Marble Sort Level 628 — Walkthrough and Solution

Marble Sort Level 628 is a lock-and-key puzzle where you must lower two blue gates before you can touch the central columns. The trick is to clear the outer edges in the right order and never let the Conveyor Belt jam with Purple.

The board has a top tray split into left and right sections. On the far left, from top to bottom, you see Red, Blue, and a dotted Green (the key). On the far right, there are two stacked Orange marbles with a single Red above them. The middle holds a striped pillar over a rainbow ring and a blue block. Under the left gate, the column contains Orange, Blue, Red, and Purple. Under the right gate, the stack is Purple, Purple, Green, and Purple from top to bottom. The bottom boxes in front are Orange, Orange, Green, and Red, left to right. Behind them are Brown, Orange, Purple, and Blue, with more boxes further back.

Marble Sort Level 628 Walkthrough

The front row demands two Orange, one Green, and one Red. You must satisfy these before anything else. The rear boxes will rotate forward only after you clear the front ones.

The biggest trap is the dense Purple stack on the right-center. If you unlock that side and drop Purple before a Purple box is available, the belt will jam. You need to clear the Orange and Green boxes first to bring the Purple box to the front.

How to Beat Marble Sort Level 628 — Step-by-Step

Phase one: Unlock the first gate

1. Slide the two Orange marbles from the far right end of the top tray into the leftmost Orange box.
2. Direct the lone Red marble that was above those Oranges into the Red box on the right.
3. Release the top Red and the Blue from the far left edge onto the Conveyor Belt to expose the dotted Green underneath.
4. Send that dotted Green down the belt. As it reaches the Green box, the left gate's counter drops from 2 to 1.
5. Do not tap any Purple yet. Your belt holds a Blue and a Red; leave them there while the front boxes clear and rotate.

Phase two: Clear the center-right

1. When the new front row appears (Brown, Orange, Purple, Blue from left to right), locate the second dotted Green marble and drop it. Both gates now open.
2. Now that a Purple box is in front, tap the Purple marbles from the center-right column one by one. They will clear without jamming the belt.
3. As you dig deeper, pale yellow marbles may appear. Do not drop them until a yellow box is visible in the active slots.
4. If the belt starts to fill with mixed colors, stop and only drop marbles that match the current front boxes.

Phase three: Finish the center and edges

1. Guide the Brown marbles from the middle-right into the Brown box that has now rotated forward.
2. Drop the dense blue multi-marble square from the bottom center into the Blue box when it is in front.
3. Clean up any leftover Pink, Light Blue, or Red from the upper corners. Always check the belt capacity; if only two slots remain, make sure your next tap clears at least three marbles.
4. Empty the remaining Pink marbles to finish the level.

Tips & tricks

• Always read the bottom row before making a move; the boxes dictate your safe colors.
• Keep the Conveyor Belt as empty as possible; space is your main resource.
• If you must drop a non-matching marble, ensure it won't block the belt for more than a few seconds.

Common mistakes

• Unlocking the center too early and dropping Purple before a Purple box is in front.
• Ignoring the lock counters and trying to clear the middle columns prematurely.
• Not waiting for the right box to rotate before dropping a color, causing a belt jam.
