Shamrocks Solitaire card game
The Shamrocks Solitaire layout contains 18 building stacks, which accept cards in both ascending and descending rank regardless of suit. However, a stack can accept no more than 3 cards and removing all cards from a stack takes it out of play.

All stacks in the layout except for those in the leftmost column are building stacks. A building stack accepts cards in both ascending and descending rank. No cards can be added to a building stack if the stack contains 3 or 0 cards. The stacks are arranged so that a king will be below all cards with the same suit as the king.
