I think the categories for the puzzles could be refurbished:
Lately I browsed through the category "Odd Shapes". There are things like MadTriad together with several cylinders and the octagonal prism.
My suggestions are:
-Make up a category "Other" under N-Sided where all puzzles with N flat sides (N<>4,6,8,12,14,20) move to, E.G. my avatar.
-Make up a category with "Cylinders" or "rounded sides" neighboring to Sphere.
-Reserve the "Odd Shapes" to things like the StaircaseCube.
What do you think?

I agree the odd shapes category has too many very different types of puzzle.

I also think it would be better to show the entire category instead of it being split into pages. I assume this restriction goes back to when we had 28k modems.
