What is Sudoku and how to play it

Sudoku is a logic-based, combinatorial number-placement puzzle that originated in Japan in the 1980s. The name Sudoku comes from the Japanese phrase "sūji wa dokushin ni kagiru", which means "the digits are limited to one occurrence".

The objective of Sudoku is to fill a 9x9 grid with digits from 1 to 9, so that each row, column, and 3x3 subgrid (also called "box", "block", or "region") contains all of the digits exactly once. The puzzle setter provides a partially completed grid, which has a single solution.

The basic rules of Sudoku

Here are the three main rules of Sudoku that you need to follow:

  • You can only use the numbers 1 to 9 in each cell.

  • You cannot repeat any number in the same row, column, or subgrid.

  • You cannot guess or use trial and error. You have to use logic and reasoning to find the solution.

These rules may seem simple, but they can make the puzzle very challenging, especially as the difficulty level increases. However, they also make the puzzle very satisfying, as you can always find the solution by applying logic and eliminating possibilities.
