Step-by-step solution
- 1) Play only the right side at the start, sending the Dark Green receiver down immediately to clear it out of the way.
- 2) Click the Light Pink to park it on the Conveyor Belt, then take the Purple box behind the front row and feed it into the front Purple receiver below.
- 3) To break the Crates, clear exactly three nearby boxes, concentrating your next moves on the red, cyan, and gold receivers hugging them.
- 4) When a Light Pink bottom Box slides up, grab the Light Pink stashed on the belt at once to open up that slot.
- 5) Once the Crates smash open, drop the box carrying the purple key first and then the gold key to finally unlock the left column.
- 6) Feed the Green and Yellow boxes pinned beneath the chains, then move through the six Mystery Boxes one at a time.
- 7) For each Mystery Box, send the color home if a matching bottom Box is ready, or hold it on the belt and seek its match over on the right before pulling the next one.
- 8) Before triggering the two top-left Gift Boxes, confirm at least four belt slots are free, then clear the Mystery Boxes beneath them and sort the revealed colors into your remaining bottom Boxes to finish.
