Marble Sort Level 337 is a puzzle where the board's layout seems straightforward but hides a tricky sequence. The key is to unlock the lower receivers in a specific order: first Green and White, then Red, Purple, Light Blue, and finally Orange, Yellow, and Brown. Avoid the tempting front clusters and the central Elevator until the path is clear.

The board has a Top Tray with a front row of five clusters: Purple, Green, Light Blue, Green, and Red. The bottom grid initially shows two Green Boxes and two White Boxes on its top layer. On the far left side, a vertical chain of Connected Boxes holds Yellow, White, Light Blue, and Green from top to bottom. The middle of the Top Tray has a four-slot Elevator covered in Mystery Boxes. On the top right, a Blue Tunnel marked with a "3" waits to release extra marbles.

Marble Sort Level 337 Walkthrough

At the start, the bottom receivers are the two Green Boxes and two White Boxes. The two Green clusters in the front row are safe to tap, but the Purple, Light Blue, and Red clusters must wait because their receivers are hidden under the White Boxes. The White marbles are locked in the left-side chain, so you must extract them carefully.

The main trap is the central Elevator: it looks like a target, but touching it early floods the Conveyor Belt with unmatched colors. Also, the Blue Tunnel on the right can dump extra marbles if you trigger it too soon.

How to Beat Marble Sort Level 337 — Step-by-Step

Phase one: Unlock the Green and White receivers

  1. Tap the two front-row Green clusters in the Top Tray to drop them into the two Green Boxes on the bottom.
  2. Ignore the Purple, Light Blue, and Red front clusters for now.
  3. Move to the far-left chain of Connected Boxes. Drop the bottom of that chain (which is Green) to bring the White cluster into play.
  4. Send the White marbles into the two available White Boxes on the bottom board.
  5. After clearing those Green and White Boxes, the next layer of receivers is revealed: Red, Purple, and Light Blue Boxes.
  6. Now tap the front-row Purple, Light Blue, and Red clusters; they now have safe places to land.

Phase two: Survive the Elevator reveal and manage the belt

  1. The four-slot Elevator in the middle of the Top Tray activates after the front row is cleared, revealing four Mystery Boxes.
  2. Pause and check your lower board: you should now have Orange, Purple, and fresh Green Boxes available.
  3. Carefully pull matching colors from the newly revealed Elevator slots, prioritizing Orange and Purple.
  4. Watch the Conveyor Belt: Orange, Blue, and Yellow marbles start flooding the tray as the middle opens up. If you have a single cluster of Blue or Yellow with no receiver, let it sit on the belt but do not drop a second unmatched color.
  5. Address the top-right Blue Tunnel: it holds three clusters. Only drop the box blocking its entrance when you have a cleared lower Box ready to catch whatever spills out.

Phase three: Clear the final connected pairs

  1. Look at the top center of the Top Tray: there is a Red and Brown pair of Connected Boxes.
  2. Hold off on dropping this pair until you have successfully dug down to the Brown receiver on the far left column of the lower grid.
  3. Sweep the remaining Mystery Boxes on the lower board, always targeting those sitting directly on top of other blocked boxes.
  4. Funnel the last of the Yellow and Light Pink marbles into their respective columns to finish the board.

Tips & tricks

  • Always clear the Green and White receivers first; they unlock the rest of the lower grid.
  • Keep the Conveyor Belt clear by avoiding dropping unmatched colors, especially during the Elevator reveal.
  • Use the Blue Tunnel as a last resort; only trigger it when you have a receiver ready for its contents.

Common mistakes

  • Tapping the front-row Purple, Light Blue, or Red clusters early, which clogs the belt because their receivers are still hidden.
  • Activating the Elevator too soon, causing a flood of Orange, Blue, and Yellow marbles with no place to go.
  • Ignoring the left-side chain and failing to extract White marbles, leaving the White receivers unused.
