For me, the clergy and chess pieces were really easy (even with the red herring of bishop as clergy.) The others were challenging, but I was able to see the link for bars when given the grouping, and I could plausibly have found the other link.

Not everyone is religious, @David. That one was impossible. Literally... Unplayable...

Never heard of a pry bar, so that spoilt it for me

Love the false group of the birds, took me a while to try the chess pieces cause I was so sure rook was a red herring there
