How to Play
Click a column to drop a piece. First to connect four in a row (horizontal, vertical, or diagonal) wins.
Objective
Red and yellow take turns dropping pieces from the top of a column. Pieces fall to the lowest empty position due to gravity. The first player to connect four pieces in a row — horizontally, vertically, or diagonally — wins. A full board with no winner is a draw.
Controls
• Click any column to drop a piece into the lowest empty slot • Keyboard: use ←/→ arrow keys to select a column, Enter or Space to drop • Pieces cannot float — they must land on existing pieces or the bottom • vs AI / 2 Players: switch in settings • Undo reverts the last move • Red moves first
Tips & Strategy
• Prioritize the center column — it offers the most connection opportunities • Watch for defense: block your opponent's three-in-a-row promptly • Build "double threats": create two four-in-a-row opportunities simultaneously • Avoid dropping above your opponent's three-in-a-row (it completes their four) • Easy AI is good for learning; Hard AI calculates multiple moves ahead
