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.
