Ultimate TicTacToe: game rules
Ultimate TicTacToe
🎯 Goal: Claim three local boards in a row, column or diagonal on the big 3×3 grid.
🔲 How it works: Players take turns. You win a local board classically with three marks in a row.
➡️ Forced board: The cell position of your move decides which board your opponent must play in. If it's already won or full, they may choose freely.
🏆 Winner: The first to hold three local boards in a row wins the game. It is a draw once every board is decided – or earlier, as soon as neither side can still complete a row.
Settings & scoring
💡 Good to know: The first move is free, the starting player is drawn by lot. As in the other board duels you can offer a draw or resign.
🪑 With two players you face each other at a wooden table in the lobby: you always at the bottom, your opponent at the top, the game already laid out in the middle. An empty chair reads “Seat free” – you copy the invite link at the top next to the code.
🔁 After the game either of you can offer a rematch – it starts as soon as the other accepts. The colours swap, and whoever did not open the last game moves first.
