In Les pierres de Coba - a solo, narrative and evolving game - you will perform 50 challenges to restore balance in Mayan society thanks to the 9 sacred stones (9 carved dice). Each of your stones represents a member of Mayan society, and for each challenge, you will need to divide your dice into two groups of equal value. But the dice faces have powers that will change their value or that of their neighbors depending on the situation. You will discover your quest through a 56-page adventure booklet, which will present you, with each challenge, a legend linked to the universe of Mayan society. —description from the publisher
