Why it works
A single cube and consistent orange/blue diagrams make the A/B dilemma readable by 0:54, despite 33.3 cuts per minute. The apparent answer at 2:03 is challenged at 2:46 by drawing the cube's movement piece by piece. A gameplay proof insert at 3:30–3:37 coincides with the top replay peak at 3:32.5–3:35.6.
