NFL Clash and NBA Clash developer Nifty Games has raised $38 million to build out a slate of mobile-first sports titles that leverage high-profile licenses.

The cash comprises $26 million in Series B funding and $12 million in connected debt financing, and takes Nifty's lifetime funding total to over $50 million.

The U.S. company said the funds will be used to expand its sports game roster and make fresh hires so it can create new titles using some of "the world's largest sports licenses."

"We’ve purpose-built Nifty Games to deliver a new slate of sports games for mobile gamers worldwide," said Nifty chief exec Jon Middleton. "We’re proud of the team we’ve assembled, our incredible partnerships with the NFL, NFLPA, NBA, and the NBPA, as well as our family of financial backers committed to seeing Nifty Games win big."

The news comes just over a year after Nifty opened its first internal development studio, Nifty Games Chicago, under the leadership of former Reliance Entertainment production VP, David Michicich.
