8. FAQ

  • What do the time controls mean?
    Time controls are telling you how much time you have for each game.

    For example, G90+30 means game in 90 minutes with a 30-second increment with each move. This means you get 90 minutes, your opponent gets 90 minutes, and with each move players get an extra 30 second on their clock. 
  • How many games/rounds?
    The 6SS before the time control means there are six rounds or four games a player can play in the tournament. The tournaments are never elimination, so win or lose you can stay in the tournament.
