Solve a Sudozen grid
Answers to Questions (FAQ)
What is a Sudozen? (Definition)
A sudozen is a modified Sudoku grid of 12x12 size (dozen means twelve). The blocks inside the grid are no longer square but rectangular.
dCode offers a solver for irregular Sudoku if the grid is a different size or format.
How to fill the Sudozen grid?
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:
| 5 | ␣ | 9 | 1 | 3 | ␣ | ␣ | C | 2 | ␣ | A | ␣ |
| ␣ | ␣ | ␣ | B | ␣ | ␣ | ␣ | ␣ | ␣ | ␣ | ␣ | 8 |
| ␣ | ␣ | ␣ | ␣ | ␣ | ␣ | 1 | 6 | ␣ | ␣ | ␣ | B |
| ␣ | C | ␣ | 6 | ␣ | 7 | 3 | ␣ | 9 | 2 | ␣ | ␣ |
| A | 3 | ␣ | ␣ | 8 | ␣ | ␣ | ␣ | 6 | ␣ | 7 | ␣ |
| ␣ | 7 | 2 | ␣ | A | ␣ | ␣ | ␣ | B | ␣ | ␣ | ␣ |
| 7 | 9 | C | ␣ | B | 6 | ␣ | 1 | ␣ | 3 | ␣ | 2 |
| 3 | B | 4 | ␣ | ␣ | 5 | ␣ | 7 | 1 | ␣ | ␣ | C |
| 1 | 6 | ␣ | ␣ | ␣ | ␣ | C | 3 | ␣ | ␣ | B | 9 |
| B | ␣ | 8 | 3 | 6 | 9 | 7 | ␣ | C | 4 | ␣ | ␣ |
| ␣ | ␣ | ␣ | C | ␣ | 3 | ␣ | ␣ | A | B | 9 | ␣ |
| ␣ | 5 | 6 | 4 | ␣ | ␣ | B | A | 7 | 8 | 2 | ␣ |
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.
