Do you play any games on your smartphone? I'm looking for single player ones to kill some time when waiting for the bus. Ideally they should work without an internet connection, so I can disable network access for that app and play without ads.
I'm currently playing Words of Wonder, but it gets repetitive after a while.
The best mobile games are the games that aren't actually mobile games but now you can play them on your phone. Old pokemon games on emulator, minecraft, etc
