Sudoku

I put in an order for some scripts at wal-mart and had to wait 30 minutes. During that time, I aimlessly wandered through the store with nothing to do. During my walkabout, I came across a small puzzle game called Sudoku (??). It looked like a magic square that you had to fill in.

I like logic games and it was only five bucks. Suddenly my super powers of frugality’s kicked in. I took a picture of the box with my camera phone and decided to look it up on the internet when I got home. I was in luck. There are many sites covering Sudoku. I found one called Web Sudoku. It took a while for me to figure out, but here are the basic rules:

  • You can only use numbers 1 through 9
  • You can only use each number once within each 3×3 grid within the 9×9 grid.
  • You can only use each number once in each vertical column of the entire 9×9 grid.
  • You can only use each number once in each horizontal row of the entire 9×9 grid.

So I went ahead and tried my luck. I got off to a slow start the first time just trying to figure out what I had to do. I finished in 30 minutes. I thought I did OK until I saw that the average time for an easy puzzle was about seven minutes. I figured I could do better since I got through the first OK. Wrong! It took me even longer. Somewhere I mixed up some numbers in my strategy and had to backtrack.

This game is a little addicting. It’s as if the game is a cross between minesweeper, magic squares, and crossword puzzles. Along the way, you could click a button that would tell you if something doesn’t add up and highlights the row, column, or section in red. It’s a little addicting, so make sure you don’t have anything to do before you start.
