Marble Sort Level 55 Walkthrough & Solution
Level 55 Board Overview: A Pyramid with Padlocked Edges

Level 55 throws a visual trick at you the second it loads. The Top Tray is stacked into a steep pyramid, and both outer columns are nothing but Arrow Boxes pointing straight up, each column capped by a Mystery Box. The far-left stack runs Brown, Pink, then Green arrows; the far-right stack runs Light Pink, Light Blue, then Hot Pink arrows.
Here is why that matters: an up-pointing arrow can only fire after the box above it drops. Right now nothing above them has moved, so those edge columns are dead weight. Tapping them just rattles the board.
Your lifeline is the middle three columns. The bottom row of the tray holds a solid Green Box, a solid Brown Box, and a solid Light Pink Box. Two solid Yellow Boxes sit above the Brown and Light Pink, and above those you have an Orange Arrow Box and a White Box. Everything higher is a roof of Mystery Boxes. The front receivers want Brown, Yellow, Yellow, and White, with Yellow, Green, Green, and Brown queued behind them.
The Trap in Marble Sort Level 55
The board is a lesson in playing front-to-back. Each piece of bait:
- The edge columns: six arrows across both flanks, all unclickable until you clear down to them from the inside. They are decoration for now.
- The Light Pink Box: it physically blocks the Yellows you need. It has no receiver yet, so moving it means parking it on your tiny Conveyor Belt.
- The early Greens: the second receiver layer wants Green, but grabbing Green before that layer arrives just clogs the belt.
- The Mystery Box roof: every flip can drop a random color onto a belt with almost no free slots.
The whole solve is hollowing out the center so you can attack the locked flanks from the inside.
Marble Sort Level 55 Step-by-Step Walkthrough
Match the front receiver row exactly and the pyramid opens up.
Opening: crack the center columns

- Tap the solid Brown Box at the bottom-middle of the tray. It drops into the far-left Brown receiver.
- Tap the solid Light Pink Box. It has nowhere to go, so it parks on the Conveyor Belt. That is fine — this hold is the price of reaching the Yellows.
- With Light Pink out of the way, tap both solid Yellow Boxes. They clear the two center Yellow receivers.
- Removing the right Yellow exposes the solid White Box. Tap it into the far-right White receiver.
The entire front row is gone, the lower tray slides forward, and the new demand leans hard on Green and more Yellow.
Mid-game: flank the locked edges
Now it gets spicy. Mystery Boxes are within reach and the edges are still sealed.
- Tap the two solid Green Boxes stacked in the second column from the left. The fresh Green receivers take them both.
- Clearing that column exposes the side of the Mystery Box above the far-left arrows. Tap it — the Green Arrow Box below unlocks.
- In the dead center, the Orange arrow points up at a Mystery Box. Tap the Mystery Box first; once it clears, the Orange Arrow Box activates.
- From here, only drop a Mystery Box color onto the belt if a matching receiver is already waiting — or if you have at least three empty slots to absorb a bad pull.
Cleanup: collapse the peak
With the center gutted, the top of the pyramid caves inward.
- Repeat the flank on the right: clear the Mystery Box sitting above the Hot Pink Arrow Box to unlock the whole right edge.
- As the receivers shift to Hot Pink and Light Pink, fire the freshly unlocked edge arrows into them.
- The last Mystery Boxes at the peak drop down. Your belt should be nearly empty by now, so tap them through to fill the final receivers and finish the board.

Level 55 Tips Recap
- Up-pointing arrows are locked until the box above them drops — the edges are untouchable early.
- Parking Light Pink on the belt is not a mistake; it is the only road to the Yellows.
- Clear the Mystery Box above an arrow before you count on that arrow firing.
