Marble Sort Level 747 Guide: Unlocking the Arrow Box Chains

Stuck on Marble Sort Level 747? Yeah, this one looks like a nightmare. The board is dominated by two sets of Arrow Boxes that create a central blockade, and two suspicious Gift Boxes at the very top. The key to this level is ignoring the bait at the top and methodically dismantling the puzzle in the middle row by row.

The Top Tray is almost entirely useless at the start, filled with Mystery Boxes and the two Gift Boxes. The real action is in the center, where a cluster of red, green, yellow, and blue blocks are locked behind Arrow Boxes. Your bottom Boxes are arranged in five standard columns, but the order is everything. Getting this wrong will jam your Conveyor Belt instantly. The main trap is thinking you need to deal with the top of the board first. You don't.

The Arrow Box Gauntlet in Marble Sort Level 747

This board is designed to trick you into making a move that will clog the entire system. Before you tap anything, you need to understand the layout of Marble Sort 747. The core of the puzzle is a 3x7 grid of blocks in the middle of the screen.

The top row of this grid is a single blue and orange block. Below it is the real problem: a row controlled by Arrow Boxes. You’ll see a blue Arrow Box pointing at a light green block, and a yellow Arrow Box also pointing at it. This means the light green block is the key; clearing it unlocks both the blue and yellow blocks. The same pattern exists on the right: a dark blue Arrow Box and an orange Arrow Box both point at a teal block. Clearing that teal block is the only way to release them.

The bait is at the very top of the screen. You have a blue block and a white block sitting next to two Gift Boxes, each marked with a "4". Clearing these blocks will trigger the Gift Boxes, which will then likely reveal the Mystery Boxes above them. However, the bottom Boxes for blue and white/light blue are buried deep in the columns below. If you release them early, they have nowhere to go. They will get stuck on the Conveyor Belt, block all other marbles, and you will fail the level.

Your first moves must be precise. You have to start by releasing the only two blocks in the middle row that aren't locked by arrows: the light green one and the teal one. Clearing these two specific blocks is the first step to collapsing the entire central structure.

Marble Sort Level 747 Step-by-Step Walkthrough

Follow this exact order of operations to clear the board without jamming the Conveyor Belt. Do not deviate from the plan, especially at the start.

Starting with the Center Unlocks

Your goal here is to ignore everything in the Top Tray and focus exclusively on the center. The Mystery Boxes and Gift Boxes are endgame material.

1. Do NOT touch the top blue or white blocks. Leave them completely alone.
2. Locate the light green block in the middle row (the one being pointed at by two arrows). Release it. Send it down to the far-right bottom Box, which is also light green.
3. Now, find the teal block in that same row (also being pointed at by two arrows). Release it. It matches the green bottom Box in the fourth column from the left.
4. Clearing these two blocks unlocks the four Arrow Boxes next to them. This is the first major change to the board. The path is now open to solve the rest of the middle section.

Solving the Arrow Box Puzzle

With the two key blocks gone, the Arrow Boxes are now active. You can clear them and the blocks below them in a specific sequence to open up the board completely.

1. The top row of your bottom Boxes should now be: Red (far left), Yellow, Blue, and two empty slots where you cleared the greens.
2. Release the blue Arrow Box on the left. Send it to the blue bottom Box in the center column.
3. Next, release the yellow Arrow Box. Drop it into the yellow bottom Box right next to the red one.
4. You now have a clear shot at the red block that was between the Arrow Boxes. Release it and send it to the final remaining top-row Box on the far left. The entire top layer of bottom Boxes is now clear.
5. This reveals the next layer of bottom Boxes. You can now begin clearing the "pop-it" style blocks from the bottom row of the middle section.
6. Systematically match the newly available blocks (light green, yellow, reds, orange, purple) to their corresponding bottom Boxes. Work from left to right to keep the Conveyor Belt clear.

Activating the Gift Boxes for the Win

Only after you have cleared the majority of the middle section should you even think about the top of the board. By now, you should have cleared enough layers of bottom Boxes to create a path for the top blue and white blocks.

1. Check your remaining bottom Boxes. You should have a clear path to a blue Box and a light blue/white Box.
2. Release the blue block from the very top of the screen. Send it to its matching Box. This will trigger the left Gift Box, causing four new Boxes to appear.
3. Release the white/light blue block from the top. Send it to its destination. This triggers the right Gift Box, revealing another four Boxes.
4. The board is now fully open. The Mystery Boxes will reveal their colors, giving you all the marbles you need to clear the remaining bottom Boxes. Finish the level by matching the final colors.
