- Goal: The players' goal is to unite all their pieces regardless of stack-height in one orthogonally connected group that must outlast their opponent's next move. If on the next move the opponent can split it, the game goes on.
- Draws: If, after one player unites his pieces, the opponent on the subsequent turn also unites his pieces, then the game is won by the player with the larger group (counting stacks as one). If both groups are of equal size then the game is a draw.
If a move simultaneously unites a player's group and the opponent's group, then the same applies: the larger group wins and equal groups draw.
