<p>I have no idea why I can't think straight right now but as of right now, but I was hoping for some help in developing an algorithm for my sudoku puzzle. I have a a list of possible numbers that can go in each cell after checking all the rows, columns, and 3x3's. I have code for placing numbers into each cell. However, I'm having a lot of trouble with the backtrakcing aspect. Can anyone help me with some psuedocode for the backtracking part of the sudoku puzzle?</p>

<p>Thanks. </p>
