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.
