Sudoku

Have you heard of this? My father's been telling me about it for a couple of months since he has become hooked on these puzzles. Yesterday I took the plunge and decided to take a look at what Sudoku is all about. At first I thought this was a math puzzle so I really wasn't that interested. But now that I have explored it I have learned that it's basically a logic based placement puzzle. You can read more about it at Wikipedia. What I like about this game is that I can play it on a piece of paper anywhere. It seems that so many of the games I enjoy are computer games, which really defeats the purpose of having some recreation time because I'm on my computer all day anyways. Now I have found something I can do off the computer. Sudoku-puzzles.net allows you to choose your level of difficulty, play online , or be able to print up to four puzzles on a page. Yesterday, I did my first one and it took me about 20 minutes so I did a second one and that took me only 10 minutes. Of course that was that at the easy level. Last night I decided to try the medium level and I am still working on that one. I was almost finished and then I realized that I goofed up somewhere and had to start backtracking to find my mistake. Now I am hooked. Thanks Dad!
