How to play Four in a Row
- Take turns dropping a disc into one of seven columns. It falls to the lowest empty space.
- Connect four of your discs horizontally, vertically, or diagonally to win. A full board without a winner is a draw.
- Play against three bot difficulties, pass the device between two players, or create an online room and share its link. Find opponent matches you with another waiting player.
- Online moves are checked by the server. Both players must press Play again for a rematch; the starting player alternates. Leaving or disconnecting clears that online board.
- Tap a column or its arrow to drop. Keyboard users can Tab between the seven arrows and press Enter. Undo is available in bot and same-device games.
