The goal of Extinct: The Lost Kingdom playing cards was to explore the prehistoric world of creatures that are long gone. Each card has an origami dinosaur and pip (spade, diamond, clubs, and hearts) illustration. Extensive research was given throughout the process in learning the art of origami and the accurate scientific portrayal of each dinosaur. The back of each card includes the pattern of all the dinosaurs included in the game. It is time to go way back in time to the roaring past and see what is extinct.
