Marble Sort Level 665 — Walkthrough and Solution

This puzzle is a test of patience and foresight. The board appears straightforward, but the two Numbered Tunnels in the upper middle control everything. They only open when you have cleared exactly two lower Boxes, and the front row of the upper tray hides a trap: Green and Light Blue clusters that seem safe but will clog your belt if released too soon. The key is to focus on the Purple pairs on the right and the Orange on the left, using them to trigger the Tunnels and reveal the path forward.

At the start, the upper tray displays, from left to right: an Orange cluster, a Green cluster, a Light Blue cluster, a gap, two Purple clusters, and a Brown cluster on the far right. Behind these, Arrow Boxes point down or right, holding back additional marbles. The lower section has four columns of Boxes. The front row contains one Orange and three Purples. The two Tunnels, marked with the number 2, sit in the upper middle, waiting to release their contents once two lower Boxes are cleared.

Your first moves must clear the two Purple clusters on the right side of the front row. Each tap sends Purple marbles down to match the Purple Boxes in the front line, clearing them. As soon as the second Box clears, the Tunnels' counters drop to zero, and they immediately dispense a Green cluster and a Yellow cluster into the center gap. Then, tap the Orange cluster on the far left to clear the Orange Box. The Green and Light Blue clusters in the front row remain untouched, but now you have room to work with the newly revealed lower Boxes.

The main trap is the Green and Light Blue clusters in the front row. They look like obvious targets, but their matching lower Boxes are buried under the Orange and Purple stacks. If you tap them early, the marbles will sit on the Conveyor Belt, wasting space and causing a jam. Only clear them when their corresponding Boxes are visible and at the front of the lower stack.

How to Beat Marble Sort Level 665 — Step-by-Step

Phase one: Opening the Gates

1. Tap the Purple cluster on the far right of the front row.
2. Tap the second Purple cluster next to it.
3. Watch the Tunnels release a Green and a Yellow cluster.
4. Tap the Orange cluster on the far left to clear its Box.

Phase two: Managing the Middle

1. Match the newly released Green and Yellow clusters with their corresponding lower Boxes.
2. Clear the Light Blue cluster only when a Light Blue Box is visible at the front of the lower stack.
3. Focus on the center-left area to clear blocks under the Yellow Arrow Boxes, enabling them to drop.
4. When Brown clusters appear on the right, match them as soon as a Brown Box is at the front.

Phase three: Final Clearing

1. Clear the Brown right-pointing Arrow Box on the left flank to unlock the left column.
2. Match any Red clusters that appear, but be careful not to leave them stranded on the belt.
3. Finish off the remaining Green and Purple clusters from the top corners.

Tips & tricks

• Always check the lower stack before tapping any cluster; only tap when the matching Box is at the very front.
• Keep the Conveyor Belt as empty as possible; avoid clogging it with colors that have no immediate match.
• Watch the dropping animations of Arrow Boxes to know exactly which color is active before making your next move.

Common mistakes

• Tapping the Green or Light Blue clusters too early, which fills the belt and causes a jam.
• Releasing colors like Pink or Blue before their Boxes are accessible, stranding marbles on the belt.
• Rushing the final phase without waiting for the Arrow Boxes to finish dropping, leading to misjudgment of available colors.
