Step-by-step solution
- 1) Skip the exposed Red and Black pieces for now and hunt for Blue first, since the opening bottom Box calls for it.
- 2) Tap the front-left Pink marble to park it on the belt; that clears the way to the Blue marble sitting right behind it.
- 3) Grab that newly exposed Blue and drop it into the first bottom Box to start it filling.
- 4) Clear the front-left Brown marble into its bottom Box, then employ the exposed Black and Red marbles to set up matches against the frozen right side and crack the Iced Boxes.
- 5) Once the ice breaks, take the Purple marble that was hidden behind it and drop that Purple directly into the third receiving Box.
- 6) Once that opening row of receiving Boxes is done, open the left Mystery Boxes but check each revealed color against your Boxes, and keep at least three empty belt slots before poking another one.
- 7) Clear the single Key Box tucked in the top-right corner to spring the golden lock, freeing the four keys of Light Blue, Green, Pink, and Orange near the top.
- 8) Feed the freed Light Blue and Green keys into their open bottom Boxes first to finally clear the board.
