Tips and Tricks
Every Sudoku solver sometimes reaches a point when he or she has no idea what to do next, so various daredevil solutions get considered. It is quite enough to overlook one number, blocking pair or any other combination and one's solving may easily take a few hours! If you find out after hours of hard work that the solution has been right under your nose the whole time and that you should have used a simple technique, you definitely have reason to laugh (or to get angry).
Our section of advice and interesting ideas not only analyses examples (these analyses often help you understand more complex techniques better than any complex explanations) with nicely described logical solving steps, but it also offers some, more-or-less, interesting observations we love to share with you.
