Tool/Solver to resolve 12x12 Sudoku. Sudozen is a variant of classical Sudoku with 12 lines and 12 columns. Blocks are rectangular (3 by 4) but the principle remains the same.

One can do a copy-paste (space for empty) of type directly in cells.

Only letters A-Z and digits 0-9 are accepted (compatible 12x12 wordoku). Do not type values 10, 11 and 12 into the cells, use A, B and C, or 0, A and B for example.

Example: Copy and paste this content in the top first cell 5 913 C2 A B 8 16 B C 6 73 92 A3 8 6 7 72 A B 79C B6 1 3 23B4 5 71 C16 C3 B9B 83697 C4 C 3 AB9 564 BA782 to get the 12*12 sudoku grid :

How does the step by step works?

The program solves the Sudozen like a human would do (analysis of rows, columns and blocks) and explains each step of its progress.

Sometimes the only logical solution is to try a random number and see if the resolution is possible.
