How it plays
Two players take turns marking a four by four board. The first to line up three in a row, column or diagonal takes the round; a full board with no line is a draw.
What a room adds
- Round after round. A room keeps its two players and a running score, and the opening move alternates.
- Rematch by agreement. A new round starts when both players ask for one.
- Spectators. Anyone else who opens the room's link watches the match.
- No stalling. You can resign a round, and claim it if your opponent leaves.
