What Is Sudoku?
Whether you are traveling or just relaxing on a Sunday morning,
Sudoku is a pastime that the whole family can enjoy. The Sudoku
craze has taken over. It is goodbye to crossword puzzles and
magic squares and hello to Sudoku. If you search the word
Sudoku on Google™, you will get over 70 million hits. Sudoku
puzzles are published in newspapers, magazines, and books.
They even come in electronic handheld games or interactive
games on the Web.
Sudoku is a logic puzzle. Each puzzle has one or more mini-grids.
Each mini-grid has boxes that are arranged in rows and columns.
Hints are given in some of the boxes. There are different types of puzzles. The puzzles can be
1 x 1 grids, 2 x 2 grids, 2 x 3 grids, 3 x 3 grids, or even more. Pictures, letters, and numbers are
all used within the puzzles in this series.
The objective of a Sudoku puzzle is to fill in all the boxes of the puzzle using only the given
hints. Each column, row, and mini-grid must have each picture, letter, or number only once.
That means you have to pay attention to three things while you try to solve these puzzles.
You have to look up and down the column, across the row, and around the mini-grid!
The History of Sudoku
How did the Sudoku craze start? Sudoku puzzles first appeared in a U.S. magazine in 1979.
At that time it was called “number place.” A magazine editor from Japan saw the number place
puzzle and liked it so much that he decided to create a magazine with his version of it. He
called the puzzle Sudoku. The word su in Japanese means number, and the word doku means
single. The puzzle became very popular in Japan. Today, 660,000 Sudoku magazines are
circulated every month in Japan.
