nice grid with a few red herrings

Forehand and backhand are interchangeable. No unique solution.

"Forehand and backhand are interchangeable."

How so? Backhand fits in the row that Forehand is in, but as best I can tell Forehand doesn't fit in the row that Backhand is in. Please elaborate.

Eady, but fun.

Crocodilly is correct, this grid doesn't work unfortunately. Of course Forehand and Backhand are interchangeable William, how can you not tell? They're both tennis shots and they both contain the same body part. Why wouldn't they be?

I've just now noticed where you've gotten confused. Did you forget that "Hand" is also a body part?

"Did you forget that "Hand" is also a body part?"

I see what you mean, and you are absolutely correct. There is a whole separate category of "CONTAINS a bodypart", that I did not think about, when I made my category. I never do "contains"-categories, but only beginnings or ends, so I simply didn't think about it.

My bad! I apologise.

Said Computer, not Windows. Thought that would be close enough. Great grid though 😁
