The “Easy” and “Medium” Difficulty levels require no advance solving techniques, however, in the “Easy” level, there will always be one or more cells that can be filled-in, whereas, in the Medium level there is sometimes only one cell that can be filled-in at any one time Easy: Ideal for beginners or those that simply want a very easy to solve Jigsaw Sudoku puzzle. No Advanced solving techniques required. Medium: A little more challenging than the "Easy" difficulty level. You may have to check a lot of rows, columns and irregular shapes before finding a cell that can be filled in. As with the "Easy" difficulty puzzles, advanced solving techniques are not required. Hard: The "Hard" difficulty level puzzles may require some basic advanced solving methods to be employed. These puzzles are more suited to those learning to use slightly more complex deduction processes and moderately experienced Jigsaw 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 the Jigsaw Sudoku fanatic. Extreme: As the difficulty level suggests, these puzzles are extremely difficult to complete. Unless you are an expert Jigsaw Sudoku solver, these puzzles may be too hard for you to complete.
