Marble Sort Level 7 is a sandwich of known and unknown, and the unknown half does all the hurting. Five shades are in play — Purple, Red, Light Blue, Light Pink and Yellow — but only two rows of the tray are actually readable; the other two are solid Mystery Boxes. The board wants you to fling colours you don't need yet. Hold your nerve.
The bottom edge of the tray, read from the right this time, gives you Light Pink, then Red, then Light Blue, then Yellow. A wall of four Mystery Boxes sits just behind them, followed by a row of flat blocks and then yet another Mystery row. It's a layered mess built to hide your next move.
Marble Sort Level 7 Walkthrough
Your active Boxes run Light Pink, Purple, Yellow, Purple. Here's the snag: a Red cluster and a Light Blue cluster sit free in the middle of the tray, looking like easy points, but neither colour has a Box waiting for it. Drop them and they hog the belt.
Dig into the stacks and the real order surfaces. The leftmost column tucks Purple and Yellow beneath its Light Pink. The next column tucks Light Pink and Red beneath its Purple. The third tucks Purple and Light Blue beneath its Yellow, and the fourth tucks Yellow and Light Blue beneath its Purple. The corners are your only safe entry.
How to Beat Marble Sort Level 7 — Step-by-Step
Beat the front-row bait
- Send the Light Pink on the bottom-right corner down into the far-left Light Pink Box.
- Send the Yellow on the bottom-left corner into the mid-right Yellow Box.
- Leave the middle Red and Light Blue exactly where they are.
- Clearing those two corners drops the first Mystery row into play and flips its hidden tiles.
- Now scan the revealed edges for Purple — that's what the two middle Boxes are starving for.
Survive the mid-board reveal
- Route the exposed Purple marbles into the two Purple Boxes up front. This is the level's real choke point.
- If you have to, park one off-colour cluster to dig out a stuck Purple — you've got the room because you skipped the Red and Light Blue earlier.
- Fresh Boxes slide up, and Light Blue and Red targets finally appear.
- Now release those middle Red and Light Blue marbles that have been waiting since the first tap. They flush out and clear a big slice of the board.
Push the final layers
- The last Mystery row drops down. Your lean belt has room to catch any awkward flips.
- Chase whichever Box is closest to clearing — a full clear frees space and keeps the chain rolling.
- Don't scatter your drops across four half-empty Boxes. One colour at a time.
- Drain the last solid blocks from the top centre to close it out.
Tips & tricks
- The middle columns are dead until the corners clear — treat Red and Light Blue as traps, not targets.
- Two Purple Boxes sit up front, so every revealed Purple outranks everything else.
- The lean belt you built early is what lets you dig for Purple without jamming.
Common mistakes
- Dropping the middle Red or Light Blue at the start. Neither has a Box, so both loop on the belt.
- Scattering late drops across too many half-filled Boxes, which stalls the chain and strands colours.
Marble Sort Level 7 FAQ
Why does my Conveyor Belt flood on Marble Sort Level 7?
You tapped the middle Red or Light Blue cluster before any matching Box existed. Neither has a front-row Box, so they loop on the belt. Clear the two corners first.
Which color do I clear first on Marble Sort Level 7?
Light Pink on the bottom-right, then Yellow on the bottom-left. Clearing those two corners is what drops the Mystery Box row and unlocks the Purple you need.
How many moves does it take to clear Marble Sort Level 7?
Roughly nine taps across three phases — the two corners, the Purple dig, then the Red and Light Blue release and the final Mystery row cleanup.
Do I need boosters to beat Marble Sort Level 7?
No. Clear the two corners and the hidden Purples surface on their own. Save boosters for boards with hidden Boxes or locks.
What happens if I drop the middle Light Blue early?
It lands on the Conveyor Belt with no matching Box, so it sits there and eats the space you need to dig for Purple. The run stalls before the reveal.
