Marble Sort Level 750 — Walkthrough and Solution

Level 750 is clearing the double '4' hidden boxes. The real challenge in Marble Sort Level 750 is the pair of central Hidden Boxes that lock the board until you dig out the Red Box on the far left—so your opening plan must ignore all easy matches and focus solely on that left stack.

Marble Sort Level 750 is a deep puzzle with a top tray full of tempting colors and a set of bottom Boxes stacked four high. The key is to realize that the leftmost column holds the entire solution: it is stacked with Dark Blue, Orange, Light Blue, and finally Red at the very bottom. You must clear those three upper Boxes in that exact order to expose the Red Box, then fill it with red marbles. Only after that can you release the single red marble trapped between the two central Hidden Boxes, which will activate them and let you finish the level.

The board is arranged with the top tray split into several areas: on the upper left and right there are static blocks of marbles, and below them two rows of single marbles sit just above a Conveyor Belt. A rainbow-striped dispenser moves horizontally above the tray, introducing extra marbles over time. The bottom Boxes are arranged in several columns, each four marbles deep. The far-left column is the critical one: Dark Blue on top, Orange beneath it, Light Blue below that, and Red at the bottom. The two Hidden Boxes are situated in the center of the board, each marked with a '4', and they are initially gray and locked behind light barriers. Between them sits a single red marble that acts as the trigger for unlocking them. The rest of the board is filled with colors like Lime Green, Orange, and various blues, but those are a distraction—clearing them early will clog the Conveyor Belt with marbles you cannot use yet.

Marble Sort Level 750 Walkthrough

Your initial goal is to unbury the Red Box in the leftmost column. The three Boxes above it—Dark Blue, Orange, and Light Blue—must be cleared one by one, in that order. Keep the Conveyor Belt as empty as possible during this phase, because any extra marble can block the path for the colors you need.

The trap is that the board offers many easy matches on the right side, such as Lime Green and Orange, which are tempting to clear early. However, doing so will fill the Conveyor Belt with marbles that have no matching Box available yet, choking the pipeline and making it impossible to deliver the Dark Blue, Orange, and Light Blue marbles needed for the left column. You must ignore those easy matches and focus on the left side until the Red Box is exposed.

How to Beat Marble Sort Level 750 — Step-by-Step

Phase One: Clearing the Left Column

  1. Locate the Dark Blue Box at the top of the leftmost column. Find a Dark Blue marble in the lower textured row of the Top Tray and send it down. Repeat this three times to empty the Box.
  2. Next, the Orange Box is now revealed. Obtain Orange marbles from the top-left block (one is behind a Brown marble) and from the lower textured row. Route three Orange marbles to this Box to clear it.
  3. With the Orange Box gone, the Light Blue Box is accessible. The board provides Light Blue marbles in the top corner blocks and in the lower row of single marbles. Drop three Light Blue marbles to empty this Box, exposing the Red Box at the bottom.

Phase Two: Unlocking the Hidden Boxes

  1. Now that the Red Box is visible, collect Red marbles—one is in the top-left block, another in the lower single-marble row—and feed them to the Red Box until it is cleared.
  2. Clearing the Red Box releases the single red marble that was locked between the two Hidden Boxes. Tap that red marble immediately; it does not go to a Box but instead activates the Hidden Boxes.
  3. The Hidden Boxes will now light up and reveal that they require Light Blue marbles. Each has a '4' on it, meaning you need to deliver four Light Blue marbles to each. Prioritize this task: use the Light Blue marbles from the Top Tray and the rainbow dispenser to fill both Hidden Boxes completely.

Phase Three: Cleaning Up the Rest

  1. With the Hidden Boxes solved, the central lock is gone. Now you can safely clear the remaining Boxes on the right side of the board. Work from top to bottom, starting with Lime Green and Orange Boxes that are near the top.
  2. Keep an eye on the rainbow dispenser—it will be your main source of marbles now. Match the colors it offers to the topmost available Box.
  3. Continue sorting the leftover colors one by one. As long as you prevent the Conveyor Belt from jamming, you will complete Marble Sort Level 750 without trouble.

Tips & tricks

  • Always check the leftmost column first; if it is not yet clear, ignore all other matches.
  • Use the Conveyor Belt sparingly in the early phase—only send marbles that are immediately needed.
  • When the Hidden Boxes activate, drop everything else and fill them with Light Blue as fast as possible.

Common mistakes

  • Clearing easy matches on the right side early, which floods the Conveyor Belt with useless colors.
  • Tapping the central red marble before the Red Box is cleared—that marble stays locked until then.
  • Ignoring the Hidden Boxes after they activate, letting the Conveyor Belt fill with other colors.
