On an uninhabited island in untraveled seas, explorers have discovered traces of a great civilization. Now you will lead an expedition to explore the island, find abandoned artifacts, and face frightening guardians, all in a quest to learn the island's secrets.

Lost Ruins of Arnak integrates deck-building and worker placement for a game of exploration, resource management, and discovery. Along with traditional deck-builder effects, cards may also be used to place workers, and new worker actions become available as players explore the island. Some of these actions need resources instead of workers, so creating a solid resource base will be key. Players are limited to only 1 action per turn, so make your choice wisely, what action will benefit you most now? And what can you manage to do later, assuming someone else doesn't take the action first!?

Decks are small, and uncertainty in the game is largely mitigated by the wealth of wise decisions offered on the game board. With a variety of worker actions, artifacts, and equipment cards, the set-up for each game will be different, helping players to explore new strategies to meet the challenge.
