Marble Sort Level 355 Walkthrough & Solution

Level 355 Board Overview: The Yellow-Base Block Grid

Level 355 plays on the block-grid variant of Marble Sort. Instead of a free tray of loose marbles, the board is a grid of stacked tiles feeding three target receivers, with a conveyor belt underneath that is already loaded before you make your first move. The receiver count is small — the boxes ask for just three or four tiles each — so the level is about sequencing, not volume.

The tray is built like a layer cake. Nearly every column stacks Yellow at the base, Blue in the middle, and Purple on top, with a couple of columns running shorter. Down the middle of the board sit sparkle Yellow tiles — visually shinier than the rest, but they feed their receivers exactly like normal Yellow. Around the edges, a row of arrow tiles flanks the grid: right-facing arrows on the left side push stacks to the right, left-facing arrows on the right push them back. A cluster of round Purple balls sits off the left edge of the play area, outside the main receiver flow.

The conveyor starts the level with a run of Yellow blocks, followed by a block of Pinks, and the loading slot above it is already feeding more Yellow. That means Yellow is the engine of the opening: the board hands you a steady supply before you have cleared a single stack.

The Trap in Marble Sort Level 355

The board is rigged to make you feed the wrong layer first. Here is the layout:

• Purple caps the columns, but no receiver wants it early. Most stacks end in a Purple on top. Tap it into the belt before a Purple receiver opens and you are parked with no way to clear it.
• The conveyor is pre-loaded with Yellow and Pink. The game hands you more supply than the opening receivers can take. Overfeed the belt and it jams behind tiles that have no home yet.
• The arrow tiles move entire stacks, not single blocks. A careless push shoves a whole column past its receiver. Line the stack up first, then push — or use the arrows to reposition a column you are not ready to feed.
• Sparkle Yellow tiles look special but behave like plain Yellow. They are a visual flair, not a mechanic — treat every Yellow tile the same and you will not go wrong.

Marble Sort Level 355 Step-by-Step Walkthrough

Follow the release order and the level stays clean.

Opening: clear the Yellow bases

1. Let the loading slot drop and start feeding Yellow into the matching receiver — the conveyor is already running five Yellows, and more are loading behind them.
2. Work the Yellow layer across the grid, clearing the base of each column. The sparkle Yellow tiles in the middle stacks clear exactly like the plain ones.
3. Do not touch the Purple tiles capping the columns yet. No Purple receiver is open at the start, and there is no way to park a Purple safely.
4. When the first Pinks reach the front of the conveyor, only tap them once a Pink target is active. Six Pinks are queued, so they will keep coming regardless.
5. Keep the belt moving with Yellow only. If a color has no active receiver, let it cycle past and come around again.

Midgame: peel Blue and use the arrows

6. Once the Yellow bases are gone, the Blue middles surface in column after column. Feed Blue into its receiver — the mid-game target sits on a count of three, so a few drops finish it.
7. Use the right-facing arrow tiles on the left edge to nudge whole stacks toward the receivers, and the left-facing arrows on the right to bring far columns back. Line up the top tile of a stack with an active receiver before you push.
8. Red, Green, and Orange begin arriving on the conveyor mid-solve (the queue runs Orange, Green, Blue, Green, Blue). Tap them only as their receivers open.
9. The Pinks that were queued from the start start to find homes as Pink targets cycle forward — the belt finally pays off.
10. Leave the round Purple balls on the left edge of the play area alone. They sit outside the receiver flow and clearing them is not part of the win.

Cleanup: drain the short stacks

11. By the endgame the tray has thinned to short two-block stacks — Yellow over Green, Green over Blue, Blue over Red, Red over Blue, Blue over Pink, Pink over Blue. Peel each column top to bottom.
12. Feed each color only while its receiver is active. Skipped tiles come back around on the conveyor, so there is no rush.
13. The final Blue lands in the last receiver and the level completes — the victory screen confirms the clear with the +25 coin bonus.

Level 355 Tips Recap

• Yellow is the opening color: it pads the base of nearly every column and the conveyor is pre-loaded with it.
• Arrow tiles reposition whole stacks — align a column with an active receiver before you push, and use them to move stacks you are not ready to feed.
• Purple caps the early columns and the round Purple balls sit on the left edge; neither has a receiver at the start, so do not feed them early.
• In the endgame the tray is just short two-block stacks — play only to the active receivers and let the conveyor cycle.
