I have just finished the application introduced in previous post. To remind what the application is about: it is an implementation of a classic game Minesweeper. My addition to the idea is that once you click on a mine you have one chance to disarm the mine by solving small equation (addition or subtraction).
Here are links to ClickOnce installer and source code. As usual the code was written in MS Visual Studio.
One note before you try it out – don’t mind the graphics. I am hopeless at drawings.
