Marble Sort Level 100 Guide: The Double Panel and Hidden Box Trap

You finally hit a major milestone, but the game is not celebrating. Marble Sort Level 100 is a brutal, cramped puzzle that wants to jam your board in the first five seconds.

The dominant colors here are bright—Yellow, Purple, Green, Pink, and Light Blue—but do not let the colorful spread fool you. The top layout is a jagged, six-column block with a missing top-right corner. It is heavily guarded. On the far left and far right wings, you have blue Panels marked with a "3". These hide entire columns of marbles until you clear three lower boxes.

Worse, the center of the board is choked with grey Hidden Boxes marked with question marks. Many of these are linked together as Connected Boxes. You cannot see what colors you are pulling, which makes planning incredibly dangerous. One blind tap can end your run.

The Front-Row Block in Marble Sort Level 100

Look closely at the board setup. The mismatch between the top and bottom is the real puzzle.

Your bottom area has four columns of Boxes. The active front row demands Dark Blue, White, Orange, and Green.

Now look at your Top Tray. The front row sitting right on the edge gives you Yellow, Purple, Green, and Pink.

Do you see the problem? Only Green has an immediate home. The Yellow, Purple, and Pink marbles have nowhere to go. They are pure bait. The game is forcing you to make a terrifying choice: leave them blocking the board, or dump them onto the Conveyor Belt just to reach the pieces hidden behind them.

If you tap Yellow and Purple right away, you eat up massive space on your Conveyor Belt. But if you do not move them, you cannot reach the Hidden Boxes that might contain the White or Dark Blue marbles you desperately need for the lower section.

The left side of the Conveyor Belt will get crowded instantly. You have to balance blind reveals with very tight belt management. Every single clear matters because it drops the counter on those side Panels from 3 down to zero.

You need a strict order of operations here. Do not spam tap the front row. We are going to open this board with surgical precision.

Surviving the First Drops in Marble Sort Level 100

The opening moves are all about clearing what you can and carefully storing what you must.

1. Send the Green down first. Grab the Green marbles from the center-right of the Top Tray front row. They drop straight into the front-right Green Box. This is your only safe opening move.
2. Take the first hit on your belt. You need to expose the Hidden Boxes behind the front line. Carefully tap the Purple marbles. Let them sit on the Conveyor Belt. Do the same for the Yellow marbles. You are sacrificing belt space to buy visibility.
3. Tap the first Hidden Box. Now that the front row is out of the way, tap one of the grey '?' boxes in the center. Pray for White, Orange, or Dark Blue. If you reveal one of these needed colors, immediately send it to its matching bottom Box.
4. Watch the Panel counters. The moment you clear that first Green Box, the blue Panels on the left and right drop their counters from "3" to "2". Your primary goal is to force two more clears to rip those panels off.
5. Hold the Pink back. Do not touch the Pink marbles in the front right yet. You need that Conveyor Belt space for the random colors spilling out of the Hidden Boxes.

The Midgame Diagonal Connection in Marble Sort Level 100

Once you clear three bottom boxes, the blue Panels vanish. The left panel reveals a solid White cluster. The right panel exposes Purple and Yellow. But clearing the front lines triggers a nasty surprise at the bottom of the board.

6. Handle the black-line Connected Boxes. As the lower stacks shift forward, you will see a thick black diagonal line tying two bottom Boxes together. Often, this connects an Orange box in column three to another box in column four. These are bottom-tied Connected Boxes.
7. Feed the connected chain slowly. Because these two boxes are locked together, one will not drop away until both are satisfied. This causes a massive traffic jam. If you fill the Orange box early, it just sits there, blocking the column behind it while you scramble to fill its twin. Only drop marbles into a connected box if you have the belt space to survive the wait.
8. Clear the left-side White. Remember that White cluster revealed when the left Panel opened? Drop it into the White bottom Box now. This is a fast, clean clear that keeps your momentum going and shifts the bottom stacks again.
9. Dig into the Light Blue cluster. The center of the Top Tray has a heavy concentration of Light Blue and Pink hiding just behind the initial grey boxes. Match the Light Blue whenever a bottom slot opens for it. This clears out the dead center of the board.

Sweeping the Back Rows in Marble Sort Level 100

The late game shifts focus to the top right corner.

10. Target the back-right Red and Dark Blue. The jagged shape of the board hides a solid block of Red and Dark Blue in the top right, sitting behind where the right Panel used to be. You need to keep your Conveyor Belt nearly empty before you start messing with this corner.
11. Clear the remaining bottom blockades. The lower area will likely ask for Pink and Yellow at this stage. Use the leftover Pink you saved from the very first row, pair it with the Pink from the center, and blast through the bottom columns.
12. Dump the final colors. With the lower Connected Boxes gone and the middle cleared, the board opens up. Send the Red and Dark Blue marbles down to finish the level. Never rush the last few taps. Verify the bottom Box color before you send a back-row marble down, or a stupid misclick will ruin a perfect run.
