Flying over the fabled mountain range the Roof of the World, your plane suddenly went down. Luckily, you were on your way to have an expedition in the mountains and your supplies were not ruined in the crash. Unfortunately, you have no idea where you are, or how far it is to civilization. Your expedition has started earlier than expected!
At the start of the game you draw between two to four goal cards to try to complete as you journey through the mountains. You also start with two items, either the rope or telescope, or the compass or map. Place a mountain token at the 10 spot of the fatigue tracker.
Now you are ready to explore the mountains!
At the start, draw a Mountain card from the bottom of the Mountain deck. This is the starting mountain, where you crashed. You do not have an Encounter on this card, so ignore the dice shown at the bottom of it. Then draw a Mountain card from the top of the Mountain deck and place it to the left or right of the starting card.
Each time you move to mountain, roll two dice. You are trying to either get your dice to match, or equal the dice on the bottom of the card. Then flip the card over and read the Encounter linked to the number of successes you rolled.
The game continues until you win by reaching all your goals, or you lose as your fatigue reaches 0.
