Sudokuing

The game board consists of a 9x9 grid, divided into 9 smaller 3x3 squares. The game goal is to fill each square with numbers from 1 to 9, ensuring that every row, column, and small square contains each number exactly once.

• Fill in the remaining empty squares.
• Fill each 3x3 square with the numbers 1 to 9.
• Each row, column, and 3x3 box must contain the numbers 1 to 9, with no repetitions.

Sudoku is a game of logic and patience. With practice, you'll improve your pattern recognition and deduction skills, allowing you to solve even the most challenging puzzles. Happy Sudoku solving!

• Look for squares that have only one possible number based on the existing numbers in their row, column, and 3x3 box. These "unique candidates" can be filled in immediately, providing valuable clues for the rest of the puzzle.
• Use logical deduction to eliminate possibilities. Look for numbers that are already present in a row, column, or 3x3 box, and eliminate them as options for other empty squares within that unit. Repeat this process until you've narrowed down the possibilities.
• When you reach a point where no obvious moves can be made, try making an educated guess by selecting a square with two or three potential numbers. Follow the consequences of each choice, keeping track of any contradictions that arise. If you encounter a contradiction, backtrack and try the alternative number(s) for that square.
