  • What do the time controls mean?
    Time controls tell you how much time you have for each game.
    G30;d5: Game in 30 minutes with a 5-second delay with each move. This means you get 30 minutes, your opponent gets 30 minutes, and at each move the clock will count back 5 seconds before the time starts. One game may last up to 1 hour.
