01 · 3D CONTROLS

Separate layer turns from camera movement.

Drag a colored sticker to turn that layer. Drag empty space to orbit the camera, and use the wheel or a pinch gesture to zoom. Reset the view whenever your front and top references become unclear.

Start with round trips rather than full solves: perform R and then R-prime, or follow one corner through the four-move right-hand trigger.

02 · PRACTICE & TIMER

Repeat the same sequence from scramble to review.

  1. Reset and apply a fresh scramble.
  2. Inspect for a consistent amount of time.
  3. Start with the button or Space and let solved-state detection stop the timer.
  4. Write down one long pause or reversed move.

03 · TROUBLESHOOTING

Start from the visible symptom.

Return to the last checkpoint you know was correct. Read both colors of an edge or all three colors of a corner before deciding whether the problem is its location or orientation.

01The white cross is visible, but the side colors do not match.

CHECK & RECOVERThe second color of an edge was ignored. Raise that edge, align its side sticker with the matching center, then turn that face 180° back down.

02The white face is complete, but a first-layer stripe is broken.

CHECK & RECOVERA corner is in the wrong location. Read all three colors, remove it to the top, and insert it where those three centers meet.

03A middle-layer algorithm breaks the first layer.

CHECK & RECOVERA turn was skipped or reversed. Compare U with U' and R with R'. Reverse remembered moves; otherwise rebuild from the last reliable checkpoint.

04The yellow-cross algorithm produces an unexpected shape.

CHECK & RECOVERJudge only the four yellow edges. Hold an L toward left and back or a line horizontally, then finish F R U R' U' F' without changing the front.

05Only one edge appears flipped at the end.

CHECK & RECOVERThat state is impossible with legal 3×3 turns. Recheck every piece; reset the online cube or inspect whether a physical cube was reassembled.

06The timer does not stop or the ranking does not update.

CHECK & RECOVERCheck all six faces, then restart in this order: reset, new scramble, inspect, start the timer, solve. Ranking accepts only verified fresh-scramble solves.
