5.15 is a rock climbing card game for 3-5 players that plays in about 45 minutes.

In 5.15, you take on the role of a rock climber. First, pick your style: boulderer, trad, sport, or alpine. Then challenge yourself on easier climbs, from 5.6 to 5.14, as you build up strength and collect gear with your partners. When you are ready, head out to the crag to become the first climber to succeed on a 5.15, one of the hardest climbs in the world!
