How to Play
Sudoku is a logic-based number placement puzzle. You don’t need to be a math genius to win—you just need a keen eye and a bit of patience!
The Goal
Fill the grid so that every row, every column, and every internal box contains all of the digits from 1 to 9.
The Three Simple Rules
-
The Row Rule: Each horizontal row must contain numbers 1 through 9 without any repeats.
-
The Column Rule: Each vertical column must contain numbers 1 through 9 without any repeats.
-
The Box Rule: Each of the nine sub-grids (marked by thicker borders) must contain numbers 1 through 9 without any repeats.
Pro Tips for Beginners
-
Scan for the “Easy Wins”: Start with the rows or boxes that already have the most numbers filled in. If a row has 7 numbers, the last 2 are much easier to guess!
-
Use the Process of Elimination: If you know a “5” can’t go in the first two rows of a box because of other 5s on the board, it must go in the third row.
-
Don’t Guess: Sudoku is a game of certainty. If you guess and get one number wrong, it will create a “butterfly effect” that ruins the rest of the puzzle.
-
Look for “Naked Singles”: This happens when a specific cell can only possibly hold one number because all other 8 digits are already present in its row, column, or box.
Technical Instructions
-
Select a Cell: Click or tap any empty square in the grid.
-
Enter a Number: Use your keyboard or your phone’s number pad to enter a digit from 1–9.
-
Check Your Progress: Click the “Verify” or “Check Answers” button to see if you’ve made any mistakes. Wrong numbers will be highlighted in red.
-
Start Fresh: Use the “New Game” or “Reset” button to generate a brand-new puzzle at any time.
Why play Sudoku?
Regularly solving logic puzzles like Sudoku has been shown to improve concentration, boost memory, and even reduce anxiety by providing a “flow state” task for the brain. Enjoy the game!
