Or Jetris for that matter? I’m kind of surprised that there isn’t some sort of OS Tetris clone on F-Droid (TTTris, I think, is still there but it’s incompatible with my phone and hasn’t been updated in 14 years!).

I saved the apk for Jetris after it disappeared from F-Droid, but can’t install it on my device. I’m not a programmer, but is there anything I can do to the code to get it to work?
