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.
