Aline in 4

This is a game that you play against computer. You are given pieces marked as 'x' and dropped your pieces to the game board with grid size of 8 columns x 12 rows. Your task is to make 4 pieces of 'x' in a straight line horizontally, vertically or diagonally.

You can choose between two computer agents X or Y to play with. Both agents play the game with different strategy, one rule-based and the other score-based.

See if you can defeat them both.
