Tool to solve Sudoku16x16. Hexadoku is a variant of classical Sudoku, also called giant sudoku, of size 16 by 16, with inner squares of 4x4. It can be filled with letters of hexadecimal characters.

### How to fill the Hexadoku 16x16 grid?

One can do a copy/paste of type directly in cells (space for empty). Letters A-Z and digits 0-9 are accepted.

Example: Copy the content in the first cell 89 4 3 1 DA2 6 DA B E 5C 8 1CF 5 EB 6 4 32 AC 9 4 1 A 4 6 E7 8 E 6 5 7 0F4 6 7C 9 D87 E 6 5A 2 08 5 E F 45 2FA 8369 D A3720 F A D5 C 4 1D04 AF C E8 B C1  to get:

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

### How does the step by step works?

Software solves the 16*16 sudoku (hexadoku/hexasudoku) using logical deduction, just like an human would do and show each step of its progress.

The explanations are detailed and deducted for the content of rows, columns or blocks.

Sometimes no immediate logical solution can be found for a cell, the solver tries a value in the cell and continues until an inconsistency happens. If the solver find a problem it comes back to previous steps (these steps are not displayed). If there are none, then the solution is shown, there may be many possible solutions.
