Based on your post, she dislikes arcade, action and racing style games so avoid those genres. Look into puzzles and card.
Definitely check out Pyramid Solitaire: https://play.google.com/store/apps/details?id=com.king.pyramidsolitairesaga&hl=en_CA
I also highly recommend Klocki. It's chill and enjoyable: https://play.google.com/store/apps/details?id=com.klockigame.klocki
There's another one called Clocking. Same game as Klocki but free: https://play.google.com/store/apps/details?id=com.Toppin.DISASSEMBLEME
Honestly, you can't go wrong exploring puzzle and card genres. And depending on the game, casual genre will suit her needs too.
