Animal Upon Animal: Crest Climbers uses the same basic gameplay as Animal Upon Animal: Each turn a player rolls the die and either places one or two animals on to the stack of animals; passes one of their animals to another player for them to place; or places an animal on the table; extending the base for other players to build upon. Of course; if any pieces fall off whilst you are building; you get up to two of them back. The first player to have used all of their animals wins.
