Well, that sounds to me like it tries every possible combination of numbers until it comes up with the right one (brute force without trying to apply tactics) - an overglorified, but fast, form of trial and error. With that approach you'd eventually end up with a solution to ANY sudoku, but not in a logical sequence, and you'd have no idea how you got there or what to do if you got stuck solving manually.
