Sudoku has taken the world by storm.
Hundreds of thousands
of people worldwide are addicted, with the top
ten books in the non-fiction best seller
lists dominated by Sudoku, or Su Doku as it is also known.
As an indication of the worldwide appeal, this site had visitors
from 127 different countries in a single month!
What do you do?
The aim is to fill in the grid so that each
row, each column and each 3x3 box contain the numbers
1,2,...,9. Simple as that! However, it's not always
easy of course, and sometimes fiendishly difficult.
But it's fun to learn strategies for yourself
by just having a go. The puzzle on the right is an easy one - click on the image to see the solution.
Sudoku grids can be automatically compiled
by a computer. However, one must be careful to check
that there is only one solution, and hand crafted puzzles
by experts have been claimed by some (e.g. the Guardian)
to be superior.
Look around the site for lots of recommended printable puzzles,
on-line games, a shop, our Sudoku solver, Su Doku variants
and much more.
