Marble Sort Level 45 Walkthrough & Solution

Level 45 Board Overview: The Green Famine and Three Tunnels

Level 45 starves you of the one color you need most. The bottom receivers open with Green, Green, Purple, Green — three out of four slots begging for Green. Now scan the front of the Top Tray: two Cyan blocks on the left, Purple, Red, another Purple, and Orange on the far right. Not a single Green in sight.

The Green supply is locked in two places. One batch sits inside the Connected Boxes on the right side of the second row. The other is buried deep on the left, underneath a Tunnel. And the upper half of the board is a fortress: Connected Box pairs wrapping the middle rows, three separate Tunnels each showing a count of 3, and a final Light Blue / Dark Blue Connected pair capping the very peak.

Your palette here is Cyan, Purple, Green, Pink, and Orange. The matching is easy — surviving the first five drops without clogging the Conveyor Belt is the real level.

The Trap in Marble Sort Level 45

This board is built to make you panic-tap. Here is what each part of the layout is doing to you:

• Front row: pure bait except for the two Purple blocks. The Cyan pair, the Red, and the far-right Orange have no open Box. Tap them blindly and they rot on the belt.
• Second row, right side: the Connected Boxes chaining Orange to Green. This is your first real Green source, but you can only reach it by moving the front-row Orange and Red out of the way.
• Middle columns: two sets of Connected Boxes sit shoulder to shoulder, with the big central Tunnel (count 3) looming above them.
• Top-left and top-right Tunnels: two more countdowns of 3 guarding the flanks, with Green hidden behind the left one.
• The peak: one last Connected pair tying Light Blue and Dark Blue together. Pull it early and the fallout buries your belt.

The level wants you to hammer the front-row Cyan and Red to “dig faster.” Do the opposite: every drop must either fill a Box or expose one that will.

Marble Sort Level 45 Step-by-Step Walkthrough

The opening sequence is tight. Follow it exactly — one sloppy belt drop ruins your spacing for the mid-game.

Opening: reach the buried Green

1. Tap both free Purple blocks in the front row. They drop straight into the Purple Box, the only playable target on the board.
2. Clearing that Box reveals an Orange/Brown Box underneath. That is your foothold for the right side.
3. Drop the far-right Orange block of the Top Tray.
4. Slide the front-row Red block onto the Conveyor Belt. It has no home yet — this is pure unblocking, and it is the only belt sacrifice you make in the opening.
5. The right-side Connected Boxes are now exposed. Break the Orange-Green chain and let the Green marbles pour into the three waiting Green Boxes.

Mid-game: count down the three Tunnels

Once the Green Boxes clear, the board flips personality — Dark Blue, Pink, and more Purple targets surface, and your attention moves upstairs.

6. Feed the central Tunnel: drop the Dark Blue and Orange blocks sitting in the middle columns to tick its counter down from 3.
7. Leave the two Cyan blocks on the bottom left untouched. They are still bait until a Cyan Box cycles in.
8. Work the center and right columns to uncover the Pink Connected Boxes and another Purple block, and match everything into the newly revealed receivers.
9. When the middle Tunnel hits zero it spits out a stream of hidden colors. Clear whatever it drops before digging anywhere else — a flat area under the Tunnels prevents ugly vertical pile-ups.

Cleanup: the flanks and the peak

The left and right Tunnels finally open, dumping Dark Blue and Green onto a board where belt space is suddenly precious.

10. Let the belt work for you: if Red or Dark Blue is already parked there, wait for its Box instead of tapping fresh blocks from the tray.
11. Attack the left-side Tunnel by clearing the remaining Green and Dark Blue on the left wing until its counter hits zero.
12. Save the peak for last. Only break the Light Blue / Dark Blue Connected pair when you have at least four empty belt slots to catch the fallout.
13. Empty the leftover Pink and Orange on the right wing to finish the board.

Level 45 Tips Recap

• The front row is a lie: only the two Purple blocks are safe opening taps.
• One planned belt sacrifice (the Red) is fine; two is a jam. Park nothing else early.
• Treat Tunnel output as top priority the moment it lands, and never crack the peak Connected pair without four free belt slots.
