Marble Sort Level 620 — Walkthrough and Solution

Level 620 is the crate and padlock trap. The central lock and crate setup looks daunting, but the real danger is the unreachable Light Blue in the middle—so focus on the outer columns first.

Red → Green. The Light Blue is the bait. Leave it until its box is ready.

This board type is a Lock-and-Crate puzzle. The key to beating Marble Sort Level 620 is to ignore the locked middle and clear the outer boxes in a specific order to break the obstacles and open the board.

The Top Tray has a free bottom row: on the left side sit Pink, Orange, and Yellow; on the right side sit Purple, Light Green, and Red. The center is a blank gap. Above, a padlock chain holds several columns, and two wooden Crates sit on the left and right. The top corners are blocked by Lock-and-Key blocks. The lower area has three rows of target Boxes, with the front row demanding Red, Light Blue, Yellow, and Light Green. Behind that row, the next row asks for Pink, Light Green, Purple, and White. Below that, a row of Mystery Boxes appears later.

Marble Sort Level 620 Walkthrough

The front row of bottom Boxes, from left to right, needs Red, Light Blue, Yellow, and Light Green. The next row behind it, from left to right, wants Pink, Light Green, Purple, and White. The only reachable colors at the start are Red, Light Green, Yellow, Pink, Orange, Purple, and some Light Blue in the center is locked. The trap is that Light Blue appears in the front row, but the only Light Blue marbles are locked in the center behind the chain, so you cannot fill that Box until you break the crates.

How to Beat Marble Sort Level 620 — Step-by-Step

Phase one: Clear the Front Corners

  1. Slide the Red marble from the far right of the Top Tray's bottom row into the leftmost bottom Box that asks for Red.
  2. Guide the Light Green marble from the right side into the far-right bottom Box that needs Light Green.
  3. Drop the Yellow marble from the left side into the third bottom Box from the left, which asks for Yellow.
  4. Park the Orange marble for a moment; there is no Orange bottom Box yet.
  5. After Red, Yellow, and Light Green are placed, the second row of bottom Boxes becomes accessible. Deliver the Pink marble from the left side into the leftmost Box of that second row.
  6. Route the Purple marble from the right side into the rightmost Box of that second row.
  7. Finally, feed the Orange marble onto the Conveyor Belt to satisfy the quota.

Phase two: Break the Crates and Open the Center

  1. Once Pink, Orange, and Yellow are cleared from the left side, the left Crate shatters, revealing four hidden boxes.
  2. Similarly, clearing Purple, Light Green, and Red on the right side breaks the right Crate.
  3. With the Crates gone, the center columns are exposed. Move the Light Blue marbles from the middle into the front Light Blue Box that has been waiting.
  4. As you drop the center marbles, the padlock chain dissolves, freeing the remaining columns.
  5. Watch the lower section: the third row of Boxes now pulls forward, showing a Mystery Box. Since your Conveyor Belt only has the single Orange marble, you have room to react to the Mystery Box's demand.
  6. Clear the newly exposed White and Light Blue marbles to fill any remaining visible targets.

Phase three: Unlock the Multiplier Gates

  1. Now the top corner Lock-and-Key blocks are reachable. Send the newly available Orange and Yellow marbles to unlock them.
  2. After unlocking, the pathways to the x2 Multiplier Gates open.
  3. Be precise when dropping through the x2 zones: if a Box needs three marbles and you send six, the extras will spill onto the Conveyor Belt.
  4. Reveal the final row of Mystery Boxes. Feed each target exactly what it asks for, keeping the belt empty to handle any overflow from the doubled drops.
  5. Clear all remaining marbles to finish the level.

Tips & tricks

  • Always clear the outer columns before touching the center; this prevents the Conveyor Belt from jamming.
  • Use the Conveyor Belt as a buffer: drop extra marbles only when you have space to recover.
  • When using Multiplier Gates, double-check the required count; sending too many marbles will cause a mess.

Common mistakes

  • Attempting to reach the Light Blue early wastes moves and clogs the belt.
  • Overfilling the Conveyor Belt with unneeded colors forces you to discard them, losing progress.
  • Misjudging the Multiplier Gates can overflow your Boxes and spill marbles, undoing your work.

Marble Sort Level 620 FAQ

Do I need boosters to beat Marble Sort Level 620?

No, boosters are not required if you follow the correct order, but a color bomb can help if you accidentally jam the belt.
