Marble Sort Level 301 — Walkthrough and Solution

Marble Sort Level 301 is a vertical maze with two dark dividers that split the top tray into three narrow channels. The key to victory is ignoring the tempting Light Blue marbles on the far edges and instead focusing on the accessible Purple, Brown, and White marbles near the bottom. You must also carefully time the release of Iced and Connected Boxes to keep your Conveyor Belt from overflowing.

The bottom row of the top tray, from left to right, holds White, Purple, White, Red, and Brown. Directly below, the starting bottom Boxes demand Light Blue, Brown, Purple, and Light Blue. The Light Blue marbles in the top tray are buried high on the left and right edges, unreachable until late. Meanwhile, Purple and Brown marbles are easily accessible on the bottom edge, making them the correct first targets.

Marble Sort Level 301 Walkthrough

The bottom Boxes start with demands for Light Blue on the far left and far right, but those colors are locked high up. The center and right lanes hold the key: Purple and Brown are ready to drop, and clearing them will unlock the path to the Iced Boxes and eventually the Light Blue.

The trap is that the two outer Light Blue Boxes appear to be an easy double clear, but grabbing them early fills your Conveyor Belt with useless marbles, leaving no room for the Purple, Brown, and White that are crucial for cracking the ice and triggering the Connected Boxes later. You must resist the bait and prioritize the center colors first.

How to Beat Marble Sort Level 301 — Step-by-Step

Phase one: Hollow out the center

1. Tap the accessible Purple box (mid-left) to send its marbles into the center bottom Box that needs Purple.
2. Drop the Brown box on the far right edge into the bottom Brown Box.
3. Leave the Light Blue bottom Boxes untouched; do not tap any Light Blue marbles yet.
4. Clear the two White boxes on the bottom edge, feeding them into the White bottom Box that appears after the first Brown and Purple are filled.
5. Pull the Red box from the mid-right edge and guide it to an available slot.

Phase two: Thaw the Iced Boxes

1. After clearing the White boxes on the left, the Iced Box holding Purple will crack—drop it immediately to free up belt space.
2. On the right, dropping Red and Brown causes the Green Iced Box to thaw; release it to fill the new Green bottom Box on the far left.
3. Before tapping any Connected Boxes, ensure your Conveyor Belt has at least four empty slots.
4. Tap the linked Green and Orange boxes together—they will drop simultaneously, consuming multiple slots.
5. Now that the middle is open, finally tap the Light Blue boxes from the upper corners to satisfy the two waiting bottom Boxes.

Phase three: Final top tray clear

1. Drop the single Green box at the top peak to feed the active Green bottom Box.
2. Sweep the Pink and Orange side wings: Pink first, as the bottom Boxes prioritize it after Green.
3. Flush the last Connected Boxes at the top, keeping the belt clean to let the remaining colors slide into the back row and finish the level.

Tips & tricks

• Always check the bottom Box demands before each move to avoid filling a slot with a color that won't be needed soon.
• Count the empty slots on your Conveyor Belt before triggering any Connected Boxes—they can drop up to four marbles at once.
• If you accidentally tap a Light Blue early, restart quickly; it's almost impossible to recover from the jam.
• Use the vertical dividers to your advantage: they restrict what you can drop, so plan your moves around the accessible lanes.

Common mistakes

• Falling for the Light Blue bait at the start and filling the belt with those marbles, leaving no room for the Purple and Brown you actually need.
• Triggering Connected Boxes without checking belt space, causing an immediate overload and a forced restart.
• Ignoring the Iced Boxes until later, which blocks the upper lanes and prevents progress.
