Marble Sort Level 767 — Walkthrough and Solution

Marble Sort Level 767 is a Lock-and-Key puzzle where the entire upper area is sealed behind a chain, and you must locate a single Key to open it. The answer lies in the central cluster of single-color dispensers: Brown, Pink, and Dark Green. Your first moves must exclusively use these three, and you must ignore the four fuzzy Multi-Color Dispensers on the sides until the Lock is broken. The moment you release any Blue or Purple marble prematurely, the Conveyor Belt will choke and you will lose.

The board is arranged with a massive chain and Lock at the top, blocking five Hidden Boxes. Below that, four Multi-Color Dispensers sit in a 2x2 grid (two vertical, two horizontal) and contain Green, Blue, and Purple marbles. In the very center are three single-color dispensers: Pink, Dark Green, and a Red-Brown one. The bottom area is a set of four columns, each stacked four marbles deep. The leftmost column (column 1) starts with Brown on top, then Green below. Column 2 has a different start, but column 3 mirrors column 1 with Brown then Green. Column 4 begins with Yellow, followed by Brown. Brown is the key color to clear first, as it appears in both column 1 and column 3, and clearing it will reveal a Hidden Box containing the Key.

The bottom Boxes demand your attention in a specific order. From left to right, the top layer of each column shows: column 1 has a Brown Box, column 2 has a Pink Box, column 3 has a Brown Box, and column 4 has a Yellow Box. The critical insight is that Brown appears in columns 1 and 3, making it the most efficient color to clear first. You have exactly three safe dispensers at the start: Pink, Dark Green, and Brown. Any other dispenser will release Blue or Purple, for which no matching Boxes are visible, causing an immediate jam.

The board’s trap is the Multi-Color Dispensers. They look tempting, but they contain a sequence of Green, Blue, and Purple. Since no Blue or Purple Boxes are initially visible, using them before the Lock is removed will fill the belt with useless marbles. The only way to win is to use the central Brown dispenser to clear a Brown Box, which reveals the Key. Once the Key is obtained, the top row unlocks, and you can then safely use the Multi-Color Dispensers, as the Hidden Boxes they reveal will provide homes for the Blue and Purple marbles.

How to Beat Marble Sort Level 767 — Step-by-Step

Phase one: Secure the Key

1. Tap the central Brown dispenser to release its marbles.
2. Route the Brown marbles into the Brown Box at the top of column 1 (or column 3, whichever is easier to access). Clear it.
3. Immediately, a Hidden Box appears next to the dispenser you used. Slide its contents to reveal the Key.
4. Tap the Key Box to collect the Key, which will unlock the chain at the top and open five Hidden Boxes.

Phase two: Unlock the Hidden Boxes

1. Now that the top is open, examine the Hidden Boxes to see which colors are needed. You’ll find Green Boxes in columns 1 and 3, waiting to be cleared.
2. Tap one of the Multi-Color Dispensers. It will release Green first. Feed these Green marbles into a Green Box to clear it.
3. Prepare for the next marble: Blue. Look for a Blue Box in the Hidden Boxes you’ve revealed. If none is visible yet, clear another single-color dispenser (Pink or Dark Green) to reveal more Hidden Boxes until you find a Blue Box.
4. Continue this rhythm: clear a Box, reveal a Hidden Box, match its color, and clear it. Use the Pink and Dark Green dispensers to eliminate matching Boxes and expose more Hidden Boxes, which will contain the Blue and Purple Boxes you need.

Phase three: Finish the board

1. Focus on clearing entire columns to create empty space. Start with column 1 or 3, as they have Brown and Green layers that are now gone.
2. Work through the Yellow and Pink Boxes in columns 2 and 4. Use the single Pink dispenser to clear Pink Boxes, and find Yellow Boxes in the Hidden Boxes to clear the Yellow stacks.
3. When using a Multi-Color Dispenser, always have a plan for the first two colors (Green and Blue) before you tap it. Never release a marble without knowing its destination.
4. Keep the Conveyor Belt clear by immediately routing any released marble into a matching Box. If a marble sits too long on the belt, it will jam the system.
5. Continue revealing and clearing all Hidden Boxes until the board is empty. Stick to the order: clear Brown first, then Green, then Blue and Purple, and finally Yellow and Pink.

Tips & tricks

• Always clear Brown first; it appears twice at the bottom, so it’s the fastest way to reveal the Key.
• When a Multi-Color Dispenser releases a Blue marble, have a Blue Box ready by clearing a single-color dispenser to reveal it.
• Use the top Hidden Boxes to your advantage; they often contain the exact colors you need to match the Multi-Color Dispensers.

Common mistakes

• Touching a Multi-Color Dispenser before the Lock is broken, which releases Blue and Purple with no Boxes to receive them.
• Releasing a marble from a Multi-Color Dispenser without a plan for its second color, causing a jam on the belt.
• Ignoring the central Brown dispenser and trying to clear other colors first, which wastes space and delays the Key.
