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.
Check Jaroslaw's website for more detailed information.
Since the site is defunct, I copy-paste some of the author's words about the game:
Principles of logical game "JC Attract"
1. The game is intended for two players and is played on board 8x8 (or 10x10, or 12x12, or 14x14, ...).
2. Each player has 32 (or 50, or 72, or 98, ...) own pieces (white or black).
3. Every move is divided into two stages:
- The player places own piece on the board on free field.
- The player pulls near to placed piece all other pieces in the same horizontal and vertical rows step by one field. The player has to pull pieces in order started from placed piece. The player can pull this piece who can be pulled on free field.
4. The winner is one who: Will be first to have more of own pieces winning. A winning piece is one surrounded by four of the opponent's pieces as seen in the exemplary drawing.
