Overview

The main idea behind this, when user chooses to start a new game, the minefield, a bi-dimensional array is populated in memory, then rendered on screen as buttons, whenever any button is clicked, we check if the corresponding array element contains a mine or not, if not, we try to count how many mines are there around, if there's at least one, we tell that as the button label, if there's no mines at all, we reveal this and the 8 places around it recursively.
