Eruption is a competitive survival game in which each player struggles to save his or her own village from destruction caused by an onslaught of lava from an erupting volcano. As lava enters a village, its temperature increases until it has burned up completely. Players can protect their own villages by placing lava tiles defensively and strategically building walls of various materials to hold back the lava. They are also rewarded with action cards for directing lava to other villages. Action cards allow players to rotate, replace, or remove the hexagonal lava tiles as well as cool down and fortify their own villages. Once the volcano has fully unleashed its fury, the player whose village is at the lowest temperature wins.
