What algorithm will create a sudoku puzzle?


Question asked by: mrquestion

Asked on: 07 Jan 2010

To create a sudoku puzzle then you need a simple algorithm.

First of all you need to fill the grid.

To do this you basically pick the first cell and randomly place a number from 1 - 9, you keep on going for each cell placing a number from 1 - 9 and substituting it for another number if it conflicts with a number already in that row, column or box.

You keep doing this until either you fill the puzzle or run out of options for a cell in which case you backtrack to the previous cell that has options and try another option and so on. When you hit a solution you stop the process.

This is your filled grid and from there you can go through the process of creating an actual puzzle.
