Marble Sort Level 338 — Walkthrough and Solution

Marble Sort Level 338 is a puzzle where a locked chain blocks the top half of the board. The key to beating it is to focus all early moves on clearing the center column to unlock the chain, while avoiding the tempting outer marbles that will clog your Conveyor Belt.

The top tray is arranged with a chain across the top rows. Behind the chain sit Orange, Light Blue, Green, Pink, and Purple marbles that you cannot touch. Directly below the lock, in the center column, a Pink marble holds the golden key. This key marble is flanked by a Yellow Arrow Box on the left and a Brown Arrow Box on the right. Below that row, grey Mystery Boxes line the middle, and the bottom playable row of the top tray shows Orange, Yellow, Red, and Pink marbles. The bottom Boxes on the playfield demand Pink (far left), Yellow (mid-left), Light Blue (mid-right), and Brown (far right). The outer edges of the top tray have loose Red and Purple marbles, but these are decoys because their corresponding Boxes are buried deep, so tapping them early will jam your Conveyor Belt.

Marble Sort Level 338 Walkthrough

The front row of the bottom Boxes requires Pink on the left, Yellow next, then Light Blue, and Brown on the right. The immediate goal is to clear Pink and Yellow to open space, then push straight up to the key.

The main trap is the loose Red and Purple marbles on the outer edges of the top tray. They look easy to drop, but their Boxes are hidden behind multiple layers, so if you release them early, they will sit on your Conveyor Belt and cause a jam before you unlock the chain.

How to Beat Marble Sort Level 338 — Step-by-Step

Phase one: Reaching the Key

1. Tap the exposed Yellow marble at the bottom center of the top tray to send it down.
2. Then tap the Pink marble that is also in the bottom center, clearing it to the belt.
3. Ignore the Red on the bottom left and the Purple on the bottom right; do not touch them.
4. Continue tapping Yellow and Pink marbles from the center columns as they become available, aiming to clear the front-left Pink box and the mid-left Yellow box.
5. Once those boxes are cleared, an Orange and a Green box appear in the back row, but your focus stays on the center path.
6. Tap the Orange marble that is blocking the vertical route upward, then the Red marble that sits above it, keeping them on the belt if space allows.
7. Finally, tap the Pink marble that holds the key; the chain will vanish and the upper board opens up.

Phase two: Handling the Arrow Boxes

1. With the chain gone, look to the right side of the bottom Boxes where Brown and Light Blue are waiting.
2. Tap the Light Blue marble that was previously trapped behind the chain, sending it down to clear the front-right Light Blue box.
3. Watch the Arrow Boxes: as you clear the middle, the Yellow and Brown arrows will activate, pushing marbles sideways. Ensure they don't push an unwanted color into a drop spot.
4. Tap the grey Mystery Boxes in the middle rows to reveal their colors; only drop them if they match the current active bottom Boxes (Orange, Brown, or Green).
5. Clear the Brown box on the far right, which will reveal a Yellow box behind it.

Phase three: Clearing the Deep Stack

1. Now focus on the third row of bottom Boxes, which contains Purple and Light Pink.
2. On the left side of the top tray, you'll see a cluster of Purple marbles. Drop exactly three of them to clear the front-left Purple box.
3. Do not drop any more Purples, as that would block the Light Pink marbles you need next.
4. Send down the Light Pink marbles to clear the back-right box.
5. Mop up the remaining Dark Green and Light Green marbles at the top right.
6. Finally, clear the deep Orange and Yellow boxes to finish the level, keeping your taps slow at the end to avoid a last-second belt jam.

Tips & tricks

• Always prioritize clearing the center column until the key is released; the outer colors are a distraction.
• Keep an eye on your Conveyor Belt space; if it's nearly full, hold off on tapping any non-essential marble.
• When Arrow Boxes activate, plan your next move so they push a marble you actually need toward an empty slot.

Common mistakes

• Tapping the loose Red or Purple marbles early, which fills the belt and prevents you from reaching the key.
• Over-tapping Purples in the late game, which blocks the Light Pink marbles needed for a clear.
• Ignoring the Arrow Boxes' direction, causing an unwanted color to drop into a box you haven't prepared.
