The object of the Crag was for all three players to race to the peak of the mountain, while hitting a series of actuators (buttons that illuminated a light beacon when pressed) along the way to the peak. If a player misses any of the actuators along the way, a spotter at the top (referred to as the "Crag Troll") prevented that player from completing the climb until he/she returned and activated whatever targets they missed. Each player had a separate, but identical side of the mountain to climb, and was not permitted to cross into their opponents' paths or disrupt their progress. The climb is made more difficult by strobe lights simulating "lightning", foam rock "avalanches", flying "snow" in the form of glitter and confetti, and "nuclear flying crystals" in the form of balls that are each triggered either at random or when the players stepped on specific switchbacks on the crag. The first player to successfully activate all of their actuators, including the final one at the peak, earns 725 points. The second and third-place earn 550 and 375 points, respectively.
