Marble Sort Level 724 — Walkthrough and Solution

Marble Sort Level 724 presents a sorting puzzle where a large central barrier must be removed by clearing 37 lower containers. The key is to manage the conveyor belt strictly, avoid risky pulls from the top corners until absolutely necessary, and methodically work through the outer columns to reveal the center.

The board's top area holds colorful layered tunnels, with connected mystery boxes at the far left and right. The receiving area at the bottom starts with Yellow, Green, Yellow, and White in the front row, but hidden boxes lurk beneath, making later demands unpredictable. Dominant colors include Yellow, Green, Dark Blue, and Dark Red.

Marble Sort Level 724 Walkthrough

Initially, the bottom receiving boxes demand Yellow, Green, Yellow, and White from left to right. Only the two Yellow boxes are immediately reachable from the top tray's bottom corners.

The main trap is the connected mystery boxes at the top corners: pulling one forces its partner down too, dropping two unknown colors onto the belt simultaneously. This can quickly jam the conveyor if done at the wrong time.

How to Beat Marble Sort Level 724 — Step-by-Step

Phase one: Clear the initial Yellows

1. Tap the Yellow box located at the bottom-left of the top tray.
2. Tap the Yellow box located at the bottom-right of the top tray.
3. These two Yellows will fill the first and third receiving slots at the bottom, clearing them.
4. Observe the newly revealed hidden boxes in those columns.
5. If a revealed box shows Dark Blue, tap the Dark Blue box sitting at the bottom-left of the top tray.
6. If a revealed box shows Dark Red, tap the Dark Red box at the bottom-right of the top tray.
7. Do not touch the Green or White bottom boxes yet; they are not accessible without risking the mystery boxes.

Phase two: Feed the tunnels

1. Examine the exposed bottom layers of the layered tunnels.
2. When a tunnel's bottom color matches a current bottom demand, tap that tunnel to send the color down.
3. After each tunnel layer is sent, the next color in that tunnel drops down into view.
4. Keep feeding these tunnel colors into the bottom grid, prioritizing outer columns.
5. Maintain an empty conveyor belt whenever possible; only pull from the connected mystery boxes when the belt is completely clear.
6. If a mystery box pull reveals colors you cannot use immediately, stop touching the top section entirely to avoid belt crowding.
7. Continue cycling through tunnel layers and newly revealed hidden boxes, always focusing on the outer columns to reduce the 37-count panel.

Phase three: Handle the center reveal

1. Once the 37th bottom box is cleared, the central panel will break apart.
2. Pause and survey the nine new boxes that appear in the center grid.
3. These central boxes often contain the exact colors you have been missing, such as Green and White.
4. Clear the remaining bottom boxes using these newly accessible center marbles.
5. If your conveyor belt holds any junk from earlier mystery pulls, slot those into matching bottom slots first to clear them before they block critical matches.
6. Finish the level by clearing all remaining boxes.

Tips & tricks

• Always clear the two initial Yellow boxes first to reveal hidden demands and start the panel countdown.
• Keep the conveyor belt as empty as possible; a full belt means you cannot pull new marbles, stalling progress.
• Use the central panel reveal to your advantage: those nine boxes are often the key to finishing the level.

Common mistakes

• Pulling from the connected mystery boxes too early, which drops two unknown colors and jams the belt.
• Ignoring the hidden boxes beneath the front row, leading to unexpected color demands that you cannot meet.
• Failing to keep the conveyor belt clear, which blocks the delivery of needed colors.
