3D Connect Four

Play the classic four-in-a-row strategy game online on a 3D board. Create a multiplayer room and share its code or link with a friend, or play against the AI at easy, medium, or hard difficulty.

How to play Connect Four

The board has seven columns and six rows. Players take turns dropping a piece into a column, where it settles into the lowest open space. Connect four pieces horizontally, vertically, or diagonally before your opponent to win. Plan each move to build your own line or block theirs.
