The deal enables the development of gaming content under the 'Britain's Got Talent' and 'The X Factor' brands.
The new BGTGames.com site has gone live ahead of this year's Britain's Got Talent series beginning this month.
The site also includes a bespoke Britain's Got Talent branded version of Gaming Realms' leading game, Slingo.
The launch of BGTGames.com is backed by a significant marketing campaign across terrestrial TV and digital platforms, which will start this month.
