Altitude is a card game about mountain in winter. The goal is to build the highest mountain with numbered cards. The mountain is pyramidal (we can play a card upper only if its number is higher than the other two cards under). At our turn, we draw a card, and play it on our mountain or the opponent's mountain. Or keep it in hand by playing a card in our hand to our mountain. There is numbered cards, some with animals (victory points) and some avalanche cards we can prevent with savers or cable car. We score points with the height, animals on our mountain and savers kept in hand at the end.
