Happy hebdomidaire grapple fans!!
In an effort to get Stiv to have to think for more than two minutes - I've drawn a puzzle from the " Spares" category, which is the equivalent of pulling that old unlabelled "rum" out of the drinks cabinet. In both cases a "Do Not Use" sticker lies intriguingly on the shelf.
Anyway, usual rules apply - each circle represents some(as yet) unknown category). Each tile belongs to at least one category. Your task is to find out which tiles belong where and why?
