Patrick McCabe may be the only Connect Four player in the world, thanks to a robot, his project at MIT Microcomputer Lab. The robot is slow and noisy, but it uses its keen brain to make up for the shortcomings of this machine that uses crude oil.


Some people are not aware that even the fourth is a game that has already been solved. Given any given state to match, all predictions can be given and there is a mature open strategy, which will inevitably lead to a victory. Patrick uses the Negamax algorithm and proposes a heuristic way to let his robot analyze the current state and determine the best steps in the remaining possible actions.
To make it easier for everyone to use, Patrick added difficulty settings and hints. Of course, tips are more stupid than setting difficulty. Even four can be seen as a combination of Tetris and Gobang.
