Marble Sort Level 55 — Walkthrough and Solution

Marble Sort Level 55 hits you with a visual trick the moment you load in. You face a towering pyramid of marbles where Brown, Yellow, and Green lead the way, but both outer edges are sealed by Arrow Boxes that aim straight up. The front row of bottom Boxes wants Brown, Yellow, Yellow, and White.

An Arrow Box only activates after the square it points to has been dropped, and since the bottom-edge arrows point up, they are pure dead weight — they block the bottom but cannot be clicked until the boxes above them clear. The fix is to ignore the edges and hollow out the centre columns, then attack the outer walls from the inside.

Marble Sort Level 55 Walkthrough

The far-left column is a trap: a Brown arrow, a Pink arrow, and a Green arrow all pointing up, capped by a Mystery Box. The far-right column is the same bait, holding Light Pink, Light Blue, and Hot Pink arrows. Do not touch either side — clicking them rattles the board and does nothing.

Your lifeline is the three centre columns. The bottom row holds a solid Green, a solid Brown, and a solid Light Pink, with two solid Yellows above the Brown and Light Pink, and an Orange arrow plus a White box above those. Behind the front row, the second layer wants Yellow, Green, Green, and Brown.

How to Beat Marble Sort Level 55 — Step-by-Step

Crack the centre columns

1. Hit the solid Brown in the bottom-middle to clear the far-left Brown Box.
2. Stage the Light Pink by hitting it — it drops and rests on the belt as a necessary hold.
3. With the Light Pink out of the way, hit both solid Yellows to clear the two centre Boxes.
4. Removing the right-side Yellow exposes a solid White, so hit it into the far-right Box.
5. Watch the shift — the first row is gone and the lower tray now wants Green and more Yellow.

Flank the Arrow Boxes

1. Look at the second column from the left — two solid Greens are stacked, so hit both into the newly shifted Green Boxes.
2. Hit the Mystery Box above the far-left arrows to unlock the Green arrow beneath it.
3. In the dead centre, hit the Mystery Box above the Orange arrow first, then activate the Orange arrow once that clears.
4. Only drop a mystery colour to the belt if a matching Box is waiting, or if you have three empty slots to absorb a bad pull.

Clean the Mystery peak

1. Repeat the flank on the right column by clearing the Mystery Box above the Hot Pink arrow, which unlocks the whole right edge.
2. Drop the Hot Pink and Light Pink arrows now that the bottom Boxes ask for those colours.
3. The last few Mystery Boxes at the top drop down, and with the belt mostly empty you can tap them to fill the final Boxes and finish.

Tips & tricks

• The outer arrow columns are dead weight until the boxes above them clear, so never click them early.
• Stage the Light Pink on the belt on purpose — it is the cheapest way to reach the two Yellows behind it.
• Always clear the Mystery Box above an arrow before tapping the arrow itself, or it stays locked.

Common mistakes

• Clicking the outer arrow columns. They point up and cannot activate, so the taps do nothing while the board stays locked.
• Pulling a mystery colour with a full belt. You cannot see what it is until it drops, so a bad reveal jams the run.
