I’m looking for Android games that are designed to be played vertically (portrait mode). Could be casual, action, puzzle, roguelike, or anything really. Best if it can be played one-handed.
Paid or not doesn’t matter.
Feel free to exclude the pay-to-win crowd. Still, name 'em if you feel you have an excellent exception.

‘Antiyoy’ is a simple strategy game, fit well for shortish sessions. Free and with minimal permissions. Iirc ‘Antiyoy Classic’ is offline-only, while the regular one has multiplayer.
‘Diplicity’ is a multiplayer-only (afaik) strategy like ‘Risk’, but with zero element of chance, only diplomacy. However the games can be rather slow, from what I’ve heard.
‘Fabularium’ is an app for running text-adventure games — one of many such apps, but I like it because it supports modern game formats. You’ll need to download the games themselves elsewhere, mainly from ifdb.org — there are a lot of games, some of them with quite novel mechanics.
‘Hocus’ is a geometrical puzzle with impossible shapes. Iirc additional levels are paid.
I’ve heard that ‘Mindustry’ is a good open-source clone of ‘Factorio’, but idk how it plays on a phone screen.
