Anyone good at Sudoku here?

Does anyone play Sudoku? I've tried solving these puzzles in the daily newspapers many times, but hardly ever get it right. Probably because I'm not a numbers person and math has never been my strong point. I am amazed to see my sister and one of my guy friends solve these puzzles so quickly and effortlessly. Kinda does a number on my self-esteem. :P

Yes I think its is great, but there is a misconception that it is a math problem. It's not a math problem, it is a logic problem To prove it just change all the numbers (1-9) to letters (A-I) and you solve the puzzles the same way.

I Love sudoku. I think you should try the online versions where they have multiple difficulty levels. Will help you with developing a mental algorithm

There are many mathematical problems and many areas of mathematics that have nothing to do with numbers. In many mathematical papers the only numbers are the page numbers. Some people would consider logic a part of mathematics and logicians are often in departments of mathematics. The reasoning in Sudoku is similar to the reasoning mathematicians use in proving theorems. If you asked a mathematician to describe mathematics, thye might never mention the word number and describe it as a language and a way of thinking. (Or they might be cute and say that mathematics is what mathematicians do.) You are correct, however, in that you can have fun solving Sudoku puzzles without knowing any formal mathematics.

Oh, so that's my problem. I forgot to mention that I'm not very good at "logic", either. Of all the math classes, trigonometry (sine, cosine, hypotenuse, etc.) was the most difficult for me. I would never make it as a mathematician or engineer. Will try changing the numbers to letters and see if that helps any.

Iswswein: Thanks for the sudoku website. I'll check it out and will tell my sister and friends (who love these puzzles) about the site. Maybe if I practice more, I'll get better? ..

John Tuttle: Your explanation about logic/math makes sense. I remember when I used to visit my brother-in-law at his office at the University of Washington where he was finishing up his Ph.D. in Theoretical (Astro) Physics. A lot of his research work involved proving theories, and I recall pages of papers he produced with line after line of equations and symbols and lines and squiggles. It did look like a foreign "language". It was definitely all Greek to me.

My husband and I love these puzzles. He's sort of an addict. We like to race each other.

I'm quicker at most of them, but he will stick to a really hard one longer than I will.

Re: Anyone good at Sudoku here?

I love Sudoku! Has anyone ever done the Sudoku that has 5 blocks to it. Each X represents the 9 big square (81 small squares):
X X
X
X X

where the middle block intersects with the other 4? When I first saw one like this I thought it would be really tough. I did one the other day & it was actually even easier than regular puzzle.

I have never seen one of these.
