All my friends are fantastic at sudoku and they LOVE it, but i don’t, mainly because well, I can’t solve those things. I just want to know for those sudoku solvers out there how do you solve them, is it natural ability, patience, or secret formula that I don’t know about…? Thanks.

I just learned how to do sudoku and can do the easy ones really fast now, I am beginning to work on the medium ones and sometimes get stuck but not always.

Does anyone have any tips?
Also, what are the best books for beginners to intermediate(or someone like me) to work on and get better and eventually work up to the hard and challening puzzles?

Most of the ‘hard’ Sudoku puzzles I do have 22-24 clues to start off with. Are there some with fewer clues? I’m looking for a real challenge. What is the minimum amount of clues that still lead to a solvable puzzle?
