Marble Sort Level 720 — Walkthrough and Solution

Marble Sort Level 720 presents a board where three glass domes with numbers (two showing 3, one showing 4) sit over the central columns, and two Mystery Boxes are hidden in the lower grid. The key is to clear the initial Pink and Purple boxes immediately, avoid the Yellow and Orange marbles that are exposed on the right side, and methodically break the domes before dealing with the surprises.

The layout has the bottom row of containers requiring Pink, Purple, Light Blue, and Green from left to right. The first column stacks Pink on top, then Light Green, then Orange, and hides a grey Mystery Box underneath. The second column has two Purple boxes stacked, then Green, then Yellow. The third column hides another Mystery Box under Light Blue, Dark Blue, and Pink layers. The top tray holds clusters of Pink on the left and center-right, Purple in the middle, and Yellow and Orange on the right, but those right-side colors are decoys because their matching bottom boxes are buried deep. The numbered domes block the middle area until their counters reach zero.

Marble Sort Level 720 Walkthrough

Start by focusing on the front row: the leftmost container needs Pink, the next needs Purple, then Light Blue, and Green. The containers in the second row are stacked, with the second column having two Purple boxes one above the other, then Green, and Yellow at the bottom. The third column hides a Mystery Box beneath Light Blue, Dark Blue, and Pink layers.

The main trap is the Yellow and Orange marbles sitting exposed in the top right. If you drop them early, they will clog your Conveyor Belt because their bottom boxes are not accessible until later. The numbered domes (two 3s and a 4) also block the central columns, so you must clear lower boxes to reduce their counters to zero and shatter them.

How to Beat Marble Sort Level 720 — Step-by-Step

Phase one: Clear the Front Row

1. Tap the exposed Pink marbles on the bottom left and middle right of the top tray to fill the first Pink Box in column one, clearing it.
2. Next, target the Purple blocks: you have two Purple boxes stacked in column two, so pick up the accessible Purple marbles near the center right and lower right to fill the first Purple box.
3. Do not touch the Yellow and Orange marbles on the right side; they are a trap.
4. Clear the Light Blue and Green front boxes using the exposed clusters on the left and right edges.
5. Watch the numbered glass domes: each time a bottom box clears, the counters drop. Keep clearing the accessible Light Green and Dark Blue boxes that drop down next until the domes with '3' reach zero and disappear.

Phase two: Handle the Mystery Boxes

1. After the domes break, the upper middle area opens up, revealing Dark Blue and Orange blocks.
2. Pause before tapping too many top tray marbles. When a Mystery Box reveals its color, check the board to see if that color is accessible or buried.
3. Start peeling back the top layered stacks: the top layer is Purple, so clear those Purple chunks to expose Green and Blue underneath.
4. Drop the Orange marbles from the newly opened center columns into the Orange Box that is now exposed in column one.
5. Manage your Conveyor Belt strictly. If a Mystery Box reveals Yellow, and you finally have access to the Yellow bottom box, now is the time to drop those Yellow marbles you ignored at the start.

Phase three: Break the Final Stacks

1. Focus on the left side wall: clear the hidden Red and White marbles that finally drop down.
2. Match the remaining layers from the top corner figures; you will find Light Blue and White chunks hidden in the final layers. Drop them only when their matching bottom box pushes to the front.
3. Clear the last remaining Mystery Box reveals one by one. Do not release a color from the top tray unless you are absolutely certain it finishes a three-marble clear. Keep the belt clean, let the final boxes drop, and finish the board.

Tips & tricks

• Always prioritize clearing the bottom row boxes that are currently accessible; this reduces dome counters and opens up space.
• Keep a mental note of which colors are buried under the top stacks; you may need to plan multi-step clears.
• When a Mystery Box reveals a color, check if its matching bottom box is available; if not, avoid dropping that color from the top tray.
• Use the Conveyor Belt as a buffer, but don't let it get full; if you have more than two marbles waiting, you are over-tapping.
• Break down the top layered stacks from the top down; never try to grab a lower color without clearing the layers above.

Common mistakes

• Tapping the Yellow and Orange marbles early because they are exposed but their boxes are buried, leading to a jammed belt.
• Ignoring the numbered domes and not clearing boxes in the right order, leaving the middle blocked and reducing your options.
• Releasing a color from the top tray without confirming its bottom box is accessible, especially after a Mystery Box reveals a new color.
