However, before that can happen you must populate the map with your trolls and strategically position them around the legendary rocky forts of the mountain ghost..
You strike the tower with the hammer, trying to knock out some rubble of different colours in order to collect the most valuable treasure tokens. But be careful! Do not knock out more rubble than your capacity allows, which is determined by the number of trolls you have around the cave. Although, there is some luck involved in the game, you may be surprised how much you are able to control. Through tactical placement of your trolls you may even join in on other players excavations, freeloading off their hard work.
The decisions are made on the time track surrounding the game board. This time track introduces a novel system, consisting of two types of fields, which creates interesting and important decisions for the players: Either you move on the placement fields (for placing trolls on the board) or on movement fields (for moving trolls on the board).
