Jigsaw Sudoku puzzles replace the rectangular bold-lined boxes in regular Sudoku with irregularly-shaped 'jigsaw' regions. Jigsaw Sudoku is also sometimes known as Irregular Sudoku, Jigdoku, Logi-5 or Logi-6.

How to solve Jigsaw Sudoku puzzles
In Jigsaw Sudoku the irregular jigsaw-regions that replace the 3-by-3 (or other size) box regions from Sudoku are always the same size. This means that in, for example, a 9x9 puzzle you must place 1-9 once each into every bold-lined jigsaw region, as well as the rows and columns. In all other respects the puzzle works in the same way, but this change in the region shapes introduces new twists into the logic required to solve the puzzle - and often makes it much harder for you to find the next move as a result!

Look at the solved puzzle on the left. In this 6x6 puzzle notice how there are 6 bold-lined jigsaw regions, each containing 1 to 6 exactly once.

Every Jigsaw Sudoku puzzle only ever has one possible solution, and it can always be reached via reasonable logical deduction. In other words, guessing is never required.

Jigsaw Sudoku puzzles on puzzlemix appear at a wide range of sizes and difficulties. Usually they are 6x6, 8x8 or 9x9, although sometimes they are 12x12. In each respective case you must place 1-6, 1-8, 1-9 or 1-12 once each into every row, column and bold-lined jigsaw shape.
