How to solve each sudoku?
Sudoku is not difficult to learn to solve. It does not require computational operations, but it is logically very challenging. Because of this, it became a favorite brain teaser for many. Crook's algorithm is the first mathematical formula proven to solve all Sudoku problems. Crook's system requires players to enter all possible remaining numbers in the empty cells and then, by comparing sets of numbers, arrive at the final solution. Solving Sudoku this way takes about an hour.
