Marble Sort Level 76 Walkthrough & Solution

Level 76 Board Overview: The Checkerboard Wall

Level 76 greets you with a huge checkerboard of Mystery Boxes covering the middle and upper rows, plus two Tunnels parked in the top corners behind a 3-clear countdown. None of that is the immediate problem. The immediate problem is the front row.

Sitting exposed at the front of the Top Tray is a tempting pile of Red, Dark Green, and Orange. Now look at your starting receiver Boxes: Black, Light Blue, Purple, and Dark Blue. Notice anything? There is no Red Box. No Orange Box. No Green Box. Tap that front pile and your Conveyor Belt becomes a parking lot for colors nobody wants.

The real structure of the front row, left to right: a naked Purple marble, a Light Blue Arrow Box pointing up, the Dark Green / double Red / Orange bait cluster in the dead center, then an Orange Arrow Box and a naked Light Blue on the far right.

The Trap in Marble Sort Level 76

Every layer of this board pushes you toward a mistake:

• The edges are safe, the center is not. Both flanks hold colors the front Boxes actually want. The center is pure bait.
• The second row is half-helpful. It hides an exposed Dark Blue on the left, a Green Arrow Box in the middle, and another exposed Dark Blue on the right. The Dark Blues are gold; the Arrow Box can wait.
• The Mystery Box wall forces reactive play. Almost everything in rows three and four is face-down. You cannot script a long combo — every flip dictates your next safe tap.
• The corner Tunnels need setup. Each one demands three clears before it opens, and you can only reach them by carving up the left and right walls of the grid.

Once the first wave of Boxes clears, the replacements pull from a different pool — Brown, Pink, and more Dark Blue. If your belt is already stuffed with bait colors, you have no room to adapt when the wall starts flipping.

Marble Sort Level 76 Step-by-Step Walkthrough

Opening: work the edges, ignore the middle

1. Tap the naked Purple marble on the front left into the Purple Box.
2. Tap the naked Light Blue marble on the front right into the Light Blue Box.
3. Trigger the Light Blue Arrow Box on the front left. It finishes the Light Blue requirement and opens a gap on that side.
4. Grab the exposed Dark Blue in the second row on the far left and drop it into the Dark Blue Box.
5. Mirror it: take the exposed Dark Blue from the second row on the right.
6. Stop and check your belt. It should be nearly empty — you just bypassed the entire Red and Orange trap.

Mid-game: cracking the Mystery wall

The first Boxes roll away and the new front line asks for Brown, Dark Blue, and Pink. The hidden part of the board starts waking up.

7. Watch the Mystery Boxes flip as you clear the edges. Prioritize any freshly revealed Dark Blue or Pink that matches an open Box.
8. Once a Red, Green, or Orange Box finally appears, start dismantling the bait cluster in the front center.
9. Fire the Green Arrow Box and the Orange Arrow Box the moment matching Boxes are waiting below. This guts the middle of the board in one go.
10. Keep the belt lean. A revealed Brown or Black stays put until its exact Box is showing — this mid-game is where most runs choke.

Endgame: the Tunnel release

11. Push vertically toward both top corners, clearing any Pink or Dark Blue still sitting in the top center row.
12. Watch the Tunnel countdowns. Each marble you pull from the row beneath a Tunnel ticks it down — get both to zero.
13. When a Tunnel pops, it dumps its hidden queue onto the board. Make sure your open Boxes line up with what comes out before you trigger it.
14. Sweep the stragglers. Leftover Black and Brown marbles parked from earlier reveals flow into the final Boxes to end the level.

Level 76 Tips Recap

• Front-row bait check: if the color has no Box, the block does not get tapped.
• Arrow Boxes are free clears — but only fire them when a matching Box is already open.
• Count Tunnel clears ahead of time so the corner release never catches your belt full.
