To learn how to build an automatic Sudoku puzzle solver with OpenCV, Deep Learning, and OCR, just keep reading. Seems like a win/win.Īnd from my perspective, perhaps if I publish a tutorial on Sudoku, maybe I can get back in my wife’s good graces. The Sudoku puzzle company makes more money, and the end users are happy. If the Sudoku puzzle manufacturers didn’t have to print the answer key in the back of the book and instead provided an app for users to check their puzzles, the printers could either pocket the savings or print additional puzzles at no cost. I have a Ph.D in computer science, but all of that went over my head.īut for those of you who aren’t married to a Sudoku grand master like I am, it does raise the question:Ĭan OpenCV and OCR be used to solve and check Sudoku puzzles? She then lectured me for 20 minutes on how she only solves “level 4 and 5 puzzles,” followed by a lesson on the “X-wing” and “Y-wing” techniques to Sudoku puzzle solving. My wife doesn’t get mad easily, but let me tell you, I touched a nerve when I innocently and unknowingly insulted her Sudoku puzzle solving skills. And most importantly, she doesn’t solve a puzzle incorrectly.All you need to do is flip to the back of the book, locate the puzzle number, and see the solution. Yes, there is a solution key in the back.How do you know if you solved the puzzle correctly? Is there a solution sheet in the back of the book? Or do you just do it and hope it’s correct?Īpparently, that was a stupid question to ask, for two reasons: I’m not a big puzzle person myself, but one time, we were sitting on a flight, and I asked: She hates the digital/smartphone app versions and refuses to play them. The funny thing is, she prefers the printed Sudoku puzzle books. Every time we travel, whether it be a 45-minute flight from Philadelphia to Albany or a 6-hour transcontinental flight to California, she always has a Sudoku puzzle with her.
