Google: Try Android Games Before Downloading Them
This is Google Play Instant.
This has also been integrated into the Play Games app in the Arcade section.
I experienced this with Clash Royale, and loading was pretty fast.

The Instant App screen appears for less than two seconds; nor gave time to print the first time.
This technology is still in closed beta for developers; if you are interested, complete this form.
They also do not require installation; you’re able to try out some of themhere.

This is not web apps; they run natively and work only on Android with Google Play Services.
The instant version of a game needs to weigh less than 10 MB.
To turn this feature on or off, go to options> Google> Instant Apps.

It will only appear if your phone is compatible.
