Marble Sort Level 19 Walkthrough & Solution

Level 19 Board Overview: Two Tunnels and a Poisoned Center

Level 19 wants you dead inside five moves. The Top Tray is a staggered five-column setup painted mostly in Pink, Purple, and a big ugly cluster of Black parked right in the front center — exposed, shiny, and completely unplayable.

Both outer columns are capped by blue Tunnels, each showing a countdown of 3. Those arches are the real gatekeepers: every Box you clear ticks them down, and what they guard is exactly what you are starving for.

The receiver Boxes at the bottom open with Dark Blue, Dark Blue, Orange, Pink. Now scan the tray for Dark Blue. There is none within reach — one cluster is pinned under a Light Blue stack in column two, and the other is sealed inside the far-right Tunnel. Until you solve the right side of the board, the left half of the receiver row is a locked door.

The Trap in Marble Sort Level 19

The board is rigged to punish the obvious move. Column by column:

• Front center: Black marbles, wide open. There is no Black Box anywhere near the active rows. Touch them and they camp on your belt forever.
• Just behind the Black: a Purple cluster, equally exposed, equally homeless. Same story — no Purple Box up front.
• Column two: your Dark Blue, buried under a Light Blue stack. You cannot get it yet.
• Far-right column: a Tunnel on 3 guarding the second Dark Blue stash. This is your real target.
• Bottom of columns one, two, and five: exposed Orange and Pink clusters. These are your only legal opening moves, and the board knows it.

The panic play is tapping the center because it is big and available. Three Black marbles on the belt plus a Purple and your run is over before the first Tunnel even opens.

Marble Sort Level 19 Step-by-Step Walkthrough

Work the board right to left. Feed the right-side Boxes, force the Tunnels down, and pretend the center of the tray does not exist.

Opening: feed the right side, zero the Tunnel

1. Hands off the Black cluster in the front center. Seriously.
2. Tap the exposed Orange cluster at the bottom of column one. It clears the third receiver Box, and both Tunnel counters drop from 3 to 2.
3. Tap the exposed Pink cluster at the bottom of column five. It clears the fourth Box.
4. Tap the second exposed Pink cluster at the bottom of column two. A fresh Pink Box has rotated into the third slot — fill it.
5. The right Tunnel hits 0 and the arch lifts. The Dark Blue marbles you have been chasing are finally free.

Mid-game: flood Dark Blue, open the left side

The board state has flipped and the pressure is off your belt, but stay disciplined.

6. Drop the freed Dark Blue cluster from the right column.
7. Drop the Dark Blue cluster from column two — the Light Blue stack on top of it is clearable now too. Together these slam the two Dark Blue Boxes on the left.
8. Each of those clears ticks the left Tunnel down. It hits 0, lifts, and hands you the Pink and Light Blue marbles sealed behind it.
9. The receiver row starts showing Brown and Purple. Now — and only now — tap the center Purple and Brown clusters, and only when their matching Box is sitting in the front row.

Cleanup: Black goes last

Both Tunnels are open and the Dark Blue blockage is gone, so this becomes a straight sprint.

10. Match the tall Light Blue and Purple stacks in columns two and three against their newly revealed Boxes.
11. Sweep the stragglers out of the outer columns.
12. Dump the center Black block only when a Black Box finally surfaces — it is buried deeper than anything else in this level. Until then, treat the Black cluster as furniture, not a move.

Level 19 Tips Recap

• If a color has no Box in the active rows, it does not exist. That means Black and Purple for most of the run.
• Every clear moves both Tunnel counters, so chain your right-side Boxes back to back.
• Dark Blue is the whole puzzle — free it from the right Tunnel first and the left half of the board unlocks itself.
