Google Stadia, the video game streaming service that turned one year old this week, is coming to iOS devices soon.

Until now it has only been available on Android phones and tablets, as well as through computer web browsers, and on televisions connected to Google's Chromecast Ultra streaming dongle.

But creating a Stadia app for iPhone and iPad has been tricky for Google, due to Apple's App Store restrictions, which would require every game available through Stadia to be submitted for approval. With over 80 games currently on Stadia, and 135 to be available before the end of the year, seeking approval for every title isn't practical.

So instead of making a Stadia app for iOS, Google will run its gaming service through the web browser.

Google says public testing of this will begin "several weeks from now," says Polygon, whose report was tweeted by Google's Stadia Twitter account, seemingly confirming the news. Stadia said: "As you might have heard, the first phase of iOS support is coming to Stadia! Stay tuned for more to come."

Stadia is free to play for all Google account holders. Some games are also available for free on the platform, while others have to be bought individually for their regular price, and some come included in the Stadia Pro tier, which costs $10 a month and also gives gamers access to a higher resolution experience with improved audio.

Those who want to play on a television need to connect a Chromecast Ultra streaming dongle, and Google also sells a Stadia-branded game controller, although other gamepads can be used too.

Google won't yet say how many people use Stadia, but that number is likely to increase markedly in December, as pre-ordering the highly-anticipated (and delayed) Cyberpunk 2077 through Stadia, and before December 10, includes a free Chromecast Ultra and Stadia controller.
