Sudoku is a popular logic-based puzzle game that challenges players to fill a 9x9 grid with numbers from 1 to 9. The grid is divided into nine 3x3 subgrids, known as blocks. The goal is to fill each row, column, and block with the numbers 1 to 9 without repeating any number within the same row, column, or block.

Solving Techniques

Sudoku puzzles can be solved using a combination of logic and deduction. Here are some common techniques:

* Scanning: Examine each row, column, and block to identify which numbers are already present. This will help narrow down the possible numbers that can be placed in the remaining empty cells.

* Elimination: Determine which numbers cannot be placed in a particular cell by considering the numbers already present in the same row, column, and block.

* Hidden Singles: If a number is the only possible number that can be placed in a cell, it is called a hidden single. Identifying hidden singles can help you fill in cells quickly.

* Naked Pairs: If two cells in the same row, column, or block contain the same two possible numbers, those numbers cannot appear in any other cells within that unit. This allows you to eliminate those numbers from the other cells.

* Trial and Error: Sometimes, you may need to guess and check to solve a puzzle. Make an educated guess and fill in a cell. If the guess leads to a contradiction, you can backtrack and try a different number.

* Improved Cognitive Function: Sudoku requires players to use logical reasoning, problem-solving skills, and spatial awareness. Solving puzzles can help improve memory, attention, and concentration.
