Was going to put this in Games, but Sudoku is more a logic puzzle. There are a lot of strategies for solving Sudodu, and I can do all the ones in the newspapers and mags. But the ones on the Net are much harder. Are there ones so hard that no solution can be found except to use brute number-crunching force (by computer) to get a solution?

in a contest, what is the easier and faster technique to bit your opponents in solving sudoku puzzle. please help me.

please any one give me the names of different algoritms for generating and solving a SUDOKU puzzle….please.its very urgent…..my inbox is waiting for ur answers….pleaseeeeeee.

There are plently of sites and a few books that teach how to solve Sudoku. I’m NOT refering to these. I want to learn to solve Sudoku faster. I want to improve my speed significantly. I want to solve them twice or thrice faster than I do now, regardless of my current speed. Are there any techniques?

I like spider sudoku, but I can’t download anything, and i don’t want to pay.

Has anybody found a free, safe and pretty decent downloadable game of sudoku for their blackberry pearl? If not, which one is worth paying for? THANKS!
