I am trying to identify a game from presumably the 80s. It was played with at least two players. Each player could set "balls" or "chips" on a 2 dimensional gameboard.
The balls or chips could be stacked, this stacking had a direct effect on adjacent chips set by the other player.
If e.g. 4 balls were set, the chips north, south, east and west got the player's color, the ultimate goal was to kick all opponents by transforming their stones.
