Irregular jigsaw hexadoku puzzle to print
Our irregular hexadoku puzzles are 16 X 16 fiendish sudoku. Instead of nine 3 X 3 square areas, you have 16 areas of irregular shapes each with 16 squares. The rules are the same as for a classic sudoku. You need to find by deduction 16 different digits by row, column and area.
To reduce the size of the grid on the screen and to facilitate entering values, the possibilities are represented here by the following hexadecimal digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F.
You have 6,000 puzzles presented in two forms and three levels.

Levels to print:
• Puzzles "Beginner" are fully resolvable by "Inclusion" while accepting other methods.
• Puzzles "Confirmed" are fully resolvable by "Inclusion" and "Exclusion" while admitting to other methods.
• Puzzles "Expert" are solvable by "Inclusion", "Exclusion" and "Pairs exclusive".
For more details on these three methods for resolution, identical to the regular sudoku, see: General help.
Symmetrical and asymmetrical puzzles:
An irregular 16 x 16 puzzle, is symmetrical when the squares that compose it are arranged equally around the four central squares known as the center of symmetry. This is only esthetic and does not change the resolution mode of the grid. Indeed it is the puzzle that is symmetrical and not the solution. However, the advantage of non-symmetrical puzzles is that, having one less constraint, they allow the elaboration of more difficult problems.
