Most helpful critical review
Not the easiest puzzles I've tried.
on 1 January 2015
My own fault for not reading description fully, but was expecting the usual 200+ puzzles. Plus, they seem to get progressively harder as I worked through the book. So much so, that I could not even start some of them. Main legitimate gripe, however, is the fact that the answers for No 94, are not, they are the answers for No 88.
