Lost Ruins of Arnak combines deck-building and worker placement in a game of exploration, resource management, and discovery. In addition to traditional deck-builder effects, cards can also be used to place workers, and new worker actions become available as players explore the island. Some of these actions require resources instead of workers, so building a solid resource base will be essential. You are limited to only one action per turn, so make your choice carefully... what action will benefit you most now? And what can you afford to do later... assuming someone else doesn't take the action first!?
