Attention

\n\n

Speed and Time-out

\n\nKeep in mind that the avg speed of one game is 2.5 moves per 24 hrs per player. Since the Round Robin will activate several gamess at the same time, for a match with five players, the avg speed is 10 moves per 24hrs. To avoid losing by time out, the safe way is to play faster than the avg speed. Loss by time out will affect your reputation in this Match system — such as disqualification and/or demotion to a lower level.\n\n
