Marble Sort Level 767 Guide: The Central Lock and Key Trap

Stuck on Marble Sort Level 767? Yeah, this one is a real headache. The board looks like a fortress with that massive Lock and Key system staring you down. The whole puzzle revolves around getting that one Key without burying yourself in useless marbles.

The primary colors you'll be juggling at first are Brown, Pink, and Dark Green, with a ton of Yellow waiting below. The Top Tray is dominated by a giant chain with a Lock, sealing off the entire top row. Below it, you’ve got four strange Multi-Color Dispensers and a critical cluster of three single-color dispensers in the center. The bottom Boxes are stacked four deep in columns, creating a high risk of jamming the Conveyor Belt.

Success in Marble Sort 767 depends entirely on your opening moves. You must ignore the tempting dispensers on the sides and focus on the small group in the middle to find that all-important Key.

The Lock and Key Puzzle in Marble Sort Level 767

This level is designed to trick you. The first thing you see is the giant chain and Lock at the top. This chain blocks five Hidden Boxes, making a huge portion of the board inaccessible. To the right of the central dispensers, you can see a single Key. It’s trapped in a Hidden Box, and getting it is your only priority.

Your only available moves are the three dispensers in the very center: a Pink one, a Dark Green one, and a Red-Brown one. These are your starting tools. The absolute biggest trap on this board are the four fuzzy-looking Multi-Color Dispensers (two vertical, two horizontal). They contain Green, Blue, and Purple marbles. If you touch them before you're ready, you will fail. There are no Blue or Purple Boxes visible at the start, so releasing them will instantly clog your Conveyor Belt and end your run.

The bottom Boxes are the other half of the puzzle. You have four columns of stacked colors. The left column starts with Brown, then Green. The third column also starts with Brown, then Green. The fourth column starts with Yellow, then Brown. This tells you that Brown is an extremely valuable color to clear first. Releasing any other color first is a waste of precious space on the belt. The whole strategy for Marble Sort Level 767 is to use one of the central dispensers to clear a matching Box below, which in turn reveals the Hidden Box containing the Key.

Marble Sort Level 767 Step-by-Step Walkthrough

This level requires a precise sequence. One wrong move at the start and you’ll have to restart. Follow this order to keep the Conveyor Belt clear and break open the board.

Phase 1: Finding the Key

Your first few taps are everything in Marble Sort 767. The goal here is simple: get the Key without adding any junk to the Conveyor Belt.

1. DO NOT TOUCH the four large Multi-Color Dispensers on the sides. They are bait. Releasing the Purple and Blue marbles they contain will cause an immediate jam.
2. Focus only on the three dispensers in the center: Pink, Dark Green, and Brown.
3. Look at the bottom Boxes. The top layer needs Brown Boxes cleared from columns 1 and 3, and a Yellow one from column 4. Brown is the most useful color right now.
4. Tap the central Brown dispenser to release its marbles.
5. Immediately send them into the Brown Box at the top of the first or third column. Clear it.
6. This action will reveal the Hidden Box next to the dispenser you just used. This box contains the Key.
7. A Key Box will appear. Tap it immediately to release the Key. This will finally unlock the chain at the top of the board, giving you access to the five Hidden Boxes up there.

Phase 2: Managing the Multi-Color Dispensers

With the Lock gone, the level opens up, but it also gets more complex. Now those Multi-Color Dispensers you were ignoring come into play.

1. Now that the top is open, you need to start revealing the Hidden Boxes to see what colors are needed.
2. Your next logical clear is the Green Boxes in columns 1 and 3.
3. To do this, you must now use one of the Multi-Color Dispensers. Remember their order: they release Green first, then Blue, then Purple.
4. Tap one of the Multi-Color Dispensers. Send the Green marbles down to clear a Green Box.
5. Brace yourself. A Blue marble is coming next. You must have a plan for it. The Hidden Boxes you are starting to reveal will contain the Blue and Purple Boxes you need.
6. Your new goal is to create a rhythm: reveal a Hidden Box (by clearing the dispenser or Box next to it), identify its color, then release the matching marbles to clear it.
7. Use the single Pink and Green dispensers strategically to clear matching Boxes and reveal more Hidden Boxes around them. This is how you’ll find homes for the Blue and Purple marbles from the big dispensers.

Phase 3: Clearing the Board

The final phase of Marble Sort Level 767 is about careful management. The board is mostly open, but the Conveyor Belt is still your biggest enemy.

1. Focus on clearing one or two columns completely. This creates empty space and makes the remaining moves much easier to see.
2. The stacks of Yellow and Pink Boxes are the main obstacle now. Use the single Pink dispenser and whatever Hidden Boxes turn into Yellow to work through these columns.
3. Never release marbles from a Multi-Color Dispenser unless you have a confirmed plan for at least the first two colors that come out (Green and Blue).
4. Continue revealing and clearing the Hidden Boxes from the top row and the center. They hold the remaining colors you need to finish the level.
5. Keep the flow steady and prioritize clearing any marble that lands on the Conveyor Belt. If you stick to the plan, you'll beat this tough Lock and Key puzzle.
