Marble Sort Level 615 presents a grid with a top tray and bottom boxes, plus two grey gear blocks stamped with a 3 that block upper rows until enough clears. The board is packed with segmented colors, and the main challenge is avoiding a premature drop of linked blocks that choke the conveyor.

In the top tray, the front row has a Pink, a Yellow, and a Light Blue protruding at the bottom. Behind them, a Dark Blue sits slightly higher. The upper area is guarded by the two gear blocks, behind which are Red, Dark Blue, and Green blocks. The starting bottom boxes, from left to right, demand Dark Blue, Yellow, Purple, and Yellow.

The initial bottom row from left to right is: a Dark Blue box on the far left, then two Yellow boxes in the middle and right, and a Purple box sandwiched between them. These are the only boxes you can fill at the start.

The critical trap is a Light Blue block at the bottom right of the top tray. It is linked to a Light Green block on the far right edge. Tapping the Light Blue early drops both, but neither color is needed in the starting boxes, so it fills the belt with useless marbles and ruins the run.

How to Beat Marble Sort Level 615 — Step-by-Step

Phase one: Front row feeding

  1. Drop the center Yellow block that sits at the front of the top tray, sending it into a front Yellow box.
  2. Release the Dark Blue block on the second row, far left column, to fill the left Dark Blue box.
  3. Leave the Pink block untouched for now because its matching box is buried deeper.
  4. Do not touch the Light Blue block; it is a decoy.
  5. Dig into the middle rows to find Purple blocks and feed the front-center Purple box.

Phase two: Midgame squeeze

  1. As front boxes clear, new boxes shift up, now requiring Red, Green, Light Blue, and Red.
  2. Once a Light Blue box appears on the front line, tap the Light Blue block in the top tray; the linked Light Green will drop and be manageable.
  3. Send Green blocks from the right and middle-left into the new Green box.
  4. After enough clears, the gear blocks pop open, revealing the top row.
  5. Before dropping top-row blocks, ensure the conveyor has at least four empty slots.

Phase three: Cleanup

  1. Drop the two Red blocks from the back-left corner to fill the Red boxes.
  2. Release the Dark Blue cluster from the top center only when a Dark Blue box is fully unblocked.
  3. Finally, tap the remaining Pink blocks to fill the last Pink boxes, keeping a steady pace.

Tips & tricks

  • Always check the conveyor capacity before releasing any block that is not immediately needed.
  • Use the gear blockers as a timer; plan your moves to trigger them when the board is most favorable.
  • If you have extra space, you can park a few unneeded marbles on the belt temporarily, but never let it fill completely.

Common mistakes

  • Tapping Light Blue early, which drops the linked Light Green and floods the belt.
  • Ignoring the gear blockers and trying to access the top row before they open.
  • Dropping top-row blocks when the conveyor is nearly full, causing a jam.
