Obstacles placed in the alpiner's way include falling rocks, wild animals, trees, and brush fires that they must avoid to continue up the mountain. In level 7 the avalanche obstacle is introduced and in level 13 the ice falls. Being hit by obstacles will result in sliding down the mountain, some further than others. If the alpiner slides all the way down the mountain one of the lives are lost. Players receive an additional life every time they make it to the top of Mount Everest.
