Eldur is a cooperative game for 2–4 players, ages 8 and up. Players must work together to evacuate the island before the active volcano takes control.

There are 4 helpers that players cooperatively activate to fulfil the task; the Gatherer seeks goods, the Herder searches the mountains and hidden valleys for sheep and the Seeker looks for lost families. All of them are safely transferred to the harbours where the Knerrir sails them to safety on the newly discovered island.

However, the volcano is unpredictable; no one knows where the lava will flow. Ash falls, cracks, or new fissures may open at any time, making no place safe. The challenge is to see whether the humans can complete their evacuation or if the volcano will regain control of the island.

Which side will prevail in the end?
