Marble Sort Level 766 — Walkthrough and Solution

Marble Sort Level 766 is a resource-management puzzle where the board is a Top Tray with six columns of marbles, a Conveyor Belt underneath, and five deep Box stacks below. The key is the x2 Multiplier Gate in the middle of the tray, which doubles any marble that falls through it. You must feed it Yellow and Red marbles to create enough to fill the demanding Boxes, but sending the wrong color will jam the belt.

The tray holds a mix of standard and dimpled marbles: Yellow, Red, Green, Purple, Pink, Dark Green, Orange, and Blue. The Boxes demand Yellow, Pink, Purple, Dark Green, and Red in huge quantities. The layout features two vertical blockers and one horizontal blocker, creating zones. The second column from the left has two Purple marbles trapping a crucial Yellow marble. Above the gate sits a lone Green marble. The far-left and far-right Box columns both start with Yellow Boxes, signaling the high demand for that color.

The five Box stacks, from left to right: the first column starts with Yellow on top, Red below it, then Yellow again, and Dimpled Red at the bottom. The second column has Pink on top, Purple underneath, then Pink, and Dimpled Yellow. The third column begins with Purple, then Dark Green, followed by Purple, and Dimpled Dark Green. The fourth column starts with Dark Green, then Yellow, then Dark Green, and Dimpled Pink. The fifth column starts with Yellow, then Pink, then Yellow, and Dimpled Purple.

The main imbalance is that you start with only three Yellow and three Red marbles, but you need at least six of each to fill the Boxes. The only way to get more is to use the x2 Gate. However, the gate also sits above a Green marble that, if sent through, creates two Green marbles with no Box to fill, clogging the belt. So you must carefully clear a path for Yellow and Red only.

How to Beat Marble Sort Level 766 — Step-by-Step

Phase one: Double the Yellows

1. Tap the two Purple marbles in the second column from the left; they fall into the third column's Purple Box, which now has two of three needed.
2. Release the trapped Yellow marble that was behind them.
3. Tap the single Green marble directly above the x2 Gate; it lands on the belt with no matching Box, but this clears the path.
4. Guide the freed Yellow marble through the x2 Gate, producing two Yellow marbles on the belt.
5. Route both Yellows to the far-left Box, which now has two of three.
6. Release the single Yellow marble from the first column and send it to the far-left Box, completing it and revealing a Red Box below.

Phase two: Double the Reds and clear the top layer

1. Send the lone Green marble from the belt to the fourth column's Dark Green Box, which now has one of three.
2. Release the Pink marble from the left side of the tray and drop it into the second column's Pink Box, filling it to two of three.
3. Release the Dark Green marble from the center-right and feed it to the fourth column's Dark Green Box, which now has two of three.
4. Clear a path for a Red marble to reach the gate; the Red marble in the top-right is accessible.
5. Release that Red marble and slide it through the x2 Gate, creating two Red marbles on the belt.
6. Direct both Reds to the far-left column's Red Box, which now has two of three.
7. Release another single Red marble from the tray and send it to the same Red Box, completing it and revealing a Yellow Box below.
8. Continue this pattern: double the Yellow again by sending a Yellow marble through the gate, then use those two Yellows plus one more to clear the far-right column's top Yellow Box.
9. Clear the remaining top-layer Boxes: complete the second column's Pink Box with a third Pink, the third column's Purple Box with a third Purple, and the fourth column's Dark Green Box with a third Dark Green.

Phase three: Clean up the lower stacks

1. With the top layer gone, the lower Boxes are exposed: the far-left has a second Yellow and a Dimpled Red, the second column has a Purple and a Dimpled Yellow, the third has a Purple and a Dimpled Dark Green, the fourth has a Yellow and a Dimpled Pink, and the fifth has a Pink and a Dimpled Purple.
2. Release the remaining dimpled marbles from the bottom of the tray, matching each to its corresponding Box column.
3. Work systematically: for each color, find a clear path from the tray to its Box, and drop it before releasing another.
4. Keep the belt clear; if it gets too full, pause and prioritize emptying the oldest marbles.
5. Finish by filling the last few Boxes one by one, ensuring no marble is left on the belt at the end.

Tips & tricks

• Always use the x2 Gate on Yellow or Red only; never on Green, Purple, Pink, or Dark Green, as those have no immediate need for doubling.
• Clear a path to the gate before releasing any marble that must pass through it, to avoid blocking the route.
• When the belt gets crowded, prioritize sending marbles to their matching Boxes rather than releasing new ones.

Common mistakes

• Sending a Green marble through the x2 Gate early on, which fills the belt with two useless Greens and blocks progress.
• Releasing Orange or Blue marbles at the top of the tray, as they have no Boxes available and will circle endlessly.
• Forgetting to complete a Box before moving on, leaving partial sets that clog the belt.
