Last time i flew I noticed the lady next to me was owning the Sudoku puzzle in the back of the Southwest Airlines magazine. I gave it my best but I can not for the life of me understand what I am supposed to do. The instructions simply say “Use logic to fill in the nine squares” – I tried for 40 minuted to understand the “logic” to filling in the blanks, it just served to make me feel inadequate and dumb. I would prefer hang man or M.A.S.H please.
