Marble Sort Level 246 is a punishing puzzle that looks like a minefield of grey Mystery Boxes, but the real danger is the hidden double Mystery Box column that can stall your entire left side. The winning order is to clear the Yellow and Blue gatekeepers at the bottom first, then methodically test the top Mystery Boxes one at a time while keeping your Conveyor Belt nearly empty.

The board has four bottom columns. Column one: Yellow in front, then Red, Blue, White. Column two: Blue in front, then Purple, Red, a Mystery Box. Column three: Yellow in front, then two Mystery Boxes stacked, then another Yellow. Column four: Blue in front, then a Mystery Box, Yellow, Red. Up top, the bottom edge shows Purple, White, Blue, and Yellow clusters, with a central block of Orange, Blue, Red. The rest is a horseshoe of Mystery Boxes.

The front-row Boxes demand Yellow and Blue in that order. The leftmost column wants Yellow, the second wants Blue, the third wants Yellow, and the fourth wants Blue. You must feed those first.

The trap is that Purple and White clusters look ready to drop, but no bottom Boxes can catch them yet, so they'd just clog your belt. The real enemy is the double Mystery Box in column three that hides a second Yellow—if you break it too early, you'll have no place to put it.

How to Beat Marble Sort Level 246 — Step-by-Step

Phase one: Clear the front gates

  1. Send the bottom-right Yellow cluster down to feed the front Yellow Box in column three.
  2. Route the bottom-middle Blue cluster to the front Blue Box in column four.
  3. Drop the visible Blue and Red marbles from the center to finish the front-row Yellow and Blue Boxes.
  4. Leave the Purple and White clusters untouched; they're decoys.
  5. Once the front Blue Box in column two is gone, the Purple Box behind it slides forward.

Phase two: Survive the midgame shift

  1. Clear the Purple Box in column two, then finally release the starting Purple cluster from the top.
  2. Tap exactly one top Mystery Box. If it reveals Green or Light Blue, pause and check for a matching bottom Box.
  3. If a bottom Mystery Box turns into Pink or Brown, immediately find and drop those colors from the center.
  4. Keep at least three empty slots on the belt; never let it fill past two.

Phase three: Break the final wall

  1. As columns three and four expose their deep Boxes, use them to absorb the stranded Green, Light Blue, and White marbles.
  2. Once the belt is clear, rapidly fire the remaining top Mystery Boxes, matching colors quickly before the belt jams again.

Tips & tricks

  • Always prioritize clearing a bottom Box before dropping a new color from the top.
  • If a Mystery Box reveals a color you can't place, stop tapping Mystery Boxes entirely.
  • Use the central Orange and Red clusters to trigger clears when the belt gets tight.

Common mistakes

  • Dropping the Purple cluster too early, which chokes the belt.
  • Blindly tapping top Mystery Boxes without checking bottom Boxes.
  • Letting the belt fill past two empty slots, leaving no room for necessary drops.

Clear Yellow first, then Blue, because those are the front-row Box colors that gate the rest of the board.
