Marble Sort Level 804 is a bottleneck board where three wooden Crates split the Top Tray into four narrow columns, forcing you to work in tight vertical lanes. The center is blocked by two purple Locks and one yellow Lock above a cluster of three Iced Boxes, and the bottom row has a mix of solid and Mystery Boxes. To win, you must ignore the side columns and focus entirely on freeing the Iced Boxes to collect the purple and yellow keys, which unlock the rest of the board.
From left to right, the bottom Boxes demand Teal/Blue, Purple/Red, Light Green/Teal, Blue/Mystery, and Pink/Red/Orange. The far-left column holds Blue, Pink, and Teal stacked; the center-left has Green and Teal; the center-right has Pink and Purple; the far-right has Light Blue, Red, Pink, and Blue. The two Mystery Boxes hide in the second and fourth columns, and the top Iced Box contains a purple key, while the one below holds a yellow key.
Marble Sort Level 804 Walkthrough
Start by clearing the bottom row of textured marbles: send Orange, Red, Teal, and Blue down to their matching Boxes. This opens space without risk. Then target the marbles next to the Iced Boxes—clear the Red to the right of the top Iced Box, then the Green to its left, followed by the Light Green below it. Finally, drop the Purple under the purple Lock. These moves thaw all three Iced Boxes.
The biggest trap is the temptation to clear the outer columns early. Dropping that Blue from the top left looks easy, but its Box is buried under another, and you’ll clog the belt. Another imbalance: the center-right column has a Pink that can only be cleared after the yellow key, so don’t touch it until then. Also, the Mystery Boxes in the second and fourth columns stay hidden until you clear their covering Boxes, so plan around them.
