The puzzling popularity of Su Doku !
Su-doku puzzles (also spelt Sudoku) are 9x9 grids of numbers, subdivided into 3x3 blocks. When you begin a puzzle, some of the numbers are already filled in, and you have to fill in the blank squares using logic. You must fill the grid so that all the numbers 1-9 appear in each row, column and 3x3 box. However, no row, column or 3x3 box may have two of the same number.
Su-doku puzzles first appeared in New York in the late 1970's under the title "Number Place". They were introduced to Japan in 1984 where they were renamed to Su-doku (pronounced sue-do-koo; su = number, doku = single), so su-doku translates as "single number".
There are also many fascinating varients of Su-doku, of one which is "Killer" Su-doku, which combines elements of Kakuro. "Desktop Su-doku" is the only PC game which features Killer Su-doku puzzles, and Su-doku X
