About the game
Jigsaw Sudoku keeps the classic rule, each number once in every row and column, but swaps the neat square boxes for irregular pieces that snake across the grid. Those odd shapes change everything: a piece that bends around a corner shares cells with rows and columns in unusual ways, so new deductions appear where a normal sudoku would have none. Puzzles start on a tiny 4x4 grid and grow to full 9x9 boards over thirty levels, and every one has a single answer you can reach by reasoning alone, without guessing.
The twist is digit-first play. Choose a number on the pad and the board immediately tints every cell where it could still go. If a row, column or piece has only one such cell left, that cell glows gold, which is exactly the move a sharp solver looks for. Stuck? A hint places one number and shows the row, column or piece that forced it. Stars reward solving with few hints.
