ATTRACT

Copyright (c) 2005 Jaroslaw Cichocki

This game is played on an empty NxN square board (say 8x8):

 

TURNS - At each turn, each player must do the following actions: First, drop a friendly stone on an empty cell; Second,  all pieces in the same horizontal and vertical rows move one cell nearer to the placed piece, if possible. GOAL - If at the end of the move, there are any pieces that have an enemy piece at each diagonally adjacent cell, 4 in all, then the player with the most such pieces wins. If these numbers are equal, the game continues.

 

An example White's turn. He plays at [1] attracting four different stones (check next diagram), and by doing so, he wins by making one winning pattern (the marked stones) while Black does not have any.
