If you’re not familiar with Humble Bundle, they have offer bundles of games, often older games, and give a cut to the developer, and a cut to charity. Usually there’s a base bundle and then you get a bonus for paying above average, or above a specific threshold.
This is actually my first “Mobile” bundle, which basically means Android games. I’ve been working through testing the games for compatibility with the Fire OS platform and updating this post as I’ve gone. Only one game (Wayward Souls) specifically requires Google Play services, so the rest work on Fire OS, either on tablet or Fire TV.
Amazon shows compatible with 1st gen Fire TV and 2nd Gen Fire TV Stick. Seems fine with my 2nd Gen Fire TV stick. Oddly enough, doesn’t show compatible with Fire tablets.
Tested on 2nd Gen Fire TV
Evoland (not available on Amazon, $5 on Google Play)
