Marble Sort Level 374 is a two-panel trap with a conveyor belt that clogs easily. You must clear 16 lower boxes to lift the plates, and the visible board lacks enough matching colors for your starting boxes. The solution is to feed the front rows with careful pulls from the hidden top-left quadrant, then use the panel-drop moment to flush your belt.

The top tray splits into four zones. The top-right and bottom-left quadrants are sealed by metal plates showing '16'. The bottom-right quadrant holds visible marbles: Red, Brown, Yellow on the top row; Light Green, a purple '2' box, Light Blue on the middle row; Brown, Bright Green, Dark Blue on the bottom row. The top-left quadrant is all hidden boxes with a central '4' box. Your initial bottom boxes demand Light Blue, Red, Bright Green, and Brown from left to right.

Marble Sort Level 374 Walkthrough

Your starting lower boxes, reading left to right, need Light Blue, Red, Bright Green, and Brown. The exposed bottom-right quadrant offers only one of each of those colors, so you cannot fill any box completely from the open board alone. The Yellow and Dark Blue marbles visible there are traps—they have no matching bottom boxes early on, so tapping them wastes belt space.

The imbalance is that you must source extra Light Blue, Red, Bright Green, and Brown from the hidden top-left quadrant, all while the 16-count panels lock away most of the board.

How to Beat Marble Sort Level 374 — Step-by-Step

Phase one: Feed the first row

  1. Tap the exposed Red from the bottom-right quadrant and guide it to the second bottom box.
  2. Drop the visible Brown into the fourth bottom box.
  3. Slide the Light Blue from the middle row into the first bottom box.
  4. Route the Bright Green from the bottom row into the third bottom box.
  5. Leave the Yellow and Dark Blue untouched.
  6. Now tap the hidden boxes in the top-left quadrant one by one. When a hidden box reveals a Light Blue, Red, Bright Green, or Brown, send it to the matching bottom box.
  7. If a hidden box shows a different color, let it sit on the conveyor belt and keep hunting for the four target colors until the first row of bottom boxes clears.

Phase two: Grind to 12

  1. After the first row clears, the panels' counter drops to 12, and a new set of bottom boxes appears. From left to right, they need Light Green, Dark Blue, Light Blue, and Red.
  2. Tap the visible Light Green from the bottom-right quadrant and feed it to the first box.
  3. Send the Dark Blue from the bottom row to the second box.
  4. Now the purple '2' and '4' boxes become active. As you clear marbles adjacent to them, these numbered boxes will unlock and drop, opening more space in their quadrants.
  5. Keep pulling from the remaining hidden boxes, but watch your conveyor belt. Pink and Yellow marbles may accumulate. Clear the active Light Green and Dark Blue boxes quickly to prevent a jam.
  6. When the second layer clears, the next bottom boxes are Pink, Brown, Yellow, and Pink. Use this opportunity to flush the Pink and Yellow off your belt by feeding them to these boxes.

Phase three: Drop the panels and reset

  1. Continue clearing the third layer of bottom boxes to drive the counter down.
  2. On the 16th clear, both panels vanish at once, revealing 18 new squares.
  3. Stop tapping immediately. Survey the full board, including the newly exposed marbles.
  4. First, clear any colors stuck on your conveyor belt using the newly revealed marbles. Empty your belt before touching the deep lower queue, which has heavily stacked Light Green and Bright Green boxes at the back.
  5. Once your belt is clear, the remaining board can be sorted without further trouble.

Tips & tricks

  • Always keep an eye on the conveyor belt's empty slots; never let it fill completely.
  • When a hidden box reveals an unwanted color, resist the urge to tap it again—let it sit until you have a matching box open.
  • Use the panel-drop moment to reset your belt; it is the only time you get a fresh start.

Common mistakes

  • Tapping the Yellow or Dark Blue marbles early, which fills the belt with useless colors.
  • Clearing hidden boxes too quickly without checking what you need, leading to a clogged belt.
  • Forgetting to feed the newly revealed colors after the panels drop, causing a jam right at the end.

No, boosters are not required if you follow the step-by-step strategy and manage your conveyor belt carefully.
