Number Place Breaker

Number Place Breaker is an app that automatically solves a Number Place (also known as Sudoku) puzzle. It is a sort of apps usually called Sudoku Solver. However, unlike most of other sudoku solvers, you don't need to type in a puzzle. Use your phone's camera to take a picture of a puzzle, and touch the [Solve] button. That's all. The solution to the puzzle then appears on the screen. It takes several seconds, but that's surely faster than you, isn't it?

Note that this app has no practical usages. Please consider it as an experiment, a proof of concept, or a technology demonstration.

NOTE ON OpenCV Manager

The Number Place Breaker internally uses another app, OpenCV Manager, available for free download on Google Play, for image processing. When you first run the Number Place Breaker, it asks you to install it (unless you already have one) and guide you to the download page. Please follow the instruction and install the OpenCV Manager when it happens. The Number Place Breaker can't capture a puzzle unless OpenCV Manager is installed. OpenCV Manager is available at: https://play.google.com/store/apps/details?id=org.opencv.engine
