Marble Sort Level 738 — Walkthrough and Solution

Marble Sort Level 738 presents a full board with a large numbered Panel in the upper right corner. That Panel will not open until you have completed eight bottom-row clears. The key is to ignore the tempting front-row colors and focus only on those that match your starting Boxes.

The Top Tray shows a front line of seven distinct colors: Light Blue on the far left, then Brown, White, Light Green, Pink, Yellow, and Red on the far right. Directly behind that row sits a solid line of Mystery Boxes, hiding the colors you need. Behind the Mystery Boxes, a third row reveals Orange, Purple, Yellow, Purple, Red, Dark Green, and Dark Blue from left to right. The Panel occupies the back right corner. Your bottom Boxes at the start ask for Dark Green, Light Green, and two Yellows. The second row of bottom Boxes is entirely Orange, indicating that Orange will become critical later.

Marble Sort Level 738 Walkthrough

Your opening moves must be precise. The bottom Boxes initially require Dark Green, Light Green, and two Yellows. Light Green and Yellow are available in the front row, so you can clear those immediately. However, Dark Green is not visible up front; it is buried three rows deep on the right side. To clear that first Dark Green Box, you will need to pull from the Mystery Boxes. The trap is that many front-row colors—Light Blue, Brown, White, Pink, and Red—have no matching Boxes at the start, so tapping them will only clutter your Conveyor Belt.

The imbalance here is that you must dig for Orange and Dark Green while avoiding the decoy colors. The Orange row in the bottom Boxes will eventually move to the active row, and you need to feed it continuously to tick down the Panel. The midgame will then shift to Purple, White, Light Blue, and Yellow demands, so you must manage your belt space carefully to avoid choking.

How to Beat Marble Sort Level 738 — Step-by-Step

Phase one: Secure the first clears

1. Tap the Light Green block in the middle-left of the front row and drop it into the matching bottom Box.
2. Tap the Yellow block on the middle-right and send it to its Box.
3. Now tap the two Mystery Boxes that were just uncovered behind those cleared blocks.
4. If a Mystery Box reveals Dark Green, use it to clear the leftmost starting Box immediately. If it reveals Orange, set it aside on the Conveyor Belt and keep digging.

Phase two: Feed the Orange row

1. Once the Orange bottom row moves up, start mining the left side. Carefully remove the Light Blue block from the far left to expose the Mystery Box behind it.
2. Tap that Mystery Box, then the visible Orange block in the third row on the far left.
3. Route those Orange marbles into the active Orange Boxes, watching the Panel counter drop from 8 to 7, then 6, then 5.
4. Continue sending every Orange you find to the bottom, clearing the row as fast as possible.

Phase three: Survive the midgame shift

1. When the Panel counter reaches 3, the bottom Boxes will change to demand Purple, White, Light Blue, and more Yellow.
2. Look for the visible Purple block under the edge of the Panel and another on the left side; guide them into the active Purple Box.
3. If your Conveyor Belt is clogged with White, Dark Blue, or Pink from earlier, do not panic. Wait for those colors to become active and then flush them out.
4. Keep clearing matches to reach the eighth clear and lift the Panel.

Tips & tricks

• Always prioritize clearing the bottom Boxes that match the front-row colors you can safely tap.
• Use the Conveyor Belt as a temporary holding area, but never let it fill completely—leave at least two empty spaces.
• When the Panel lifts, immediately process the hidden drop and clear any backlog of Light Blue, White, or Dark Blue marbles.

Common mistakes

• Tapping Light Blue, Brown, White, Pink, or Red at the start, which floods your belt with unusable colors.
• Ignoring the Orange row until it moves up, causing a shortage of Orange when you need it most.
• Letting the Conveyor Belt jam with too many colors, leaving no room to tap new blocks.
