This method is very thorough and if you follow it exactly, you will be able to solve an easy sudoku puzzle. However, it requires a lot of time to write down every possibility in every square. I think it might be overkill for an easy puzzle. Most easy sudokus can be solved just by looking. Here's a video that shows you how to solve easy sudoku puzzles.

Certainly a decent way to solve simple puzzles, but make no mistake - solving one sudoku puzzle does not mean solving them all. The above Sudoku puzzle is classified as easy; I can finish it in under a minute without even writing down possibilities.This basic elimination method is generally the last thing you would be doing for intermediate and advanced puzzles. The hardest Sudoku puzzles require a good amount of logical thinking, observation, and occasionally memory.I'd be more than happy to create an advanced puzzle for anyone interested to see if the above method can even fill up a single column, row, or box.

in step 9, you have 3 written in twice. You have 8 circled but 4 eights that weren't erased.

I'm new to Sudoku. The tip about the circles, vertical and horizontal bars is a great help. Thanks!

I appreciate all of your work, but this makes the task way more complicated now. Plus, this isn't a tip for playing. Its just another kind of cheating, right?
