Marble Sort Level 552 is a puzzle that demands careful planning because of a tricky setup: a T-shaped group of grey mystery blocks sits above, while the lower boxes seem mismatched at first. You must focus on clearing the left side early to create space, then methodically handle the hidden colors as they appear. The key is to never rush—every move should be deliberate to avoid clogging your Conveyor Belt.

The board's top tray has a front row with Orange on the far left, then Green, Dark Blue in the middle, Light Blue, and another Green on the far right. Behind these, a wall of Hidden Boxes holds more marbles, including the crucial Purple and Dark Green. The bottom row of active boxes, from left to right, demands Orange, Pink, Orange, and Purple. A second row behind that will later shift up, requiring Green, Light Blue, Black, and Green. And a third row, which comes into play mid-game, has Connected Boxes: Dark Blue and Dark Green are locked together and must be filled at the same time.

Marble Sort Level 552 Walkthrough

Your immediate targets are the first two boxes on the left: they need Orange and Pink, and you have those stacks conveniently placed on the far left of the top tray. The middle and right side are trickier—the Green stack on the far right is a decoy, because it hides the Purple you need for the far-right box. You'll have to temporarily park that Green on your Conveyor Belt to reach the Purple, but be careful not to let it sit there too long.

The main trap is the Green on the right: it looks like an easy clear, but there's no Green box in the front row. If you tap it too early, you'll waste space and might jam your belt. Instead, use it as a temporary holding spot while you take care of the Purple.

How to Beat Marble Sort Level 552 — Step-by-Step

Phase one: Secure the left side

  1. Tap the Orange stack on the far left, and send all its marbles to the first bottom box, which empties it.
  2. Now tap the Pink stack that was behind the Orange, and drop those into the second box to clear it.
  3. Shift your attention to the far right. Tap the Green stack there and let it sit on your Conveyor Belt—this frees up the Purple behind it.
  4. Tap the Purple stack that is now exposed, and guide it to the far-right bottom box to empty that as well.
  5. You still have an Orange box in the front row (the third one). To find Orange marbles, look to the mid-right area of the top tray, where they are buried behind the Light Blue stack. Carefully move the Light Blue out of the way, but be ready to manage your belt space.

Phase two: Address the midgame rows

  1. Once the first row of boxes is cleared, the next row slides up, showing Green, Light Blue, Black, and Green boxes. The Green you parked earlier will automatically move into the new Green box, so that's one less worry.
  2. Clear the Green stack from the mid-left area and feed it to the remaining Green box.
  3. Now target the Light Blue boxes. You have a Light Blue stack on the mid-left and another on the front-right. Send these down to fill the Light Blue box.
  4. Start breaking the lowest Hidden Boxes in the T-shape. Tap them to reveal their colors, and only drop them if you have at least three empty slots on your belt. Otherwise, hold off until you create space.
  5. As you reveal marbles, prioritize clearing any color that matches an active standalone box. Keep your belt as empty as possible.

Phase three: Break the Connected Boxes

  1. When the third row shifts up, you'll face the Connected Boxes: Dark Blue and Dark Green are bolted together, so both must be filled simultaneously. Start by clearing the Dark Blue stack from the center of the top tray and send it to the left half.
  2. Now hunt for Dark Green. Rapidly clear the remaining Hidden Boxes, looking for Dark Green marbles. When you find some, drop them into the right half.
  3. Continue clearing the Hidden Boxes, matching colors to the active boxes. Keep your belt clear so you can store any mismatched colors temporarily.
  4. Once the Connected Boxes are satisfied, the pressure is off. Clear the rest of the T-shape, match everything else, and finish the level.

Tips & tricks

  • Always count your empty belt slots before tapping a Hidden Box; you need at least three to safely store a new color.
  • Use the Green decoy on the right as a temporary parking spot, but don't leave it there too long—it will be needed later.
  • Clear the left side first because it opens up two boxes and gives you room to maneuver.
  • When the Connected Boxes appear, focus on finding both Dark Blue and Dark Green quickly; don't waste moves on other colors.

Common mistakes

  • Tapping the right-side Green early, thinking it matches a box, but there is no Green box available at that moment—this fills your belt with an unwanted color.
  • Ignoring the need to keep belt space free; if you fill it with random colors, you'll be stuck when you reveal a needed marble.
  • Forgetting that the Connected Boxes require simultaneous filling; if you clear one half but not the other, you'll lose an active slot.
