The game is drawn automatically if there is no winner after 200 moves (100 each).(quote from the rules)...

you could put less movements for autodraw if possible,
because, there the Bullet Room when it comes late in the game some pieces left over, example: (2 pieces Both players) and is very annoying moving the piece all the time, when your opponent doesn't accepts the draw never, and wants to win over time.
if you can change that I thank you, thank you.
