Roblox Corp is partnering with Alphabet Inc's Google to offer ads that encourage player engagement, marking a significant step in the video-game platform's push to generate more revenue from advertising.

The company boasts that the new Rewarded Video ads show higher engagement than regular advertising, with a completion rate between 80-90%. Roblox says users who trialled the system "saw the value" in watching ads for rewards such as power-ups or in-game currency.
