Marble Sort Level 45 — Walkthrough and Solution

Marble Sort Level 45 is a bottleneck from the opening tap because the bottom wants a colour the top keeps locked away. Your starting Boxes read Green, Green, Purple, and Green — three Greens out of four, and not one is reachable yet. The board serves you Cyan, Purple, Green, Pink, and Orange, and dares you to dig with colours that have no home.

The front row is all bait: a pair of Cyans on the left, then a Purple, a Red, a second Purple, and an Orange on the far right. The Green you need is buried twice over — one batch sits inside Connected Boxes on the right of the second row, another hides deep on the left under a Tunnel. In between, a fat middle Tunnel stamped 3 hangs over two side-by-side Connected Boxes, with a Tunnel on each top corner besides.

Marble Sort Level 45 Walkthrough

Capping the very peak is one last Connected pair that ties Light Blue to Dark Blue, and the rule is the same everywhere: every drop has to earn its slot. Digging with the front Cyans and Reds simply stuffs the belt with pieces you cannot place.

The single playable Box at the start is the Purple in column three, and the bottom row of the tray happens to hold two free Purples. That is your foothold, and from there the whole board unwinds.

How to Beat Marble Sort Level 45 — Step-by-Step

Take the Purple foothold

1. Feed the two free Purple blocks from the bottom row into the Purple Box in column three.
2. That clear pulls an Orange Box and a Brown Box up underneath — your foothold.
3. Drop the Orange block on the far right of the tray into its Box.
4. Shift the Red block off the front row and onto the belt, strictly to clear the lane.
5. You have now exposed the right-side Connected Boxes that link Orange to Green — drop them.
6. The Green marbles stream down and begin feeding the three Green Boxes that have blocked you all level.

Open the three Tunnels

Once the Green Boxes clear, the board flips and shows Dark Blue, Pink, and more Purple targets.

1. Feed the boxes directly under the middle Tunnel — drop the Dark Blue and Orange blocks in the centre columns to push its counter down.
2. Ignore the two Cyan blocks still on the bottom left; they are a trap until a Cyan Box goes live.
3. Focus your clears on the centre and right, matching the Pink Connected Boxes and the extra Purple into their Boxes.
4. When the middle Tunnel hits zero it streams hidden colours, so clear whatever it drops before digging elsewhere.

Settle the top connections

1. As the left and right Tunnels open, they spill a mess of Dark Blue and Green, so let the belt carry the load and wait for matching Boxes to surface.
2. Attack the left Tunnel next by digging through the Green and Dark Blue blocks on the left wing.
3. Hold the very top Light Blue and Dark Blue pairing for the absolute end, and only pull it with four empty slots to spare.
4. Empty the remaining Pink and Orange blocks from the right wing to finish the lower stacks and clear the board.

Tips & tricks

• Only the two free Purples are safe at the start; everything else up front is bait until the greens come free.
• The front-row Red is a deliberate sacrifice — park it on the belt to reach the Orange-Green link behind it.
• Keep the ground under the middle Tunnel flat so its drops never stack into a wall.

Common mistakes

• Digging with the front Cyans and Reds. They have no Boxes ready, so they fill the belt and block the greens you need.
• Pulling the top Light Blue and Dark Blue chain early. It needs four empty slots, and firing it sooner floods the belt.
