Question Games on mi band 4?

[Migood]

So sometime ago I saw someone post a game for mi band 3 which was blackjack. I think they used macrodroid. Am no talking flappy bird or some other games. Like simple game which can be made by notification feature of the band. But i mean if flappy bird can run even with 2 fps or any other game, i wouldn't mind, you know, just saying. So help me out here.
