Marble Sort Level 677 — Walkthrough and Solution

Marble Sort Level 677 presents a Top Tray that is a layered stack of visible marbles, gray Mystery Boxes, and a row of Surprise Bags. The key to finishing is to clear the bottom Boxes in a precise order without ever letting the Conveyor Belt reach full capacity.

At the start, the bottom row of active Boxes demands Yellow, Lime Green, Red, and another Lime Green from left to right. The front line of the Top Tray shows Light Blue, Lime Green, Red, Dark Blue, Orange, Pinkish-Red, and White. Behind these lies a Mystery Box row, then a visible row with Dark Blue, White, Dark Red, Lime Green, Dark Green, Orange, and Purple. At the very back, five Surprise Bags wait in a row.

Marble Sort Level 677 Walkthrough

The opening bottom Boxes require Yellow, Lime Green, Pinkish-Red, and Lime Green. The front row of the Top Tray does not align with these needs, so you must be selective about what you drop first.

The main challenge is that the front row hides the Mystery Boxes, and those hide more colors. The Conveyor Belt fills quickly because you must store unmatched colors while you search for the exact matches the lower Boxes need.

How to Beat Marble Sort Level 677 — Step-by-Step

Phase one: Clearing the Front Row

1. Tap the Lime Green marble from the front row and guide it into the second bottom Box.
2. Slide the Pinkish-Red marble from the front row into the third bottom Box.
3. Do not touch the Light Blue or Dark Blue front marbles yet.
4. As the front row empties, the first Mystery Box row reveals its contents. If a Yellow appears, drop it into the far-left bottom Box.
5. When the visible row behind the Mystery Boxes becomes accessible, look for Dark Blue, White, Red, Green, Orange, and Purple. Only drop those that match the newly opened lower Boxes.
6. Store any unmatched colors on the Conveyor Belt, especially Blues and Whites. Keep the belt below 60% full to avoid a jam.

Phase two: Handling the Surprise Bags

1. After the visible row is gone, the five Surprise Bags become tappable. Each bag releases a random mix of marbles.
2. Open only the left-most Surprise Bag. Let its contents spill onto the belt.
3. Check the active bottom Boxes now. They likely need Dark Blue, Teal, Brown, or Purple. Feed the bag's marbles that match these colors immediately.
4. If the bag gives Teal or Purple, route them into the third and fourth bottom Boxes.
5. Drop the Dark Blue marble from the left side of the Top Tray into the second column's Box.
6. Empty the Conveyor Belt of all stray marbles before opening another Surprise Bag.
7. Repeat this process for each Surprise Bag, always one at a time, until all five are gone.

Phase three: Final Mystery Boxes

1. With the Surprise Bags cleared, the last row of Mystery Boxes at the top activates.
2. Reveal these Mystery Boxes slowly, one by one.
3. Drop any White, Orange, or Yellow marbles that appear to clear the matching lower Boxes.
4. Work through the final columns one at a time, feeding the exact colors required by the remaining Boxes.
5. Continue until all Boxes are full and the level ends.

Tips & tricks

• Always prioritize clearing the bottom Boxes that match the marbles you can access; don't just tap the front row randomly.
• Use the Conveyor Belt as temporary storage, but never let it fill completely; keep a few empty spaces for Surprise Bag spills.
• When opening Surprise Bags, do it in isolation—wait until the belt is mostly empty before tapping the next one.

Common mistakes

• Opening multiple Surprise Bags in quick succession, which floods the belt with random colors and causes a jam.
• Dumping the entire front row without checking if the colors match your bottom Boxes, leading to a full belt early.
• Ignoring the need to clear the belt before activating the next Surprise Bag, making it impossible to handle the random drops.
