Sutoku

Sutoku is a Japanese-style puzzle game that shares similarities with Sudoku. The objective of Sutoku is to fill a grid with numbers according to a set of rules. Unlike Sudoku, which typically uses a 9x9 grid divided into 3x3 subgrids, Sutoku puzzles can vary in size and the number of subgrids. The core mechanic involves logical deduction to determine the placement of numbers, ensuring that no number is repeated within a row, column, or defined region.

The rules for Sutoku are generally straightforward: each row, column, and specified region must contain a unique set of numbers, usually from 1 to the size of the grid. The complexity arises from the initial placement of given numbers, which serve as clues to solve the puzzle. Players must analyze these clues and use deductive reasoning to fill in the remaining empty cells. There are no mathematical calculations involved, only logical placement.

Sutoku puzzles can be found in various publications and online platforms, often alongside other logic puzzles. The variations in grid size and region shapes allow for a wide range of difficulty levels, catering to both beginners and experienced puzzle enthusiasts. The game's appeal lies in its blend of simplicity and intellectual challenge, providing a satisfying mental exercise.
