It's best known for casual hidden object games and casino titles, but Big Fish is keen to demonstrate it can be successful in other genres.

That's the thinking behind its announcement that it will be publishing the debut game from US start-up Boss Fight.

Created by the old Zynga Dallas team, including veterans from Halo Wars. Age of Empires and Castleville , Boss Fight is making as-yet unannounced midcore free-to-play experience.

Underpinning the deal is Big Fish's veep of studios Chris Williams, who's been leading Big Fish's F2P charge over the past 18 months.

"Big Fish launched 5 F2P games in 2013 and more than half its mobile revenue stemmed from those products," he revealed.

"In 2014, the company will be focused on launching hit F2P games - some in genres that may be unexpected. The game with Boss Fight is one of those surprises."

David Rippy, Boss Fight's CEO added, "We were impressed with Big Fish's ability to take Big Fish Casino and scale it worldwide to the #1 grossing app in the casino genre."
