Marble Sort Level 674 Guide: The Mystery Box Wall and Double Tunnel Trap
This board is a masterclass in bait. You load in and immediately see bright, juicy marble clusters sitting right at the front of the screen. You want to tap them. Don't.
Marble Sort Level 674 locks your progress behind a massive, centralized blockade. You are dealing with dominant hits of Yellow, Red, White, and Green. But the real nightmare is the thick wall of grey Mystery Boxes and Surprise Bags blocking the entire mid-board. Above that? Two massive blue-striped Tunnels holding back the late-game pieces. You have to thread a very specific needle at the start. One greedy tap on the wrong color will completely jam your Conveyor Belt and end the run.
The Double Tunnel pattern in Marble Sort Level 674
Read the board before you make a single move. This layout is designed to trap you early.
Look at the lower Boxes. You have four columns. The absolute front row requires Yellow, White, Red, and White. Behind those, you have a mix of Orange, Pink, and more Red. You cannot touch anything else until that front line clears.
Now look at the Top Tray. The absolute front line of accessible marble clusters reads exactly like this from left to right: a Green 9-dot cluster, a Pink cluster, a Red cluster, a Yellow cluster, and another Pink cluster. Tucked just slightly up and to the left is a solid White block.
This is the bait. Green and Pink are sitting right in your face. But look down. There are no Green or Pink Boxes in the front row! If you tap that Green or Pink cluster, those marbles will drop down, take up precious space on your Conveyor Belt, and sit there. They will block the White and Yellow marbles you actually need to clear the active lower Boxes.
Above this dangerous front line sits the core obstacle. A massive grid of Mystery Boxes interspersed with grey fabric Surprise Bags. You cannot see what colors are inside. Above that wall sit two large Tunnels bordered in blue, loaded with Arrow Boxes and more mystery mechanics. You have to dig through the bottom, trigger the mystery wall, and empty those Tunnels without clogging the belt.

Discipline is everything here. You have to ignore the easy taps and focus entirely on matching the front bottom row.
Cracking the front row in Marble Sort Level 674
Your first moves dictate the entire run. Play it strict.
- Clear the Yellow and Red. Tap the Yellow 9-dot cluster in the front of the Top Tray. This drops perfectly into the front-left Yellow Box. Immediately tap the Red 9-dot cluster next to it. That clears the Red Box in the third column.
- Hunt the White. Your bottom row still needs two White Boxes cleared. Tap the solid White block sitting on the middle-left edge.
- Ignore the Green and Pink. I cannot stress this enough. Leave the Green and Pink clusters alone. Dropping them now is a guaranteed loss. Let them sit there while you dig for more White marbles.
- Peel the first layer. Clearing the Yellow and Red clusters will expose the bottom row of Mystery Boxes. Once their colors reveal, look for any White marbles. Drop them to clear those front Boxes.

Once the front Yellow, White, and Red lower Boxes clear, the board shifts. The second row of Boxes exposes Orange, Pink, and more Red. Now the game opens up.
- Use the Pink. Now that the front lower Boxes are gone, you have an active Pink Box available. Finally tap those front Pink clusters in the Top Tray. Get them off the board to open the center.
- Pop the Surprise Bags. As you dig into the center grid, the grey fabric Surprise Bags will open. You have no control over what comes out. Route these newly revealed colors carefully. If a bag spits out Purple, but you don't have a Purple Box active yet, leave it alone.
- Activate the Arrow Boxes. You will uncover blocks with white and red arrows. An Arrow Box only unlocks when the space it points to is empty. Focus on clearing the marbles directly in front of their arrows so you can keep the board flowing.
- Manage the belt. The middle game gets incredibly messy. You are going to have exposed Orange, Light Blue, and Green marbles. Only drop a color if the matching Box is physically open. Use your Conveyor Belt as a temporary holding zone for one color max. Two stranded colors will kill your space.
Emptying the Tunnels in Marble Sort Level 674
Clearing the center grid activates the top of the board. The heavy hitters come out to play.
- Pull from the Tunnels. The two blue-striped Tunnels at the top will start dropping their contents forward. You will see more 9-dot clusters, including Yellow and Red, slide down into playable positions.
- Match the late-game Boxes. Your bottom Boxes will now be showing Light Blue, Purple, and Green. You will notice a heavy influx of Green marbles from the left side and Red from the right.
- Clear front-to-back. Keep digging into the Tunnels. Whenever a new Mystery Box drops from a tunnel and reveals its color, prioritize matching it immediately. Keep the Conveyor Belt lean. Finish off the Light Blue and Purple Boxes to wrap up the level.
