Marble Sort Level 623 — Walkthrough and Solution

Marble Sort Level 623 is a grid-based puzzle where you must sort colored marbles into matching columns. The key is to prioritize Red, Dark Green, and Light Green first, while leaving Blue and Orange untouched until later.

The board has a 5x5 top tray with a fixed gray block in the center, splitting the play area into left and right sections. At the bottom, there are three protruding blocks: a White on the left, a Red in the middle, and a Blue on the right. Above these, directional arrows influence marble movement. The left side contains Dark Green, Light Green, and Blue marbles; the right side holds Purple, Orange, and Red. Four bottom columns are present, each with a stack of marbles waiting to be filled.

Starting from the left, the bottom columns demand: first column has Red on top, Red underneath, then Blue, and White at the bottom; second column has Red on top, Red underneath, Light Green, and Blue; third column has Dark Green on top, Light Green underneath, White, and Dark Green at the bottom; fourth column has Light Green on top, Dark Green underneath, Red, and Blue.

The trap: Blue and Orange marbles are plentiful in the top tray, but their corresponding bottom columns are buried deep, so releasing them early will clog your Conveyor Belt. Similarly, Purple marbles appear only after you clear some initial stacks.

How to Beat Marble Sort Level 623 — Step-by-Step

Phase one: Clear the safe colors

1. Start by releasing the Red block at the bottom center; it feeds into the Red columns on the left.
2. Do not touch the Blue block on the bottom right; leave it untouched.
3. From the left side of the top tray, drop Dark Green and Light Green marbles to clear the top of columns three and four.
4. After pulling those Greens, a Red block becomes accessible near the middle-right; send it down to finish the Red columns.
5. Continue using the arrows to guide any remaining Green and Red marbles down the left and right flanks, avoiding the Blue block.

Phase two: Release the hidden colors

1. Once the initial Red and Green columns are cleared, the bottom columns shift, and Purple and Orange columns appear.
2. Now you can safely drop the Orange and Purple marbles from the top tray; do this in clusters to avoid overloading the belt.
3. There is a Purple block with an upward arrow; ensure the path below it is clear before dropping it.
4. Monitor belt capacity; drop one color at a time and let it be absorbed before releasing the next.

Phase three: Finish with Blue and White

1. Now that the Blue columns are exposed at the bottom, you can finally release the Blue block you ignored earlier.
2. Clear the remaining White marbles from the top tray, as their columns are now accessible.
3. Collect any leftover Light Green and Blue marbles from the top corners, grouping them by color to prevent jams.

Tips & tricks

• Keep your Conveyor Belt as empty as possible; only drop marbles when you know their column is ready.
• Always check the bottom columns before releasing a color; if the matching column is not visible, wait.
• Use the directional arrows to your advantage; sometimes a marble needs to travel a longer path to reach its column.

Common mistakes

• Releasing Blue or Orange too early is the biggest mistake; it fills the belt and blocks progress.
• Dropping multiple colors in quick succession can cause a jam; always wait for the belt to clear.
• Ignoring the bottom column layout can lead to misjudging which colors are safe to drop.
