The Emperor Penguin looooves jewelry!

In Jewels for the Emperor Penguin, each player takes charge of a five-member penguin guild that must scale the icy walls of the Valley of the Emperor Penguin, gathering gems — emeralds, rubies, sapphires, and diamonds — and making advantageous exchanges to acquire the specific gem-recipes needed to claim objective cards that represent the fantastic jewelry the Emperor Penguin covets.
