Marble Sort Level 6 is the first real gut-check in the game, and it beats you with a stack of Purple you can't reach. Three of the four active Boxes want Purple, yet there isn't a single Purple cluster in tapping range — it's locked behind Orange and a wall of question marks. The whole level turns on one ugly rule: dump the Orange on purpose, because that's the only way to dig the Purple out.
Read the board left to right and it tells you everything. The active Boxes run Purple, Purple, Purple, and a lone Yellow on the far right. Underneath sit Orange (columns one and two), Green (column three), and a Yellow-over-Purple stack in column four. Up top, the tray serves a front row of Green, Orange, Yellow, Yellow — and not one Purple among them.
Marble Sort Level 6 Walkthrough
Your only visible Purple hides in the middle row, pinned behind the front Orange. Wrapped around it is a U of grey Mystery Boxes you can't read until you carve a path up the centre. That Green on the far left is dead weight: no Green Box is open, so tapping it just parks marbles on the belt. Your safe side is the right; your choke point is the middle.
How to Beat Marble Sort Level 6 — Step-by-Step
Survive the opening blockade
- Tap both Yellow clusters on the right side of the tray. They roll down and knock out the Yellow Box in column four.
- That clear raises a Purple Box in column four, so now every active Box wants Purple.
- You can't reach the Purple without moving the front Orange, so tap the Orange cluster and let it loop on the belt. That's a required sacrifice, not a mistake.
- With the Orange gone, tap the newly exposed Purple cluster. It drops and clears a Purple Box, usually in column one or two.
- Clearing that Purple surfaces the hidden Orange Box. The Orange you parked on the belt flies straight into it, and the belt is clean again.
Crack the Mystery wall
- The first big clear strips the front line and flips the Mystery Boxes, mostly revealing more Purple and Orange, with the odd Yellow.
- Now watch the left side. Your original Green cluster is still untouched. Column three's Green Box was buried under Purple — once that Purple clears, the Green Box goes active, and that's your moment to tap the front Green.
- The belt gets tight here because the entire back row is Mystery Boxes. Clear Purple first, and match every newly revealed colour to a secondary Box right away.
Clean the last layers
- Don't strand a colour by clearing the wrong Box too fast. Check how deep each stack goes before you pull.
- If two Yellow Boxes sit deep in column four, hold your Yellows until both are fully raised.
- Keep matching from the inside out, avoid blind guesses on remaining Mystery Boxes unless you have two free belt slots, and the last sequence clears itself.
Tips & tricks
- The right side is your only safe opener — clear those two Yellows before touching anything else.
- The front Orange isn't a target, it's a key. Park it on the belt and let the follow-up clear rescue it.
- Read Box depth before each endgame tap; column four stacks two Yellows deep.
Common mistakes
- Tapping the far-left Green early. No Green Box is active, so it loops and wastes a slot.
- Panic-clearing Mystery Boxes late. A wrong reveal on a full belt is a dead run.
Marble Sort Level 6 FAQ
Why does my Conveyor Belt flood on Marble Sort Level 6?
You tapped the far-left Green cluster before any Green Box was active, so nine marbles looped on the belt. Clear the two right-side Yellows first, then sacrifice the front Orange to reach the Purple.
Which color do I clear first on Marble Sort Level 6?
Yellow, on the right side. Those two clusters clear the column-four Yellow Box, which raises the first Purple Box and opens the board to the Orange sacrifice.
How many moves does it take to clear Marble Sort Level 6?
Roughly ten taps across three phases — the two Yellows, the Orange sacrifice and Purple clear, then the Mystery-wall clears and the inside-out endgame.
Do I need boosters to beat Marble Sort Level 6?
No. Dump the front Orange on purpose to reach the Purple and the board cascades open. Save boosters for boards with locks and hidden Boxes.
What happens if I tap the far-left Green first?
It sits on the belt with no Green Box to catch it, eats a slot, and stalls the Purple clears you actually need. One early grab can choke the run.
