Haggis, is a climbing game in the same family as Zheng Fen and Big Two. It borrows and recombines elements from its parent games (card combinations, bombs, scoring for cards in hand, scoring for cards collected in tricks) and mixes in equally distributed wild cards and betting that you'll be the first to empty your hand of cards.
I revised the rules posted by the publisher to include all the various clarifications that have been made in BGG forum discussions. These include the alternative scoring for 3 players. I introduced some new terminology (e.g., "shepherd") to make it easier to explain certain concepts.
