Sudoku is very easy to learn but devilishly hard to master. Many groups and cultures claim to have invented sudoku and these include the french around the turn of the 20th Century, the Japanese in the 1980's and and American puzzle magazine in 1979.

Whatever, the truth, Sudoku remains universally popular because of its simplicity and also fun and frustrating in equal measures...

Sudoku is universal! Anyone can play - you don't have to be a genius to have a go - but however good you are - you will only get better...

The goal of Sudoku is simple: Fill in the grid so the numbers 1-9 appear only once in each row, column, and each 3x3 box. That's it!

Remember - up and down only - diagonals don't count...

The first thing you wil see is a partially filled grid, like this one.

Just work through, logically working out what numbers need to be in each column. You can start with trying to work out a row, a columnn or small box. We usually start with whichever has most prefilled...
