Marble Sort Level 655 — Walkthrough and Solution

Marble Sort Level 655 is a Hidden Box stage where a large U-shaped track wraps around the top tray, packed with grey question marks that hide unknown colors. The board also features six solid marble blocks blocking the lower part of the top tray, and a central track with mixed-color blocks that must be handled late. The answer is to clear the six gatekeeper blocks in a precise sequence that matches the bottom queue's demands, then use the revealed Hidden Boxes as a secondary supply, and finally handle the split-color blocks only when your conveyor has space.

At the bottom of the top tray, from left to right, stand six blocks: Blue, Green, Purple, Light Blue, Pink, and another Purple. Above these, the outer horseshoe is filled with Hidden Boxes, and inside that, a central track holds solid Red, Orange, Pink, and Brown blocks, but the top of that track is loaded with split-color blocks like Light Blue + Orange, Purple + Green, and Brown + Yellow. Your bottom queue starts with two Light Blue Boxes on the left, two Purple Boxes on the right, and empty spaces behind them that will shift forward as you clear.

Marble Sort Level 655 Walkthrough

Your front row of bottom Boxes initially demands Light Blue on the left and Purple on the right. Behind those, the next row will ask for Pink and Blue, then later Green, Orange, and Brown.

The specific trap is the far-left Blue block in the top tray. It looks harmless, but if you drop it before the bottom queue asks for Blue, it will sit on your conveyor belt and block the colors you need to clear the opening. You must wait until the bottom row for Blue is exposed.

How to Beat Marble Sort Level 655 — Step-by-Step

Phase one: Clear the Gatekeepers

1. Tap the Light Blue block, which is the fourth from the left at the bottom of the top tray. This sends a wave of Light Blue marbles down to fill the two Light Blue bottom Boxes on the left.
2. Next, tap the first Purple block, sitting third from the left. This starts clearing the Purple bottom Boxes on the right.
3. Then tap the second Purple block on the far right. With both Purple blocks sent, the right-side Purple Boxes are cleared, and the queue shifts forward.
4. After the queue moves, your front row will show Pink and Blue. Tap the Pink block, which is fifth from the left, to clear the Pink Box.
5. Finally, now that the Blue Box is exposed in the front row, tap the far-left Blue block that you avoided earlier. It drops and clears that Blue Box.

Phase two: Reveal and Use the Hidden Box Track

1. As the bottom queue slides up, Green, Orange, and Brown Boxes come to the front. Watch for them.
2. On the inner U-track, you now have access to the solid Orange and solid Brown blocks. Release each only when the matching bottom Box is in the front row.
3. Keep an eye on the outer Hidden Boxes. When one reveals a color that matches a front-row Box, tap it immediately to clear that Box.
4. If a Hidden Box shows a color you don't need yet, leave it alone. Let it stay in the top tray, even if it tempts you.

Phase three: Survive the Split-Color Finish

1. Do not tap a split-color block unless your conveyor belt has at least three empty slots, because it will release multiple colors at once.
2. For the Light Blue + Orange split block at the top left of the center track, wait until a Light Blue or Orange Box is in the front row.
3. If a split block drops colors that don't match the front row, park those marbles on the conveyor belt. Don't panic.
4. Use the remaining single-color marbles from the outer Hidden Boxes to clear the front row Boxes. As the belt cycles, the parked split-colors will eventually match new Boxes that come up, and you can clear them.
5. Once the belt is clear of those trapped split-colors, drop the final remaining blocks to finish the stage.

Tips & tricks

• Always read the bottom queue before tapping anything in the top tray; the order of your taps must match the front-row demands.
• Treat the Hidden Boxes as a backup: use them to clear a Box when you need a quick color, but don't rely on them for your main plan.
• When a split-color block is ready, make sure your conveyor has room, then release it and immediately use single-color marbles to clear the front row.

Common mistakes

• Tapping the far-left Blue block too early is the most common error; it clogs your belt and delays the entire opening.
• Cracking a split-color block without checking your belt space can flood the conveyor with colors you can't use, causing a jam.
• Ignoring the bottom queue and clearing colors in a different order than the Boxes demand will leave dead marbles on the belt and block progress.
