According to Twitch, the game was also the biggest touchscreen eSport last year, with $350,000 in prize money around the world. During the winter championships, the competition drew over 1.5 million viewers on the streaming service. The deal means that Twitch will provide a dedicated broadcast team to cover Vainglory events and handle sponsorship and merchandise deals. The spring championships kick off today with registration for three-player teams competing for a total prize pool of $80,000.

With the new season comes new game options, including a new beta "Battle Royal" mode, along with a new hero, skin and "Halcyon Days" event. According to Twitch eSports director Nick Allen, the deal shows that mobile titles, once slagged by gamers, are on the upswing thanks to higher quality titles. "The eSports industry has been dominated by PC and console titles, but Vainglory is ushering in a new mobile games movement," he says.
