Marble Sort Level 329 presents a board dominated by a central Grey Cross of question mark boxes and two groups of Connected Boxes on the flanks. To succeed, you must prioritize clearing the active boxes early, ignore the tempting Red decoy, and time your releases from the Connected Box groups. The safe order is: clear Dark Green, Light Blue, and Purple first, then release the left cluster, then break the cross, and finally drop the right cluster when Orange and Green receivers appear.

At the start, the Top Tray's bottom row holds a Dark Green on the far left, a Red next to it, then a Light Blue, and two Purples on the right. The left side features a group of four Connected Boxes (Light Blue, Yellow, Orange, Brown) surrounded by a dashed border, while the right side has another group containing two Greens and two Oranges. The central Grey Cross blocks the upper rows, hiding many colors. The bottom receiver area begins with active boxes for Dark Green, Brown, Light Blue, and Purple. Behind these, the queues reveal: a stack of four Purples behind Dark Green, Light Green and Yellow behind Brown, and Orange and more Light Blue behind Light Blue. The lone Red in the top row is pure bait—no Red receiver is active or imminent, so it must be left untouched.

The initial bottom boxes demand Dark Green, Light Blue, and Purple, while Brown is trapped in the left Connected group. The first column is a Purple mine, the second column hides Light Green/Yellow, and the third has Orange/Light Blue. The central Grey Cross prevents access to the back rows until dismantled.

The biggest trap is the loose Red in the front row: dropping it early will clog the belt for half the game. The right Connected Boxes (2 Greens, 2 Oranges) are equally dangerous if released too soon, as they'll flood four belt slots before any Green or Orange receiver is active. Therefore, you must clear the safe colors, release the left cluster to get Brown, then methodically break the cross while feeding Purples to the left column, and only when Green and Orange receivers appear should you tap the right cluster.

How to Beat Marble Sort Level 329 — Step-by-Step

Phase one: Clear the safe openers

  1. Tap the loose Dark Green on the far left of the Top Tray's bottom row; it falls straight into the active Dark Green receiver.
  2. Next, slide the loose Light Blue positioned in the middle of that row; it matches the active Light Blue box.
  3. Then, release the first loose Purple on the right side; it fills the active Purple receiver.
  4. Leave the Red alone—do not touch it.
  5. Now that the belt is empty and Brown is still needed, tap the left Connected Boxes group. This drops Light Blue, Yellow, Orange, and Brown simultaneously. The Brown instantly sorts, and the Light Blue may also find a home, leaving only Yellow and Orange on the belt.

Phase two: Break the Grey Cross

  1. After clearing Brown, the second column shifts up, revealing a Yellow receiver. The Yellow on your belt will auto-sort, freeing space.
  2. Begin tapping the lowest boxes of the Grey Cross to reveal hidden colors. Prioritize feeding the first column, which is a stack of Purples—every time a Purple appears in the cross, drop it to keep that side moving.
  3. Do not tap the right Connected Boxes yet! Wait until the bottom receivers shift to include active Light Green and Orange.
  4. Continue clearing the cross, matching any revealed colors that have active receivers. Keep the belt clear by not dropping random colors.

Phase three: Release the right cluster and finish

  1. Once active Light Green and Orange receivers are visible, tap the right Connected Boxes to send down two Greens and two Oranges. They should sort immediately.
  2. Now, with the cross gone, the back rows reveal a mix of Red, Brown, Dark Blue, Pink, and White. At this point, a Red receiver should have cycled in, so it is safe to drop the Red you saved earlier.
  3. Keep matching front to back: only drop Dark Blue or Pink when you confirm the corresponding receiver is active. Ride out the final clears with a clean belt to finish the board.

Tips & tricks

  • Always keep the Conveyor Belt as empty as possible before triggering any Connected Boxes, as they drop multiple blocks at once.
  • When breaking the Grey Cross, work from the bottom up, and don't reveal colors you can't immediately sort.
  • Think of the first column as a Purple pipeline: feed it constantly to shift the board and reveal new receivers.

Common mistakes

  • Tapping the right Connected Boxes too early, which floods the belt with Greens and Oranges before they can be sorted.
  • Dropping the Red bait at the start, causing it to occupy a vital belt slot for many turns.
