Race to the top of the mountain using counting and addition but watch out for yetis who will chase you back down again! Players take it in turns to turn over two of the footprint shaped cards. If two number cards add up the numbers and move up the mountain that many spaces. If one card reveals a yeti then you move down that many spaces instead. If it's two yetis then everyone moves down two spaces. If you are still in the meadow you are always safe from the yetis.
