I remember that years ago when the android phones started there was a app for flash games....I don't remember the name the app (and maybe this app does not run in current android phones)
There was a browser-streaming app that would play them remotely, can't remember what it was called.
There was an official plugin by Adobe on Android but it was awful, I remember watching them showcase it at a conference it was tragic even with their handpicked and simple example.
Then there was a transpiler that produced native apps from Flash, this was actually pretty good but Apple then banned transpiling which killed its viability entirely, six months later they un-banned transpiling but the damage was done.
But on the plus side, Apple got to monopolize transaction fees in Flash games like Farmville for nearly two decades!
Now thanks to https://f-droid.org/es/packages/rs.ruffle/ (it has high % compatibility but it is ok) another we have again a handful flash games in the phone.
