Marble Sort Level 772 is a Lock and Key puzzle with Numbered Panels, and it throws a chaotic opening at you. The bottom Boxes demand Green, Yellow, Pink, Blue, and Light Blue, while the Top Tray mixes many colors behind barriers. You must handle the initial marble dump, then unlock the board in a set order to win.

At the bottom of the Top Tray sit three large clusters: two Yellow and one Light Blue. These spill many marbles at once onto a short Conveyor Belt. The Yellow Box is second from the left, the Light Blue Box far right. The center columns are blocked by a Numbered 2 Panel on the left and a 3 Panel on the right, which vanish only after you clear that many Boxes. A Lock guards the bottom of the Blue Box column, and six Keys rest in the tray: two Pink, one Cyan, one Red, one Blue, one Green. The sparkling Blue Key on the far-right nub is the one you need.

The bottom Boxes, left to right: Green, Yellow, Pink, Blue, Light Blue. Clearing a Box removes it and moves you toward opening the Panels. The trap is touching side marbles or Keys before you deal with the clusters, because that jams the belt.

The specific imbalance: the initial flood from the Yellow and Light Blue clusters can fill the Conveyor Belt instantly, making it impossible to sort anything. You must prioritize those two colors to survive.

How to Beat Marble Sort Level 772 — Step-by-Step

Phase one: Control the flood

  1. Tap the two Yellow clusters and the one Light Blue cluster at the bottom of the Top Tray.
  2. Route all Yellow marbles into the second Box from the left, clearing it.
  3. Guide all Light Blue marbles into the far-right Box, clearing it as well.

Phase two: Open the Panels and the Lock

  1. Clear one more Box to remove the 3 Panel; the far-left Green Box is the best target.
  2. Release Green marbles from the top and left side of the tray and deliver them to the Green Box.
  3. With the 2 Panel gone and the central area open, locate the sparkling Blue Key on the far-right nub.
  4. Drop the Blue Key into the Blue Box column, fourth from the left, to break the Lock.
  5. Clear the Blue marbles from the newly accessible central area into the Blue Box.

Phase three: Sort the rest

  1. Focus on one color at a time; clear the Pink Boxes, which also removes the two Pink Keys.
  2. Release remaining marbles in small batches to keep the Conveyor Belt manageable.
  3. Work through the remaining stacks, matching each color to its Box until all are cleared.

Tips & tricks

  • Always clear the Yellow and Light Blue clusters first; they cause the only real jam risk.
  • Use the Green Box early to trigger the 3 Panel removal, as it's accessible from the top.
  • Drop the Blue Key as soon as the central area opens; it unlocks the Blue column for good.

Common mistakes

  • Tapping side marbles or Keys before clearing the clusters, which floods the belt and stalls the level.
  • Ignoring the Green Box and trying to clear a different third Box, which delays panel removal.
  • Releasing too many marbles at once in the final phase, causing a belt jam that forces a restart.
