Marble Sort Level 52 — Walkthrough and Solution

Level 52 is the arrow box dependency chain. Arrow Boxes point inward everywhere, so the board solves inside-out — hit the Dark Red first, then the Brown, then the middle Light Green, and chase an arrow chain only once a matching Box is already showing.

Marble Sort Level 52 is a lock puzzle more than a colour puzzle. Nearly every outer column is an Arrow Box that refuses to move until the square it aims at gets emptied, and since most arrows point inward or downward, you must open the centre before the sides. The front row of bottom Boxes wants a huge amount of Dark Red — three separate Boxes — plus one Light Green, with Brown filling the row behind it.

The Top Tray is a 3x5 sheet of Arrow Boxes wrapped around a small open centre pillar, and three extra open boxes hang off the bottom edge. On the far left, a Pink arrow aims down at an Orange arrow, which aims down at a Light Blue arrow aiming right — that whole wall stays frozen until the inner columns are gone.

Marble Sort Level 52 Walkthrough

The trap to dodge is the open Pink box in the bottom-left corner. It looks free, but there is no Pink Box in the front row, and every box here dumps nine marbles while a bottom Box only takes three — so firing it early strands six unusable Pinks on the Conveyor Belt and kills the run.

Treat the opener as a fixed sequence. Dark Red wipes all three of its Boxes in one shot, Brown does the same, and the few stray Light Greens just rest on the belt for a moment. The sides only come alive once the centre has empty room.

How to Beat Marble Sort Level 52 — Step-by-Step

Open the centre

  1. Hit the Dark Red open box on the far right of the three hanging open boxes — its nine marbles fill and clear all three Dark Red Boxes up front.
  2. Second, hit the open Brown box at the bottom middle to drop nine Browns and wipe the three Brown Boxes that just stepped forward.
  3. Now hit the open Light Green box in the middle of the pillar; it feeds the Light Green Boxes and leaves only a couple of strays on the belt.
  4. With room in the centre, the Green arrow pointing right and the Orange arrow pointing left are live — but press one only if its colour has a Box waiting below.

Unwind the right edge

  1. Down in the bottom-right of the main grid sits a Brown arrow aiming left. Once the gap beside it is clear, press it.
  2. That releases the Green arrow above to slide down into the opening.
  3. Clearing that Green arrow then frees the Brown arrow up in the top-right corner.
  4. Before you fire any newly unlocked arrow, confirm its colour is showing in the active front row.

Hold the belt through the midgame

  1. The bottom Boxes now flip through Purple, Light Blue, Orange, and Pink, and the belt tightens because each arrow has to fire before the one behind it can move.
  2. Work the lower-left centre first: the Light Blue arrow aims right at a Purple arrow, so clear the Purple one first.
  3. Moving the Light Blue arrow out of the way is what unlocks the Orange and Pink arrows stacked above it on the left wall.
  4. Keep checking the front row. If Pink is not being asked for yet, hold off and clear Orange and Green first, then resume the chain once Pink shows up.

Tips & tricks

  • Every open box dumps nine marbles, so never fire one unless its three matching Boxes can catch the overflow.
  • The opener is fixed — Dark Red, Brown, then Light Green — and straying from it floods the belt.
  • Peek at the bottom Boxes before extending a chain; unlocked is not the same as needed.

Common mistakes

  • Hitting the bottom-left Pink box early. Nine Pinks with no Pink Box up front clog the belt instantly.
  • Rushing a chain the moment it unlocks. If Pink is not requested, the nine-marble drop has nowhere to land.
