What is Sudoku?

Sudoku is a logic-based puzzle game where your goal is to fill a 9×9 grid with numbers. The grid is divided into nine 3×3 smaller squares, sometimes called “boxes” or “regions.” At the start of the game, some of the cells in the grid are already filled in with numbers. These are your clues! Your job is to use these clues and your amazing brainpower to figure out where all the other numbers go. The main rule is simple but brilliant: you must place the numbers 1 through 9 into each row, each column, and each 3×3 box without repeating any number. This means every single row must have all the numbers from 1 to 9, every column must have the same, and every 3×3 box must also contain every number from 1 to 9 exactly once.

The game became a massive worldwide hit because it strikes the perfect balance between being simple and challenging. You do not need to be a math genius to play; there is no calculating or arithmetic involved at all! It is purely a game of logic and spotting patterns. This makes it incredibly accessible to people of all ages, from kids learning problem-solving to adults who want a relaxing way to keep their minds sharp. The feeling of completing a Sudoku grid is incredibly rewarding. Each number you place correctly brings you one step closer to the solution, creating a fun and engaging experience that has made it one of the most popular puzzle games in history. For those who take their puzzle-solving seriously, there is even a competitive scene. You can learn more about major events like the Sudoku Championship over at the Fandom wiki.

How to Play Sudoku

The main goal in Sudoku is to fill the entire 9×9 grid with the correct numbers, following the one simple rule: every row, column, and 3×3 box must contain the digits 1 through 9 with no repeats. Think of it like being a number detective. You have to look at the clues you are given and deduce where the missing numbers must go. The core loop of the game involves scanning the grid and using a process of elimination. For example, if you are trying to figure out what number goes in an empty square, you first look at its row. See which numbers from 1 to 9 are already there. Then, look at its column and do the same. Finally, look at its 3×3 box. By checking these three areas, you can cross off all the numbers that cannot go in that square, hopefully leaving you with only one possible answer!

A great way to start is by looking for the “low-hanging fruit.” Scan the entire puzzle for a number that appears many times already. For instance, if you see a lot of 5s on the board, it might be easier to figure out where the last few 5s need to be placed. You work your way through the puzzle, cell by cell, or number by number, until every single square is filled. As you place more numbers, you create new clues for yourself, which helps you solve the rest of the puzzle. It is a chain reaction of logic! If you ever place a number and realize it breaks the rule (for example, you have two 7s in one row), you know you have made a mistake somewhere and need to backtrack. Patience and careful thinking are your best tools.

Controls

Mastering the controls is key to winning. Our browser version of Sudoku is designed to be simple and intuitive to play on any device:

  • Mouse (on PC/Laptop): Click on any empty cell in the grid to select it. Once a cell is selected, you can either click on the number pad on the side of the screen or use your keyboard to type the number you want to place.
  • Keyboard (on PC/Laptop): Use the arrow keys on your keyboard to move the selection box between different cells in the grid. Press the number keys (1-9) to enter a digit into the selected cell. Press the ‘Delete’ or ‘Backspace’ key to clear a number from a cell.
  • Touchscreen (on Mobile/Tablet): Tap an empty cell to select it. Then, tap the number you want to enter from the on-screen number pad that appears. It is that easy!

Tips and Tricks to Win

Want to beat the high score and solve puzzles like a pro? Keep these strategies in mind:

  • Scan First, Solve Later: Before you place any numbers, take a moment to look over the whole grid. Scan each 3×3 box and see which number (from 1 to 9) appears the most often. If the number 8 appears in seven of the nine boxes, for example, it will be much easier to figure out where the last two 8s must go. This is called “cross-hatching” and it is a fundamental technique.
  • Find the “Naked Singles”: This is the easiest and most common way to solve a cell. A “naked single” is an empty cell where only one number is possible. Check the cell’s row, column, and 3×3 box. If eight of the nine possible numbers are already present in those areas, then the missing number is the only one that can go into that cell. Fill it in and use that new clue to find more!
  • Use Pencil Marks (Candidates): If you are not sure which number goes in a cell, you can make small notes of all the possible numbers (or “candidates”). For example, if a cell could be a 2, 5, or 9, you can write those three numbers lightly in the corner of the cell. As you solve other parts of the puzzle, you can come back and erase candidates until only one is left. This is a powerful strategy for medium and hard puzzles.
  • Look for “Hidden Singles”: This is a slightly more advanced trick. Sometimes, a cell might have multiple candidates. But if you look within a specific row, column, or box, you might find that one of those candidates can *only* go in that one specific cell. For example, in a certain 3×3 box, the number 4 might be a candidate in three different cells. But if you check the rows and columns for those three cells, you might discover that two of them cannot be a 4. That means the remaining cell *must* be the 4 for that box.
  • Don’t Guess: Sudoku is a game of 100% logic. There is always a logical reason for a number’s placement. Guessing might work on very easy puzzles, but on harder ones, a single wrong guess can cause a chain reaction of mistakes that is almost impossible to find and fix. If you get stuck, it is better to re-examine the board or take a break than to guess randomly.
