About Connect 4
Connect 4, also known as Four in a Row or Captain's Mistress, is a classic two-player connection board game. First launched commercially in 1974, it has become one of the most popular strategy games worldwide.
The game is simple to learn but offers deep strategic depth. Players must balance offensive play (setting up their own winning connections) with defensive play (blocking their opponent's threats). Advanced players can plan several moves ahead to create unstoppable winning positions.
This online version features a challenging AI opponent that uses minimax algorithm with alpha-beta pruning to make intelligent moves. The AI evaluates board positions, recognizes patterns, and plans ahead to provide a worthy challenge. Can you outsmart the computer?
