Marble Sort Level 29 Walkthrough & Solution

Level 29 Board Overview: Front-Row Decoys and a Tunnel on a Timer

This board greets you with a heavy wall of Dark Blue, Brown, Red, and Orange, and it wants you to panic. The Top Tray is packed tight, the back row is five gray Mystery Boxes you cannot read, and a Tunnel stamped with a 3 sits in the middle of the board guarding everything behind it.

Your starting receiver Boxes ask for Orange, Light Purple, Orange, and Dark Blue. Now check the front row of the Top Tray: Red, Dark Blue, Brown, Dark Blue. Only two of those four blocks have anywhere to go — and they are both Dark Blue. The Red and Brown are pure bait, and the Conveyor Belt has no patience for either of them.

The Trap in Marble Sort Level 29

The bait works because the wrong colors look so available. Here is what each column is really doing:

• Front-left Red: there is no Red Box anywhere near the surface. One hides at the very bottom of the far-right stack, so this marble has no home until the endgame.
• Front Brown: same story. The Brown Boxes are buried under Light Purple on one side and Orange on the other. Drop it early and it just squats on the belt.
• Row two: this is where the real game lives — Brown, Light Purple, Dark Blue, Orange, and Green, all locked behind the front line.
• Back rows: the Tunnel plus a full wall of five Mystery Boxes. You need three Box clears before the Tunnel pops and the board opens.

So the early game is a surgical strike: pull the Dark Blues, uncover Light Purple and Orange, and never let a homeless color touch the belt.

Marble Sort Level 29 Step-by-Step Walkthrough

Space is tight, so follow the order instead of improvising.

Opening: feed the Dark Blues, dodge the bait

1. Tap the Dark Blue block in the front row, second column from the left.
2. Tap the Dark Blue block on the far right of the front row. Both groups feed the far-right Dark Blue Box, and a Green Box cycles up behind it.
3. Leave the front-left Red and the front Brown untouched. They are traps, not options.
4. Tap the Light Purple block you just exposed on the left side of row two. It clears the middle-left Box, which flips to Dark Blue.
5. Drop the Dark Blue block sitting in the middle of row two into that fresh Dark Blue Box.

Mid-game: the Tunnel pops

That is three Boxes cleared — exactly what the Tunnel was counting.

6. The Tunnel hits zero and spills extra Light Purple and Dark Blue blocks onto the board.
7. Tap the Orange block in row two. It clears the middle-right Box and brings up a Brown Box.
8. Now the front-row Brown is finally legal. Drop it in, and the middle-right stack flips to Light Purple.
9. Feed the Light Purple blocks the Tunnel just gave you into that Box.

Cleanup: surviving the Mystery Box wall

10. The five back-row Mystery Boxes start flipping over, mostly Light Blue and Purple. Meanwhile the far-left and far-right stacks are both asking for Green — drop the Green block from the far right of row two.
11. Work through the revealed back rows. If a Mystery Box shows a color with no active Box, park it on the belt and keep going.
12. Tap the front-left Red only once the far-right stack grinds down to its Red Box. Clean up the remaining Purple and you are done.

Level 29 Tips Recap

• At the start, exactly two front-row blocks are playable, and both are Dark Blue.
• Three Box clears crack the Tunnel — count them so the board flip never surprises you.
• Red and Brown only become safe once their Boxes surface; touching them early is how runs die.
