Zooloretto is the winner of the prestigious Spiel des Jahres 2007 (game of the year) and is highly rated in boardgaming circles. It is a fun family game based around trying to house animals in your own zoo. Each turn you pick a random animal tile and choose which truck to place it on, then choose a truck of animals to take to your zoon and try to place them in your pens and avoid any overflows. The strategy is all in your choice of truck and knowing what animals to take and when. You can also pay to do other actions such as buy from another zoo, move the animals around in your own zoo and expand your zoo.
The animals are cute (they can even produce sweet babies), the game is great fun. I would recommend from around 9 years old, takes around 45 minutes. Children will love it.
