I loved Tomb Raider Go on Android, superbrother sword and sorcery, that Reigns game and a normal lost phone. And Father and son https://play.google.com/store/apps/details?id=it.tuomuseo.fa...

I am not claiming it's the best format for these games but playing it on my phone was easy and great.

There's also a solo card game, the name escapes me, I spent hours on it (edit: https://play.google.com/store/apps/details?id=com.tinytoucht...).

My phone is the most available device and games are cheaper than Switch games if easy-to-pick-up is a criteria.

Anyway, it depends on what you like :).

(I didn't like an old man's tale at all, I thought it was ripoff).

edit: if some people on HN get my preferences from this post I am all ears for mobile game suggestions :).
