Marble Sort Level 457 — Walkthrough and Solution

Marble Sort Level 457 is a tricky arrow-box maze that requires careful sequencing to avoid jamming the conveyor. The key is to ignore the red boxes initially and focus on clearing the light blue box first, which reveals a blue box behind it. Then clear the blue and white boxes, and finally use the multi-colored marbles to fill the red boxes.

The board features three arrow boxes: a pink one at the top with a down arrow, a left white arrow box pointing right, and a right white arrow box pointing left. The bottom row has light blue, red, white, and red boxes. The top tray contains various marbles, including light blue, blue, white, yellow, lime green, and multi-colored (red/yellow/green) stacks.

Marble Sort Level 457 Walkthrough

At the start, you have light blue, red, white, and another red box at the bottom. The red boxes are a trap because no red marbles are initially accessible. Your first goal is to clear the light blue box using the free light blue marbles in the top tray. Once that box is gone, a blue box appears behind it.

The critical insight is to avoid tapping the pink arrow until the end, as it releases a mix of blue, purple, and multi-colored marbles that will clog the belt. Also, avoid the left white arrow box early, as it holds the multi-colored marbles needed for the red boxes later.

How to Beat Marble Sort Level 457 — Step-by-Step

Phase one: Clear the light blue and blue boxes

1. Locate the light blue marble in the top right stack, but first clear any lime green marble above it by sending it to an open box or the belt.
2. Release the light blue marble and guide it to the light blue box on the far left of the bottom row.
3. Continue sending all accessible light blue marbles to fill that box until it drops away, revealing a mystery box that contains a blue box.
4. Now, find the blue marble in the top-left corner and send it to the newly revealed blue box.
5. There are more blue marbles in the central column, but do not activate the pink down arrow yet; only use the freely accessible ones to fill the blue box completely.

Phase two: Unlock the right side and clear white, yellow, and green

1. With the light blue and blue boxes gone, target the white box in the bottom row.
2. Tap the white arrow box on the right (pointing left) to release the stack of white, yellow, and lime green marbles.
3. Work quickly to sort these marbles: send white marbles to the white box, yellow and lime green to any open boxes or hold them temporarily.
4. Once the white box fills and drops, it reveals a mystery box, likely containing a yellow or lime green box.
5. Use the released yellow and lime green marbles to fill these new boxes, clearing the conveyor significantly.

Phase three: Handle the red marbles and finish

1. Now that the right side is cleared, tap the left white arrow box (pointing right) to release the stack of multi-colored (red/yellow/green) marbles.
2. Immediately send these multi-colored marbles to the two red boxes at the bottom, as they can fill any open red, yellow, or green boxes.
3. If additional boxes are revealed behind the red boxes, continue filling them with the multi-colored marbles.
4. Once the side stacks are gone, tap the pink arrow box at the top to release the final few marbles from the central column.
5. Sort these remaining marbles into the last open boxes to complete the level.

Tips & tricks

• Always have an open box ready before tapping an arrow box, or the conveyor will jam.
• Prioritize clearing the light blue box first because it unlocks the blue box, which is essential for progression.
• When the right arrow box is tapped, quickly send white marbles to the white box before the belt fills with yellow and green.
• Use the multi-colored marbles from the left arrow box efficiently to fill multiple red boxes at once.
• Save the pink arrow for last, as it releases a mixed batch that can be managed only when most boxes are cleared.

Common mistakes

• Tapping the pink arrow too early, flooding the belt with blue and purple marbles that have no destination.
• Attempting to clear the red boxes first, which is impossible and wastes moves.
• Activating the left arrow box before clearing the right side, causing a backlog of marbles.
• Ignoring the lime green marbles above the light blue stack, blocking access to light blue.
