Your opponent's clock runs while it is his turn to move. The initial time is the amount of time you start with on your clock, in minutes. The increment time is the amount of seconds added to your clock after each move you make. You can actually gain time on your clock if you move faster than the increment. Green dots are for normal chess Blue dots are computer opponents, either robotic or human operated Grey dots are games that are out of your range or for which you are not eligible to play Red dots are for wild games.
