Zooloretto
Zooloretto is a board game designed by Michael Schacht, published in 2007 by Abacus Spiele and in English by Rio Grande Games. The premise of the game is that each player is the owner of a zoo, and must collect animals in order to attract visitors to their zoo (thus scoring points to win the game). Having full, or nearly full, animal enclosures scores more points. However, if a player has too many animals such that they must be stored in their "barn", this causes them to lose points. Vending stalls also offer a means for players to score points with enclosures that are not full.
The method that players use to collect animals is based on the mechanics of the card game Coloretto (also designed by Michael Schacht).
