How to do it

Make three small piles of cards: hold types (e.g. crimp, sloper, pinch), movements (e.g. heel hook, drop knee, dyno), and themes (e.g. slow, powerful, balance). Draw one card from each pile and build a boulder on existing wall holds that uses all three. Climb it, tweak it until it flows, then draw again. Aim for 3-4 boulders in the session.

Who it’s for

Sessions where you can’t face another circuit, and for setters who default to the same three shapes. The cards make choices you wouldn’t, which is the entire point.

Common mistakes

  • Redrawing until you like the combination. Take what you draw. Slow, sloper, dyno sounds impossible until you find the one move where it works.
  • Building at your limit. You want to climb the problem several times and refine it, so keep it well below your max.
  • Making the theme decoration. If you drew ‘balance’, the boulder should fall apart when you rush it.
  • Not writing the good ones down. Some of these turn out to be excellent problems. Note the holds.

How to progress

Add cards as you go: hold types you avoid, movements you’re bad at, themes like ‘no matching’ or ‘one foot only’. A pile built from your own anti-style notes turns a game into targeted training.
