Marble Sort Level 37 hands you a board full of bright colour and almost nowhere to put it. A pair of Panels seals the upper rows and will not budge until three targets clear. The palette is Dark Blue, Bright Green, Light Green, and Pink, and a wall of grey question-mark blocks claims a fat slice of the tray.
The Top Tray is four columns. Column one carries an Orange perched on a pair of Light Greens, resting on a Bright Green at the base. Column two is Mystery Boxes all the way down to one Bright Green. Column three is a deep Pink stack sitting on a single Dark Blue. Column four copies column two, with Mystery Boxes stacked above a Dark Blue. Two Panels marked 3 hover over the top of columns one and three.
Marble Sort Level 37 Walkthrough
The lower half is full of hidden information. The front row offers just two playable colours — a Light Green Box in slot two and a Bright Green Box in slot three — while both outer slots are grey Mystery Boxes. Behind the Light Green sits a Dark Blue Box, and behind the Bright Green sits another Mystery Box.
The snare is the Dark Blue at the base of columns three and four. It looks like an easy tap, but there is no Dark Blue Box in the front row. Dropping it early clogs the belt and ends the run, so the opening has to squeeze three clears out of nothing but the greens.
How to Beat Marble Sort Level 37 — Step-by-Step
Break the front line
- Tap the Bright Green at the base of column one, then the one at the base of column two, into the Bright Green Box in slot three for your first clear.
- Watch the Panels fall from 3 to 2.
- With the Bright Green gone from column one, the two Light Greens are exposed — tap both into the Light Green Box in slot two for the second clear.
- The Panels now read 1, and the Dark Blue Box that was stuck in row two has moved up to the front row.
Survive the Mystery Box midgame
You now have a home for the Dark Blue, but the risk of clogging the belt spikes.
- Tap the Dark Blue at the base of column three, then the one at the base of column four, into the newly exposed Dark Blue Box for the third clear.
- The Panels unlock and vanish, and column three collapses into a lone giant Pink stack while the Mystery Boxes of columns two and four sit fully open.
- Start tapping those Mystery Boxes carefully — as they fall they reveal a colour or act as grey marbles for the grey Mystery Boxes below.
- Watch your belt capacity and never spam the hidden blocks. Release a couple at a time, check what they match below, then let them sort.
Finish the run
- Dump the entire Pink stack from column three — a Pink Box is ready for it below.
- The Orange perched at the crown of column one is now loose, so drop it into whatever Orange Box has shown up.
- Stay patient with the remaining Mystery Boxes and let the bottom row steer every tap, clearing the last hidden blocks front to back.
Tips & tricks
- Only the greens are safe in the opening. The Dark Blue at the base of columns three and four has no Box until your second clear shifts the board.
- Treat the Panels as a three-clear timer — Bright Green, Light Green, then Dark Blue gets them to zero in order.
- Drop Mystery Boxes two or three at a time so a bad reveal never fills the belt in one go.
Common mistakes
- Dropping Dark Blue in the opening. Its Box is trapped in row two, so the marble loops and stalls the whole run before the Panels tick down.
- Spamming the Mystery Boxes once the Panels vanish. An unexpected colour has nowhere to land and chokes the belt instantly.
Marble Sort Level 37 FAQ
Why does my Conveyor Belt flood on Marble Sort Level 37?
You dropped the Dark Blue at the bottom of columns three or four before its Box slid into the front row. It has nowhere to land, so it loops and stalls the whole opening.
Which color do I clear first on Marble Sort Level 37?
Bright Green, from columns one and two, into the Bright Green Box in slot three. It is the first of the three clears that finally unlock the Panels.
How many moves does it take to clear Marble Sort Level 37?
Roughly a dozen taps across three phases — the two green clears, the Dark Blue third clear, then the Pink and Mystery finish. Stick to the order and the Panels open on schedule.
Do I need boosters to beat Marble Sort Level 37?
No. Clear Bright Green, then Light Green, then Dark Blue and the Panels unlock themselves. Save boosters for the grey Mystery Boxes if they reveal badly.
What happens if I drop Dark Blue too early on Marble Sort Level 37?
It lands on the belt with no Dark Blue Box in the front row, so it loops and eats a slot you need for the greens, ending the run before the Panels reach zero.
