- The algorithm is made up of five logical steps
- It requires players to mark up empty boxes in the Sudoku grid with all possible remaining number and, by comparing number sets, to labour through a "tree" of options that ultimately provides a solution.
- As of now, the computer takes takes over an hour to solve a Sudoku puzzle. (See humans always outsmart computers ;))

This algorithm is certainly an achievement in the mathematical world and reinforces the fact that almost everything that can be depicted as a flowchart is solvable by computers. After all computers have been known to be super efficient in deconstructing seemingly tough problems and hammering out their solutions using computing power!
What puzzles me though is how come human beings are able to solve a difficult Sudoku in just 10-15 minutes time while this latest algorithm takes an hour to crack a Sudoku puzzle? Is it our logic sense or intuition or just our imagination that does the magic-Well, I don't know! What I do know is the fact that struggling with my pencil (I don't mean chewing the back of the pencil over and over again ;)) and working out a Sudoku puzzle on a Sunday morning is an adventure in itself. And the "Ahaaa" feeling (emotional high) you get post solving a puzzle keeps the excitement and the desire to solve the next puzzle on :D
