Gray Insert "Checking your irregular hexadoku puzzle" :

You have four acceptable results:
• This grid has only one solution.
• This grid has several possible solutions.
• This grid is false, no possible solution.
• Input Error with equal numbers in row, colomn or area.

Rules:

The hexadoku is 16 X 16 squares instead of 9 X 9 squares. The solving techniques are identical to those of a classic sudoku.

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.

The hexadecimal system is a numeral system with a base of 16, using Arabic numerals to represent values 0-9 and the letters A-F for the other six. The hexadecimal is especially useful in computer science because it is much easier to map binary to hexadecimal than to decimal.

Browser:

We recommend you try Google Chrome, for its speed and its various features are very welcome when it comes to solving puzzles of 256 squares.
