Marble Sort Level 773 Guide: The Key, the Lock, and the Counter

Stuck on Marble Sort Level 773? Yeah, this one looks like a mess. You’ve got a Lock in the middle of the board, a Key that doesn’t seem to have a matching Box, and two different counters. It’s designed to make you waste moves.

The trick to Marble Sort 773 is knowing what to ignore. The Lock and Key are bait, at least for the first half of the level. Your real mission is to clear four specific Boxes to disable a counter on the left, which gates your progress. Let’s break down how to get it done without jamming the Conveyor Belt.

The Locked Grid in Marble Sort Level 773

First, let's get a handle on this weird layout. The Top Tray is split into two main sections. On the right is a big 4x5 grid of mixed marbles: light blue, pink, yellow, teal, purple, orange, and brown. On the far right, a red dispenser is waiting to cause trouble later.

The left side is where all the mechanics are. At the very top left is a Key Booster, which you likely have active for this level. Below that are single green and dark blue marbles. In the center, a Lock blocks a yellow and a pink marble. To its left sits a crucial counter with a '4' on it, holding an orange marble hostage. Finally, at the top of the third column, a Tunnel promises to release four mystery marbles when you least want it to.

The bottom Boxes are stacked deep, mostly with red, dark blue, light blue, and white. Notice the problem? The Top Tray is full of pinks and yellows blocked by a Lock, but there are no pink or yellow Boxes in sight at the start. That’s the trap. Your goal is to ignore the locked marbles and focus on what you can clear to satisfy that '4' counter.

Marble Sort Level 773 Step-by-Step Walkthrough

This level is all about sequence. Follow this order, and you’ll keep the Conveyor Belt clear and the path open.

First Goal: Pop the '4' Counter

Your only job at the start of Marble Sort 773 is to clear any four Boxes to unlock the orange marble on the left. Do not touch the Key Booster. Do not try to get to the locked marbles. And absolutely do not tap the Tunnel.

1. Target Easy Matches: Start with colors that have a clear path to an open Box. There’s a light blue marble at the top of the grid and a light blue Box accessible in the right-most columns. Send it down.
2. Clear an Orange: Find the orange marble in the fourth column of the main grid. An orange Box is waiting for it in the middle stacks. This is another safe clear.
3. Find a Red Marble: A red Box is waiting on the far left. The easiest red marble to grab is in the bottom right of the main grid. Send it over.
4. Grab a Dark Blue: The second Box from the left needs a dark blue marble. There's one conveniently located on the top row of the main grid. Release it and send it to its Box.
5. Counter Unlocked: Once that fourth Box is cleared, the counter on the left will activate, releasing the orange marble it was holding. Now the mid-game begins.

Mid-Game Strategy: Managing the Board

With the counter gone, you have a bit more freedom, but also more risk. The Conveyor Belt can get crowded fast if you make the wrong choice. The Lock is still a distraction—continue to ignore it for now.

1. Use the New Orange Marble: The first thing you should do is use the orange marble you just unlocked. Send it to the next available orange Box. This keeps the Conveyor Belt clean.
2. Clear the White Boxes: You have two white Boxes in the center columns. The white marbles are a bit buried in the main grid, but they are accessible. Prioritize clearing these to lower the stacks and reveal what’s underneath.
3. Use the Rainbow Dispenser: That colorful creature on the left is your secret weapon. Don't use it randomly. Wait until a useless marble (like purple or teal) is blocking a useful one (like red or dark blue). Use the rainbow marble to complete a set, which gets the useless marble off the board and onto the belt, where you can hopefully manage it.
4. Resist the Tunnel: Seriously, do not touch the Tunnel yet. It will dump four marbles onto the belt and likely cause an instant loss. Wait until you have cleared at least half of the bottom Boxes and have plenty of room.

Finishing Marble Sort Level 773

The end of this level is a race against clutter. Once the stacks are low, you’ll have to deal with the remaining mechanics.

1. When to Use the Key: You've made it this far without the Lock. You may never need it! But if a yellow or pink Box is revealed under the initial stacks, that's your cue. Tap the Key Booster icon to open the Lock. This releases the yellow and pink marbles so you can finally clear those Boxes. If no such Boxes appear, you can use the Key simply to get the yellow and pink marbles out of the way to access other colors behind them.
2. Brace for the Red Dispenser: That red block on the right will eventually start dropping red marbles. Try to clear out as many non-red Boxes as you can before this happens. When the red marbles start coming, make sure you have red Boxes ready.
3. Empty the Tunnel Last: Once the board is mostly clear and you're running out of moves, it's finally time to tap the Tunnel. Make sure the Conveyor Belt is as empty as possible. The four marbles will drop, and you can sort them into the remaining Boxes.

By focusing on the '4' counter first and ignoring the Lock, you bypass the level's main trap. Keep your Conveyor Belt tidy, and Marble Sort 773 is totally beatable. Good luck
