What are your go-to phone games/apps for distraction/keeping yourself occupied?

I play water sort and mahjong on my phone. What are your go tos ? I think I need better ones as I go into my visit with the in laws, it helps me keep quiet when I shouldn’t say things, and keep myself less fidgety during movies

EDit : there's so many good suggestions already, I want to say thank you I'm going to look carefully at all of the ones that you all have mentioned!
