### Sudoku, a cross number puzzle

This is a part of Sudoku, cross "number" puzzle. This puzzle is becoming popular now in Japan.

The below photo is a whole Sudoku grid, consisted of 9x9 cells. Each cell must be filled with one digit number by the following rule: fill in the grid so that every row, every column, and every 3x3 box contains the digits 1 to 9.

The digits to be entered are 1, 2, 3, 4, 5, 6, 7, 8 and 9.

Each row has 9 cells wide. A fill-in row must have one of each digit. That means that each digit appears only once in the row. There are 9 rows in the grid and the same applies to each of them.

Each column is the same as the rows.

The box, containing 9 cells in a 3x3 layout. A filled-in box must have one of each digit. That means that each digit appears only once in the box. There are 9 boxs in the grid and the same applies to each of them.

If you are interested in this puzzle, why not print out this and try this for a relax??

I love doing Sudokus. It sometimes drives my wife potty, as I'm not doing other things.

This has been a rage in the UK for about two years now.
I had a little version on my computer -- not got it now - must have been on my old one and I've not put it back here - may look for it.
I bought an electronic one to take on holiday but the batteries soon die.

If you want to try out something new in sudoku, try shendoku, using the sudoku rules but playing two people, one against the other, like battleshipps. They have a free version to download at http://www.shendoku.com/sample.pdf . Anything else they are bringing out or they are working on you can find at www.shendoku.com or at they´r blog www.shendoku.blogspot.com . Have fun, I am. I specially like one slogan I heard about Shendoku: SUDOKU is like masturbation (one person)…. SHENDOKU is like sex (it takes two).
