Marble Sort Level 680 — Walkthrough and Solution

Level 680 is the giant vertical chain and left-side key trap. The central chain lock and the hidden key in the top-left corner create a narrow escape route, so focus all early moves on the left side.

Yellow → Purple. The Orange is the bait. Leave it until its box is ready.

Marble Sort Level 680 presents a board with a massive vertical chain in the middle of the Top Tray, locked by a large yellow lock, which prevents any play in the center. The upper half is covered with grey Hidden Boxes that obscure the path to a golden key stuck in the extreme top-left corner. This setup forces a disciplined approach: the right side is a distraction, and only a narrow left-side tunnel leads to victory.

The board's colors are Purple, Cyan, Orange, Light Green, Light Blue, Dark Green, Pink, Brown, and Red. The bottom receiving Boxes, from left to right, are Light Blue, Dark Green, Cyan, and Pink. The lowest accessible row of the Top Tray, from left to right, contains Orange, Purple, Purple, Cyan, Cyan, Light Green, and Brown. The key is to avoid Orange and Light Green early, as their receivers are buried, and instead focus on Cyan and Purple to open the left side.

Marble Sort Level 680 Walkthrough

The immediate bottleneck is the front row of bottom Boxes. Orange and Light Green are traps because their bottom Boxes are not accessible until later. The only safe match is Cyan, which clears the third-column receiver and reveals Purple behind it. After clearing Purple, Light Blue and Pink become available on the left side, allowing progress upward.

The imbalance is that the board's solution requires a vertical dig up the left column, ignoring the right side entirely. The right side's Hidden Boxes and blocks are decoys; clearing them wastes moves and clogs the Conveyor Belt. The center lock can only be broken by the key at the top-left, so all efforts must funnel there.

How to Beat Marble Sort Level 680 — Step-by-Step

Phase one: Clear the safe bottom receivers

  1. Tap the two Cyan marbles in the middle-right of the Top Tray to send them down. They fill the Cyan bottom Box in the third column, triggering its clear.
  2. Immediately route the two stacks of Purple on the left side into the newly opened Purple receiver, clearing it.
  3. Stop. Do not touch Orange or Light Green yet; they are deadly traps that will jam the belt.
  4. After Purple clears, Light Blue and Pink receivers appear on the left side. Drop the Light Blue marbles from the Top Tray to clear the front-left bottom Box.

Phase two: Dig the left tunnel

  1. Now the Light Green receiver under the first column is open. Feed the Light Green marbles from the Top Tray into it, which clears that receiver and strips the first layer of the Top Tray, exposing the bottom row of Hidden Boxes.
  2. Clear the Pink receiver by dropping Pink marbles from the left side, forcing more Hidden Box reveals.
  3. As Hidden Boxes pop, they throw random colors. If Dark Green appears, slide it into the second column's Dark Green receiver immediately.
  4. Maintain focus on the far-left column, ignoring the right side entirely, until the golden key is uncovered.

Phase three: Break the lock and finish

  1. Once the key is exposed, wait for its matching bottom Box to become available, possibly storing one or two off-colors on the belt temporarily.
  2. Drop the key to shatter the yellow lock and remove the chains, flooding the board with new marbles.
  3. Quickly clear the trapped Orange and Brown marbles that have been sitting safely in the right columns.
  4. Sort the remaining primary colors to finish the level, working front-to-back.

Tips & tricks

  • Always prioritize left-side clears over right-side opportunities; the right side is a distraction.
  • Keep the Conveyor Belt as empty as possible by avoiding Orange and Light Green until their receivers are open.
  • Use the Conveyor Belt as temporary storage only when absolutely necessary, and always clear it promptly.

Common mistakes

  • Dropping Orange early will clutter the belt and block progress, as its receiver is buried deep.
  • Clearing right-side Hidden Boxes wastes moves and can cause a jam before the left tunnel is complete.
  • Failing to clear Dark Green promptly when it appears can block needed slots.
