Irregular Sudoku NxN (called Jigsaw or Chaos) is identical to a classic sudoku, except for the blocks that are no longer regular square elements, but polyominoes that form a kind of jigsaw puzzle.
Indicates cells values one by one (it is also possible to make a copy-paste with space as empty cell) as in a classic sudoku.
Only letters or digits are allowed.
Blocks of 9 cells can be selected within predefined examples under the grid or indicated manually by clicking on borders.
Example: A 9x9 grid (copy/paste) forms nonominos
97 1 5 5 9 2 18 4 8 7 26 92 3 6 2 9 19 457 to get:
For larger grids, the solver only accepts one character per cell, so use letters.
Example: Write A for 10, B for 11 etc.
Software solves the Sudoku, similarly to an human, and display each step of its progress to understand without explaining.
