Marble Sort Level 152 Guide: The Triple Tunnel Trap

Marble Sort Level 152 is a masterclass in bait-and-switch gameplay. You drop into the level and see a nicely organized pyramid in the Top Tray, but do not let it fool you. This board wants you to jam your Conveyor Belt within the first five moves. The dominant colors starting out are Brown, Orange, Light Blue, Red, and Green. Behind them, a nasty array of obstacles is waiting to choke out your playable space.

Your top section features a staggered formation. You have a solid row of bright marbles up front, three numbered Tunnels sitting ominously in the middle rows, and a roof made entirely of grey Hidden Boxes. Down below, your bottom receiving area holds four active columns. The front row asks for Brown, Red, Brown, and Green. Right behind those front targets, you have a dead zone of grey Mystery Boxes. You cannot see what they need until you clear the front line. This combination of top Tunnels and bottom Mystery Boxes controls the entire flow of the level. If you pull the wrong colors down early, you will run out of space before the real puzzle even starts.

The Pyramid Squeeze in Marble Sort Level 152

Let us break down exactly what you are staring at because the layout here is a trap. The bottom receiving area has four slots. The front active Boxes are Brown, Red, Brown, and Green. Behind them sits a row of Mystery Boxes, followed by White, Green, Pink, and Light Blue in the deep back.

Now look at your Top Tray. The front line is five columns wide. From left to right, you have Light Blue, Brown, Brown, Orange, and Orange.

See the problem? You have two Brown Boxes waiting at the bottom. That requires six Brown marbles. Luckily, you have exactly two full Brown marble blocks sitting in the front-middle of the Top Tray. You also have Orange and Light Blue blocks in that front row. They look perfectly safe to tap. They are total bait. There is no active bottom Box for Orange or Light Blue yet. Tapping them just dumps them onto the Conveyor Belt, stealing precious slots.

Behind the front row, you have Red on the far left, Light Blue in the mid-left, a gap in the center, and Red and Green on the right.

Higher up sits the real nightmare of Marble Sort Level 152. You have three Tunnels. Each has a number "3" stamped on the front. Two sit lower on the left and right flanks. One sits higher up in the top center. Above them is a pyramid roof of six Hidden Boxes. You have no idea what colors are inside them, which means you cannot plan your late game until you force the Tunnels open. The game is daring you to click the front colors randomly. If you do, those Tunnels will eventually dump colors like Dark Blue and White onto your board. If you do not have the right bottom Boxes exposed by then, your Conveyor Belt fills up instantly.

Marble Sort Level 152 Step-by-Step Walkthrough

You need ruthless discipline to beat this level. You must control the Conveyor Belt. Every single tap in the early game has to serve a specific purpose. We are ignoring half the board until we clear the roadblocks.

Breaking the Brown Barrier in Marble Sort Level 152

The opening moves dictate your survival. Do not touch the Orange. Do not touch the Light Blue. Focus strictly on feeding the bottom Boxes that are actually open.

Tap the two Brown blocks sitting dead center in the front row of the Top Tray. This drops six Brown marbles onto the Conveyor Belt and instantly clears both of the Brown bottom Boxes.
Look at the lower receiving area. Clearing the Browns just exposed some of the grey Mystery Boxes.
Go back to the Top Tray. You need to clear the Red and Green front Boxes at the bottom. Tapping the front Browns exposed a Light Blue, a Red, and a Green block.
Tap the Red block (located on the right side behind the Browns) and the Green block. This clears your remaining front-row bottom Boxes.
Stop and look at your Conveyor Belt. It should be relatively empty right now. If you tapped the Orange or Light Blue blocks earlier, they are currently hogging space. Leave them up top.

Unlocking the Mystery Boxes in Marble Sort Level 152

Once the front line of bottom Boxes is gone, the midgame begins. The grey Mystery Boxes reveal their true colors. This is where the level usually kills you if you aren't paying attention.

Check the newly revealed bottom Boxes. You will likely see Orange, Pink, Light Blue, or more Red.
Now you can finally tap the two Orange blocks sitting on the right side of the Top Tray. Send them down to clear the corresponding bottom Box.
Tap the front-left Light Blue block. You have a Light Blue bottom Box waiting in the back rows, but you need to clear the Mystery Box in front of it first.
Start working on the second layer of the Top Tray. You need to drop the Red block on the far left and the remaining Light Blue blocks to feed the newly opened lower slots.
Do not tap the Tunnels yet. Whenever you tap a block in front of a Tunnel, its counter drops. Once it hits zero, it spits out its hidden marbles.

Emptying the Tunnels in Marble Sort Level 152

This is the failure point. The Tunnels hold late-game colors that do not have active bottom Boxes early on. The top center Tunnel hides White and Dark Blue marbles. The flanking Tunnels hide Green and Dark Blue marbles.

Keep matching the mid-board colors (Pink, Light Blue, Green) until you have a clear bottom Box ready for White or Dark Blue.
Once your lower board is primed, pull from the blocks sitting directly in front of the Tunnels to drop their counters from "1" to "0".
The Tunnels will push Dark Blue and White marbles onto the Top Tray. Route them directly into your bottom Boxes.
With the Tunnels empty, the top grey Hidden Boxes finally activate. Because you kept your Conveyor Belt clean through the midgame, you now have plenty of room to catch whatever random colors these blocks drop and sort them into the final remaining slots to win the level.
