Marble Sort Level 69 Guide: The Triple Tunnel and Mystery Box Trap

Marble Sort Level 69 is a massive bottleneck. You drop into the level and immediately face a jagged, pyramid-shaped Top Tray heavily loaded with Blue, Brown, and Pink marbles. The real problem sits right below. Your lower sorting area is divided into four deep columns, and the outer edges are infested with Mystery Box traps.

You cannot see what colors those outer bottom Boxes need. You only know the front row demands Purple and Blue right out of the gate. To make things worse, the Top Tray features three separate Tunnels holding back crucial pieces, and several marbles are tied together as Connected Boxes. Make the wrong first tap, and your Conveyor Belt will fill up with dead colors before you even crack the first tunnel. Let's break down exactly how to clear this board.

The Outer Mystery Board Pattern in Marble Sort Level 69

This board is designed to bait you into a quick game over. You need to look closely at the front line of the Top Tray. Reading left to right, you have Orange, Cyan, Brown, Blue, Purple, and Orange marbles ready to drop.

Now look at your open bottom Boxes. The front row requires Purple, Blue, Purple, and Purple.

Do you see the trap? The game gives you easily accessible Orange and Cyan marbles right at the front of the Top Tray, but there are zero active bottom Boxes for those colors. If you tap that front-left Orange marble or the front-right Orange marble, they will just sit on your Conveyor Belt and burn your limited space. They are pure bait.

Your true safe route is straight down the middle. There is a massive vertical stack of Blue marbles in the right-center of the Top Tray. You also have scattered Purple pieces that you must carefully extract to feed the demanding front row of bottom Boxes.

The left side of the Top Tray features two Green marbles locked together as Connected Boxes. Tapping one forces both to drop. On the right side, a Pink and Cyan marble share the same connected fate. Meanwhile, three Tunnels (marked with a 3) sit at the top and upper edges of the board. You cannot reach them until the front clears, meaning the late game is completely hidden from you. Everything relies on cracking the outer Mystery Box traps safely.

Follow this exact release order to keep your belt clean and open up the hidden back rows.

Surviving the Front Row Bait in Marble Sort Level 69

Your only goal right now is clearing the front line of Purple and Blue bottom Boxes without touching the toxic outer colors in the Top Tray.

1. Target the front Blue bottom Box first. Tap the single Blue marble sitting in the middle-right of the Top Tray's front row.
2. Immediately follow up by tapping the Blue marbles stacked directly behind it in that vertical column. This rapid deployment instantly clears the first Blue bottom Box and gets it out of your way.
3. Switch your focus to the Purple bottom Boxes. Release the Purple marble sitting in the front right of the Top Tray.
4. Carefully pick off the remaining accessible Purple marbles higher up in the center grid. Route them down to clear the front line.
5. Do not touch the front Orange or Cyan marbles. Leave the green Connected Boxes on the left completely alone. Your Conveyor Belt needs to remain open for the upcoming reveals.

Cracking the Mystery Boxes and Tunnels in Marble Sort Level 69

Clearing the front line triggers a massive shift. The Mystery Box panels in the outer lower columns will now flip and reveal their true colors. This is where the board opens up.

1. Check the newly revealed bottom Boxes on the far left and far right. You finally have targets for the colors you ignored earlier.
2. If the new Boxes demand Brown or Orange, start feeding them the front-row Brown and Orange marbles from the Top Tray. This removes the bait pieces safely.
3. Now activate the green Connected Boxes on the left. Since you have cleared the front clutter, dropping two green pieces at once won't choke your Conveyor Belt. Route them into the newly opened middle bottom Boxes.
4. Work your way up the grid to expose the three Tunnels. These are marked with a 3, meaning they each hold three hidden marbles. Start clearing the Pink and Brown tiles directly blocking their entrances.
5. Drop the Pink and Cyan Connected Boxes on the right side only when you have a guaranteed open Box for at least one of those colors.

Emptying the Tunnels for the Win in Marble Sort Level 69

The final phase requires strict Conveyor Belt management. The remaining lower Boxes are buried deep, and the Tunnels will start spitting out unpredictable colors.

1. Focus entirely on the marbles dropping out of the top and side Tunnels. They will drop onto the board one by one.
2. Keep at least two slots open on your Conveyor Belt at all times. The final Mystery Box reveals at the very back of the lower tray can sometimes ask for colors you don't immediately have.
3. Match the newly deployed tunnel marbles into the back-row Brown and Blue bottom Boxes.
4. Clear the final few straggling pieces from the upper corners to finish the level. Stay patient, don't rush your taps, and the board will clear.
