Marble Sort Level 669 presents a large board with a massive panel on top that hides the central area. Two Gift Boxes, each requiring two clears, sit on the far left and right. The key to victory is to clear the bottom boxes in order from left to right, starting with Red, Green, Black, and Purple, while ignoring the loose marbles in the center until later.
The Top Tray holds heavy clusters of Purple and Green on the left side, and Red and Black on the right side. In the middle, beneath the panel, there are loose Pink, Purple, and Orange marbles resting on a tan blocker. These center marbles are a trap because Pink and Orange boxes appear later in the sequence.
Marble Sort Level 669 Walkthrough
The front row of bottom boxes demands, from left to right: Red, Green, Black, and Purple. These colors match the heavy clusters on the ledges, so you can clear them quickly.
The main risk is sending the loose center marbles to the Conveyor Belt too early, which would occupy slots needed for the required colors. So, you must work from the outer edges inward.
How to Beat Marble Sort Level 669 — Step-by-Step
Phase one: Clear the front row
- Route the Red cluster from the right ledge to the Red box on the front left.
- Deliver the Green cluster from the left ledge to the Green box in the second slot.
- Feed the Black cluster from the far right to the Black box in the third slot.
- Drop the Purple cluster from the far left into the Purple box on the right.
- Leave the loose Pink and Orange marbles untouched for now.
Phase two: Unlock the Gift Boxes
- After the front row clears, the panel counter drops from 9 to 5, and the next row slides forward: Purple, Black, Black, Pink.
- Use the exposed Black and Purple marbles near the outer columns to feed the new boxes.
- Now you can safely send the loose Pink marbles from the center to clear the Pink box on the far right.
- Clear marbles adjacent to the Gift Boxes to pop them open, revealing new marbles on the edges.
- Continue feeding the second and third rows of bottom boxes, which include Black, Green, and Orange, until the panel counter reaches zero.
Phase three: Survive the vault spill
- When the panel shatters, a large payload of Blue, Light Blue, Black, and Orange clusters is revealed.
- Manage the loose marbles that slide down the center funnels, keeping them away from the belt.
- Prioritize Pink and Green as they appear in the bottom boxes, finding them in the spilled pile.
- Check that a Light Blue box is at the front before sending the Light Blue clusters down.
- Match the remaining Blue and Orange clusters to the final rows to finish the level.
Tips & tricks
- Always check the front box before sending any marbles to avoid jamming the belt.
