The Second Best Book of Sudoku Strategy: Using inductive reasoning to solve difficult puzzles mentally (English Edition)

Put aside Swordfish, XY-Wings, Squirm-Bags, color coding and other deductive tools.

Deductive approaches are like the guy who tries to find a girlfriend by kissing every girl in town until he finds one who doesn't slap him.

Stop spending your time kissing frogs! With inductive reasoning, you focus your attention on likely solutions. The results may take a little longer, but are much more gratifying and the process does more to sharpen your reasoning skills!

If you can remember four or five numbers for fifteen seconds, you can begin using these techniques.
