Pinball Crack is predominantly a hand crack with some corner work; it is interspersed with offwidth as well. Delicate footwork with some balls footholds and a variety of different hand and body jams lift you up the climb. Steep climbing for sure.
Location
Pinball Crack is the middle of the three cracks on Slot Club Wall.
Protection
Rack up to 4". Bring multiples of 1" to 3".
Descent
About 100 feet up the climb you may continue up the wide crack through a bulge and finish as per "The Closet" or you may traverse right under the roof (airy, fun) about 25 feet to the top of a pillar and the anchor for the "Slot Club" route. Rappel from here with a single 70m rope down the face.
The rappel anchor was two fixed nuts with webbing and rings. We rapped down the face with a single sixty and came up short 15'. We might have made the full rap if we went down the Slot Club chimney but that seems doubtful.
Instead of traversing right you can continue up and walk-off west, up stream. I have not done this.
