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 (no numbers 10,11,12,13,14,15,16, replace them with A, B, C, D, E, F if necessary).

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?

The Sudoku 16*16 solver solves the hexadoku / hexasudoku /hexa-wordoku grid by following logical deductions (similar to a human) and displays the steps 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.
