Marble Sort Level 693 Guide: The Dual Tunnel and Mystery Box Minefield

Marble Sort Level 693 pulls no punches. You load in and immediately see the problem staring back at you. The center of the Top Tray is dominated by two blue Tunnels holding four boxes each. Surrounding them is an absolute minefield of Mystery Boxes.

The dominant colors here are Black, Red, Blue, and Light Green. But having the right colors does not matter if they are stuck behind question marks. You need to clear the front line, but the game is trying to bait you into clogging your Conveyor Belt early. Look at your bottom Boxes. The starting row demands Black and Red. Anything else you tap is going to sit on the belt and choke your space. The ultimate goal is to break through the center to reach the Lock and Key boxes sitting on the upper edges. If you fail to unlock the bottom stacks, your run is completely dead.

The Dual Tunnel pattern in Marble Sort Level 693

Let's break down exactly what you are looking at in Marble Sort 693. The board is arranged to force you into bad decisions.

The Top Tray features a jagged, pyramid-like structure. The absolute front row consists of Black, Black, Red, Light Green, and Blue. Behind them? A messy mix of solid colors and dangerous Mystery Boxes. Behind the first Black box is a Blue box. Behind the second Black box is a Mystery Box. The two central blue Tunnels are stamped with a "4", meaning they will spit out four hidden boxes once the space in front of them is finally cleared.

Your bottom Boxes are stacked four columns wide. The currently exposed targets are Black, Black, Red, and Red. Below those, the stacks get incredibly complicated. You have Light Green, Pink, Orange, and Blue waiting underneath. Even worse, the deeper layers of these bottom Boxes are secured by heavy locks.

The biggest trap on this board is the Light Green and Blue boxes sitting on the right side of the front row. They look like easy targets. They are completely exposed. Do not touch them yet. If you release them, they will drop onto the Conveyor Belt and just sit there. You do not have a Light Green or Blue bottom Box available yet. The right side of your Conveyor Belt will get crowded instantly, leaving you with zero room to maneuver when the Tunnels start dumping their payloads. The entire flow of this level relies on holding back until the exact right bottom Box rises up.

Marble Sort Level 693 Step-by-Step Walkthrough

You need a strict order of operations here. One wrong tap on a Mystery Box will end your run. Keep your eyes on the bottom Boxes and follow this exact release sequence.

Opening the front line in Marble Sort Level 693

The opening moves dictate the rest of the game. You must clear the immediate targets without filling your belt with junk.

1. Tap the two Black boxes in the front left of the Top Tray. They will drop and immediately clear the two Black bottom Boxes.
2. Tap the front Red box in the middle. It will flow into one of the Red bottom Boxes, clearing it out of the way.
3. You now have one Red bottom Box left to clear, but the next visible Red box in the Top Tray is blocked. It sits right behind the front Blue box on the right.
4. Tap the front Blue box. Yes, it will sit on the Conveyor Belt for a moment, but this is a necessary sacrifice to open the board.
5. Tap the Red box that was just exposed. This clears the final Red bottom Box in the starting row.

Surviving the Tunnels and Mystery Boxes in Marble Sort Level 693

Clearing those top bottom Boxes shifts the whole board. New targets cycle in. You now have Light Green, Blue, and Pink targets available at the bottom. This is where the pressure spikes hard.

6. Tap the Light Green box in the front right of the Top Tray. It clears into the newly exposed Light Green bottom Box.
7. Look at the blue Tunnels in the center. They are the engine of this level. The moment the space in front of them is clear, they activate. They will dispense Blue boxes first.
8. Remember that Blue box sitting on your Conveyor Belt from step 4? Now is its time. Use the Blue boxes falling out of the Tunnels to clear the Blue bottom Boxes as they rise up. Keep that center lane moving fast.
9. Now you have to face the Mystery Boxes. Tap the front-most one. Watch what color drops. If it drops an Orange or Brown color, stop. Do not tap another one. Wait until you dig deep enough to expose an Orange or Brown bottom Box. If you rapid-fire these hidden boxes, you will lose.

Clearing the final Locks in Marble Sort Level 693

The late game gets incredibly tight. You will see your Conveyor Belt filling up with mixed colors as you dig into the back of the Top Tray.

10. Prioritize the Lock and Key boxes. There is a Pink key box on the far left edge and a dark Green key box on the right. Tap the Pink key box as soon as a Pink bottom Box is ready.
11. Clearing the keys unlocks the bottom rows. This is mandatory. Without those lower bottom Boxes, the marbles on your belt have nowhere to go.
12. Focus entirely on emptying the remaining boxes inside the two central Tunnels. Once the numbers hit zero, the top section of the board unlocks, giving you access to the final grey key boxes.
13. Match the remaining stragglers from the back corners into the final unlocked bottom Boxes to finish the stage. Keep your taps slow and deliberate at the end to avoid a final fatal jam.
