That might just be over-egging the 'non-unique' pudding.

This grid doesn't work, I'm afraid. A good idea but if you have more than one the same it means that someone could choose the right word but not in the box from the group and be marked wrong. 2 the same makes it non- unique ie unfair. Lots the same creates countless permutations and makes the grid nearly impossible. You'd have to try every entry of racket, net etc. to get a group. Some nice ideas, though, it's just about getting familiar with the site and how things work, so do keep at it! :)
