- Object: Form a single stack of all cards.
- Play: A player may move (i.e. flock) one stack of cards onto another stack of cards in the same row or column if the cards on top of both stacks have either
- the same suits, or
- the same or adjacent ranks. Aces are low and not adjacent to kings, so rank adjacency is according the ordering A, 2, 3, ..., J, Q, K.
