Sudoku Puzzles : Play Online Easy and Hard with Timer

About Sudoku PuzzleHow to Play SudokuPlay Sudoku

Sudoku, originally called Number Place is a logic-based, combinational number puzzle. French newspapers featured variations of the puzzles in the 19th century, and the puzzle has appeared since 1979 in puzzle books under the name Number Place. However, the modern Sudoku only started to become mainstream in 1986 by the Japanese puzzle company Nikoli under the name Sudoku, meaning “single number”. It first appeared in a US newspaper and then The Times (UK) in 2004, from the efforts of Wayne Gould, who devised a computer program to rapidly produce distinct puzzles.

How to Play: Each Sudoku Puzzle has a grid of 9 squares wide and 9 squares deep. The lines of squares running horizontally are called rows, and the lines running vertically are called columns. The grid is further divided into nine 3 X 3 square ‘boxes’.

You will find some of the squares already having numbers in them. Your task is to fill in the blank squares. The rule is:

  • Each row, column and 3 X 3 square box must have numbers filled up from 1 to 9.
  • Each number can only appear once in a row, column or a 3 X 3 box.
