Frequently Asked Questions

Does every Jigsaw Sudoku puzzle use the same region shapes?

No — the irregular regions are different in every puzzle. That variability is what makes Jigsaw feel fresh compared to classic Sudoku.

Can a Jigsaw region span multiple rows and columns?

Yes — each region just needs to be a connected group of exactly 9 cells. They can stretch into any irregular shape.
