Recently, I have been having some fun learning to play a game called Sudoku(pronounced Soo-Dough-Koo). It looks challenging, and sounds challenging, and it is challenging. :) The object of the game is to fill the board with numbers. Now you cannot fill the board with random numbers, you have to fill it all out with the numbers 1-9. Sounds easy, huh? WRONG!
You must fit the numbers 1-9 in every column without repeating any numbers in that column. That makes it a little more difficult. But you havent heard the end of it yet! You must also put the num,bers 1-9 in every row without repeating. That sounds pretty hard, doesn't it?
Well, if you study a Sudoku puzzle board, then you will notice that there are rows of nine, columns of nine, and then there are boxes of nine. Yes, that's right, boxes. If you are thinking what I think your thinking, then I don't have to tell you that you also have to fit 1-9 in every box without repeating as well!
It might make more sense if you study a solved one.

So as you can see it can get pretty complicated. The game is mainly a process of ellimination. First you would look at the row and see, "Is there a 1?" and if there isn't you would find all the possible places in the row to put the 1, and mark it as optional. As you sontinue and find more areas where other 1's can be, you will eliminate more and more, and therefore leave only one left. Here are a few more puzzles that we have completed.

Now that you have seen it, why go to the stores for a book? Play it online free here! If you need some better instructions for playing, and some hints as well for how to solve, simply go to http://www.sudoku.net/ and explore around!
Have fun!

If you search "sudoku" in Wikipedia, you will also be given some strategies for winning.
That game is too complicated for me... but I'm glad you have fun with it!
I have tried some of these before, and I agree that they are hard! One thing that I didn't know was that each box should have the numbers 1-9 without repeating. Now that I know that, maybe I will be more successful in solving these!
Yes, I think it is actually easier to do with the boxes.
Now that you know of that, you should see KILLER Sudoku! Now that is challenging!
Look Here!
Yikes! That (Killer Sudoku) would definately be difficult.
Sudoku who came up with the spelling! Well that would keep you occupied for awhile.
I remember you and mom doing those things all night!
