Black goes first. Take an empty square that traps a line of the other colour between it and one of your own discs, along a row, a column or a diagonal. Every line you trap turns over at once. The squares you can play are marked, and a square that turns nothing over is not a move.

A player with no legal square is skipped automatically, so there is no pass button and the board says whose move it is. The game ends when neither of you can play, and most discs wins. You can resign at any time, which gives the other player the win. Chat is always on at the board, and voice only if the host switched it on when they made it.
