Synova Capital LLP made an investment in London-based video games developer and publisher Mediatonic Ltd.
The private equity firm did not disclose the amount of the investment but said that it was "significant."
The fresh capital is expected to help Mediatonic invest in strategic partnerships, develop its original games and publish niche games from third-party developers.
Mediatonic has launched more than 100 games since it was co-founded in 2005 by Dave Bailey and Paul Croft.
