Sudoku
Other
Sudoku is a logic-based number puzzle played on a 9x9 grid divided into 3x3 subgrids, where players fill in digits 1-9 so that each row, column, and subgrid contains no repeats. It requires deductive reasoning and pattern recognition rather than math skills, making it popular in newspapers and puzzle apps worldwide. Enthusiasts enjoy it as a mental exercise that sharpens concentration and logical thinking through progressively harder difficulty levels.
