At the Game Developers conference in 2018, which takes place in San Francisco, Google announced a revamped Android app that allows you to run them without installing to your device – Google Play Instant.
To try out the new feature is already possible on some games, for example Clash Royale, Saga 2, Bubble Witch 3 Saga, Mighty Battles.
I note that Android Instant Apps Google introduced in 2016. In 2017, have the opportunity to run some applications without installation, and the developers got access to the SDK Instant Android Apps. Now the system was rebranded as Google Play and supports Instant games.
This technology requires a smartphone with Android 5.0 Lollipop or higher. Google hopes that game developers will begin to post on their websites a link to such demo versions of games, and users will publish invitations in social networks. Google Play Instant is still in beta testing, but it will become available to everyone in the coming months.
