Sudoku is the most popular logic puzzle in Japan also
known as Suduko, Sudoko, Su do ku, Sodoku, Suduku. It
is very simple to learn, requires no calculations, and
provides a surprisingly wide variety of logic
situations. From children to old can enjoy it for a
pass-time. The game refers to a number placement
puzzle also known as Number Place in USA. First
Japanese title of this puzzle is "Suuji wa dokushin ni
kagiru". It's means that number is limited only single
(unmarried). But this title is too long, then it was
abbreviated as "Sudoku". So "SU" means number, "DOKU"
means single. The puzzle seems to have first been
published in the USA before being noticed and then
popularised in Japan.
The rules of the puzzle are simple. Each row, column
and minibox comprises the numbers 1 through 9. The
solver must complete the missing numbers. The
attraction of the puzzle is that the completion rules
are so simple and yet the overall task can be
difficult.
Sudoku is recommended by some teachers as an exercise
in logical reasoning. This game also can be used as
Sudoku solver. It is easy to solve your sudoku puzzles
and try to find right solutions for any game
combinations.
