Magneton Rules

An entry in the 2001 8x8 Game Design Competition

Designed by Cerrato Luca
For 2 players

Players: 2, black and white
Board: 8x8 Chess board
Stones: 12 black and 12 white
Object: Be the first to create a line of 4 stones in a row
Initial Board: The board is initially empty

Where to Put the Stones: The stones, during the game, are put on the empty squares.
Who Starts: The white player starts the game by dropping a piece of his color wherever he desires on the board.
Second Move: In the second move, the black player drops a piece of his color wherever he desires on the board.
Magnetic Effect: After the second move every stone must cause the "magnetic effect."

The "magnetic effect" involves the drop stone and the stones that are in line with the drop stone, with the line started by the drop stone in the eight possible directions (2 horizontal, 2 vertical and 4 diagonal). Only the first stones that these lines (magnetic lines) meet are involved in the "magnetic effect."

Example:

8 . . . . . . . .
7 . . x . . . . .
6 . . . . . . . .
5 . . o . . . . .
4 o . . . x . . .
3 . . X . . . . .
2 . . . . . . . .
1 o . . . x . . .
  A B C D E F G H

The drop stone is in C3 and the stones involved in the magnetic effect are A1, E1 and C5. The stones in A4 and E4 are not in line with C3. The stone in C7 is not involved in the magnetic effect because it is not the first stone in the magnetic line (the first is C5).

Actions Caused by the Magnetic Effect:

  • Any stones the same color as the drop stone are sent away in the magnetic line direction. This movement finishes when the stone meets another stone or the edge of the board.
  • Any stones of the opposite color of the drop stone are attracted in the magnetic line direction. This movement finishes when the opponent's stone meets the drop stone.

Example:

8 . . . . . . . .
7 . . . x . . o .
6 . o . . . x . .
5 . . . o . . . .
4 . . . O . . . .
3 . . . . . . x .
2 . . o . . x . .
1 . . . . . . x .
  A B C D E F G H

The drop stone is in D4. After the magnetic effect the situation is:

8 . . . . . . . .
7 O . . x . . o .
6 . . . O . . . .
5 . . . . X . . .
4 . . . O . . . .
3 . . . . X . x .
2 . . o . . . . .
1 . . . . . . x .
  A B C D E F G H

No More Stones to Drop: When there are no more stones to drop on the board, the players move the stones on the board.

  1. Stones are moved with respect to the "magnetic effect." (See example below)
  2. After the move there is a magnetic effect.

Example:

8 . . . . . . . .
7 o . x x . . o .
6 . . . o . . . .
5 . . . . . . . .
4 . x . O . . . .
3 . . . . x . x .
2 . . o . . . . .
1 . . . . . . x .
  A B C D E F G H

The stone in D4 can move in D1, C4 and A1. The effects of these moves are:

8 O . . . . . . O
7 . . x x . . . .
6 . . . O . . . .
5 . . . . . . . .

Legal Victory: A line of 4 stones is a valid victory if the fourth stone of the line is pushed by magnetic effect and not dropped or moved by the player.

Example:

8 . . . . . . . .
7 . . . . . . . .
6 . . . o . . . .
5 . . . o . . . .
4 . . . O . . . .
3 . . o . x . . .
2 . . . . . . . .
1 . . . . . . . .
  A B C D E F G H

If the O stone is dropped in B3, the victory is valid. The victory is not legal if the O stone is dropped in D3 or moved from C3 to D3.
