Gaming Realms’ Slingo Originals portfolio of games in New Jersey, USA.
Patrick Southon, Gaming Realms chief executive, said: "We are delighted to be extending our relationship with GVC Holdings, one of the world's largest sports betting and gaming groups. We believe that the Slingo game format has mass player appeal, so we are excited by the prospect of the game entering a number of new territories through the GVC partnership and gaining exposure to a large new player audience."
