I have only just started doing Sudoku & Super Sudoku puzzles, but these puzzles seem to take well over the normal time you would expect with circa 3 times as many squares. It is very hard to visualise possibilities when the rows, columns & squares are bigger. Experienced Sudoku solvers I have known can take hours doing one of these puzzles.
In fact, I found them impossible until I spent some time developing a very handy spreadsheet for myself which provides a lot of guidance & can check entries against the solution, if one is available. Now I'm addicted.
As far as I know, this & volume 2 are the only books on the market dedicated to the larger puzzles and, if you want a change from the norm, I would recommend them.
