Marble Sort Level 152 — Walkthrough and Solution

Marble Sort Level 152 is a battle against the Conveyor Belt’s limited space, where the board’s opening lineup looks inviting but is actually a decoy. The winning order is Brown, then Red/Green, then the Tunnels, while keeping Orange and Light Blue locked up top until their slots appear.

The top tray presents five front columns: Light Blue, two Browns, then two Oranges. Behind them sit Red (far left), Light Blue (mid-left), a gap, then Red and Green on the right. Higher up, three Tunnels each stamped “3” guard a pyramid of six Hidden Boxes. The bottom receiving area starts with four active Boxes demanding Brown, Red, Brown, Green, backed by a row of Mystery Boxes, and beyond them White, Green, Pink, Light Blue.

Bottom demands run Brown, Red, Brown, Green from left to right, meaning you need six Brown marbles immediately. The front row of the Top Tray conveniently holds two full Brown blocks in the center, which is your only safe opening move.

The trap: Orange and Light Blue blocks sit in plain sight, but no bottom Box asks for them yet. Tapping them prematurely jams the Conveyor Belt, leaving no room for the Tunnel drops that come later.

How to Beat Marble Sort Level 152 — Step-by-Step

Phase one: Clear the front Boxes

1. Release the two Brown blocks from the front-middle of the Top Tray, sending six Brown marbles down to fill both Brown Boxes.
2. Peek at the newly exposed Mystery Boxes in the bottom row.
3. Drop the Red block (located on the right behind the Browns) to feed the Red Box.
4. Drop the Green block that appears next to it, clearing the Green Box.
5. Pause and check the Conveyor Belt; it should be nearly empty now.

Phase two: Expose and fill the Mystery Boxes

1. Read the colors now visible on the Mystery Boxes (expect Orange, Pink, Light Blue, or Red).
2. Now you may safely tap the two Orange blocks on the right side of the Top Tray, guiding them to their matching Box.
3. Slide the front-left Light Blue block down, but only if a Light Blue Box is already open behind the Mystery Boxes.
4. Clear the second layer of the Top Tray: route the far-left Red and the remaining Light Blue blocks into the open slots.
5. Resist touching any block that directly fronts a Tunnel; those counters must stay at “3” until you are ready.

Phase three: Empty the Tunnels and finish

1. Match mid-board colors (Pink, Light Blue, Green) until a Box for White or Dark Blue is exposed and ready.
2. Pull the blocks guarding the Tunnels, dropping each Tunnel’s counter from “3” to “0”.
3. Route the White and Dark Blue marbles that the Tunnels release straight into the waiting Boxes.
4. After the Tunnels are empty, the top Hidden Boxes unlock; use your remaining Conveyor Belt space to sort their revealed colors into the final Boxes.

Tips & tricks

• Keep the Conveyor Belt as empty as possible for the first ten moves; every spare slot is a lifeline when the Tunnels erupt.
• Mentally map which colors are safe to tap: only tap a top block when the matching bottom Box is already uncovered.
• If you must clear a block that feeds a Tunnel, do it right after a Box for its hidden color is revealed—never earlier.
• Use the “3” counters as timers: they tell you exactly how many moves you have before a Tunnel dumps its load, so plan your next three taps accordingly.

Common mistakes

• Treating the Orange and Light Blue front blocks as safe taps—they are bait that fills your Conveyor Belt with no destination.
• Clearing a Tunnel too early, releasing Dark Blue or White before any bottom Box for them exists, which instantly jams the belt.
• Ignoring the order of Mystery Boxes; they hide the true demands, so guessing wrong wastes moves and space.
