Step-by-step solution
- 1) Send the central White marble down into the White Box waiting in column two, which clears the center slot and reveals the Hidden Box colors above and beside it.
- 2) Send the Dark Blue marble down into the third column Box, which shifts the board and exposes more of the left side.
- 3) Send the now-accessible Black marble sitting to the left of the center mass into the first column Box, then drop the White from the isolated left-edge stack to fill the remaining White demand.
- 4) Pull only adjacent marbles to tick the bottom blue Gift Box's counter to zero, and when it pops it exposes a fresh cluster of marbles.
- 5) Once the front row clears, target the new Light Blue, Purple, and Black demands, and feed Purple aggressively since your middle and right-side lower Boxes need it most.
- 6) Leave the Red and Pink marbles in the Top Tray until their bottom Boxes move to the front, since the Red Boxes sit buried under Purple and Green.
- 7) Chip at the left portion of the remaining center cluster to uncover the blocks beside the second Gift Box, stopping your dig whenever the belt hits four or five filled spots.
- 8) When the top Gift Box shatters and the back half opens, drop the two far-right Green marbles, feed the Pink marbles into column three, and sweep the remaining Reds into column four to finish.
