Relaxing Sudoku and Futushiki
Sudoku is a classic logic-based number puzzle that challenges players to fill a 9x9 grid with digits from 1 to 9. The grid is divided into smaller 3x3 subgrids, called "regions." The objective is to place numbers in such a way that each row, column, and region contains all digits from 1 to 9 without repeating any number. The puzzle starts with some numbers already filled in, providing clues to help deduce the correct placements for the empty cells. Sudoku requires no math skills—just patience, pattern recognition, and logical reasoning. It’s popular worldwide as a brain-teasing pastime, available in newspapers, books, and digital formats. Whether played casually or competitively, Sudoku offers a satisfying mental workout for all ages.
