with various aids.

 0 1 2 3 4 5 6 7 8 9 A B C D E F

Rules:

A hexadoku is a 16x16 sudoku puzzle 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.

Hexadecimal is a system that uses 16 digits: The numbers from 0 to 9 and the letters from "A" to "F".
Hexadecimal is particularly used in computer science. Indeed the hexadecimal allows easy conversion into binary that uses only two digits: the "0" and the "1".
