Marble Sort Level 155 Walkthrough & Solution

Level 155 Board Overview: The Orange Flood

Level 155 opens on a five-column tray with a lopsided setup. The far-right column is nothing but four Oranges stacked floor to ceiling, and the conveyor queue behind it is stuffed with eight more. Across the board, the left column and the tall five-slot center column are both Purple-heavy, with a few Blue marbles buried mid-depth in column two.

The receiver boxes start in two rows of four. The front row asks for Blue, Purple, Purple, Blue; the row behind it asks for Blue, Orange, Orange, Orange. That gives Oranges three boxes waiting, Purples two, and Blues three — while Pink, White, Green, Light Blue, and Dark Grey have no box anywhere in the first two rows.

The green x2 pads at the base of the columns mark your scoring lanes, and the level’s real difficulty is pacing: there are far more Oranges on the board and on the belt than the boxes can absorb at once, so a careless opening jams the whole queue.

The Trap in Marble Sort Level 155

The board is rigged to make you grab everything the belt shoves at you. Resist.

• The Orange flood: a full four-Orange column plus a long Orange run on the conveyor, but only three Orange boxes. Feed them steadily, never in one burst, or the queue backs up and you lose the ability to move anything else.
• The Dark Grey bait: two Dark Grey marbles sit at the head of the conveyor queue, and no Grey box exists in the first two box rows. Letting one onto the belt wastes a slot you cannot clear.
• The buried Purples: the left column stacks Purple, Pink, Purple, Purple — every useful tap exposes a Pink underneath. The center column hides a Green and a Dark Blue between its Purples.
• The junk stack: column four is Pink, White, White, Green, a column of pure bait from top to bottom. Nothing in it has a home early on.

Marble Sort Level 155 Step-by-Step Walkthrough

Pace yourself on Oranges, take Purples from the top, and the board opens up on its own.

Opening: feed the front row

1. Tap the two Dark Blue marbles in column two into the Blue boxes — the front row asks for Blue on both ends, with a third Blue box waiting behind.
2. Feed the Purples from the tall center column first. Its top two slots are stacked Purple on Purple, so you get two safe taps into the front Purple boxes before any risk appears.
3. Take the top Purple from the left column into the second Purple box, then stop — the next marble down is a Pink with no box.
4. Open the right column by dropping its top Orange into an Orange box. The back row holds three Orange boxes, so there is real room.
5. Keep placing Oranges as the belt feeds them, one at a time, so the queue keeps moving without ever hitting the Dark Greys at its head.

Midgame: crack the center column

6. When the front Purple boxes fill, they cycle away and the back row slides forward. The Orange boxes stay your pressure valve for the whole level — keep them clear.
7. Dig out the rest of the center column. With its Purples gone, the Dark Blue and Green inside it come into view, and the entire middle of the tray finally opens up.
8. Finish the third Blue box with the Dark Blues arriving on the conveyor as they come.
9. Swing back to the left column and drop its two remaining Purples into any Purple box that cycles back to the front row.
10. Leave the Pink in the left column alone, and do not touch the Pink-and-White stack in column four — neither color has a box yet.

Cleanup: strip the stragglers

11. Once the boxes cycle to the remaining colors, start with the Green trapped at the bottom of column four, then clear the Whites above it as their box appears.
12. Keep the last Oranges flowing off the belt into the final Orange boxes before they cycle out.
13. Feed the leftover Purples from the left column and the center as their boxes come back around.
14. From here, play only to the active front row — every marble left on the tray has a box somewhere in the cycle, and the last few fall into place on their own.

Level 155 Tips Recap

• Oranges are everywhere but three boxes must absorb them all — place one at a time and never dump the queue.
• The two Dark Greys at the head of the conveyor are bait with no box; never let one onto the belt.
• Take Purples from the top of the center column first: two safe taps before anything risky is exposed.
• The Pink-and-White column is pure junk — ignore it entirely until the boxes cycle to its colors.
