I noticed that a lot of people don't know how to solve Sudoku puzzles because whenever I was in a public place waiting (Lobby) I would look for the Sudoku puzzles in newspapers to keep myself busy. If the newspaper was used by someone else, I would ask the person if they are planning to solve the Sudoku puzzle, surprisingly almost every time they would say that they don't know how to solve the puzzles, so they didn't mind giving me that section. I often got asked how I was able to solve Sudoku puzzles and I was always eager to teach those that were interested and wanted to learn how to solve Sudoku puzzles, after a tutorial with me they would walked away with a new understating and appreciation for the fun pastime of Sudoku puzzles.
