On the Challenge tab of the personal statistics is a Fizzy D/T Grid. Is there a published challenge for that?

Question

Is this just interesting information?   I was surprised to see that I have 80 of the 81 blocks filled.

Comments

I suggested that it was added just for fun! As far as I know there ain't a challenge like that and it is not allowed to make one - but it is still fun to check out how far you are and go for the goal to complete it though still just for fun - and because you can!

Answer 1

This is generally considered not to be allowed.

There is no way to tell if a cache is a challenge cache without looking at the cache title and that is a prohibited field.

Answer 2

I have not seen a challenge cache that has only challenge caches to complete a fizzy.  Could be that I just was not able to find it.  Closet I see are fizzy challenges with unknown caches only, for example:
