Wow, nice job! You did what I wanted to do, but I gave up on it after I realized how complex calculating the winner would be.

I noticed one "glitch" so far, and that is it seems to have no limits set for the number of disks in a column. That is, after a column gets full, the player can still add more disks to that column and make it overflow.

Other than that, you did a great job on it.

Edit: Found one more minor glitch. The winner calculator doesn't immediately register 4 in a horizontal row. So, one more disk must be dropped after the winning disk has been dropped.

Regarding "the player can still add more disks to that column and make it overflow.", I appreciate the feedback, but I'm not going to error trap for that case.

Regarding "one more disk must be dropped after the winning disk has been dropped", I think I fixed that (I hadn't allowed enough time for the lasers to detect the last disk dropped), let me know if you still see a problem.

The "one more disk" bug has been squashed.

I'm still waiting for that Connect Four 3D version.
