Marble Sort Level 508 — Walkthrough and Solution

Marble Sort Level 508 spreads a U-shaped Top Tray around a central 3x3 Panel that displays a large "16". That number means you must empty sixteen bottom Boxes before any center marble becomes available. The initial bottom demands are Brown, Yellow, Purple, and Light Green from left to right. Behind those sit Dark Green, Red, Yellow, and Light Blue in the second row. The early game revolves entirely around the outer ring, so any careless pick from the upper corners will jam your Conveyor Belt.

The board's trap is a mismatch between what the bottom Boxes need and what sits within easy reach. Yellow for the second Box appears only midway up the right edge of the Top Tray. Light Green for the far-right Box rests alone on the bottom row of the Top Tray, next to colors you cannot use yet. Meanwhile, the left side of the Top Tray holds Pink, Light Blue, and Dark Blue marbles that look tempting but belong to Boxes buried deep in the queue. If you pull those early, they will occupy belt slots uselessly while you struggle to clear the 16 required clears.

Marble Sort Level 508 Walkthrough

The front row of bottom Boxes demands Brown, Yellow, Purple, and Light Green in that exact order from left to right. The second row, which appears after the first clears, needs Dark Green, Red, Yellow, and Light Blue. The third row will later reveal more colors, but you cannot see them until the Panel opens.

Your only safe plays at the start come from the bottom section of the Top Tray and the right edge. The upper-left corner holds Pink, Light Blue, and Dark Blue, but those are decoys. The center Panel's counter drops only when a bottom Box fully clears, so every tap must feed an active Box. The imbalance is that you need Yellow early, but the only accessible Yellow is on the right edge, and the only Light Green sits wedged between unused colors on the bottom row.

How to Beat Marble Sort Level 508 — Step-by-Step

Phase one: Clear the outer row

1. Tap the Brown marble located on the bottom section of the Top Tray to start filling the leftmost Brown Box.
2. Next, tap the Purple marble sitting beside that Brown and direct it into the third column's Purple Box.
3. Move to the right side of the Top Tray; locate the Yellow marble on the edge and send it into the second column's Yellow Box.
4. From the bottom row of the Top Tray, pick the Light Green marble and deliver it to the far-right Box.
5. Leave the Pink, Light Blue, and Dark Blue marbles on the upper left untouched for now.
6. Once the front row clears, the new front row shows Dark Green, Red, Yellow, and Light Blue. Find the Red marble on the bottom edge of the Top Tray and route it into its Box.
7. Then locate the Light Blue marble on the bottom edge and guide it into the fourth column's Box.

Phase two: Unlock the center

1. Repeat the perimeter-clearing process. Every time a bottom Box clears, the Panel's counter decreases. Continue feeding the visible outer colors until the counter hits zero.
2. When the Panel vanishes, pause before tapping randomly. The bottom Boxes now reveal a Lock and Key mechanic.
3. A locked Purple Box blocks the left column. To clear it, you must first clear the Box that holds the key.
4. Inspect the newly exposed center marbles and identify the exact colors needed for the key-bearing Box. Prioritize that Box above all others.
5. Drop the necessary center marbles onto the Conveyor Belt to clear the key Box.
6. Once the key unlocks the left column, the belt pressure eases because you can now access the deeper rows.

Phase three: Cleanup

1. After the lock opens, you will likely see leftover Blue, Pink, and Dark Green Boxes in the lower columns.
2. Pull the Dark Blue and Pink marbles from the upper corners of the Top Tray, which you deliberately saved, and feed them into those remaining Boxes.
3. Keep your matches grouped in sets of three so that no single marble lingers on the belt. The board is open now, so a steady rhythm will finish the level cleanly.

Tips & tricks

• Always check the bottom Boxes before tapping any marble; only feed a color that matches an active Box.
• Leave the upper-left corner marbles alone until the Panel opens; they are needed for the final cleanup.
• When the Lock and Key appears, focus entirely on the key Box; unlocking the left column is the turning point of the level.

Common mistakes

• Grabbing Pink, Light Blue, or Dark Blue early clogs the belt and prevents you from clearing the 16 required Boxes.
• Ignoring the Lock and Key mechanic and tapping center marbles randomly can strand a key color on the belt, causing a jam.
• Forgetting to save the upper-corner marbles for the endgame leaves you without the colors needed to clear the final hidden rows.
