This is a simple macOS game where you have to connect X coins of the same color in a row (diagonally, vertically or horizontally).
I'm doing that based on where the coin was added. So, if added on IndexPath 0,0, I start checking around this index, so it's not necessary to check the whole board. There still some improvements to be done, by the way.
I still have to add configurations in order to change how many items to connect in a row, if the user wants to play agains other players or the not intelligent AI and how many collumns and rows are available.
