'Countdown Queens' is like normal chess with one exception: Each queen can make at most 7 moves in the whole game. The red or white number in a queen shows her remaining mobility.
 
Zillions is not so strong in this game, because it often realizes too late that its queen can make only 7 moves. Even human players with Elo rating 1700 have good winning chances against Zillions when they keep the position quiet and patiently wait for Zillion's queen moves...

The user can generate other starting positions by substituting the Queen7 by other queens, for instance by a Queen3.
