How the following look?
From http://news.bbc.co.uk/1/hi/magazine/4469719.stm
For those who don't know, it's a puzzle found in newspapers, books and
online. A simple-looking grid of nine rows by nine, split into nine
boxes, each containing nine squares, it looks like just another
numbers game.
But, say Su Doku experts, the difference is it can be played using
logic alone, so maths phobics read on.
To be pure Su Doku each of the unique puzzles - which come in varying
levels of difficulty - must have only one solution. The aim? To fill
in the grid so that every row, every column, and every box contains
the digits one to nine
