Jigsoku. Jigsaw Sudoku.

Jigsaw Sudoku with colorful irregular regions. Every puzzle is unique — master new strategies with smart hints, daily challenges, and campaign mode.

Jigsoku is Jigsaw Sudoku — where the familiar 3×3 boxes are gone, replaced by nine colourful, irregularly shaped regions that look like a jigsaw puzzle. Every region still holds digits 1–9, and so does every row and column. But the irregular shapes change everything about how you think and solve.

Standard Sudoku logic only gets you so far. The wildcard shapes force new strategies, new spatial reasoning, and a completely fresh challenge — even for experienced solvers.
