Phones join with the 4 letters on the TV (or the QR code) and name their pile. You start with 14 people in your color: guys and girls, and they're good at different things. BIG GUYS hold the bottom of the stairs. HEAVERS throw farther. FLYERS fly farther and catch ledges. CLIMBERS climb fast. HUNKS and BOMBSHELLS lure people away from the other piles.
Sideways runs. UP makes them climb on each other into stairs against whatever's in front of them (more people, taller stairs). DOWN makes everybody hang on.
Throws somebody (a flyer if you've got one) where the stick points. If they catch a ledge, everybody else grabs ankles into a ladder (or a bridge over a gap) and climbs up it, and then the ladder pulls itself up. Anybody already over a wall reaches down and does the same.
Strays are standing around everywhere: bump into them and they're yours. FLAUNT and they come running, and anybody from another pile touching yours might switch sides. Sit on another pile long enough and the people underneath are yours (DOGPILE).
Black Friday, the mosh pit, the pool party, then THE WALL (the soup rises). The first pile to get somebody to the top starts the doors closing: 25 seconds. Everybody up there is a point, and they're your pile for the next course. Fall behind the left edge and they're left behind. And look out for the big hammer.
Everybody standing on something hops, the front of the pile first, so it rolls back through them like a wave: over a cart, up a step, across a little gap if you're running and feeling brave.
