Marble Sort Level 341 Walkthrough & Solution

Marble Sort Level 341 Board Overview: The Locked-Center Grid

Level 341 plays on the tile-grid variant of Marble Sort: six columns of square tiles packed into the tray, sliding down toward the conveyor and the receiver Boxes below. The top row is fully visible from the first tap — Green (with a key icon) on the far left, then Yellow, White, Orange, and Blue running across to the right.

The trouble starts in the second and third rows. Pink and more Green sit on the flanks, but the middle of the tray is sealed by dark lock tiles — you can see them sitting between the columns, and everything buried underneath is invisible until the locks open. The Boxes at the bottom start by asking for White, Green, and Blue, with Pink, Yellow, and Purple cycling in as the rows fill.

In other words, the level front-loads your safe colors on the outside and hides the rest behind locks. Clear the rim, let the key blocks reveal themselves, and only then attack the center.

The Trap in Marble Sort Level 341

The middle of the tray is rigged to stay out of reach. Here is the layout:

• The center columns are locked from the start: dark lock tiles sit between the second and third rows of the grid, sealing whatever waits underneath them. You cannot plan the middle of the board until those open.
• Key tiles are your unlockers: a Green key block rides the far-left column and a Blue key block sits on the right, with grey key blocks buried in the center. They are exposed only after the front rows clear.
• Only the flank colors have open Boxes at first: White, Green, and Blue are safe early; Pink, Yellow, Orange, and Purple all wait for their Boxes to cycle forward.
• The belt can jam fast: once the center unlocks, the conveyor runs a long batch of Blue tiles with White and Green mixed in — feed it carelessly and the queue backs up before the Boxes catch up.

Marble Sort Level 341 Step-by-Step Walkthrough

Clear the rim before you touch the locks. Follow the release order.

Opening: clear the rim

1. Tap the Green key tile on the far left of the top row straight into a Green Box.
2. Feed the Yellow and White tiles next to it — both have Boxes open in the first rows.
3. Take the Orange and Blue from the right half of the top row as their Boxes cycle forward.
4. Move down to the second row and drop the Pink on the far left into a Pink Box.
5. Feed the Green tiles on the right side of rows two and three, then the White tile on the lower-left flank. Do not touch the dark lock tiles in the middle — there is no way through them yet.

Midgame: unlock the center

Once the front rows thin out, the key blocks hidden under the top tiles are exposed: a Green key on the left, a Blue key on the right, and grey key blocks in the center. These open the sealed middle columns.

6. Feed the Green key block and the Blue key block as soon as their matching Boxes sit in the front row.
7. When the grey key blocks reach the front, use them to unlock the dark tiles sealing the center columns.
8. With the center open, the belt starts running a long batch of Blue tiles — feed them in runs, clearing several Boxes in a single pass.
9. Mix in the White and Green tiles riding the same batch as their Boxes slide forward.
10. Keep the conveyor moving, but never park a color whose Box has already closed — the unlocked center spills tiles quickly.

Cleanup: feed the stragglers

The end frame shows the grid completely empty and every remaining tile riding the bottom conveyor: a line of Pink, a batch of Green, a run of Purple, and a pair of Orange.

11. Play only to the active front row — Pink, Green, Purple, and Orange are the last colors to feed.
12. Let the belt cycle; each color lands as its Box opens at the bottom.
13. Finish the last Boxes as the conveyor empties — the level completes the moment the final tile drops.

Level 341 Tips Recap

• The center columns start sealed by dark lock tiles — clear the flanks first and let the key blocks reveal themselves.
• Only feed colors with an open Box: White, Green, and Blue open the level; Pink, Yellow, and Purple wait for their rows.
• Midgame the belt runs long batches of Blue — feed them in runs instead of one tile at a time.
• In the endgame the grid is empty; just cycle the belt and let the last Pink, Green, Purple, and Orange fall into their Boxes.
