Tips for Solving Sudoku Puzzles

By Timothy E. Parker

Part of Brain Game For Dummies Cheat Sheet

When you’re working on a Sudoku puzzle you can throw vocabulary and factual knowledge out the window. Keys to solving Sudoku puzzles are logic and diligence along with these key strategies:

  • It’s harder than it looks! Even with the easiest puzzle, you won’t fill in a Sudoku grid in a matter of minutes.

  • Each puzzle has a unique answer; you can’t find multiple ways to solve it.

  • Start each puzzle by locating obvious, definite answers — those that you can solve simply by looking at what else falls within a particular row, column, and 3-x-3 box.

  • When you’ve exhausted the obvious answers, you need to find a systematic way to explore the less obvious (but still definite) answers.

  • Myriad advanced strategies exist. If you search for killer, advanced, or extreme Sudoku online, you’ll find countless websites that contain strategy suggestions for the toughest of puzzles.
