I've had this idea for EVER, and finally decided to pull the pin and go through with it... honestly a simple thought, the game of minesweeper one of the few inbuilt games on my PC as a child that I never had the patience to finish, but this one will be completable because it has only one square (which is a mine). Technically you can lose too, which I did many times building the "right click" to flag mine functionality.
You can play it on its new url, onesquareminesweeper.com as well as view the source on github.
