Jigsoku. Jigsaw Sudoku.

Jigsoku is jigsaw sudoku — the familiar 3×3 boxes are gone, replaced by nine colourful irregularly-shaped regions that look like jigsaw pieces. Each region still contains the numbers 1–9, as 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.
