Step-by-step solution
- 1) Leave the four huge front blocks of Orange, Light Blue, Yellow, and Purple untouched for now and tap the lone Pink, Green, and Purple marbles sitting above them.
- 2) Dropping those center marbles flips the neighbouring grey question-mark tiles, revealing the colors needed to stock the Dark Green, Purple, and Pink receivers below.
- 3) Keep the belt as empty as possible while digging through the Hidden Boxes to knock out a few of the front lower receivers.
- 4) As you clear Hidden Boxes near the middle, nearby drops trigger the two blue Gift Boxes, which swing open to spill fresh playable marbles across the board.
- 5) Once Orange and Light Blue receivers push to the front in columns 1, 2, and 3, it is finally safe to poke the huge Light Blue 9-marble block, which flows into the waiting boxes without jamming the belt.
- 6) Do the same with the massive Orange block to clear the second demand wave.
- 7) With the front blocks gone, shove the huge Yellow block from the front to wipe out the Yellow-packed back row of receivers all at once.
- 8) Finally, pair the remaining Green and Purple marbles spilled by the Gift Boxes with the last receivers in column 4 to finish the level.

Frequently Asked Questions
What is the main trap to avoid in Level 391?
The biggest mistake is tapping colors that have no active bottom Box yet. They park on your Conveyor Belt and burn limited slots, so clear the shades that actually have receivers first.
How should I open Level 391?
Ignore the upper layers and aim at the bottom row of the Top Tray. Feed the colors that already have open boxes, then work upward once the lower lanes shift.
When does the midgame color change happen in Level 391?
After the opening boxes fall, the lower columns swap what they demand. Watch for the new shades and only pull blocks that match a box sitting at the front of a lower lane.
Any tip for finishing Level 391 clean?
Keep at least a few empty belt slots before poking mystery or hidden boxes. Feed a revealed color the moment it matches an active box, and fall back to visible marbles when the belt gets tight.
