Step-by-step solution
- 1) Leave the Orange and White marbles alone, since neither color has a Box anywhere in the top rows and releasing them would jam the belt.
- 2) Clear one of the two Blue Boxes first: tap the Mystery Boxes in the upper rows until you reveal enough Blue marbles, holding them on the belt until you have all three.
- 3) Once you have three blues, drop them into a Blue Box to empty it, then repeat for the Purple Box using the visible purple marble in the fourth row.
- 4) When the top row fills with colors you cannot use yet, like Red and Yellow, fire the first Rocket Booster to wipe that entire row and reveal five fresh marbles below.
- 5) Shift to hunting Red, Yellow, and Purple among the newly revealed marbles to clear the now-accessible second layer of Boxes.
- 6) Keep the second Rocket Booster in reserve as your emergency button in case the board jams again, and use it on the Iced Red in the fourth row if needed.
- 7) Ignore the solid pillar of four Brown Boxes in the middle until nearly everything else is gone, since chasing Browns early just causes a jam.
- 8) Finish with the pop-it Red, Green, and Yellow marbles, then gather the four sets of Brown and empty the Brown pillar, using the spare rocket to break up anything blocking the final clears.
