Apple said in August that it allows cloud gaming services on the App Store, but each individual game must be submitted for review by the App Store team. So far, submitting hundreds of games to the App Store does not seem to be something that any cloud game service developer wants to do. These cloud game services have chosen to access through the Web.
Google is developing a web version of Stadia, which will run on Safari and will undergo public beta testing in the coming weeks.
Google launched Stadia a year ago, allowing subscribers to play cloud-based games on compatible laptops, PCs, Macs, phones, and tablets. Stadia requires a network connection speed of 10Mb/s or higher. Google also offers Stadia Pro at a price of $10 per month, and users can use some free games and higher resolution streaming rates.
According to Google, more than 80 games have been added to Stadia last year, and Google will also provide free content for non-subscribers.
