Google-owned YouTube is internally testing a product for playing online games, the Wall Street Journal reported citing an email sent to Google employees.

The company invited its employees to begin testing the new YouTube product called 'Playables', the report said, adding that games available for testing included titles such as arcade game Stack Bounce.

The games can be played on YouTube's site on web browsers or via devices running Google's Android and Apple's iOS mobile systems, the report added.

Google did not respond to a Reuters' request for comment on the report.

Hosting online games on YouTube, which is a popular place for users to stream games and watch livestreamed game footage is part of CEO Neal Mohan's push into new areas of growth amid a slowdown in advertising spending, the WSJ report said.

Meanwhile, the streaming platform is also testing an AI-powered tool for creators to dub videos into other languages.
