1. You receive a start event when a second player joins, which includes your sign ('x' or 'o').
2. You regularly receive a board event, which includes the current state of the board.
3. You receive a turn event, which includes the next sign to be placed.
4. When it is your turn you can send a mark event with the row and the columnn (zero based), which should be marked with your sign.
5. When the game is complete you will receive a game_over event, which includes which player wins and which fields form the winning row. Otherwise go to 3.
6. You will receive an invalid_action event when you try to do something that's not allowed like marking an already marked field.
