Play Connect Four Game

To play Connect Four game is not very complex and the game is considered solved. The player with the first move wins if both sides play optimally.

In Connect Four, however, there are too many branches to simply go through all the possibilities quickly enough each time. Here we look ahead 4 to 12 moves, depending on the difficulty level.

Simplified, a tactic for the person with the first move (yellow in this case) is to have only one missing piece in the odd rows. If at the end only one column is not completely filled, yellow will fill up the odd rows and red will fill up the even rows. Correspondingly, a missing stone on an even row can bring red the possibility of winning later.

There is an online version where the optimal moves can be calculated:
