A practice tool for the blindfold method taught at jperm.net/bld. Generate a scramble, then walk the cube one cycle at a time to see exactly how memo letters are traced — and in what order everything is solved.
The Solve Order
always the same five beats
01
Memo edges
Trace edge cycles into letters.
02
Memo corners
Trace corner cycles into letters.
03
Solve edges
Shoot each edge letter in order.
04
Parity
Only if both memos are odd.
05
Solve corners
Shoot each corner letter in order.
Edges
Buffer UR · Target UL · Edge swap (T-perm):

Corners
Buffer ULB · Target DFR · Corner swap (Y-perm):

Parity — run once between edges and corners, only when both letter counts are odd

Memorize the scramble, then execute it blindfold. Times are split between memo and execution. Space to start.

Memo Summary
pair letters → images → one story
Edges— letters
Corners— letters
Trace both orbits to check for parity.
Old Pochmann tip: turn each letter pair into a vivid image (QU → "quarry", SR → "Sarah Connor"), then chain the images into one short, ridiculous story. A story sticks far better than 20 loose letters.
Navigation Drill
train the core skill: "where does this piece go?"
The highlighted slot on the cube holds some piece. Without using the trace, work out which slot that piece belongs in, and enter its letter. This is the single move every cycle is built from.
Pick Edges or Corners above, then start a drill.

Pair Flashcards
0 / 0
Flash a letter pair and recall your image. Weak pairs surface more often. Use ← / → after reveal, or Space to advance.
