Marble Sort Level 128 presents a two-tiered central barrier that blocks the mid-board. You must clear 24 marbles to lower the first plate and 48 to drop the second, unlocking the core. The opening demands precise side play; mismanaging the belt leads to a jam.
The board has two side columns. On the far left, from top to bottom, are Green, Orange, then Pink. Just inward, you see Light Blue, Purple, and a block of Light Blue at the base. The far right column holds Purple, Brown, then Dark Grey. Inward on the right are Red, Pink, Orange, and a Purple block at the bottom. Two Tunnels with a '3' sit atop the outer columns, but they are decoys. The bottom row of boxes (front line) from left to right: Purple, Light Blue, Purple, Red. Behind them wait Light Blue, Orange, Purple, and Dark Grey boxes.
Marble Sort Level 128 Walkthrough
The immediate demands: the front row needs Purple, Light Blue, and Red. The far-side Green and Brown marbles have no matching front boxes, so they must wait. The central plates will drop only when you clear enough bottom targets, so feed the front row first.
The critical trap: pulling the outer Green or Brown too early consumes belt slots with no destination, causing a backlog once the mid-game chaos begins.
How to Beat Marble Sort Level 128 — Step-by-Step
Phase one: Feed the front line
- Tap the solid Purple cluster at the bottom right of the top tray; guide those marbles into the two front Purple boxes.
- Tap the solid Light Blue cluster at the bottom left; deliver those marbles into the front Light Blue box.
- Pull the exposed Red marbles from the inner right column; send them into the front Red box.
- As boxes cycle, new Light Blue, Orange, and Purple boxes appear. Tap the exposed Light Blue on the left flank; empty them into the new Light Blue box.
- Pull the Orange marbles from the right side, but avoid the adjacent Brown; feed the Orange box.
Phase two: Drop the first plate
- Once the 24-clear threshold is met, the bottom plate shatters, revealing a central T-shape of marbles: Pink, Red, Orange, and Light Blue. Simultaneously, a Dark Grey box and more Orange boxes slide forward.
- Target the newly exposed Orange and Pink in the center; route them into the fresh Orange boxes.
- Combine the Pink from the left flank with the center Pink; fill the Pink boxes that come up.
- Now that the belt has space, tap the left Tunnel; let its contents drop. Match them with active boxes; if an unmatchable color appears, let it sit but avoid tapping the right Tunnel yet.
- Pull the Dark Grey marbles from the far right edge; feed the Dark Grey box.
Phase three: Unlock the core
- After clearing 48, the top plate lifts, exposing the back. Clear the Brown marbles from the top center and right edge; deliver them to the Brown boxes that finally surface.
- Pop the right-side Tunnel and handle its contents immediately.
- Now pull the Green marbles from the far left; send them to the Green box that cycles forward.
- Flush remaining stray colors to finish the board.
Tips & tricks
- Always prioritize feeding the front row over clearing outer colors.
- Keep the belt as empty as possible; avoid pulling a color without a matching box.
- Use the Tunnels only when you have spare belt capacity.
Common mistakes
- Pulling Green or Brown early clogs the belt with no destination.
- Tapping the right Tunnel too soon overloads the belt during the mid-game.
- Ignoring the front row's demands delays the panel drops, causing a backlog.
