What is Sudoku?

Sudoku is a numbers puzzle game and comparable to a crossword puzzle.

The puzzle itself is a grid of little boxes, also called cells. Nine cells are stacked within a larger container. The larger boxes are stacked again in a 3x3 grid. So in total, there are 9 larger boxes and a total of 81 cells.

Depending on the difficulty, the puzzle comes with more or less prefilled cells. The more challenging the puzzle, the fewer cells are prefilled with numbers.

Sudoku is one of the most popular puzzle games to train your brain and develop your intelligence.

The first-ever Sudoku was created by a Swiss mathematician called Leonhard Euler. And two centuries later, it got picked up by Dell Puzzle Magazines, which has been producing crosswords and other puzzles since 1931.

Further development to a web version of Sudoku was held in Japan. They also invented the name Sudoku. And in 2004, Sudoku was first published in the “Times” as an online game.

How to Play Sudoku

To master Sudoku, players aim to fill a 9x9 grid with numbers ranging from 1 to 9. The grid is divided into nine 3x3 boxes, ensuring that every row, column, and individual box contains unique digits. Remember:

Every row should feature each number from 1-9 exactly once.
Each column must have distinct numbers without repetition.
Every 3x3 box should be populated with unique numbers, with no repetitions.

Some cells will have pre-filled numbers, guiding the player. The essence of the challenge is to logically determine and fill in the missing numbers.

Mastering Sudoku: Helpful Sudoku Tips

Embarking on Sudoku might seem daunting, but with practice and a few strategies, it becomes an addictive joy:

Tip 1: Eye rows, columns, or 3x3 boxes populated with 5 or more digits. Analyze the absent numbers, as often, they’ll fit into just one spot considering its neighboring digits.
Tip 2: Segment the board into 3 primary columns and rows. Each column or row consists of three 3x3 boxes. If two identical numbers appear in a column or box, logic dictates the third instance of that number must fit into the remaining 9-cell section. Evaluate these cells to pinpoint the elusive digit.
