More Interesting Strategies
The puzzle shown to the right starts you with 24 tiles filled in. The solution I present begins, as most Sudoku puzzles do, with a few very basic steps. However, after doing so many of these in Example 1, 2 and 3, I decided to just skip to showing some more interesting methods where I could, regardless of whether simpler methods were available at the time. In fact, I find most Sudoku puzzles I solve are mostly done with the basic methods and only a few steps require much thinking. So, please note that the more interesting steps are not always the simplest next step available. Rather, they are chosen to illustrate strategies not in the first three puzzles.
