Recommendations for easy games for someone learning VO for the first time

I am a sighted speech language pathologist and new to learning how to use VO on iPhone. I am working with a client who is newly blind and wanting to use his phone more. He is interested in learning VO compatible games and has already mastered Dice World and Pirate Poker as well as using a local news app (KSL) to listen to news stories. We are both beginners and would welcome any recommendations from more seasoned users. Thanks you so much!
