Sudoku  \(数独 sūdoku, digit\-single\) \- is a logic\-based, combinatorial number\-placement puzzle\. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid \(also called "boxes", "blocks", or "regions"\) contains all of the digits from 1 to 9\.   The rules of Jigsaw Sudoku are similar to standard Sudoku, since you must place each of the numbers 1 to 9 \(or 1 to whatever the size of the puzzle is\) into each of the rows and columns\. However whereas standard Sudoku also has rectangular boxes that must each contain every number, in Jigsaw Sudoku these boxes are replaced by different bold\-lined shapes that must each contain every number instead\. ©     100 challenging Sudoku Jigsaw puzzles    Level's progress save    Beautiful minimalist design, multiple pleasing color themes    10 ambient relaxing soundtracks    Steam Achievements    Trading Cards, Badge, Emoticons and Backgrounds \(Coming soon\)    Steam Cloud support    Enjoy on Windows, Mac and Linux
