Google has announced Play Pass, a subscription service for Android devices that gives users unlimited access to a library of more than 350 games and apps for a monthly fee, with the selection on offer changing over time.

The announcement comes a few days after Apple Arcade was officially launched for iPhones. But where Arcade focuses primarily on new and exclusive games, Play Pass appears to prioritise more established titles. As part of the announcement Google highlighted games including Monument Valley 2, Limbo, Mini Metro, Stardew Valley, Terraria and Star Wars: Knights of the Old Republic. Play Pass will include non-game apps as well, such as AccuWeather.

The service is launching in the US this week, according to a Google blog post, but Australian availability was not announced beyond saying Play Pass would come to "additional countries" soon.

Like Apple Arcade, Google Play Pass will cost $US4.99 per month in the US (Apple Arcade goes for $7.99 per month in Australia), and provides access for a family group of six individual users. Yet while Play Pass only offers a 10-day free trial, Google is offering early adopters 12 months of the service at $US1.99 per month for a limited time.
