Marble Sort Level 157 — Walkthrough and Solution

Marble Sort Level 157 drops you into a board where the left side is sealed by a giant purple padlock, making the entire upper-left grid untouchable. Your only hope is to dig out a Yellow key box trapped on the right side of the upper waiting area, all while managing a Conveyor Belt that is already clogged with Red, Pink, and Light Green marbles. The key to beating this level is to prioritize clearing the front-row boxes that are safe—Brown, Light Green, White, and Dark Blue—so you can drop the Yellow key and unlock the vault before the Conveyor Belt overflows.

The layout is brutal: the Top Tray is overloaded with Light Green on the left and Brown on the right, with a pile of Red marbles sitting right in the middle like a trap. Your active bottom Boxes, left to right, are: Column 1 (Brown, Mystery, White, Green), Column 2 (Light Green, Brown, Light Green, Brown), Column 3 (Dark Blue, Light Green, Brown, Pink), and Column 4 (White, Mystery, Pink, Mystery). Above, the left side holds a Lock over Mystery Boxes, a Pink box, and a Red Arrow Box pointing up; the right side has the Yellow key box, with Brown, Red, and a Green Arrow Box beneath it; the middle has Green, a Light Blue Arrow Box, and Dark Blue at the bottom.

Marble Sort Level 157 Walkthrough

Your opening moves must clear the front row without touching Red. Start with the Light Green box in Column 2—feed it with Light Green from the Top Tray's left side. Then clear the Brown box in Column 1 using Brown from the right side of the Top Tray. Next, fill the White box in Column 4 using White marbles from the left-middle of the Top Tray. Finally, drop the Dark Blue box from the middle upper grid into Column 3 and fill it immediately.

The critical trap is that Red marbles are pure bait—if you drop any Red from the Top Tray before you have a Red box available, the Conveyor Belt will fill and end the game. You must avoid the middle of the Top Tray entirely until the Red box is released on the right side.

How to Beat Marble Sort Level 157 — Step-by-Step

Phase one: Clear the front row and unlock the path

1. Tap the Light Green box in Column 2 and fill it with Light Green marbles from the Top Tray's left side.
2. Tap the Brown box in Column 1 and feed it with Brown marbles from the Top Tray's right side.
3. Tap the White box in Column 4 and fill it using White marbles from the left-middle of the Top Tray.
4. Tap the Dark Blue box in Column 3 and fill it with Dark Blue from the middle upper grid's bottom box.

Phase two: Dig down the right side for the Yellow key

1. When the Brown box beneath the Yellow key drops into the active area, fill it immediately with Brown from the Top Tray's right side.
2. Wait for the Green Arrow Box to become active—do not tap it yet; it will point up and only work after the Red box above it clears.
3. Once the Red box drops into the active area, carefully release Red marbles from the Top Tray's middle and the Conveyor Belt to fill it, but only after the Brown box is done.
4. After the Red box is filled, the Yellow key box will drop—tap it and fill it with Yellow marbles from the Top Tray (you should have some). This breaks the padlock.

Phase three: Clear the Mystery cascade and finish

1. As soon as the lock breaks, the upper-left Mystery Boxes will start falling into your active columns. Tap each Mystery Box only when you see what color it demands, and match it from the Top Tray—do not blindly dump.
2. Clear the Red Arrow Box on the left and the Light Blue Arrow Box in the middle when they become accessible, using the arrows as guides for where to send marbles.
3. With the lock gone, the remaining Top Tray marbles will sort themselves into the Pink and Green boxes on the bottom right—finish by matching each color to its box.

Tips & tricks

• Always keep an eye on the Conveyor Belt—if it ever fills up, you lose instantly, so never drop Red until the Red box is in play.
• When Mystery Boxes appear, they are unpredictable—wait for them to show their color before you send any marbles from the Top Tray.
• Use the Arrow Boxes as hints: they point up, meaning you need to clear the box above them first, so prioritize those clearings.

Common mistakes

• Tapping Red marbles too early—this is the #1 cause of Conveyor Belt floods.
• Ignoring the Conveyor Belt pressure while digging for the key—you must balance moves to keep it from filling.
• Forgetting to fill the Yellow box immediately when it drops—delaying gives the Conveyor Belt time to overflow.
