What should I do if I'm not familiar with the game and can't play it well?

It's okay if you can't play well for games! Like riding a bicycle for the first time, by taking on a challenge even though you can't do it, your brain will be stimulated and you will be able to practice binocular vision, and you will gradually get used to the game and be able to play it. Please refer to the troubleshooting section for each game for tips on what to say to the patient in each game and for the patient to play.
