PIKKPAKK
Copyright (c) 1977 László Nagy
The game is played on the following board with this setup:
TURN - On each turn, each player push the whole row or column of stones in which his stones outnumber the opponent stones.
A push is not valid if it pushes a stone off the board.
- GOAL - Wins the player that surrounds (orthogonally) the red stone with four of his stones.
Some notes found the ZRF file: The more opposing balls you can drive out to the edge of the board (into a passive position) the less rows will there be where your opponent’s balls outnumber yours
An example If Black shifts down the e column, White can win in 2 turns. He shifts down column d. Then Black can only shifts up column e, which the reply left shift of row 5 gives a win to White.
The author was impressed by the Rubik’s Cube at the time and looked for a playable competition goal for the collective movement of balls (virtually for rotation around field points or the shifting of rows). There's a ZRF to play PikkPakk.In the Mini Játek Mester, a Hungarian mini-book with many rules of abstract games, by László Nagy, we can see what seems to be a variant:
The translation:
The winner is the one who puts 8 neutral (in the figure: dark grey) balls onto the board. See the starting position in the figure.
In one step, rows of continuously touching balls move one position, independently of how many balls they consist of.
1. The color of the piece at the given ball row's edge determines which player can move it.
2. A row cannot be pushed in such a way that by pushing, one's own piece falls off the board.
3. A row cannot be pushed back if it was moved in the previous step (by the ball on the other side of the row) without an opponent's hit.
The arrows in the figure show the legal pushes.
(X): A ball cannot be pushed out from within a row!
If white pushes vertically, then black cannot push it back, but if black pushes forward, then a white piece will fall off and then it can be pushed back.
