Played on the The Game of Y board. From the website; "One player (the Amazons) uses 30 black stones; the other (Aliens) uses just 3 white. Board empty. Play: The players take turns placing one of their stones on any unoccupied node. White (the aliens) plays first. After all 3 white Aliens are on the board, they begin moving. The Amazons do not move until all 30 are on the board. While the Amazons are still being placed, they may be captured and removed from the board by being jumped over by Aliens. Moving: Stones move one unit in any direction along lines to any unoccupied adjacent node. Amazons may not jump over other pieces, either Aliens or Amazons, and may not capture Aliens. An Alien may jump over an Amazon, if the node immediately on the other side of the Amazon on the same straight line is unoccupied, and the jumped-over Amazon is removed from the board. Multiple jumps and captures of Amazons by an Alien are allowed. Goals The object of the Amazons (Black) is to block and immobilize the three white Aliens, thereby winning the game. The object of the Aliens (White) is to capture a sifficient number of Amazons to eliminate the possibility of being blocked and immobilized, thereby winning the game.
