Examples

You can specify input via a JSON file or a more human-readable text format. See the puzzles/ folder for some examples.

For example, here is one possible input puzzle:

* * * | 5 * 6 | * * * 
* * 4 | * * * | 8 * * 
* 9 * | 1 * 2 | * 6 * 
---------------------
9 * 8 | * * * | 3 * 2 
* * * | * 9 * | * * * 
1 * 2 | * * * | 4 * 7 
---------------------
* 2 * | 3 * 4 | * 8 * 
* * 7 | * * * | 9 * * 
* * * | 9 * 5 | * * *

If this file was saved in puzzle.txt, you can solve it with:

doku puzzle.txt

Which would print:

2 8 1 | 5 4 6 | 7 3 9 
6 5 4 | 7 3 9 | 8 2 1 
7 9 3 | 1 8 2 | 5 6 4 
---------------------
9 7 8 | 4 6 1 | 3 5 2 
4 3 5 | 2 9 7 | 6 1 8 
1 6 2 | 8 5 3 | 4 9 7 
---------------------
5 2 9 | 3 7 4 | 1 8 6 
3 1 7 | 6 2 8 | 9 4 5 
8 4 6 | 9 1 5 | 2 7 3
