Books4TheBeach today would like to share some interesting info on the latest phenomena Sudoku, a Japanese numbers puzzle.
Sudoku requires a player to fill in the 9 x 9 square grid with the numbers 1-9. You have to arrange the numbers in such a way that each column, row and mini grid only contains 1 of each number. By placing just one number incorrectly the whole puzzle is thrown out.
Sudoku or very similar was invented 200 years ago by a blind Swiss mathematician (Leon Hard Euler) from Basle. Leon lost his sight in his early middle age and after finding he could no longer work from books, developed a talent for composing puzzles and an ability to compile complex sums in his head.
Leon went on to develop a grid based puzzle and called it 'Latin Squares' and was made in all material aspects. Leon's 'Latin Squares' was little noticed until it appeared as the 'Number Place Game' in America in the 1980's. It was eventually noticed by Nobuhiko Kanamoto a Japanese employee of a puzzle magazine. The Japanese then further developed this puzzle and renamed it Sudoku meaning 'number single'.
Today Sudoku is not only spreading widely through newspapers and across the internet, but is now heading for television in the UK.
For all you you Sudoku fans we have found a couple of interesting sites:
