Marble Sort Level 304 — Walkthrough and Solution

Marble Sort Level 304 is a visual trap where the board's center is a fortress of obstacles. The key is to ignore the leftmost Yellow target at the start and methodically clear the accessible bottom row to break through the Hidden Boxes and thaw the Iced Boxes. Only then can you safely pop the Gift Box and manage the Tunnels.

The Top Tray is stacked with a bottom row of five accessible boxes: Brown on the far left, Purple, White in the middle, Pink, and another Brown on the far right. Above them sits a solid line of gray Hidden Boxes, and above that, five Iced Boxes lock away Blue, Red, Blue, Yellow, and Green. Two Tunnels on the left and right walls each hold three hidden boxes, and a Gift Box with a '4' sits dead center at the top. The lower active Boxes demand Yellow, Purple, Brown, and Pink from left to right.

Marble Sort Level 304 Walkthrough

The bottom Boxes from left to right require Yellow, Purple, Brown, and Pink. The first column wants Yellow, but no Yellow is available on the accessible bottom row—only the Iced Box holds it. This is the bait that clogs your belt if you rush.

The crucial imbalance: you must clear Purple, Pink, and Brown first to expose the Hidden Boxes, while saving the White for later. The Yellow target stays stalled until you thaw the center-right Iced Box.

How to Beat Marble Sort Level 304 — Step-by-Step

Phase one: Break the Hidden Wall

1. Tap the Purple box on the bottom row of the Top Tray; it matches the second lower Box and clears it.
2. Tap the Pink box on the bottom right; it drops into the far-right lower Box.
3. Tap either Brown box on the outer edges to fill the third lower Box.
4. Do not touch the White box yet—no active White target exists.
5. Check the Hidden Boxes that are now exposed; drop any that match the newly revealed lower Boxes (likely Blue and more Brown).

Phase two: Thaw the Ice and Pop the Gift Box

1. Clear boxes adjacent to the Iced Boxes to break the ice, prioritizing those next to the frozen Blue, Red, and Yellow.
2. Once the center-right Yellow Iced Box thaws, drop the Yellow marble immediately to finally satisfy the first lower Box.
3. Push up the middle, making four clears adjacent to the Gift Box—use the thawed Blue and Red marbles to tick down its counter.

Phase three: Survive the Tunnels and Finish

1. When the Gift Box bursts, pause and match only the colors needed for the current bottom Boxes—don't rapid-fire.
2. As you clear the sides, the Tunnels will dump three boxes each; ensure you have at least three open belt slots before the final clear in front of a tunnel.
3. When the lower Boxes cycle to White and Green, drop the saved White and collect Green from the Tunnels to clear the final targets.

Tips & tricks

• Always keep the Conveyor Belt as empty as possible; never drop a marble unless it matches an active target.
• Save the White box from the start—it becomes crucial later when a White target appears.
• Thaw the Iced Boxes systematically from left to right to avoid scrambling for space.
• Before triggering a Tunnel, count your open belt slots; three are needed to safely receive its contents.

Common mistakes

• Dropping the White early because you think it's safe—it wastes a slot and can block your belt.
• Chasing the Yellow target from the start, which leads to clogged slots and a lost game.
• Triggering a Tunnel without enough space, causing overflow and an instant fail.
