    Default Sudoku Solver

    Well here's my challenge:
    Make a sudoku solver.To be honest, I don't know were to begin. I just need a general idea of the most efficient way to have my program solve it. So should I make it search the first row.. then diagonal or whatever.
    I just need a few tips/ideas thanks
    And no, this is not homework.

    Sudoku's are simple enough puzzles that they can be solved via brute-force with computers.

    Brute force you say?
    Alright I'll look into that.

    And I'll look at the sudoku solver by logic.
    Any more ideas/hints?

    You could try a stochastic approach

    *note: You'll either have a very slow running algorithm (might take days or weeks to find the solution), or soon become the richest person in the world.

    LOL.
    Well I've found several websites demonstrating how the approach to brute force a solution should look like, so I'm testing it right now on a 3*3 mini sudoku.
