Marble Sort Level 388 — Walkthrough and Solution

Marble Sort Level 388 challenges you to manage a board with a large wooden Crate in the middle of the Top Tray, splitting the play area and forcing careful sequencing. The key is to clear the lower Boxes in a strict left-to-right pattern, then unlock the Crate to access the upper marbles and Tunnels.

The bottom has four columns of Boxes. From left to right, the active demands start as: Dark Green, Yellow, Yellow, Purple. Under these, the queues contain: far-left has Yellow, Brown, then Purple; mid-left has another Yellow, Purple, then Light Blue; mid-right has Brown and two Dark Greens; far-right has Purple and two Yellows. The Top Tray holds clusters: bottom-left Yellow, bottom-right Dark Green, above them Light Blue and Dark Green/Yellow, and a large Crate in the center, flanked by Purple Connected Boxes below. The sides have traps: left has Light Blue tied to Brown, and Light Green tied to Pink; right has Pink tied to Blue, and Light Green tied to Pink. At the top, a row of Pink, Purple, Orange, Pink, Dark Green, Light Green blocks four Tunnels numbered 2, 3, 3, 2.

Marble Sort Level 388 Walkthrough

Your front-row Boxes start with Dark Green on the far left, then two Yellows in the middle, and Purple on the far right. The opening sequence is rigid: you must feed these in a specific order without jamming the Conveyor Belt.

The main trap is the central Crate, which only opens after you clear three adjacent clusters. Pulling the wrong side cluster early, like the Light Blue-Brown pair, will clog the belt because no Light Blue Box is active yet.

How to Beat Marble Sort Level 388 — Step-by-Step

Phase one: Clear the Frontline

1. Tap the large Yellow cluster located at the bottom left of the Top Tray, sending it into the two active Yellow Boxes in the middle columns.
2. Tap the Dark Green cluster on the bottom right, which slides into the Dark Green Box on the far left.
3. After the columns shift, new active Boxes appear: Yellow (far left), Yellow (mid-left), Brown (mid-right), Purple (far-right).
4. Tap the newly exposed Yellow cluster on the lower right of the Top Tray to feed the new Yellow Boxes.

Phase two: Crack the Crate

1. Tap the two Purple Connected Boxes under the Crate, which drop together to fill the active Purple Box on the far right.
2. Do not touch the Light Blue-Brown pair on the left yet, as there is no active Light Blue Box to receive them.
3. Clear the Dark Green cluster on the right side to satisfy the queued Dark Green Boxes.
4. Once enough clusters are cleared, the Crate shatters, revealing the hidden Pink and Blue clusters in the middle.

Phase three: Empty the Tunnels

1. When the mid-left Light Blue Box becomes active, release the Light Blue-Brown pair on the left.
2. Release the Light Green-Pink pairs on both outer edges to clear the side queues.
3. Pull the top row marbles: Purple, Orange, and Pink, feeding the final Boxes.
4. Keep the Conveyor Belt empty before pulling the last top-row marble, then quickly match the tunnel drops (2, 3, 3, 2) to the remaining Boxes.

Tips & tricks

• Always watch the bottom Boxes: only pull a color when its Box is active or about to cycle.
• Prioritize clearing the central Crate early to open the board.
• Leave the side Connected Boxes until their matching colors are active.

Common mistakes

• Dropping the Light Blue-Brown pair too early jams the belt.
• Pulling top-row marbles before clearing side clusters can cause a flood.
• Ignoring the queue order can force you to wait with no matching Box.
