Marble Sort Level 663 Guide: The 9-Marble Cluster Blockade

Marble Sort Level 663 hits you with a massive spacing problem right from the starting line. Instead of a normal mix of single marbles, the bottom row of the Top Tray is plugged by three enormous 9-marble clusters. Red on the left, Purple in the middle, and Light Green on the right. These clusters act as heavy corks, trapping all the standard single marbles above them.

The dominant colors you need to juggle are Purple, Red, and Blue, but the game deliberately misaligns your lower Boxes to tempt you into a fatal mistake. You have to carefully manage how many marbles those giant clusters dump onto your Conveyor Belt. If you blindly tap the big groups just because they are at the bottom, your track will overflow instantly. Surviving this board requires precise timing and a strict order of operations.

The 9-Marble Cluster Pattern in Marble Sort Level 663

This specific board layout is built to punish impatience. You need to know exactly where the traps are before making your first move.

Look at the Top Tray. It features five columns. Columns one, three, and five are capped at the very bottom by the heavy 9-marble clusters (Red, Purple, and Light Green). Tucked behind those clusters in the vertical stacks are single marbles: Brown, Light Blue, and Blue in the lower section, followed by an agonizing horizontal row of glass-encased iced marbles right across the middle (Brown, Black, Dark Green, Yellow, Cyan). The top layers hold a chaotic mix of Pink, Orange, Yellow, and Blue.

Now check your bottom Boxes. The front row demands Blue, Purple, Dark Green, and Purple. The second row wants Cyan, Dark Green, Red, and Red. The third row holds Brown, Purple, Blue, and Green.

Here is the brutal trap in Marble Sort Level 663. The Red and Light Green clusters at the bottom of the Top Tray are absolute bait. You do not have a Red Box in the front row. You do not have a Light Green Box anywhere in the visible top four rows. Tapping either of those clusters will dump nine useless marbles straight onto your Conveyor Belt, instantly jamming it and ending your run. The entire board pivots on carefully using the center Purple cluster to open a safe working lane.

You have to carve out the center of the board first. Outer column plays will ruin your track space.

Opening Moves and Clearing the Purple Cluster in Marble Sort Level 663

Your very first taps dictate whether you pass or fail. Do not touch the left or right sides.

1. Tap the giant Purple 9-marble cluster located at the bottom center of the Top Tray.
2. Watch the math here. The two Purple Boxes sitting in your front row will absorb six of those marbles. This leaves exactly three Purple marbles sitting dead on your Conveyor Belt.
3. Accept the lost belt space for now. The center lane is now open, dropping a single Blue marble down to the bottom position.
4. Tap that single Blue marble. It will perfectly drop into the Blue Box sitting on the far left of your front line.
5. The front line will shift. Do not panic about the Dark Green Box that is still waiting.

Managing the Red Expansion in Marble Sort Level 663

With the center column partially hollowed out, the board shifts. The second row of Boxes will begin to slide forward, bringing two Red Boxes into active play.

1. Once the two Red Boxes reach the front row, immediately tap the giant Red 9-marble cluster on the bottom left of the Top Tray.
2. Just like the opening move, the twin Red Boxes will eat six marbles, leaving three stray Red marbles taking up valuable slots on your Conveyor Belt.
3. You now have a wide open left flank. Look at the single Brown and Orange marbles that just slid down. Leave them alone. You do not have an active Brown or Orange Box yet.
4. Shift your focus back to the center and the row of iced marbles. You must make matches near the ice to shatter the glass. Use the newly accessible Blue and Cyan marbles from the upper left to hit the remaining front-line Boxes.

Shattering the Ice and the Final Scramble in Marble Sort Level 663

Once the Red and Purple clusters are cleared, you have access to the deep upper rows. The biggest mid-game hurdle is the horizontal ice layer blocking the Dark Green, Yellow, and Black marbles.

1. Look for the Dark Green Box that has been stubbornly sitting on your board since the start. You must break the ice around the Dark Green marble in the center column to free it.
2. Pull down the loose Yellow marbles cascading from the top left (above the old Red cluster zone) to fill the incoming Yellow Boxes.
3. Keep completely ignoring the Light Green 9-marble cluster on the far right. Only tap it when a Light Green Box finally reveals itself from the hidden back rows.
4. Clear the scattered Black and Cyan marbles dropping from the shattered ice line. Always prioritize filling a Box completely over grabbing a single random color, as your Conveyor Belt will be dangerously tight from the leftover Red and Purple marbles until matching Boxes finally spawn to sweep them away. Stay focused on the active front row, and the board will easily collapse.
