Marble Sort Level 670 Guide: The Triple Tunnel Blockade

Look at this layout. Marble Sort Level 670 throws a massive visual wall right in your face. The entire middle of the board is choked out by three massive horizontal Tunnels. If you tap the wrong starting colors, those tubes will flood your board and end your run early.

You have to manage a very specific front-to-back clear here. You are dealing with hidden colors, delayed drops, and a nasty set of locked boxes at the bottom. Let’s break down exactly how to crack this one open.

The Triple Tunnel trap in Marble Sort Level 670

You need to know exactly where everything sits before you make your first move. The Top Tray is heavily segmented.

At the very top, you have an orange block, a dark blue block, and a multicolored Surprise Bag sitting right in the top middle. Flanking that bag are two blue Panels with a "3" on them. You cannot touch what is behind those panels until you clear three bottom Boxes.

The middle is entirely blocked by three massive horizontal striped Tunnels. You cannot see what is inside them. You just have to trust that they hold the colors you will desperately need later.

Right below those tunnels sits a light blue block, a cyan block, a second Surprise Bag, a light green block, and a yellow block. Finally, the very bottom row of the Top Tray—the only stuff you can hit on turn one—gives you a light green block, a yellow block, a dark blue block, and a red block.

Now look down at your lower Boxes. You have four columns. Your top active targets are dark blue, white, dark blue, and yellow.

Here is the problem. You only have dark blue and yellow marbles available in the Top Tray. You have absolutely zero white marbles exposed for that second column. That white Box is going to stall the whole left side of your board. Worse, if you look deeper into the bottom stacks, row three holds a Lock and Key trap. There is a locked red Box in column two and a locked white Box in column three.

If you just start tapping colors because they look open, you will fill your Conveyor Belt with light green and red marbles. That is pure bait. You have nowhere to put them.

You have to be surgical here. One greedy tap will jam your belt and ruin the run. Follow this release order to pull the right pieces without choking your space.

Escaping the opening bait in Marble Sort Level 670

Your first few moves dictate whether you survive the opening sequence.

1. Tap the dark blue block sitting in the bottom right middle of the Top Tray. This feeds the top left and top right-middle dark blue Boxes.
2. Tap the yellow block sitting right next to it. Send those down into the top right yellow Box.
3. Completely ignore the light green and red blocks on the bottom row. Touching them right now is a trap. You do not have active Boxes for them.
4. Focus on the center. Pop that lower Surprise Bag. You need to find white marbles immediately to feed the top-left-middle white Box.
5. If the bag gives you white, clear that box. If it does not, you will need to trigger the bottom horizontal Tunnel to spill its contents and find your white marbles.

Surviving the Tunnel spill in Marble Sort Level 670

Once you clear those initial top Boxes, the board dynamic completely flips. The horizontal Tunnels will start dumping marbles onto the Conveyor Belt.

1. Watch your Conveyor Belt capacity. The Tunnels will unleash a mix of cyan, purple, and white marbles.
2. Route the white marbles into the middle Boxes to clear out the upper layers.
3. As the left side opens up, you will expose a light green Box. Now you can finally tap that bait light green block you left behind on turn one.
4. Keep clearing downward until you hit the pink and light green marble blocks in the middle of the Top Tray. Releasing these is the key to the entire level.
5. When you drop these specific mid-board blocks, two silver keys will fly down from the top.
6. Watch the keys unlock the red Box and white Box sitting in the third row.

The final Lock and Key cleanup in Marble Sort Level 670

With the padlocks gone, the bottom of the board is finally wide open. The pressure drops, but you still have to manage the delayed top mechanics.

1. Now that you have cleared enough lower Boxes, the top blue Panels will count down to zero and vanish.
2. Grab the orange and dark red/brown blocks from the top corners.
3. Feed the orange marbles into the newly exposed orange Boxes in column three.
4. Match the dark red/brown marbles into the deep right-side Boxes.
5. Your final remaining Boxes will demand dark green and pink. Carefully pull the remaining scattered marbles from the Conveyor Belt to finish off the bottom stacks and clear the board.
