Last week I discovered a web site where I can play Sudoku, solve it to participate in a redemption for a 5€ Amazon Coupon. To solve this Sudoku puzzle I can use my service http://hintdesk.com/Web/Silverlight/SudSol/ . I just take the puzzle, submit it to my service and let it solved, then fill in the result back to the puzzle. However I see it’s very uncomfortable for doing this job by hand. I must read carefully each square and enter it correctly to my service. I would like to do it automatically, that means I need a program which read the puzzle, solve it, submit result and submit my name and email. In this small blog, I will demonstrate a code snippet to do that. The Sudoku puzzle looks like the image below
