Mobile Streams partners with IGS to launch Battleriff

Mobile Streams plc and International Gaming Systems AB (IGS) are delighted to announce they have extended their partnership to launch Battleriff, one of the world's leading global gaming platforms, on www.mobilegaming.com

Battleriff has hosted over 3,500 Esports competitions (tournaments/leagues). Some of the most successful ones were the Battleriff Pro League and Invitational Tournaments for Hearthstone. The Battleriff Pro League was run under a licence with Activision Blizzard, awarding top participants an entry into Blizzards top tier Masters Tour competitions. The Invitational Tournaments featured many of the best players in the world and allow up and coming players to have a chance at qualifying and playing against the Pro players. Their website can be found at www.battleriff.com .

This partnership will allow the Company to deliver future Esports tournaments via Battleriff under its IGS partnership deal previously announced on 13 January 2022.  This represents the next step in the transformation of the Company into a leading global Esports and content provider and will open up a number of additional opportunities to sell further products to its global audience of over 800 million people. These opportunities will include, but are not limited to:  Licensed NFT content, branded merchandise and Skins trading.
