About Four in a Row

Four in a Row is a brilliant strategic falling-piece game invented by Howard Wexler and Ned Scheidt in 1974. Two players take turns dropping colored discs into a vertical 7×6 grid, with gravity pulling each disc to the lowest available position in the chosen column. The first player to connect four of their discs in a row — horizontally, vertically, or diagonally — wins. First to four in a row takes the game. While Four in a Row appears simpler than Chess or Checkers, it has surprising strategic depth. In 1988, mathematicians proved that the first player can always force a win with perfect play — but that solution requires following a complex sequence of moves that is impossible to memorize in practice. Against a real opponent, the game feels genuinely balanced and competitive. The strategic vocabulary of Four in a Row is rich. "Threats" are positions where a player has three in a row with one open space — a single move from winning. "Double threats" (two simultaneous threats) are unblockable and form the basis of most winning strategies. Setting up a double threat while preventing your opponent from doing the same is the game's central tactical challenge. Column control matters: the center column offers the most connectivity (connections can extend left, right, and diagonally), making it the most valuable real estate. Players who control the center and one adjacent column early in the game consistently have more strategic options. However, being too predictable in column preference allows your opponent to build threats on your neglected side. Our version features two modes: two-player (local) and single-player against an AI opponent that plays at a solid intermediate level — it will set up threats and block obvious winning moves, but can be beaten with planning. The clean grid interface highlights your winning connection when you achieve it with a satisfying animation. **Strategy tip:** The first player's power move is center column. Follow up by building diagonal threats in both directions. Force your opponent to block in one direction, then complete the other.
