In Idle Arks Build At Sea, you can create your own ark. Your task is to drift on the sea and ensure your survival, while saving other survivors, rebuilding cities, and exploring unknown civilizations! By swimming to collect wood, floating bottles, and treasure chests, you can create and craft more advanced resources, and explore new lands in all possible ways, use your imagination and creativity, and expand the width and height of the raft for free. There are also many upgrades for fishing and storage space expansion that will help you survive at sea. The game has more than 100 free building materials and locations waiting for you to unlock, build and upgrade your raft to survive at sea.
