Connect 4

You can play against a human opponent or against the AI by checking the "Computer" checkbox (the computer always plays the Yellow). You can then choose the difficulty level (which can be changed during the game). Attention, difficulty level 6 or 7 can take a good ten seconds calculation but you can limit the computing time of the AI.

If the "Yellow" checkbox is checked, the Yellow player goes first, otherwise it's the Red player.

You can choose the animation style from the menu.
