Marble Sort Level 37 Walkthrough & Solution
Level 37 Board Overview: The Locked Top and the Dark Blue Bait

Level 37 greets you with bright, tappable colors and almost nowhere to send them. The palette you are wrestling with is Bright Green, Light Green, Dark Blue, and Pink, plus a wall of gray question-mark blocks holding prime positions. The signature mechanic here is a pair of Panels stamped with a ‘3’ that seal the tops of columns one and three — until you clear three receiver Boxes, that whole upper region stays locked.
The Top Tray has four columns with very different personalities. Column one stacks Orange over two Light Green blocks with a Bright Green at the base. Column two is pure Mystery Box all the way down to a Bright Green base. Column three is a tall Pink tower standing on a single Dark Blue. Column four repeats column two’s trick: Mystery Boxes piled above a Dark Blue base.
Down at the receivers, the front row only gives you two real targets — a Light Green Box and a Bright Green Box in the middle slots. Both outer slots are face-down Mystery Boxes, and a Dark Blue Box is trapped one row behind the Light Green one.
The Trap in Marble Sort Level 37
Every column is wired to punish greedy taps:
- Column one: Orange on top is useless early, but the Bright Green at the bottom is your opening move. The two Light Greens in between are your second clear.
- Column two: a blind stack. The only thing you know for sure is the Bright Green base, which pairs with column one’s base to fill the Bright Green Box.
- Column three: the Pink tower looks juicy, but its foundation is a Dark Blue block — and Dark Blue is the most dangerous color on the board right now.
- Column four: same story as column two, except the base is the second Dark Blue.
Here is the bait: Dark Blue sits exposed at the bottom of two columns, practically asking to be tapped. But the Dark Blue Box is stuck in the second row of receivers. Drop those blocks now and they camp on your Conveyor Belt with nowhere to go, choking the exact space you need for the Mystery Box reveals later. The level is counting on you to grab the obvious match before the board is ready for it.
Marble Sort Level 37 Step-by-Step Walkthrough
The first six taps are scripted. Follow them in order.
Opening: burn down the two green Boxes

- Tap the Bright Green block at the base of column one.
- Tap the Bright Green block at the base of column two. Together they fill the Bright Green receiver Box — first clear, and the Panels tick from 3 down to 2.
- Tap both Light Green blocks in column one, now uncovered.
- They drop into the Light Green Box for your second clear — Panels read 1. Watch the bottom area: the Dark Blue Box slides forward into the active row the moment Light Green clears.
Mid-game: Dark Blue clears and the Panels retract
- Tap the Dark Blue block at the base of column three.
- Tap the Dark Blue block at the base of column four. That finishes the Dark Blue Box — your third clear. Both Panels vanish and the sealed tops of columns one and three open up.
- Now work the Mystery Boxes in columns two and four. Tap two or three, pause, and check which receiver Boxes are asking for what before you tap more. Never mass-tap the gray stack.
Cleanup: empty the Pink tower
The board is fully unlocked and the belt has breathing room again.
- Dump the entire Pink stack from column three — a Pink Box will be waiting by now.
- Drop the Orange block from the top of column one as soon as an Orange Box reveals itself in the receivers.
- Finish the remaining Mystery Box reveals one match at a time, letting the front row of Boxes choose your next tap.

Level 37 Tips Recap
- The front-row Boxes write your opening script: Bright Green, Light Green, Dark Blue, in that order.
- Three clears retract the Panels — know which three before you tap anything.
- Treat Mystery Boxes like a slow drip, not a faucet. Two or three at a time, then reassess the belt.
