Marble Sort Level 778 presents a U-shaped Top Tray where the bottom row is sealed by five textured Crates. To succeed, you must first remove these Crates before attempting to sort any marbles into the Boxes below. The key is to focus solely on the Crates at the start, using the red marbles available to break the left and right seals, then the light green and blue ones from the board and Surprise Bags.

The board layout has the Crates arranged from left to right as Red, Light Green, Blue, Light Green, Red. Above them, several marbles are locked, including Orange, Green, Light Green, and White. Only the top row marbles, the central dispenser (which initially holds Purple then Red), and the two Surprise Bags are accessible initially. The bottom Boxes are waiting but must be ignored until the Crates are gone.

For the bottom Boxes, the leftmost column starts with a Red Box, the second column has a White Box, the third column has a White Box, the fourth column has a Yellow Box, and the rightmost column has a Blue Box. These become your targets after the Crate wall is removed.

A common trap is to start sending top-row marbles down to the Boxes early, which jams the Conveyor Belt with colors that cannot be used yet. The correct approach is to clear the Crates first, as they block the entire lower part of the Top Tray, preventing access to many marbles.

How to Beat Marble Sort Level 778 — Step-by-Step

Phase one: Clear the Red Crates

  1. Tap the red marble in the far-right column of the top row.
  2. Then tap the red marble in the second column from the left (adjacent to a green marble) to release it.
  3. Tap the central dispenser once to release a Purple marble (let it sit on the belt), then tap it again to release the Red marble that follows.
  4. Send all three Red marbles to the red Crates (the leftmost and rightmost Crates). They will each clear after receiving three marbles, freeing the marbles above them.

Phase two: Clear the Light Green and Blue Crates

  1. Now locate three Light Green marbles. One sits directly below the left Surprise Bag, another is in the middle row now accessible after the Red Crates cleared.
  2. Release the Light Green marble from under the Surprise Bag and the one from the middle row.
  3. Tap the left Surprise Bag repeatedly until a Light Green marble appears. Release it and send all three to the Light Green Crates (second and fourth from left) to clear them.
  4. For the central Blue Crate, there are no Blue marbles on the board initially. Tap the Surprise Bags until you collect three Blue marbles. This step is delicate because you may release unwanted colors; be patient and only release the Blue ones when they appear, then send them to the Blue Crate.

Phase three: Sort the Remaining Marbles

  1. With all Crates gone, the entire Top Tray is open. Now focus on clearing the bottom Boxes. The Conveyor Belt is likely cluttered, so start by clearing a column to create space.
  2. Look for easy matches. For example, the third column from left needs a White marble; you have one in the grid. The leftmost column needs a Red; use a freed Red marble.
  3. Work column by column, sending marbles to match the front Box of each column. Avoid sending multiple of the same color in a row; instead, alternate to keep the belt moving.
  4. Continue releasing marbles from the Top Tray and Surprise Bags as needed, matching them to the front-most Boxes until all Boxes are filled and cleared.

Tips & tricks

  • Always prioritize clearing the Crate wall before touching the Boxes; otherwise, you'll run out of space.
  • When tapping Surprise Bags for Blue marbles, do it slowly and stop as soon as you have three, to avoid filling the belt with other colors.
  • After the Crates are gone, clear the Boxes in a balanced way: send one marble to a column, then switch to another column to prevent jams.

Common mistakes

  • Sending top-row marbles to the Boxes prematurely, which floods the Conveyor Belt.
  • Releasing too many marbles from Surprise Bags while hunting for a specific color, causing a backlog.
  • Ignoring the need to clear entire columns; partial fills lead to deadlocks.
