Just about the whole team here are into their puzzles and games. Some started out very young and in a series of posts about games & puzzles it seemed very appropriate to start with the standout favourite, Sudoku. A great numbers game, Sudoku for kids is fun and challenging all at once.
What is Sudoku?
Sudoku is a logic based number placement puzzle. Comprised of a 9 x 9 grid, the game is completed when each row and column contains the numbers 1-9. To add a further layer, each 3 x 3 square within the game must also comprise each number 1-9.
Wikipedia has the first variant of the modern Sudoku appearing in a French newspaper in 1892. It credits the modern version of the game to an American, Howard Garns who saw the first puzzle published in 1979. Typically we think of Sudoku as Japanese in origin and we believe the game was introduced there in the 1980s. The credit for the spread of the game outside of Japan goes to a Hong Kong judge, Wayne Gold, who saw the game in a Japanese bookshop and was obviously immediately hooked. So hooked in fact that he spent the the next 6 years writing a program to generate new puzzles! He pitched the puzzles to The Times in London and the first puzzle was printed on 12 November 2004. The rest, as they say, is history.
What is the key to success?
In broad terms, completing a Sudoku puzzle requires the application of logic, reasoning and deduction, an analytical mind and perhaps most of all, patience. We aren’t wanting to go too far with the science and I think we can all agree that these are the skills needed for problem solving of any nature. Take the principles and apply them to this number based game. In practical terms, however, there are many different approaches. Some will start with the columns and then work row by row while some start trying to place all the 1s then the 2s, etc. With Sudoku, it’s definitely not a one size fits all strategy that works.
Sudoku World Records – Fastest
It’s been difficult to nail this down precisely but we have found in several different sources that the record is 1min 23.93secs. We are left to assume this was a fairly tough version but even if it wasn’t that is still a pretty speedy record.
