Marble Sort Level 676 — Walkthrough and Solution

Marble Sort Level 676 uses a Top Tray with striped tubes on the left and a structured right side, plus four bottom Boxes. The second bottom column is sealed by a Lock until you find the Key. You need to clear the Pink wall, then the Reds, then unlock and finish with the Dark Blue blocks. The main priority is to feed the active Pink Boxes and never tap the front Purple cluster early.

On the Top Tray, the left half has three large candy-cane striped tubes with rainbow rims that release marbles in groups. The right half shows a front row of textured clusters: Purple on the near-left, Red in the middle, Pink on the near-right. Behind those, solid blocks of Dark Blue, Red, and Brown sit in a row. At the very back, three blue containers marked with a 3 hold reserved marbles. The bottom Boxes are in four columns: column 1 starts Pink, column 2 starts Dark Blue but is Locked, column 3 starts Pink, column 4 starts Pink. Column 2 cannot receive any marbles until you find the Key, which is hidden inside the striped tubes or solid blocks.

Marble Sort Level 676 Walkthrough

In the bottom sorting area, the left-to-right demands are: column 1 wants Pink, column 2 is Dark Blue but Locked, column 3 wants Pink, column 4 wants Pink. That means three active Pink Boxes at the start. You must fill all three to make the board shift forward. Once those are done, column 1 and column 4 will expose Red Boxes, column 3 will expose a Mystery Box, and column 2 remains Locked. The Mystery Box can ask for any color, so you need to be ready to pull from the left striped tubes or the right solid blocks.

The big trap is the textured Purple cluster on the front right of the Top Tray. It looks like an easy tap, but there is no active Purple Box on the bottom at the start. If you tap it, the Purple marbles will dump onto your Conveyor Belt and sit there, eating up space. You only have three usable drop columns until you unlock column 2, so any extra marble on the belt can cause a choke. The correct approach is to ignore Purple and focus on Pink first.

How to Beat Marble Sort Level 676 — Step-by-Step

Phase one: Clear the Pink frontline

1. Tap the textured Pink cluster on the bottom right of the Top Tray to send Pink marbles down to fill the open Boxes in columns 1, 3, and 4.
2. After that cluster runs out, tap the left striped tubes to dispense more Pink marbles until all three Pink Boxes are complete.
3. Do not touch the textured Purple or Red clusters on the right side yet.

Phase two: Handle the Mystery shift and find the Key

1. Once the Pink Boxes clear, watch the bottom row shift. Column 1 and column 4 now show Red Boxes, column 3 shows a Mystery Box, column 2 is still Locked.
2. Tap the textured Red cluster on the bottom right of the Top Tray to feed Red marbles into the active Red Boxes in columns 1 and 4.
3. If the Mystery Box in column 3 requests a color that is already exposed on the board (like Red or Pink), fill it immediately.
4. If the Mystery Box asks for a color that is behind the solid blocks on the right (like Brown or Green), pull those colors from the left striped tubes or from solid blocks after they shift forward.
5. Keep pulling from the left striped tubes while filling the Mystery Box and the Red Boxes, because the Key is hidden somewhere in those tubes or in the solid blocks. The moment the Key appears on the Conveyor Belt, it will automatically fly over to column 2 and break the Lock.

Phase three: Unlock column 2 and finish the level

1. Once the Lock is gone, the Dark Blue Box in column 2 becomes active. Tap the solid Dark Blue block in the middle row of the Top Tray's right side to fill that Box.
2. After that, another Dark Blue Box will appear behind it—fill that one too by tapping the same solid Dark Blue block again if it has more marbles, or pull from the striped tubes if needed.
3. Now start clearing the solid blocks of Brown, Green, and Orange from the right side of the Top Tray, matching them to the bottom Boxes as they step forward.
4. Keep an eye on the Conveyor Belt; even with four columns open, do not dump a color that has no active Box.
5. Finally, tap the three blue containers marked with a 3 at the back of the Top Tray to release their reserved marbles into the remaining bottom Boxes to finish the level.

Tips & tricks

• Always prioritize filling the active Pink Boxes first; do not let any other color go down until those are done.
• When the Mystery Box appears, check its color request against what is already on the board. If it matches a color you have, fill it immediately to keep column 3 moving.
• Use the left striped tubes as a reserve for any color that is not accessible on the right side; they are your only source for the Key.
• Keep the Conveyor Belt as empty as possible—never tap a cluster unless you have a matching active Box ready to receive it.
• Once column 2 is unlocked, fill the Dark Blue Boxes right away to avoid having two Dark Blue Boxes waiting later.

Common mistakes

• Tapping the textured Purple cluster at the start, which dumps Purple onto the belt with no open Box, causing a jam.
• Ignoring the Mystery Box and focusing only on the visible Red Boxes, which can stall column 3 and block the board.
• Using up all the marbles from the left striped tubes before finding the Key, leaving you stuck because you cannot unlock column 2.
• Dumping a color like Brown or Green too early before its matching Box has stepped forward, filling the belt with useless marbles.
