What games can I play with my grandma to help her stay mentally stimulated?

She's not really interested in playing games by herself and she'll end up just sitting there and getting depressed,
And has a tendency to think games are a waist of time even it's just for fun 🥲

I've hanging out with her a lot lately but I'm trying to get her into some sort of hobby or something that might keep her mind mentally sharp, active, occupied etc?
Maybe something we can do together?
