Exercise 1: branch tracking
Pick one cube as the anchor and follow the order of branches from that cube outward. This is the fastest way to stop relying on silhouette alone.
Exercise 2: top-cube prediction
Before the shape turns, name which cube is on top. After the turn, ask where that same cube should land. This builds a more explicit mental model of orientation change.
Exercise 3: mirror rejection
Look for one branch that would reverse order if the object were mirrored. In exact-match mode, this lets you discard distractors quickly without having to compare every cube.
Exercise 4: axis-turn drills
Use rotation-cue mode and treat each prompt as a separate drill. X-axis prompts train side-to-side turns, Y-axis prompts train depth changes, and Z-axis prompts train flat-plane spins.
Exercise 5: speed consolidation
Once one drill becomes reliable, shorten the timer slightly while keeping the rest of the setup fixed. That turns a slow but correct strategy into a fast one without changing too many variables at once.
