Welcome to Open Sesame: a press-your-luck card game of high-stakes memorization and deduction by world-renowned game designer and multi-Spiel des Jahres winner, Antoine Bauza (7 Wonders, Takenoko, Tokaido, Rampage, Hanabi). Players take turns alternating between the role of Ali Baba or one of the thieves guarding the Cave of Treasures. As Ali Baba you’ll steal treasure from the cave until you’re trapped or you flee, and as the thieves, it’s your job to carefully observe and recite exactly what it is that Ali is attempting to escape with. Open Sesame, which also features delectable, eye-catching art, is light-hearted fun perfect for treasure hunters of all ages!
