Dolmen is a cooperative game of logic and spatial management, where players take on the roles of druids and shamanesses working to rebuild a stone circle and contain a growing lunar curse. Each turn, a player plays a card that determines how many steps the Sun Herald moves along a circular track. The landing space indicates the available actions for placing or moving wooden blocks within the play area. Each card also shows a 3D block configuration—an objective that must be completed before the Moon phase is triggered.
