This is a fun logic puzzle, a bit harder than most of its ilk. I made a table for it to simplify finding the solution, putting “x” and “o” in the cells (easier to keep straight than sticky notes!): http://imgur.com/mgvyI

I completed Eintein’s riddle (http://www.manbottle.com/trivia/einstein_s_riddle) in about an hour.
I’ve added a photo of my working to show I wasn’t cheating. 🙂 The top row is every pet/drink/smoke so I could score them off as needed; the middle row is my actual answers (left column is answer, right column is clue number); and the bottom row is just some extra bits that can be ignored.
