Drop pieces to connect four of your color in a row — horizontally, vertically, or diagonally — before your opponent does.
Controls
- Tap/click a column to drop a piece into it
- Use Left/Right to choose a column, then Enter or Space to drop. Keys 1–7 also drop a disc while a column is focused.
- Coral stars go first. Gold rings go second. Switch to Two players to share the board.
