The Sudoku Puzzle Book series is available in the following difficulty levels: Easy, Medium, Hard, Very Hard and Extreme. All difficulty levels are available in the following formats: Sudoku, Jigsaw Sudoku, Sudoku-X and Jigsaw Sudoku-X In my classic Sudoku puzzles, the grid is 9 cells wide and 9 cells deep. The lines of squares running horizontally are called rows, and the lines running vertically are called columns. The grid is further divided by thicker lines into nine 3 X 3 square boxes. The aim of the puzzle is to fill the blank cells with the correct numbers. Each row, column and 3 X 3 box must end up containing all of the numbers from 1 to 9. Each number can only appear once in any row, column and 3 X 3 box. 250 Very Hard Sudoku Puzzles Handy 6 x 9 inch Book Layout Easy to read (2 Puzzles per Page) Advanced Solving Techniques Required Solutions Included How the Difficulty Levels of the Puzzles are Determined: Difficulty levels are determined by the complexity of the methods used to deduce the correct solution: Each level (Hard, Very Hard & Extreme) necessitates a mode of deduction which was not required in the previous level.

As with the "Easy" difficulty puzzles, advanced solving techniques are not required, and all puzzles can be solved by scanning rows, columns and 3 x 3 boxes to determine the correct numbers. Hard: The "Hard" difficulty level puzzles do require some advanced solving methods to be employed. These puzzles are more suited to those learning to use more complex deduction processes and moderately experienced Sudoku puzzle solvers. Very Hard:The "Very Hard" series is one step up from the "Hard" level, forcing the solver to use more complex deduction methods. This level is definitely one for the more experienced solvers and Sudoku fanatics. Extreme: As the difficulty level suggests, these puzzles are extremely difficult to complete. Unless you are an expert Sudoku solver, these puzzles may be too hard for you.
