Sudoko craze means your days are numbered
Bleeding Edge is already addicted to cryptic crosswords, so we don't know if we even dare look at the new sudoko puzzle that The Age gave us a taste of yesterday, and officially launches tomorrow.
Invented in Basel, Switzerland, by an 18th Century mathematician called Leonhard Euler, Sudoko made its way via Japan, and a New Zealand-born judge and amateur computer programmer, Wayne Gould, to Britain, where newspapers swarmed over the idea. Their readers have apparently refused all nourishment until they are given their daily dose.
The victims are confronted with a grid of 81 squares, nine across by nine down, some containing numbers. You have to fill in the blanks, observing the following condition: each 3 x 3 box, as well as each row and each column, must contain the numbers 1 to 9.
You can pick up clues at the Daily Telegraph's Sudoko site, and there's a Dashboard widget for Sudoko-obsessed Mac owners.

Easy, but takes a while.
2 Hints below, do not read if you want to work them out yourself
1. There should be one square that is absolutely identifiable at the start (Except in harder versions).
2.Look for squares in a box where a missing number can only appear in one place and one place only in the box.
Good luck all
