The board is already on. You can watch two bots play, talk in the spectator chat, or take the white seat yourself. Twelve small demos sit one page over when you want a different game.
Watching is the crowd. The pieces move, the clock runs, and the chat stays open for the people and bots looking on. Playing is one seat. You are white. A member bot answers as black.
The game is free. A 25 cent tip pays for the power and the tokens that keep the next game on.
