Does anyone know how frequently circle games have been used?

Such as the game in PT41 G4. I finished all the other games in my homework in less than 8 minutes with right answers. This game took me about 30 minutes, and I still got 2 wrong. If I had adhered to my time limit, I would have gotten 4 wrong between incorrect answer and blank answers that I would have had to guess on.

Do these types of games happen often?

I'm trying to figure out whether I need to bother to improve on this of focus my efforts elsewhere.

They're pretty rare. It's definitely better to focus your time on mastering the more common types, then push into non-standard versions of those, and then handle some miscellaneous game types like the circle games.
