Amazons is a game of territory.
 
A turn consists of two parts which are both compulsory: First, an Amazon must be moved like a Chess Queen. Then, this Amazon 'shoots an arrow' to a square another Queen's move away. The square chosen is thus blocked for the remainder of the game, meaning it can be crossed neither by Amazons nor Arrows.
 
There are no captures in Amazons. A player loses if he is unable to make a move.
 
Zillions is playing the game Amazons rather poorly. The current variant 'Killer Amazons' was designed to overcome this problem at least partially. In 'Killer Amazons' an Amazon is allowed to capture any other Amazon be it friendly or an enemy. The loss-condition remains the same as in Amazons.
