What is Sudoku? Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a 9x9 grid with digits so that each column, each row, and each of the nine 3x3 subgrids that compose the grid (also called "boxes", "blocks", or "regions") contain all of the digits from 1 to 9. The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.
Origins of Sudoku: The concept of Sudoku originated in Japan in 1979, when it was introduced by Nikoli Co., Ltd. under the name "Sudoku." The name "Sudoku" is derived from the Japanese words "suu" (single) and "doku" (number), which together mean "single number." However, the roots of Sudoku can be traced back to earlier puzzles, such as Latin squares and crosswords.
Rules of Sudoku:
- The grid is divided into nine 3x3 subgrids, also known as "boxes" or "regions."
- Each row, column, and 3x3 subgrid must contain the digits 1-9 without repetition.
