### What Is The Game of Sudoku?

Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9×9 grid with digits so that each column, each row, and each of the nine 3×3 subgrids that compose the grid (also known as “boxes,” “blocks,” or “regions”) contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid with a unique solution.

### History of Sudoku

Howard Garns, an American architect, introduced the game to the Western world in 1979. However, it wasn’t until 2004 that Sudoku began to gain popularity in the United States after being featured in several newspapers and magazines.

Since then, it has become one of the most popular puzzle games in the world and can be found in newspapers, magazines, and online.

### Equipment

To play Sudoku, you will need a Sudoku board and a pencil. The board is usually a 9×9 grid with nine 3×3 subgrids. Each row, column, and subgrid must contain all of the numbers 1-9 without repeating any.

You can play online or on your phone if you don’t have a physical board. There are many free apps and websites that offer Sudoku puzzles of varying difficulty levels.

### Popular Strategies

Scanning rows and columns: One strategy for solving the puzzles is to scan each row and column and look for areas where a particular digit can go. This can help to narrow down the possible locations for a given digit and ultimately lead to the solution.

Looking for groups of two or three: Another strategy is to look for groups of two or three digits that appear in the same row, column, or 3×3 subgrid. These groups can help to narrow down the possible locations for a given digit and ultimately lead to the solution.

Trial and error: A third strategy is simply trying different digits in different locations until the puzzle is solved. This can be time-consuming, but it may be the only way to solve some particularly difficult puzzles.

### Are There Sudoku Events/Competitions?

World Sudoku Championships: The World Sudoku Championships is an annual event that attracts some of the best players from all over the globe. The competition is open to anyone, regardless of nationality or age.

US Sudoku Championships: The US Sudoku Championships is another annual event, this time specifically for players from the United States. Again, the competition is open to anyone meeting the eligibility requirements.
