Dublin-based game developer Digit has been acquired by Los Angeles-based Scopely for an undisclosed sum.
Digit, which employes around 70 people, was founded in 2012 and specialises in mobile games.
Its recent collaboration with Scopely, based on the Star Trek franchise, generated $50m in revenue in the first four months of its availability.
Scopely was already a minority shareholder in Digit, with other backers including Enterprise Ireland, Delta Partners and ACT Venture.
Investors in Scopely itself include actor Arnold Schwarzenegger and co-founder of Beats by Dre and Interscope Records Jimmy Iovine.
The studio recently recorded annual revenues of $400m, thanks to the success of games based on the Looney Tunes and WWE brands as well as the Wheel of Fortune gameshow.
Digit founder and CEO Richard Barnwell will continue to manage the Dublin operations following the acquisition.
