Marble Sort Level 78 Guide: Beating the Massive 32-Clear Panel Trap

This board is a nightmare of restricted space. You boot it up and immediately see half your playing field completely locked down. The dominant colors in the early game are Cyan, Black, Green, and Red, but you do not have access to most of them.

The single biggest threat here is the massive Panel dominating the entire top left of the Top Tray. It has a giant "32" slapped on it. That means you have to clear exactly 32 bottom Boxes before those top-left marbles even see the light of day. Because of this, you are forced to play the entire early and mid-game using only the center and right side of the board. Space on your Conveyor Belt will be incredibly tight. One wrong pull will end your run early.

The Restricted Right-Side Board Pattern in Marble Sort Level 78

Let’s break down exactly what you are looking at so you do not fall into the early traps. The board is divided into three distinct zones, and two of them are trying to trick you.

On the far left, you have the 32-clear Panel. Ignore it. You cannot do anything about it for the next five minutes. Sitting directly below it in the front row are a Blue marble, a Cyan marble, and a Brown marble.

In the dead center, the board is choked by two Tunnels. They both have a "4" counter on them. You have to drop four marbles from directly underneath them before they open up and release whatever is hiding inside. Right below these Tunnels sit Green, Black, and Pink marbles.

On the top right, things get risky. You have a 3x2 grid of Mystery Boxes marked with question marks. Below them are bright Red and Dark Red marbles.

Now look down at your starting bottom Boxes. The front row dictates everything. From left to right, you need to clear Cyan, Cyan, Black, and Green. The second row of bottom Boxes waiting behind them are Black, Blue, Red, and Blue.

The trap here is obvious. The right side of the Top Tray looks open. It is tempting to tap those Mystery Boxes to see what colors you get. Do not do it. Hitting a Mystery Box when you do not have an open bottom Box to catch that specific color will instantly clog your Conveyor Belt. You have to play front-to-back, strictly answering the demands of the bottom Boxes.

Marble Sort Level 78 Step-by-Step Walkthrough

You are going to play a very tight, controlled game. We have to carve out breathing room before the Conveyor Belt fills up. Follow this exact sequence to break the front line without jamming the board.

Opening the Choke Points in Marble Sort Level 78

Your priority is to clear the Cyan, Black, and Green front-row Boxes using only the exposed marbles in the lower half of the Top Tray.

Clear the Cyan Boxes: You have two Cyan bottom Boxes on the left. Look at the Top Tray. Grab the Cyan marble sitting in the second column. Then grab the Cyan marble sitting in the fourth column. Send them down.
Clear the Black Box: Your middle-right front Box is Black. Pull the Black marble from the third column (right under the left Tunnel). Then, grab the other Black marble sitting just behind where the first Cyan marble was. This clears your first middle lane.
Clear the Green Box: The far-right front Box is Green. Grab the Green marble sitting right in the center of the board.
Manage the Tunnels: By pulling that Black and Green marble, you just dropped the counter on those middle Tunnels from 4 to 3. This is how you slowly chip away at the center blockade. Do not force pulls just to lower the number. Let it happen naturally as you sort.
Ignore the Bait: At this point, do not touch the Mystery Boxes on the right. Leave them alone.

Surviving the Mystery Box Squeeze in Marble Sort Level 78

With the front line gone, the board shifts. Your new target bottom Boxes are Black, Blue, Red, and Blue. The Conveyor Belt pressure is about to skyrocket because the colors you need are buried.

Hunt for Blue and Red: You have exposed Blue marbles on the far left and right center. Pull them to clear those newly revealed Blue bottom Boxes.
Tap the Mystery Boxes Wisely: Now you need Red and Pink. You can see a couple of bright Red marbles on the right, but not enough to clear a Box. This is when you finally tap the bottom row of Mystery Boxes. Tap exactly one. If it drops a Red or Pink marble, send it into the matching bottom Box.
Babysit the Conveyor Belt: If a Mystery Box spits out a Dark Red or Brown marble, leave it on the Conveyor Belt. Do not panic-tap another question mark. Wait until you reveal a bottom Box that matches it. If you let four unmatched marbles pile up on the belt here, you will lose.
Grind the Tunnels Down: Keep pulling matching colors from the center. You will see the Tunnels drop from a 3 count, to a 2, and finally to a 1. When they open, they will reveal more crucial mid-game colors to help you clear the remaining right-side grid.
Push for 32 Clears: Every bottom Box you finish drops the counter on that massive top-left Panel. Keep churning through the Red, Pink, and Black boxes. Stay focused on the right side of the board.

Breaking the Panel and the Final Clean-Up in Marble Sort 78

You have survived the hardest part. You cleared enough bottom Boxes, and the massive 32-clear Panel finally shatters.

Assess the Left Side Drop: When the Panel vanishes, a massive chunk of marbles is suddenly dumped into play. You will see clusters of Green, Brown, and Dark Red.
Match the Backlog: Your Conveyor Belt is probably holding a few random colors from the Mystery Boxes earlier. Look at the new bottom Boxes that just spawned. Immediately prioritize pulling marbles from the newly opened left side to clear out whatever is taking up space on your belt.
Clear the Final Blocks: With the whole board open, the restriction is gone. Pull the remaining Brown and Green clusters from the top left. The right side should be completely empty by now. Send the last few Dark Red marbles down the chute to finish the level.
