What is Connect Four?
Connect Four is a classic two-player strategy game where players alternate dropping colored discs into a vertical grid, trying to align four pieces in a row before their opponent. It's deceivingly simple—basic rules take 30 seconds to learn—yet offers surprising depth. Strategic positioning trumps luck, making it ideal for quick competitive matchups. This online version connects you with friends instantly using room codes.
How to Use
Create a new game room or paste a room code your friend provides. The 7-column, 6-row board displays on screen. Click any column header to drop your disc into that column—pieces fall to the lowest available position due to gravity. The board shows whose turn it is and highlights the last move. Your opponent sees changes in real-time. The game automatically detects when someone wins (four in a row horizontally, vertically, or diagonally) and declares the winner.

Tips & Insights
Control the center columns; they offer the most winning possibilities because pieces can align in multiple directions. Think in advance about your opponent's threats—often blocking is more valuable than building your own four-in-a-row. The classic opening move should dominate the center, not the edges. Recognize "fork" situations where you create two winning threats simultaneously, forcing your opponent into impossible choices. Psychological play matters—appearing to pursue one strategy while building another can deceive your opponent.
