Marble Sort Level 105 Guide: The Numbered Tunnel Trap

The worst part of this board is the immediate bottleneck. You start with front-row receivers that demand specific colors, but those colors are completely buried.

In Marble Sort Level 105, you are forced into a nasty game of conveyor management right from the first tap. You have dominant clumps of Light Blue, Green, and Purple staring you in the face. Do not touch them. They are pure bait. The real progression is locked behind a strict sequence of Yellow and Brown clears, and you have to dig through junk to find them. Add a countdown Tunnel on the right wall and a wrapped '5' obstacle in the top center, and you have a recipe for a very fast game over if you pull the wrong top layers.

Let's break down this exact layout and find the safe path through.

The unique board pattern in Marble Sort Level 105

Read the board before you make a single move. Your success completely depends on understanding where the required marbles are hiding inside the Top Tray.

Look at your bottom receiver area. The absolute front row of Boxes gives you your starting targets: a Yellow, a Brown, a Yellow, and a Brown. You cannot do anything else until these four are fed. Behind them, the second row holds an Orange, a Yellow, a Light Pink, and another Yellow. The third row hides Pink, Orange, White, and Pink.

Now look up at the Top Tray. The very bottom row of this upper section is not made of marbles. It is a solid shelf of waiting Boxes: a Yellow, a Brown, a Purple, a Brown, and a Green. These will drop down later, but right now, they form the floor for the marble stacks above them.

To feed your bottom Yellow and Brown Boxes, you need to extract Yellow and Brown marbles. The problem is their placement.

Far left column: Orange sitting on Black.
Second column: Purple over Green over Light Blue over Green.
Third column (under the wrapped '5'): Purple over Yellow over Red.
Fourth column: Brown over Black.
Fifth column: Light Pink over Orange over Light Blue over Light Pink.
Far right column: Yellow over Orange over Light Blue.

You only have immediate access to a few top-layer colors. You can grab an Orange, a Purple, a Brown, a Light Pink, and a Yellow. That right-side Yellow is great. That center Brown is great. But to get the rest of the matching marbles to actually clear a Box, you have to pull the other top colors and let them sit on your Conveyor Belt.

You also have two massive countdown threats monitoring your progress. On the right side wall, a blue Tunnel displays a '3'. It will not trigger until you manage three full clears. In the top center of the board, a wrapped square displays a '5'. You have to survive long enough to clear five Boxes before that center column opens up.

The jam risk on this specific board sits on the left and right edges. You will be tempted to pull the top Orange and Light Pink marbles to dig down. This is actually required, but it will crowd your Conveyor Belt extremely fast. You have to balance holding garbage colors with finding exactly enough Yellows and Browns to secure your first clear.

Your priority route is entirely dictated by that front row of alternating bottom Boxes. Do not pull any marble unless it directly helps you reach a Yellow or a Brown, or if it is completely blocking a column you desperately need.

Surviving the first taps in Marble Sort Level 105

The opening moves are going to feel incredibly tight. You have to float several wrong colors just to reach your targets.

Tap the Yellow marble on the far right column.
Tap the Brown marble in the fourth column. You now have one of each on the belt, but you need three to clear.
You must dig into the third column to reach the hidden Yellow. To do this, tap the top Purple marble. Let it sit on the Conveyor Belt.
Now grab that Yellow from the third column.
You still need more Yellows and Browns. Go to the fifth column. Pull the top Light Pink marble, then pull the Orange marble beneath it.
Pull the far-left top Orange marble so it matches with the one you just pulled. You will likely end up holding a mix of Orange, Light Pink, Red, and Black on your belt. This feels dangerous, but it is necessary.
Keep digging down the far right column to pull the Orange out of the way, giving you access to the lower layers.
Once you expose the required Yellows and Browns, feed them into the bottom Boxes.

Managing the Tunnel reveal in Marble Sort Level 105

Clearing those initial front-row Boxes changes the entire identity of Marble Sort Level 105. The board state aggressively shifts once you hit your third clear.

Watch the right wall Tunnel. As soon as you clear your third Box, the '3' hits zero. The Tunnel activates and spits out a solid Black Box directly into your receiver area.
At this same time, the second row of lower Boxes slides forward. Your new active targets will include Black, Orange, and Brown.
This is your relief valve. You have been holding Black and Orange marbles on your Conveyor Belt since the opening moves. Immediately flush those floating Black and Orange marbles into their new respective Boxes.
Your Conveyor Belt is now clean. The massive pressure is gone.
Keep clearing to hit the magic number five. Once you score your fifth clear, the wrapped '5' obstacle in the top center shatters.

Clearing the final stacks in Marble Sort Level 105

The endgame of Marble Sort 105 is much softer than the opening, provided you did not clog your belt with the Light Blue and Green bait from the second column.

With the center unlocked and the Tunnel empty, the top stacks will start collapsing.
Focus on the Light Pink and Red marbles next. Feed them into the newly revealed bottom Boxes.
The solid Boxes that were acting as the floor of the Top Tray (the Purple, Green, and Light Blue ones) will now drop down into the bottom receiver area.
You finally have a place for all those stacked Light Blue and Green marbles on the left side. Pull them down methodically.
Finish off the remaining Purple stack to clear the board. Always ensure you have a corresponding Box waiting before pulling the final deep-layer colors.
