Marble Sort Level 355 — Walkthrough and Solution

Marble Sort Level 355 is a puzzle that rewards patience. The board appears simple at first, but the middle columns hide a trap that can quickly fill your Conveyor Belt. The key is to ignore the center until the sides are clear, then return to finish the job.

The Top Tray has four deep columns. The leftmost column (Column 1) holds, from front to back: Light Green, Green, Pink, Green, Pink, Brown. The rightmost column (Column 4) has: Light Green, Orange, Brown, Purple, Blue, Light Green. The two middle columns start with Green and Yellow, but behind them sit Pink and Blue Arrow Boxes pointing upward, followed by four grey Mystery Boxes, and then Purple Arrow Boxes pointing downward. There are also side pockets: between Columns 1 and 2, a Yellow marble and a Brown Arrow Box pointing right; between Columns 3 and 4, an Orange marble and a Blue Arrow Box pointing left.

The bottom Boxes initially demand, left to right: Light Green, Pink, Light Green, Dark Green. After those are filled, the next set reveals Yellows and Pinks. The front row of the Top Tray matches these demands, but the trap is that the center columns contain Arrow Boxes that cannot be moved until the boxes they point to are gone. Trying to tap them early will send them to the belt as useless cargo.

The one crucial insight: the outer columns are safe to clear first. Only after they are emptied can you approach the center from the sides and safely activate the Arrow Boxes.

How to Beat Marble Sort Level 355 — Step-by-Step

Phase one: Clear the safe front row

1. Tap the Light Green marble at the front of Column 1. It fills the first bottom Box.
2. Tap the Light Green marble at the front of Column 4. It drops into the third bottom Box.
3. Tap the Dark Green marble at the front of the middle-left column. That clears the fourth bottom Box.
4. Tap the Yellow marble at the front of the middle-right column. A Yellow Box is now open, so this marble slides into it.

Phase two: Bypass the arrow trap

1. Do not tap the Pink or Blue Arrow Boxes in the center. They point up at the Mystery Boxes and are locked.
2. Go back to Column 1. Tap the now-exposed Green marble. It goes into a Green bottom Box.
3. Continue on Column 1. Tap the Pink marble, which fits the active Pink Box.
4. Switch to Column 4. Tap the Orange marble. No Orange Box is open yet, but you can park it on the belt.
5. Drop the side-pocket Yellow (on the left) and the side-pocket Orange (on the right) to the belt to clear space.

Phase three: Reveal the mystery and finish

1. After the sides are hollow, the Brown Arrow Box (pointing right) and the Blue Arrow Box (pointing left) become active. Drop them into matching bottom Boxes when they appear.
2. The center blockade breaks. The grey Mystery Boxes reveal their contents: Pink, Blue, and two Purples. Route the Pink and Blue into their boxes immediately.
3. Only the Purple Arrow Boxes and the deep outer colors (Brown, Purple, Light Green) remain. Match the Purples carefully; don't overload the belt.
4. Clear the final Light Green and Brown marbles from the back of the outer columns to finish.

Tips & tricks

• Always clear the outer columns before touching the center arrows.
• Keep an eye on the belt; if it fills, you lose.
• When Mystery Boxes reveal, act quickly to match them.

Common mistakes

• Tapping the center arrows early – they'll clog the belt.
• Dumping multiple Purples at once without an open box.
• Ignoring the side pockets; they are needed for space.
