Marble Sort Level 305 — Walkthrough and Solution

Marble Sort Level 305 is a puzzle that opens with a wall of grey Mystery Boxes and three numbered Gift Boxes in the center. You must trigger the Gift Boxes early to reveal the colors you need, especially Pink, which is completely hidden at the start. The initial visible colors include Red, Green, Purple, and Light Blue, but the bottom receivers require Red, Pink, Yellow, and Pink, creating an imbalance that forces you to dig.

The Top Tray is crowded with a Red box on the far left, then Green, Purple, Light Blue, and another Purple, with a blue box containing Yellow in the center. The bottom row demands Red on the far left, then Pink, Yellow, and Pink on the right. The grey Mystery Boxes and Gift Boxes obscure the Pink, Orange, and Dark Blue marbles that will appear after the reveal.

Marble Sort Level 305 Walkthrough

The front-left bottom Box requires Red, the second requires Pink, the third Yellow, and the fourth Pink. You have no Pink visible initially, so you cannot clear those receivers until you break open the Gift Boxes. The only safe first move is to send the Red box straight down to match the left receiver.

The trap is that the visible Green, Purple, and Light Blue marbles are not needed yet; they will clog your Conveyor Belt if you drop them prematurely. You must force the Gift Boxes to open by clearing the front-line boxes, which then reveals the hidden Pink and other colors.

How to Beat Marble Sort Level 305 — Step-by-Step

Phase one: Clearing the front line

1. Tap the Red box on the far left of the Top Tray and deliver it to the matching Red receiver on the bottom left.
2. Next, tap the Green box on the front line and stash it on the Conveyor Belt.
3. Then tap the Purple box adjacent to Green and send it to the belt as well.
4. After that, tap the Light Blue box on the right and put it on the belt.
5. Finally, tap the second Purple box and move it to the belt. These actions trigger the Gift Boxes, which burst open.

Phase two: Revealing and clearing Pink

1. After the reveal, locate the newly exposed Pink boxes on the left and right wings and drop them into the two Pink receivers in the bottom row.
2. Clearing those Pink receivers shifts the board, exposing Green and Purple lower Boxes that match the marbles you stashed earlier, so they automatically clear from the belt.
3. Now focus on the Yellow receiver in the third column. Find the Yellow box that was behind the blue stack or on the top right and feed it to the receiver.

Phase three: Final cleanup

1. With the front receivers gone, Light Blue and Red boxes appear in the lower rows. Pull down the Dark Blue boxes from the left wing to access the Light Blue beneath them.
2. Do not touch the Orange boxes on the sides until the Orange receiver cycles into position; otherwise, you'll jam the belt.
3. Feed the remaining Red and Green boxes from the right side to their receivers.
4. Finally, drop the remaining Yellow and Purple marbles from the top to complete the level.

Tips & tricks

• Always clear the front Red receiver first to create room for maneuvering.
• Use the Conveyor Belt as a temporary holding area, but keep it from filling up completely.
• After the Gift Boxes open, prioritize Pink to unlock the board's full potential.

Common mistakes

• Dropping Green or Purple too early can clog the belt and prevent you from reaching the Gift Boxes.
• Leaving the Pink receivers untouched will block the board from shifting and revealing essential lower boxes.
• Ignoring the Yellow receiver until the end can cause a bottleneck when you need to clear final marbles.
