International Sudoku Day

International Sudoku Day

Sudoku lovers rejoice!

Many people believe Sudoku has ancient roots in Asia. However, it is actually an invention that is relatively recent. Leonhard Euler, a Swiss mathematician, invented a similar game called Latin Squares in the late 1800s. The only difference is that at the time, the game wasn’t divided into blocks of nine.

Howard Garns, a Connersville, Indiana-based puzzle creator, submitted his puzzle almost two hundred years later to an American puzzle magazine, Dell Pencil Puzzles & Word Games. “Number Place”, the puzzle was published for the first time in 1979 in a book of random puzzles.

The puzzle was not popular at the time and it continued to appear in Dell’s puzzle collection books.

Number Place was already in Japan by 1984. Crossword puzzles in Japanese are difficult, but Number Place requires only numbers to make it easier. Sudoku was pronounced “Soodoe-koo”, which means “the numbers must stay single”.

Sudoku was a fascination for two decades in Far East, until a tourist visiting Tokyo in the 1990s discovered that Sudoku is now a popular pastime. Wayne Gould, a New Zealand judge, saw the squares. He became an avid fan of filling them in.

Over the next few years, Gould went one step further and created a computer program to automatically create Sudoku puzzles. Although the first Sudoku puzzle was published in a US newspaper in 2003, it did not get much attention.

Gould’s wife presented Gould’s work to The London Times. They printed a Sudoku puzzle for their newspaper in 2004. It quickly grew in popularity and became ‘viral. Sudoku puzzles began appearing in puzzle books, while Sudoku books were becoming more popular.

Although no one knows why Sudoku is so popular, some believe it has something to do with humans’ natural desire to make order out of chaos. It gives people a sense accomplishment and productivity when they are able to solve Sudoku puzzles. This makes one feel like a winner. They are!

The World Puzzle Federation created International Sudoku Day in 2013 to recognize this addictive, unique and challenging game. Enjoy these puzzles as a celebration of International Sudoku Day.

International Sudoku Day offers a chance to have fun and train your brain! These are some ways you can celebrate and enjoy the day.

Get out a pencil, and you’ll have tons of fun! Although it might seem daunting at first, the numbers have nothing to do with mathematics. The numbers are placeholders. You can use the game with any letters or symbols. It is easy to make sure every row or column in a column is correctly filled out by using the numbers.

Sudoku is played using a grid consisting of 81 squares that are broken down into nine blocks. The rules are very simple. Each column, row, or block of nine must contain at least one number of each number, with no duplicates. It is possible to complete the puzzle by using the numbers already in the grid and the elimination process.

Many Sudoku puzzle books include tips and instructions in the first few pages. This makes it easy for beginners to get started. Many Sudoku books offer easy, medium and hard puzzles to help beginners get to grips with the game. For puzzlers who really need help, some puzzles offer hints and answers.
