Using a progressive web app (PWA) that people can add to their homescreens like a native app, makes the gaming experience better. The site will let you play simple web games like Solitaire and match-threes and stream graphically intensive titles like racing games. Facebook's games use Facebook Pay for in-game purchases. They said that Apple's requirement for each cloud game to have its own page, go through review, and appear in search listings defeats the purpose of cloud gaming, therefor they went with a PWA. Amazon and Microsoft have also released PWAs for their cloud gaming services to get around the App Store policy.
A major problem Facebook has with this approach is that per Apple's rules, they aren't allowed to steer their regular app users to websites featuring purchasing mechanisms that aren't Apple's. So it's unclear how people will find this new Facebook Gaming PWA. Link
