Step-by-step solution
- 1) Start by poking the Light Blue marble on the far left plus the Light Blue sphere near the center of the upper Tray, sending both into the two Light Blue boxes lined up on the right.
- 2) Pick the Dark Green marble that sits one step in from the left so it lands in the far-left Green box, then grab the Dark Blue marble three from the right to empty the Dark Blue box in column two.
- 3) Leave Brown, Bright Green, and Orange alone for now, because touching them jams your Conveyor Belt before the keys can fire.
- 4) Clearing that front row drops the boxes, activates the two keys, and snaps the central lock open to free the middle column.
- 5) Send the solid Purple line parked over the left x2 Multiplier Gate so it doubles into the lower Purple box, then do the same with the White marbles over the left gate.
- 6) Once those boxes edge forward and become reachable, release the Brown marble that started on the bottom row, and pull the Orange marble off the far right.
- 7) Reveal the Mystery Box sitting at the top of the center column one tile at a time, matching each color it shows to a live box, and avoid flipping all three at once.
- 8) Match the leftover Yellow, Orange, and Pink cluster on the right wing plus stray Blues to the remaining boxes, keeping belt slots open to finish clean.
