Marble Sort Level 644 presents a board that looks easy but hides a trap: three numbered Panels, each requiring three clears, guard the back half, while two 2x2 Connected Boxes sit in the center, ready to dump four marbles at once. The key is to clear the bottom Boxes in the correct order to unlock the Panels and manage the Conveyor Belt space.

The Top Tray has a Panel at the top left, another at the top right, and a third in the middle, lower down. Tall candy cane-striped Tunnels wall off the left and right edges, with a shorter Tunnel under the middle Panel. In the center, two 2x2 Connected Boxes: the left one contains White, Dark Blue, and two Yellows; the right one has Green, Pink, Orange, and another Green. The bottom Boxes currently demand Orange, Pink, Red, and Green, in that order from left to right.

Marble Sort Level 644 Walkthrough

The bottom row of active Boxes, left to right, asks for Orange, Pink, Red, and Green. Behind the first Orange sits a Red, then a Pink; behind the first Pink are two Greens. This strict order means you can only pull colors that immediately feed these slots, or the Conveyor Belt will fill with unusable marbles.

The main trap is the left 2x2 Connected Box: it contains White, Blue, and Yellows, but the current bottom Boxes don't accept those colors. Triggering it early will drop four marbles you cannot clear, jamming the belt and blocking progress.

How to Beat Marble Sort Level 644 — Step-by-Step

Phase one: Clear the front line

  1. Tap the exposed Orange marble at the bottom of the Top Tray to feed the first bottom Box.
  2. Tap the exposed Green marble just right of that Orange to fill the fourth bottom Box.
  3. Tap the exposed Red marble above the bottom to satisfy the second Box.
  4. Tap the exposed Pink marble near the Red to clear the third Box.
  5. Do not touch the Connected Boxes; they are not safe until the bottom queue changes.
  6. Focus on clearing these three Boxes to reduce the Panel counters.

Phase two: Unlock the Panels and handle the left Connected Box

  1. After three clears, the Panels vanish, revealing Light Blue marbles under the top left and White marbles under the middle Panel. The bottom queue now rotates to Blue, Yellow, Purple, and Blue.
  2. Now trigger the left Connected Box; it drops White, Blue, and two Yellows.
  3. Route the Blue and Yellow marbles into their matching bottom Boxes.
  4. Let the White marble sit on the Conveyor Belt; it will match the White marbles from the middle Panel.
  5. Pull the Light Blue marbles from the top left Panel and send them down.
  6. Tap the candy cane Tunnels one at a time, checking each color against the current bottom demands. If a Tunnel drops an unwanted color, stop tapping them.
  7. As the center clears, expose Purple marbles and use them to clear the Purple bottom Box.

Phase three: Trigger the right Connected Box and finish

  1. When the bottom queue rotates back to Green and Pink, trigger the right 2x2 Connected Box, which releases Green, Pink, Orange, and Green.
  2. Guide the Green and Pink marbles into their matching bottom Boxes.
  3. Park the Orange marble on the belt if no slot is open; it will match later.
  4. Continue clearing the remaining marbles from the Tunnels and Panels, always following the bottom Box order.
  5. Keep the Conveyor Belt free of unmatched colors to avoid a jam.

Tips & tricks

  • Always prioritize the bottom Box demands; only tap a marble if it matches the first open slot.
  • Use the Tunnels sparingly: each tap costs a slot, and a wrong color can clog the belt.
  • When you see a 2x2 Connected Box, wait until the bottom queue includes its colors before tapping.
  • Keep an eye on the Panel counters; clearing three boxes is the gate to the midgame.

Common mistakes

  • Tapping the left Connected Box too early, which drops White, Blue, and Yellows with no matching bottom Boxes.
  • Rapidly tapping the Tunnels out of boredom, filling the belt with mismatched colors.
  • Ignoring the strict bottom Box order and pulling colors that don't feed the front row.
