Marble Sort Level 783 — Walkthrough and Solution

This board is a step-by-step unlock puzzle, not a simple color match. You must open the numbered bins in a precise sequence to reveal the Yellow marbles and finish safely.

The layout has a top tray with single-color stacks and a 3x3 grid, plus bottom columns that demand Brown, Dark Blue, Light Blue, Green, and Yellow. The top tray shows no Yellow initially, so you need to trigger bin unlocks to access it.

Marble Sort Level 783 Walkthrough

On the bottom, from left to right, the first column needs Brown, the second column is all Dark Blue, the third column requires Light Blue and Green, and the two rightmost columns are filled with Yellow. The top tray has single stacks of Dark Blue, Light Blue, Red, Pink, and Green on the left and right sides, while the center holds four numbered bins that contain Orange, Purple, and more.

The key trap is the Yellow columns: releasing any other color into them early will jam the belt. You must ignore them until the numbered bins unlock and start producing Yellow.

How to Beat Marble Sort Level 783 — Step-by-Step

Phase one: Open the first two bins

1. Tap the single Dark Blue tray on the left to drop a Dark Blue marble into the second column's Dark Blue boxes.
2. Use the single Light Blue and Green trays on the right to clear the third column's Light Blue and Green boxes.
3. Send one Dark Blue, one Light Blue, and one Pink marble (from the single trays) to satisfy the right bin labeled "1-1-1" and unlock it.
4. Continue clearing the Dark Blue and Light Blue boxes, sending two of each color, which unlocks the left bin labeled "2-2".
5. Do not touch the 3x3 grid yet, especially the Brown marble, as it has no matching box until later.

Phase two: Reach the central bins

1. Now clear outer marbles from the 3x3 grid that have matching boxes, like Green or Red, to expose the Orange and Purple marbles.
2. Drop the Orange and Purple marbles down to the belt and route them to their respective boxes.
3. Feed the central bins: the top one needs three Orange, three Pink, and three Dark Blue; the middle one needs two Orange, three Light Blue, and two Purple.
4. Once those bins are satisfied, they will release Yellow marbles into the bottom columns.
5. Now you can safely release the Brown marble from the grid and place it in the first column.

Phase three: Final cleanup

1. Focus on clearing the two rightmost Yellow columns using the newly available Yellow marbles.
2. Route any remaining colors to their boxes, ensuring you don't overload the belt.
3. Keep a steady flow: only tap a marble when you have a clear destination for it.

Tips & tricks

• Always prioritize unlocking the right "1-1-1" bin first, as it gives you more working space.
• Watch the belt length: if it fills, you lose, so release marbles only when you can immediately place them.
• Use the single-color trays to clear the bottom columns gradually, avoiding sudden rushes of color.

Common mistakes

• Releasing any color into the Yellow columns early will clog the belt—avoid that at all costs.
• Ignoring the numbered bins and trying to sort by color directly will leave you stuck with unmatchable marbles.
• Freeing the Brown marble from the 3x3 grid before its box is ready will jam the belt.
