Zooloretto Würfelspiel: Baby Boom is an expansion to Zooloretto Würfelspiel. It adds a few different new features: - Instead of extra points, the reward for filling an enclosure first is an expansion with three more spaces for the given animal. Other players can't use these expansions. - Heart symbols on specific enclosure spaces mark 'parent' animals, and as soon as the second heart symbol is crossed in an enclosure, a baby is born (another cross is added). Lions with expansion may even have two babies. - For money you can still release animals from the barn OR score them for star symbols. There are star symbols on enclosure spaces as well. The more star symbols a player collects during game, the more points they can get (1 star symbol is worth only 1 point but 5 star symbols score 8...) - Also, in the barn only one animal (of the player's choice) can be placed in infinite amount. For further animals of other species other animals' spaces have to be used (thus scoring -2 points for each).
