Marble Sort Level 306 — Walkthrough and Solution

Marble Sort Level 306 drops you into a puzzle where a towering gray Mystery Box wall hides nearly the whole board. The winning order is clear from the start: clear both Blue boxes, then Orange, then the linked Pink-Brown pair, and only then trigger the arrows to break the wall. Early taps decide everything.

The top tray holds twenty-six gray Mystery Boxes stacked four deep, topped by two Gift Boxes stamped with “5”. Two Arrow Boxes guard the lower wall: one Orange pointing left, one Red pointing right. The bottom has four columns: far left is a Blue Box, middle-left Orange, middle-right another Blue, far right Green. Behind those, a set of Connected Boxes links Brown to Pink so they drop together. The Green Box on the far right is a decoy—no Green shows until the gifts open.

The bottom row demands, left to right, are Blue, Orange, Blue, Green. The connected Brown-Pink set sits in the second row, trapping progress until you fill both simultaneously.

The real trap is the linked pair: clearing one without the other is impossible, so you must park both colors on the belt at once. Also, the gray wall hides colors you can't predict, so never blind-drop.

How to Beat Marble Sort Level 306 — Step-by-Step

Phase one: Break the front line

1. Tap the first Blue set from the top tray and feed it into the far-left Blue Box.
2. Tap the second Blue set and route it into the middle-right Blue Box.
3. Now both Blue boxes clear, exposing the Brown-Pink Connected Boxes.
4. Drop the single visible Brown set onto the conveyor belt.
5. Send the single visible Pink set onto the belt as well; because the boxes are linked, both fill and vanish together.

Phase two: Trigger the arrows and chew the gray wall

1. With the linked pair gone, the Orange and Red Arrow Boxes become active.
2. Make sure you have an Orange bottom box open to receive the orange arrow, and a Red box ready for the red arrow.
3. Tap each arrow to pull the bottom row out from under the gray block, starting the Mystery Box cascade.
4. Let each Mystery Box fully reveal its color before you commit it to the belt—don't spam taps.
5. Match whatever colors appear, digging down vertically in the four columns to open a spare dumping column.

Phase three: Survive the Gift Box flood

1. Before opening the two Gift Boxes, check the conveyor belt: if more than two sets are parked there, clear them first.
2. Tap the match that pops both gifts, releasing ten new marble sets at once.
3. Sort the flood quickly, finally using the Green marbles to clear that stubborn far-right Green Box.
4. Always clear a box that reveals another underneath, and keep belt discipline until the last marble.

Tips & tricks

• Watch the belt capacity constantly—it's your lifeline, not a parking lot.
• When Mystery Boxes reveal colors, match them immediately if you have the bottom box open; otherwise, hold back.
• Use the empty column you create as an emergency buffer for unexpected colors.
• Keep the Green Box for last; it's not a priority until the gifts open.

Common mistakes

• Dropping unknown colors onto the belt before they're revealed jams the conveyor.
• Opening Gift Boxes with a full belt causes an instant game over.
• Forgetting that Brown and Pink are linked makes you waste moves and clog the board.
