Crystal Cave-In

Played with 2-4 players (up to 8 players with both expansions), players race to explore an expanding cave system to collect crystals for the Queen Exthera. Players roll a D6 to determine the number of actions they get on their turn. Actions include moving, digging, stealing, and causing cave-ins. The map is built using cave cards, as a player moves to the edge of a cave they will flip over the next card in the deck, being able to orient the cave as they see fit. The layout of the cave will change every game! The objective is to explore and be the first to escape with 2 crystals, but beware, as you can only carry one crystal at a time, you can't mine the same crystal source twice, and other players will try to out maneuver you to steal your crystal for themselves. —description from the publisher
