Tic Tak The L电脑版

This is a game which I have made from the common game called Tic Tac Toe. In this game, the board is not the typical 3 by 3 but instead 4 by 4 so it has a total of 16 boxes. The purpose is to either make 4 in a row, column, or diagonal. Furthermore, one can also make an L with any 4 boxes in any direction. The first player to acheive any one of these will be the winner!
