NOT LOGICAL!!!!!!!!! holy shit people how many of these puzzles do i have to state the definition of logic...assumption that is correct based on symmetry....IS NOT LOGICAL....its guessing based on what your mind assumes to be correct, but because this puzzle can literally be solved dozens of ways....IT IS NOT LOGICAL!!!!!!!
I don't know what all the fuss is about. This puzzle can be solved completely using logic. (however, if you want to solve it quickly and get more points, you could solve it using symmetry and common sense for the pattern - I chose to forfeit the extra points and solved it in 8 minutes using logic alone!!!)
