The method that players use to collect animals is based on the mechanics of the card game Coloretto (also designed by Michael Schacht).

These include extra animal enclosures, a petting zoo, restaurant, souvenir shop, and pavilions, each of which offers different opportunities for players to score points or money.

An additional large expansion, Aquaretto, can be played as a stand-alone game or in combination with Zooloretto.

An iPhone and iPod Touch version was developed by Spinbottle games and published by Chillingo in May 2009.

[1] Zooloretto for PC (including digitally via Steam) was developed by White Bear Studios and published in 2011.
