How to improve at Connect Four
Connect Four is a gravity-based strategy game against the computer. Every disc falls to the lowest open space, so plans must account for which squares can actually be reached. Build multiple threats, defend the center columns, and avoid placing the support disc that gives the computer a winning move.
