Summon the Great Old Ones by having them align their bodies over Arkham.
In the gameA'Writhe: A Game of Eldritch Contortions, players gather in teams of two. Each team consists of a cultist player and a Great Old One player. The cultist is assisting the Great Old One and attempting to summon them to our plane. To do this, the cultist instructs their deity, with great veneration, to place an appendage on top of an Arkham landmark to complete a specific pattern. The problem is that it is nigh impossible to have one Great Old One form this pattern by itself; that's why if another deity is touching any parts of your pattern, you can use that appendage to complete your own pattern!
Up to three teams of two can play in this contortionist battle of positioning.
