On the scale of 1-10 This is a 100

So far out of the park, this Sudoku takes you to new level after level after level. If learning is what you love, do not look further. This is your game. If you just want to pass the time, this will give you game after game at exactly your level. But for those who live to learn, this is an extravaganza of Sudoku techniques and easy tips, graded by difficulty and techniques. A rich harvest. Cant imagine the person that created this. So smart, so giving. I would guess that youll never find the like of this in any other field, its that good.
