Marble Sort Level 7 Walkthrough & Solution

Level 7 Board Overview: The Striped Lockdown

Level 7 stacks the Top Tray into a tight 4x4 grid and then blinds you. Rows one and three are solid Mystery Boxes. Row two shows flat colored blocks: Yellow, Light Blue, Yellow, Purple. Row four — the ready-to-drop line — holds Yellow, Light Blue, Red, and Light Pink.

Down below, four deep columns of Boxes open with a front line of Light Pink, Purple, Yellow, Purple. Your colors this level are Yellow, Light Pink, Light Blue, Red, and Purple.

Here is the clash that defines the board: two of your four active Boxes are screaming for Purple, and the only Purple block in sight is stuck in row two behind a wall of Mystery Boxes. Meanwhile, two free clusters — Light Blue and Red — sit right up front begging to be tapped, with zero matching Boxes to catch them.

The Trap in Marble Sort Level 7

The bottom columns tell you the exact order of operations:

• Column one: Light Pink on top; Purple and Yellow buried under it.
• Column two: Purple up front, hiding Light Pink and Red.
• Column three: Yellow covers Purple and Light Blue.
• Column four: Purple sits over Yellow and Light Blue.

So the Light Blue and Red clusters in the front row are pure bait. Drop them now and they hog your Conveyor Belt for half the level. The corners — Light Pink and Yellow — are your only safe first taps. Clearing them forces the hidden rows to drop and eventually hands you the Purple you need.

Marble Sort Level 7 Step-by-Step Walkthrough

Opening: work the corners

1. Tap the Light Pink cluster on the bottom right of the Top Tray. It routes straight into the far-left Light Pink Box.
2. Tap the Yellow cluster on the bottom left. It drops into the third column’s Yellow Box.
3. Hands off the Light Blue and Red clusters in the middle. They stay parked.
4. The first Mystery Box row drops into play and flips over.
5. Scan the reveals on the outer edges. You are hunting Purple — two bottom Boxes are starving for it.

Mid-game: cash in the bait

6. Drop the newly exposed Purple marbles into both Purple Boxes. This is the level’s biggest bottleneck — break it and you win.
7. If a Purple stays trapped, park exactly one off-color cluster on the belt to dig it out. You can afford it precisely because you skipped the bait earlier.
8. New Boxes rotate into the active slots, and finally Light Blue and Red Boxes appear.
9. Tap the Light Blue cluster that has been waiting in the front row since the start.
10. Tap the Red cluster right after. Both flush home instantly and the board breathes again.

Cleanup: the last hidden row

11. The final Mystery Box row slides down. Your lean belt has room for whatever awkward colors flip over.
12. Focus fire on one color at a time — a full clear cycles a fresh Box in faster than four half-filled ones.
13. Drain the remaining solid blocks from the top center to finish the level.

Level 7 Tips Recap

• Your first two taps are always the corners: Light Pink, then Yellow. Fixed order, no freestyle.
• Belt space you refuse to spend early is what buys your mid-game dig for Purple.
• Bait clusters are only safe to release after their Boxes rotate into the active row — watch for Light Blue and Red.
