Marble Sort Level 347 Guide: The Iced Box Blockade and Yellow Lock Trap

Stuck on Marble Sort Level 347? I don't blame you. This board looks straightforward for about five seconds before the bottom fills up and you realize half the top tray is completely locked down. The dominant colors here are Green, Red, and Yellow, but the real enemy is the physical layout holding them hostage.

Right away, you see those massive horizontal yellow locks pinning the left and right columns. You also have a central Tunnel marked with a '4' and a nasty row of Iced Boxes sitting right underneath it. The game loves to bait you into clicking whatever is free on the outer edges. Don't fall for it. If you touch the wrong exposed colors early, your run is dead.

The Yellow Lock Board Pattern in Marble Sort Level 347

Let's break down exactly what you are looking at. The Top Tray is heavily bottlenecked by a combination of physical barriers and blocked paths. Your immediate playable row is scattered. You have a White box on the far left, followed by a Green box. In the dead center, there is a low-hanging cluster consisting of Red, Green, and Yellow. Moving to the right, you have another Green box, ending with a Light Pink box on the far right edge.

Right above that center cluster sits the danger zone. You have three cracked Iced Boxes forming a literal wall across the middle of the board. The purple and white icy textures mean they are frozen shut. Until you drop the adjacent colored boxes touching them, they aren't going anywhere. Hovering dead center above the ice is a blue Tunnel that hides four boxes. You have no idea what colors are inside that Tunnel, which makes planning ahead incredibly stressful.

Now look at the top left and top right. Those vertical columns are stacked with Hidden Boxes marked with question marks. You absolutely cannot reach them right now. Two yellow horizontal pins act as a Lock and Key system, physically barring those columns. These locks are tied directly to the boxes supporting them underneath. You have to carve out the middle-left and middle-right of the board to pull the yellow pins out of the way.

Your starting lower Boxes dictate everything about your opening strategy. The Conveyor Belt gives you exactly one Red box on the far left and three Green boxes taking up the rest of the slots. This is a very specific setup. Orange, Brown, and Pink marbles are sitting completely exposed in the second row of the Top Tray. They look super easy to grab. They are total bait. Touching them now will instantly crowd your Conveyor Belt, leaving no room for the Red and Green marbles you actually need to clear the front line.

Control the belt. That is the only way to survive this specific layout. The starting receiver Boxes give you a very strict opening script. Follow this exact release order to safely carve open the middle of the board.

Opening the Center in Marble Sort Level 347

Your absolute first goal is to clear out the Red and Green receivers so the board can cycle new Boxes in. Leave the outer edges completely alone.

1. Tap the bottom-center Red box. Send it straight down to clear the far-left receiver on the Conveyor Belt.
2. Grab the bottom-center Green box sitting right next to where that Red one was.
3. Look to the left and right flanks. There is a Green box on the lower-left side and another Green box on the lower-right side. Tap both of them immediately.
4. These three Green boxes will instantly clear the remaining three bottom Boxes on the belt.
5. Ignore the bottom-center Yellow box for a brief second. Wait to see what the next wave of bottom Boxes reveals. If a Yellow receiver drops in, tap that center Yellow box to clear it out of your way.

Breaking the Ice and Dropping Locks in Marble Sort Level 347

Once those initial Red and Green Boxes clear, the whole dynamic of the board shifts. The lower layers will cycle into new colors, often bringing up Dark Green, Yellow, and eventually Orange and Blue. Now you have to deal with the ice wall and the horizontal locks.

1. Target the specific colors directly under the Iced Boxes. Dropping the Orange, Brown, or Pink boxes from the second row (only if their matching receivers are finally active below) will crack the ice above them.
2. Focus heavily on clearing the boxes supporting the yellow rings. Once the boxes directly under the yellow locks are cleared, the pins retract.
3. The moment the yellow locks fall, the top left and top right columns of Hidden Boxes become playable. Do not spam them.
4. Treat every question mark as a massive risk. Drop one Hidden Box at a time so you don't flood the Conveyor Belt with a weird color like Purple or Light Blue when you don't have a receiver for it.
5. Start clearing out the dead center to activate the blue Tunnel. It will start spitting out its four hidden boxes one by one. Prioritize clearing the front of the Tunnel whenever you have an open slot so it doesn't bottleneck the late game.

Surviving the Late Game Squeeze in Marble Sort Level 347

As the center empties out, the board transitions into a chaotic mix of secondary colors. You will start seeing Orange, Light Blue, Blue, Pink, and Purple receivers flood the Conveyor Belt.

1. Keep a close eye on the remaining Iced Boxes. If you clear out the board too fast and leave an Iced Box stranded without any adjacent boxes to trigger it, you will fail the level.
2. Pull from the top-left and top-right columns only when your Conveyor Belt is completely empty. The hidden drops up there love to throw late-game colors at you.
3. Save the isolated Brown or White boxes for the absolute end. They usually don't have matching receivers until the very last wave.

Patience wins this layout. Clear the front Greens, break the center ice to drop the locks, and strictly match your hidden drops to the active bottom Boxes. Control your taps and the board will easily open up.
