Sudoku Game Rules That you Should Know

Sudoku Game Rules That you Should Know published on

Solving sudoku is always a challenging task. With the numbers playing their own game with your mind, the game gets interesting as you solve it and pass the difficulty levels. However, before you start playing the game and become a pro, you need to be familiar to the basic, yet important Sudoku game rules. So, if you are unaware about the game rules, learn about them here.

Sudoku Game Rules – Rows

In a traditional Sudoku puzzle, there are 9 rows. Each row in the grid must include the numbers starting from 1 to 9 (1, 2, 3, 4, 5, 6, 7, 8, 9). In each row, there should not be a single Duplicate or Identical number. If a number gets repeated, then it indicates that you have made a mistake while solving the puzzle.
For eg: In a row, the “Givens” or the numbers that have been pre-determined are 1, 2, 3 and 5. So, when you fill the remaining numbers in the row, you need to make sure that the given numbers are not repeated again.

Sudoku Game Rules – Columns

Similar to the rows, in a traditional Sudoku puzzle, there are 9 columns. And each of these columns include the numbers (1, 2, 3, 4, 5, 6, 7, 8, 9). Again, there should never be any duplicate number or repetitive number in the column when you solve the grid. This only makes each column in the grid unique.
For eg: In a column, the numbers pre-determined or the givens are: 2, 6 and 7. These numbers cannot be altered and should not be repeated when you fill the column with the remaining numbers. Every number in the column should hence be unique and within the range of 1 to 9.

Sudoku Game Rules – Regions

In a traditional Sudoku puzzle, a regular 3X3 box is called as a Region. Thus, overall in a Sudoku puzzle there are 9 regions that you have to solve.
Similar to the requirements of the rows and the columns in a Sudoku puzzle, every single region in the puzzle must also include the numbers from 1 to 9 (1, 2, 3, 4, 5, 6, 7, 8, 9). The rules for regions remain the same as those for rows and columns. Duplicate of identical numbers in a region are not permitted. Thus, every region in the puzzle grid will have its own unique set of numbers from 1 to 9.

For eg: In a Region which has the givens or the pre-determined numbers as, 1, 2 and 8, the remaining numbers need to be filled carefully without causing a repetitive number. The Givens in the region cannot be changed in any condition.

Overall, the main rule while playing a Sudoku game is that: You should play the game and complete the puzzle, filling every row, column and region, such that they all contain their own unique set of numbers, starting from 1 to 9, without any number being repeated.
