Marble Sort Level 412 Guide: The Iced Box and Tunnel Trap

This board is a masterclass in visual deception. At first glance, the layout seems generous because there are loose marbles waiting right at the bottom edge of the Top Tray. Do not fall for it. Marble Sort Level 412 is heavily locked down by two columns of Iced Boxes on the flanks and a pair of stubborn Tunnels clogging the direct center.

Your dominant colors here are Pink, Orange, Green, and Brown. The front row of your bottom Boxes dictates your opening moves entirely: you need to fill a Brown, Orange, Pink, and Purple Box right out of the gate. If you grab the wrong loose marbles, your Conveyor Belt will jam before you even break the ice on the outer columns.

The Frozen Flanks pattern in Marble Sort Level 412

Let’s break down exactly what you are staring at on this specific board. The Top Tray is divided into seven distinct columns, but the mechanics strictly limit what you can touch.

Column 2 is entirely locked by Iced Boxes. You can see a Light Blue, a dark Blue, and a Purple marble trapped in the ice. Column 6 is the exact same trap, freezing a Red, Orange, and Green marble. Because an Iced Box only activates when nearby marbles drop down, columns 1, 3, 5, and 7 are your mandatory working zones. You have to mine out the sides to melt the ice.

Dead center in column 4 is your other massive roadblock. It is a vertical sandwich of obstacles. You have a Red marble, a Tunnel with a '3' countdown, a Green marble, another Tunnel with a '3' countdown, and a Brown marble.

Right at the bottom lip of the Top Tray, sitting below the main grid, are five loose marbles: Purple, Red, Brown, Yellow, and Pink. This is the bait.

Now look at your bottom Boxes. The front active row asks for Brown, Orange, Pink, and Purple. The queues behind them are brutal:

Left queue: Brown, then Orange, then Yellow.
Inner-left queue: Orange, then Brown, then Green, then Orange.
Inner-right queue: Pink, then Green, then Pink, then Pink.
Right queue: Purple, then Pink, then Purple, then Brown.

Notice the trap? There is a loose Red marble at the bottom of the Top Tray, but there is absolutely no Red Box visible in the lower queues. There is a loose Yellow marble, but the Yellow Box is buried three deep on the far left. If you tap that Red or Yellow marble early, they will sit on your Conveyor Belt for half the game, eating up the slots you desperately need to navigate the Iced Boxes.

You need surgical precision to open this board. The entire goal is to clear the front row of Boxes without touching the Red or Yellow bait, allowing you to peel away the outer columns and unfreeze the Iced Boxes.

Dodging the Opening Bait in Marble Sort Level 412

Your first taps must clear the front row of Boxes to reveal the secondary colors. Keep your eyes on Brown, Orange, Pink, and Purple.

Tap the loose Brown marble sitting in the bottom middle of the Top Tray.
Pull the next two Brown marbles from the accessible outer columns. There is one at the bottom of column 5. Snag it.
This clears the front-left Brown Box and pulls the first Orange Box forward. You now have two active Orange Boxes demanding marbles.
Grab the loose Pink and Purple marbles from the bottom corners of the Top Tray. Route them into their respective Boxes on the right side.
Tap the Orange marbles sitting at the bottom of column 1 and column 5. This fills the front Orange Boxes and brings the Green and Yellow Boxes into play.
Leave the loose Red and Yellow marbles exactly where they are. Do not touch them. Your Conveyor Belt needs to remain completely empty for the midgame transition.

Melting the Midgame in Marble Sort Level 412

Clearing those outer bottom marbles will start triggering the release condition for the Iced Boxes in columns 2 and 6. The board is about to open up, but the center Tunnels will become your next major hazard.

Now that the Yellow Box is active on the far left, you can finally tap that loose Yellow marble. Pull the remaining Yellows from column 1 to clear that Box.
Focus on column 3 and column 7. Pull the Green marbles down into the newly revealed Green Boxes in the center queues.
Mining out columns 3, 5, and 7 will shatter the ice on the right side. The Iced Box holding the Green, Orange, and Red marbles will unlock. Drop the Green and Orange marbles immediately into their matching Boxes.
Do not drop the un-iced Red marble yet. Wait until the right-side queues clear out enough to reveal a Red Box.

Popping the Tunnels in Marble Sort Level 412

The flanks are clear. The ice is melting. Now you have to defuse the center column.

Tap the remaining accessible marbles in column 4. This will drop the countdown on the Tunnels from 3 to 0.
Once the top Tunnel hits zero, it will dispense its hidden marbles. Route these directly into the heavy stack of Pink and Purple Boxes waiting on the right side of the board.
Keep the Conveyor Belt moving. Only tap the lower Tunnel when you have exactly two empty slots on your belt, as it will spit out the final blocked colors needed to clear the lingering Brown and Pink Boxes in the back rows.
Sweep up the remaining Red and Light Blue marbles from the left Iced Box to finish the level.
