Marble Sort Level 252 presents a cross-shaped Top Tray with four tunnel exits at the edges and a central column of Arrow Boxes that controls the flow. You must clear Orange, Green, and Red early, but the key is to ignore the side wings until the middle unlocks.
At the start, the middle of the tray holds Orange and Light Blue marbles at the front. Above them, a Green Arrow Box points left and a Red Arrow Box points right. The left wing has Dark Blue and Light Pink, while the right wing has Red, Light Pink, and Purple—these are decoys. The bottom Boxes require Orange, Green, Red, and Orange from left to right.
Marble Sort Level 252 Walkthrough
The lower row of Boxes asks for Orange, Green, Red, and Orange. Hidden beneath these are Light Pink, Light Blue, Purple, and Yellow.
The trap is the central Arrow Boxes: they block the upper layers until you clear the front colors. If you tap the wings too soon, your Conveyor Belt will jam because no matching Box is available.
How to Beat Marble Sort Level 252 — Step-by-Step
Phase one: Unlock the center
- Route the bottom-center Orange marbles into the first and fourth Orange Boxes.
- Park the Light Blue marbles on the Conveyor Belt—no Light Blue Box is active yet, but moving them exposes the Arrow Boxes behind.
- Slide the Green Arrow Box (pointing left) into the second Green Box.
- Feed the Red marbles from the right wing into the third Red Box, but avoid the Purple next to them.
- Deliver the newly exposed Green Arrow Box (also left-pointing) to fill the second Green Box further.
Phase two: Clear the wings
- Drain Light Pink from both wings into the new Light Pink Boxes that appear.
- Release the Dark Blue marbles from the left wing onto the belt—get them out of the way to open the left Tunnel.
- Clear the Red Arrow Box (pointing left) to finish the Red Box.
- Send Purple from the right wing into the Purple Box that has rotated up.
Phase three: Final tunnel rush
- Empty the last Light Blue Arrow Box into the waiting Light Blue Box.
- Remove the top Orange block to open the top right Tunnel.
- When the side Tunnels spill Dark Blue, Purple, and Yellow, only pull them when you have an exact Box match—otherwise you'll jam.
- Match the remaining Yellow and Purple from the bottom queue to finish.
Tips & tricks
- Keep the Conveyor Belt organized—never let it fill with unmatched colors.
- Always clear Arrow Boxes in the order they appear—they gate the upper layers.
- Use the Conveyor Belt as a temporary holding area for Light Blue early, but free it quickly.
Common mistakes
- Tapping Dark Blue or Purple too early—no Box is ready for them.
- Ignoring Arrow Box directions—they only push left or down.
- Dumping tunnel colors before a matching Box is active—instant jam.
