In an uncharted land after a long ice age, players take on the role of one of four tribe leaders setting out to cultivate this mysterious land using the power of spirits. For the prosperity of your tribe, connect the altars left behind by ancient civilizations with pilgrimage routes and deepen your faith in spirits. But be careful of the rival tribes! They may get in your way while taking advantage of the paths you've already built! Animism is a pen and paper game where you write on your sheet but also other players’ until the game ends. During the game, each player simultaneously fills in a space on the sheet they receive, then passes it to the next player. Players fill in the sheet they receive with polyominoes of his or her own color aiming to connect the altars scattered by creating a pilgrimage route. The resources (the power of spirits) needed to purchase polyominoes can be obtained by neighboring routes with other players, but at the same time, there is a risk that your route will be blocked. Try to get the highest score by connecting many altars on your route while trying to be adjacent to other players' routes appropriately. The winner is the player with the highest total score on all sheets.
