Ask Dr. Sudoku #1 – That 1/3/13 TomTom?

First in a series with puzzle solving tips. This time, TomTom solving tips for last week’s hard Thursday puzzle.

People always ask me how to solve puzzles and fast. My first answer is practice, practice, practice! My second is notation, notation, notation! After that, I say learn how to construct interesting puzzles and run through more involved logical deductions than most puzzles tend to have. In this column I intend to dissect some of our Grandmaster Puzzles with such interesting properties and at the same time reveal ways I look at puzzle styles that might help out in the future. This week’s topic is the Thursday TomTom, advertised at medium-hard difficulty, that few solvers beat in an expected time. While it shouldn’t need saying, SPOILERS AHEAD!

Editorial note: If this is the third TomTom you’ve ever seen (just trying to solve these puzzles this week), please do not attempt it. Go through a couple of my earlier examples in the “Thomas Snyder Outdoes the NYT KenKen” series instead. This is a very difficult “Saturday” puzzle in line with the hardest content of my old blog. Next week I’ll return with much easier puzzles in two new styles on Monday/Tuesday.
