Endless Winter is a euro-style game that combines worker placement and deck building in an innovative way. Each round, players send their tribe members to various action spaces, and pay for the actions by playing cards and spending resources. Tribe cards grant additional labor, while Culture cards provide a variety of unique effects. As an alternative, cards can be saved for an end-of-round Eclipse phase, where they are simultaneously revealed to determine the new player order, and trigger various bonus actions.

The game features a novel blend of interwoven systems and mechanisms, such as multi-use cards, area influence, tile placement, and set collection. Plus, there are many viable paths to victory. After four brisk rounds, scores are tallied, and the tribe with the most points wins!
