Marble Sort Level 660 Guide: The Yellow Bait and Triple Tunnel Trap

Marble Sort Level 660 is a masterclass in baiting you into a quick loss. The board looks open at first glance. It is not. You are boxed in by a very specific hidden obstacle chain and some brutal color placement in the front row. If you tap the most obvious colors first, you will jam your board immediately.

The main threat here is a massive Conveyor Belt jam caused by the center marbles. You need to control your drops, ignore the obvious moves, and surgically dismantle the side columns first. Let’s break down exactly how this board is rigged.

The Iced Tunnel pattern in Marble Sort Level 660

This exact layout is designed to trap impatient players. The bottom Boxes dictate everything. Your front active row contains a White Box, a Purple Box, a Light Blue Box, and a Dark Green Box. You have to clear at least one of these before the board really opens up.

Look directly behind that front row of Boxes. The second row is holding a Light Green Box, two Yellow Boxes, and a White Box. This queue order is the key to the whole puzzle.

Now look at the Top Tray. The front, completely exposed edge reads left-to-right: Dark Green, Yellow, Yellow, Light Green, White, Purple, Dark Green.

Do you see the trap? The most accessible marbles right in the middle are Yellow and Light Green. But you do not have an active Yellow or Light Green Box in the front row! If you tap those Yellow marbles, they will drop onto your Conveyor Belt and sit there. They will eat up your limited slots and choke your progress before the level even starts.

Above that bait row sits a horizontal line of three ice-covered marbles (Purple, Orange, Light Blue). These block access to the upper half of the board.

Finally, the entire perimeter is locked down by three heavy Tunnels. On the far left edge, there is a Tunnel marked with a '4'. On the far right edge, another Tunnel is marked with a '4'. Dead top center is a Tunnel marked with a '3', covering a vertical stack of iced Pink and Green marbles. You cannot access the deep corners of this board until those Tunnels empty out.

The priority in Marble Sort 660 is clearing out the side Dark Green marbles to open up the flanks. We have to bypass the center trap entirely. Leave the bait alone.

Dodging the Yellow bait in Marble Sort Level 660

Your first moves must be precise. We need to clear space on the Top Tray without clogging the belt.

1. Locate the isolated Dark Green marble on the far left edge and the other Dark Green marble on the far right edge of the Top Tray.
2. Tap both of them. Send them down to fill the active Dark Green Box on the front right. You will need one more Dark Green marble to clear it, which will drop as the board shifts.
3. Grab the exposed White marble on the right side and drop it for the front-left White Box.
4. Tap the exposed Purple marble on the right side. Send it toward the Purple Box.
5. Do absolutely nothing with the two Yellow marbles and the Light Green marble sitting in the front center. Ignore them entirely. Tapping them now is an instant game over.
6. Look at the horizontal row of iced marbles just behind the front line. Now that the edges are clearing, tap the iced Purple marble on the left and the iced Light Blue marble on the right to start feeding the remaining front Boxes.

Breaking the Tunnels in Marble Sort Level 660

Once you clear your first bottom Box, the board state shifts dramatically. The hidden back rows slide forward, and the side mechanics trigger.

1. As soon as the front White or Dark Green Box clears, the hidden second row moves up. This finally gives you active Yellow Boxes.
2. Now it is safe to tap those two center Yellow marbles that have been blocking the middle of the Top Tray. Clear them out to open up the core of the board.
3. With the center hollowed out, the side Tunnels will start to release their payload. The left '4' Tunnel and right '4' Tunnel will drop Red, Blue, and Light Green marbles into play.
4. Catch these newly dropped marbles quickly. Prioritize matching the Blue marbles into the Light Blue Box that has been sitting in your front row since the level started.
5. Next, target the top-center '3' Tunnel. Clearing the marbles directly below it will force it to open, exposing the vertical column of iced Pink and Green marbles.
6. Watch your Conveyor Belt very closely here. The Tunnels spit out multiple colors in quick succession. If you blindly tap everything dropping from the side Tunnels, you will run out of space. Only pull colors from the Tunnels if you have the corresponding bottom Box active.

The late-game cleanup in Marble Sort Level 660

The hardest part of this level is over once the top '3' Tunnel empties. Now you just have to manage the final staggered drops without making a silly mistake.

1. The bottom Boxes will now reveal their third layer, which includes Orange, deep Green, and more White Boxes.
2. Target the cracked Orange iced marble sitting in the dead center of the board. You need this out of the way to reach the final top-row clusters.
3. Match the remaining Pink and Green iced marbles that fell out of the central Tunnel.
4. Empty the remaining side clusters. The left side hides a stubborn Red marble near the top corner. Wait for the Red Box to slide forward before touching it.
5. Keep your belt clean. You have plenty of visibility now. Sort the final Blue and Light Green marbles into the last remaining Boxes to clear the board.
