I find it kind of interesting that the more rare a technique is, the less likely it's to be found in Sudoku puzzles: Easier techniques can solve about 70%, medium difficulty just over 10% and difficult about 5% of all Sudoku puzzles. About 90% of all Sudoku puzzles were solved with these techniques which is quite nice, but new Sudoku techniques will still be found after you know these.

Take the challenge and try how well you know advanced Sudoku techniques.
