Marble Sort Level 634 — Walkthrough and Solution

Marble Sort Level 634 presents a board where the left half is a solid block of grey Hidden Boxes, and the middle is cut by a diagonal line of five Tunnels. Your only free space is the right side of the Top Tray, where the bottom row shows a Tunnel on the far left, then Orange, Purple, Red, Orange, and a single White Box on the far right. Above that, you can see Light Green, Pink, Blue, Mint, White, Red, and another White.

Your starting bottom Boxes are Mint on the far left, White in the middle-left, White in the middle-right, and Mint on the far right. The game tempts you with Orange, Purple, and Red on the Top Tray's bottom row, but touching them now would leave you with no matching Box to receive them. The left column of the lower area alternates Mint, Hidden Box, Mint, Hidden Box, while the right column hides a Hidden Box at the very bottom under two Red Boxes. Clearing the front Mint and White Boxes reveals the next layer.

Marble Sort Level 634 Walkthrough

Focus on the front row: Mint on the far left, White in the middle-left, White in the middle-right, and Mint on the far right. The trap is that the Orange, Purple, and Red on the Top Tray's bottom row are decoys; you must ignore them until you have cleared the starting Boxes.

The imbalance is that the Conveyor Belt has very little room, and opening two Tunnels at once will flood it. You must clear the starting colors in the exact order given to reveal the next set of Boxes.

How to Beat Marble Sort Level 634 — Step-by-Step

Phase one: Clear the Mint and White openers

1. Tap the exposed White Box on the far right of the Top Tray.
2. Dig carefully into that right-side stack to uncover the Mint boxes hiding slightly higher up.
3. Completely ignore the Orange, Purple, and Red boxes on the bottom row of the Top Tray; leave them anchored.
4. Funnel the required Mint marbles into the far-left and far-right bottom Boxes.
5. Clearing these first four Boxes will drag the next layer up, revealing Blue, Red, and Pink bottom Boxes.

Phase two: Break the Tunnel staircase

1. Check your newly active bottom Boxes; you should have space for Blue, Red, and Pink.
2. Now you can safely drop the Red and Purple boxes that were decoys on the bottom row of the Top Tray, matching them into their respective Boxes.
3. Target the lowest rainbow Tunnel first; dropping a Tunnel spills out a sequence of hidden marbles. Ensure your Conveyor Belt has at least three empty slots before you crack one open.
4. As the bottom Tunnels clear out, you break the diagonal wall separating the board.
5. Clear the Tunnels sequentially from bottom to top, never opening two at the same time.

Phase three: Manage the Hidden Box Wall reveal

1. As you pull adjacent colored boxes, the left-side Hidden Boxes will flip and reveal their true colors.
2. Only drop a newly revealed color if you have a matching active bottom Box; the lower queues will now push up Yellow, Light Blue, and more Purple Boxes.
3. Keep a close eye on the left and right bottom columns; the grey Hidden Box tiles in the lower queues will now activate.
4. Prioritize feeding any active bottom Box that is sitting directly on top of a lower Hidden Box to reveal those mystery targets immediately.
5. Sweep up the remaining left-side wall layer by layer, never pulling a color from the deep left unless your Conveyor Belt is completely empty.

Tips & tricks

• Always keep at least three empty slots on the Conveyor Belt before opening a Tunnel.
• Watch the order of the bottom Boxes; feed them in the sequence they appear to avoid overflow.
• When Hidden Boxes flip, match their colors only if you have an available Box; otherwise, wait.

Common mistakes

• Grabbing the Orange, Purple, or Red decoys early will jam the belt.
• Opening two Tunnels simultaneously floods the belt with mixed colors.
• Ignoring the Hidden Boxes in the lower columns leaves you guessing at the end.
