Next Connect Four Move calculates mathematically optimal moves in milliseconds directly in your browser. Powered by a 49-bit BigInt bitboard engine with Negamax Alpha-Beta pruning and a 120,000-entry Transposition Table, the solver evaluates future game positions to find the single best column, identify forced win sequences, and warn against game-losing blunder traps (TRAP in red).
The center column (Column 4) participates in 66 distinct winning four-in-a-row lines—far more than any other column on the 7×6 grid. Controlling the center column early gives you dominant offensive and defensive flexibility across horizontal, vertical, and diagonal lines, preventing your opponent from connecting four across the middle of the board.
1. What is the best first move in Connect Four?
Dropping your first disc in Column 4 (the exact center column) is mathematically the only winning opening move. In 1988, computer scientist Victor Allis proved that with perfect play, Player 1 (Red) always forces a win starting in Column 4.
