Players build a dinosaur zoo by installing fences in a large area where dinosaurs are roaming freely.
Each player has a sheet with a grid. There is also a stack of cards in the middle of the table. At the start of each round, a player flips open the top two cards from the stack, revealing two numbers between 1 and 6. These two numbers determine the size of a rectangular fence that must be added to your grid (2 x 4 squares, for instance, or 6 x 3). The rectangles separate the dinosaurs and visitor centers into different areas. The goal is to isolate the dinosaurs from one another. As soon as a dinosaur or visitor is alone in an area, you score points. There are also different task cards on the table that can yield additional points.
As soon as the stack is empty (15 rounds), players compare their scores. The player with the highest score wins.
