Marble Sort Level 159 Walkthrough & Solution

Level 159 Board Overview: Mystery Tiles Over a Loaded Belt

Level 159 opens with a five-column tray where the two outer columns are short and the center column runs tallest. Gray mystery ’?’ tiles cap several columns, and the center of the board is pinned under special numbered tiles and a blue Key tile that stay in place through most of the level. A large cluster of Dark Blue marbles sits loose in the funnel below the tray, ready to drop the moment a Dark Blue receiver opens.

The Conveyor Belt starts already loaded: Dark Red, a long run of Green, four Pink, more Green, another Dark Red, and a closing run of Orange. That queue is the board’s biggest trap — most of it has no receiver at the start.

The receiver boxes tell the real story. At the opening only the Orange and Dark Blue boxes are unlocked; the Blue and Brown boxes sit locked. Behind them the rows ask for Dark Red, Light Cyan, Dark Blue, Orange, Yellow, Bright Green, Dark Pink, and Gray. The whole level is a conveyor-management puzzle: unlock the front row, then ride the belt through the dark colors into a light-color cleanup.

The Trap in Marble Sort Level 159

The opening board is arranged to make you grab the wrong colors first. Here is the layout:

• Only two unlocked boxes: the Orange and Dark Blue receivers are the only ones open at the start. Blue and Brown are visibly locked, and the rest of the rows have not unlocked yet.
• The loaded belt: the Conveyor Belt leads with Dark Red, Green, and Pink. None of those colors has an open box in the first row, so pulling them early jams your queue.
• The mystery ’?’ tiles: several columns are capped by gray ’?’ tiles. Their reveals can change your reads, so clear beneath them first and reveal them only once their columns open.
• The center Key tile: the blue Key tile and numbered blocks sit in the middle column and hold part of the board hostage. Play around them until the column naturally empties.
• Bait colors: Green and Pink make up most of the opening queue with zero receivers on the first row. Let them ride the belt until the Bright Green and Pink boxes unlock.

The board wants you to match the belt as it feeds. Do that and the queue backs up before the first row clears. Instead, feed only the colors with open boxes — Orange and Dark Blue — and let the belt carry the rest.

Marble Sort Level 159 Step-by-Step Walkthrough

The level is a conveyor-management puzzle: the target colors rotate as boxes unlock and fill. Follow the release order.

Opening: feed the unlocked receivers

The first row unlocks Orange and Dark Blue. Everything else on the board is bait until the boxes cycle.

1. Tap the Orange marbles already waiting at the tail of the Conveyor Belt into the open Orange box.
2. Drop the Dark Blue cluster from the funnel under the tray into the Dark Blue receiver — it is the loosest marble supply on the board.
3. Keep the Orange box fed. Orange appears in multiple box rows, so it stays in rotation for most of the level.
4. Do not touch the Green and Pink runs leading the belt — their boxes are still locked.
5. Leave the locked Blue and Brown boxes alone, and skip any Blue or Brown marble that surfaces in the tray.
6. Work the short outer columns for the Light Cyan marbles — a Light Cyan box sits in the second and third box rows, so it becomes useful early.

Midgame: clear the dark colors

Once the front row fills, the belt cycles and the dark colors finally have homes.

7. Release the Dark Red marbles from the belt into the Dark Red box waiting in the second row.
8. As the side columns empty, the mystery ’?’ tiles lose their cover — reveal them one at a time and fold each revealed color into whichever receiver is open.
9. Keep feeding Orange and Dark Blue; the queue narrows to exactly those two colors as the midgame progresses.
10. Start releasing the Green marbles only once the Bright Green boxes unlock in the lower rows.
11. Fill the Yellow boxes when the Yellow marbles surface from the tray or the belt.
12. The Blue and Brown boxes unlock mid-level as well — feed any Blue or Brown marbles held back in the opening.

Cleanup: finish on the light colors

The tray is nearly stripped; only the light and mixed colors remain.

13. Finish the Light Cyan boxes (they appear in three rows) and feed the remaining Light Blue marbles as their boxes arrive.
14. Play the Dark Pink and Gray marbles into the bottom-row receivers once they unlock.
15. Match the last Turquoise and Dark Grey marbles — the endgame tray holds a Turquoise pair and a single Dark Grey marble still riding the belt.
16. Only release a color whose box is in the front or second row. Let the final clears pull the stragglers down, and the level ends.

Level 159 Tips Recap

• Orange and Dark Blue are your only opening targets — the belt’s Green and Pink runs are bait until their boxes unlock.
• The conveyor opens loaded with Dark Red, Green, and Pink. Never pull a color with no open box.
• Reveal the mystery ’?’ tiles only after their columns clear, and play around the center Key tile instead of forcing it.
• The endgame is a light-color cleanup: Light Cyan, Light Blue, Yellow, Turquoise, Dark Grey, and Pink finish the board.
