Marble Sort Level 684 Guide: The Dual 23-Panel Trap
Stuck on Marble Sort Level 684? I get it. This board is a masterclass in bait. You load in and immediately face a massive wall. The top of the board is entirely locked down by two giant Panels, each demanding a brutal 23 clears before they open.
You do not get to see the main puzzle right away. Instead, the game forces you to survive on scraps. Your Top Tray gives you a single row of visible marbles and a blind row of question marks. Make one wrong move with your limited visible colors, and your Conveyor Belt will permanently jam before you even scratch the surface of those Panels.
Here is exactly how to break this board down, manage the blind drops, and clear the 23-count trap.
The Brutal 23-Panel Pattern in Marble Sort Level 684
This board layout is designed to force you into a corner immediately. You need to know exactly where the active colors are sitting.
Look at your lower Boxes. The starting row across the four columns is heavily stacked with Red. You have a Red Box on the far left, a Yellow Box in the mid-left, a Red Box in the mid-right, and another Red Box on the far right. That is three Reds and one Yellow demanding your attention right now.
Now look at your Top Tray. The only fully visible marbles are sitting at the very bottom edge. Reading left to right, you have: Purple, Green, Red, White, Yellow, Blue, and White.
Do you see the trap? You desperately need Red marbles to clear those three active Red Boxes. But the visible row only gives you a single Red cluster. You also need Yellow, and you only get one Yellow cluster. The Purple, Green, Blue, and White marbles sitting in plain sight are absolute bait. If you drop them onto the Conveyor Belt now, they will sit there taking up precious space because their corresponding Boxes are buried deep in the lower columns.
To survive Marble Sort 684, your entire early game relies on the horizontal row of Mystery Box tiles sitting directly underneath the massive 23-count Panels. You have to dig blindly into that question mark row to find the missing Reds and Yellows, ticking down the 23 counter one agonizing clear at a time.

Do not touch the outer edges of the visible bottom row yet. We need surgical precision to keep the Conveyor Belt empty.
Surviving the First Drops in Marble Sort Level 684
Your first moves dictate whether you live or die on this board. We have to feed the Red and Yellow Boxes while ignoring the shiny bait sitting in the corners.
- Drop the visible Red: Tap the single Red marble cluster sitting in the third slot of the visible Top Tray row. Send it to the Conveyor Belt. It will drop into one of your three active Red Boxes.
- Drop the visible Yellow: Tap the single Yellow cluster sitting in the fifth slot. This feeds your active Yellow Box in the second column.
- Ignore the bait: Leave the Purple, Green, Blue, and White marbles exactly where they are. Do not pull them down.
- Tap the Mystery Box row: Start tapping the question mark tiles directly above the empty slots you just created. You are fishing for more Red and Yellow marbles.
- Clear the front line: As you uncover Reds from the Mystery Box row, funnel them down. Clearing those first three Red Boxes and the first Yellow Box will finally shift the bottom columns up, revealing Blue, White, and Green Boxes.
- Use the visible leftovers: Once the bottom Blue and White Boxes slide into the active position, you can finally drop the Blue and White marbles that have been waiting patiently in your bottom visible row.
Cracking the Mystery Row in Marble Sort Level 684
Every single Box you clear drops the counter on those giant Panels. But the middle phase of this level gets incredibly tight.
- Play the odds on the Mystery row: Keep pulling from the question mark tiles. You will occasionally pull a color you do not need yet, like Orange or Pink. Let one or two sit on the far left or right of the Conveyor Belt, but do not panic.
- Watch the lower Box shifts: As you clear the second layer of Boxes, you will expose Orange and Pink targets in the lower columns. Immediately feed them the loose marbles you accidentally pulled from the Mystery Box row.
- Prioritize the 23 counter: Your only goal right now is hitting zero on those Panels. Prioritize clearing any lower Box that has a matching color available in the top tray, even if it feels like a suboptimal route. Speed is less important than constant clearing.
- Clear the remaining visible bait: By the time the Panels are down to single digits, you should have dropped the Purple and Green marbles from your very first visible row into their matching lower Boxes.
The Post-Panel Midgame in Marble Sort Level 684
Once you hit 23 clears, the giant Panels vanish. The true board is finally revealed, and it changes the pacing completely.
- Evaluate the new Top Tray: You will now see clusters of solid colors (mostly Red up top, with scattered Green, Blue, and White) and several striped, multi-color blocks mixed in.
- Untangle the striped blocks: These multi-color chunks drop their colors in a specific order from front to back. Look at the stripe closest to the bottom of the block. That is the color that will drop first.
- Match the multi-colors to the lower Box columns: The bottom area will now likely feature Pink, Red, Green, and Yellow Boxes. Look at your striped blocks. If one has a Yellow stripe ready to go, drop it to clear your active Yellow target.
- Clear the isolated Red clusters: The top-left and top-right corners hold massive blocks of Red. Keep an eye on your lower columns. As soon as a Red Box cycles to the front, snipe those top-corner Reds to clear them out of the way.
- Maintain Conveyor Belt discipline: Even with the Panels gone, the Conveyor Belt can still jam if you pull too many multi-color blocks at once. Only pull a striped block if you can immediately use its first two colors. Clean up the remaining isolated groups, and the board will fold.
