How to win
Take turns dropping discs into one of seven columns. A disc falls into the lowest empty position. Connect four of your discs horizontally, vertically or diagonally before your opponent does.
Play online with a friend
Choose online mode and create a room. Copy the invitation or use Challenge a friend. Your friend can open the link or enter the room code. Both language versions connect to the same server and can join the same room.
Rematches and daily goals
Play a rematch after a win or draw. The game tracks scores and winning streaks and offers a daily goal. A room needs both players connected for online moves. A network interruption can stop play; keep the room link to hand.
Local play and privacy
On one device, take turns using the same board. Local records belong to your browser. Online mode sends moves and player names to the game server so both players see the same board; no account is required.
