Marble Sort Level 73 Guide: The Multiplier Gate and Tunnel Trap

Marble Sort Level 73 hits you with a violently split board. You are forced to juggle two completely different logic puzzles at the same time. The left side is a tightly restricted column trap. The right side is a sprawling, multi-layered mess.

If you just start tapping colors that match, you will lose. The dominant colors here—Dark Blue, Light Blue, Light Pink, and Dark Green—are stacked in a way that baits you into filling your Conveyor Belt early. You need a strict order of operations to survive this one. The true controller of this level is the isolated left section featuring both Tunnels and a highly valuable Multiplier Gate. Miss the timing on those, and your board jams permanently.

The Dual-Zone Board Pattern in Marble Sort Level 73

Look at how the game isolates the left side of the Top Tray. It is only two columns wide. At the very bottom sits an x2 Multiplier Gate. Any box dropped through that gate doubles its marbles. But look above it. You have Dark Green, Light Green, and Purple boxes entirely trapped under two Tunnels. Both Tunnels are stamped with a '2', meaning there are hidden boxes waiting inside. You cannot access the hidden colors until you clear the lower pieces, but you shouldn't touch those lower pieces until their matching bottom Boxes are exposed.

Now look at the right side of the Top Tray. This is a bulky, three-column block where your opening moves actually live. White, Dark Blue, and Light Pink boxes sit at the lowest edges.

Your bottom Boxes dictate everything. The front row demands Light Pink, Orange, and White. You cannot reach the crucial second layer of bottom Boxes (which need Light Blue, Dark Blue, and Dark Green) until that entire front row is wiped out.

The biggest trap in Marble Sort 73 sits on the right side. That exposed Dark Blue box looks incredibly tempting to tap early. Leave it alone. If you drop Dark Blue before the front row clears, it will just sit on your Conveyor Belt burning a precious slot. You need every inch of that belt to unearth the colors buried in the right-side stack.

Marble Sort Level 73 Step-by-Step Walkthrough

Here is the exact release order to dismantle this board safely. Keep your eyes on the front row of the bottom Boxes and do not touch the left side until the right side is partially hollowed out.

Clearing the Right-Side Blockade in Marble Sort Level 73

Your first priority is stripping away the front row of bottom Boxes to expose the real puzzle underneath.

Target the middle-left column of the main right-side block. Drop the exposed White box directly into the third bottom Box.
This immediately uncovers an Orange box. Drop that Orange box straight down to clear the second bottom Box.
Shift your focus to the far right edge of the Top Tray. Drop the exposed Light Pink box to satisfy the first and fourth bottom Boxes.
Stop tapping. The entire front layer is now gone. The board shifts.
Your active bottom Boxes now demand Light Blue, Dark Blue, and Dark Green. This is where the board opens up.

Activating the Multiplier Gate in Marble Sort Level 73

With the second layer of bottom Boxes exposed, it is finally time to interact with the dangerous left side of the board. Order is everything here.

Notice the Dark Green bottom Box is now active in the third slot. Look at the isolated left side of the Top Tray.
Drop the bottom-most Dark Green box through the x2 Multiplier Gate. The gate doubles the marbles, rapidly filling and clearing the bottom Box.
This action pulls down the left stack. The Tunnels at the top will tick down from '2' to '1', preparing to spit out hidden boxes.
Shift back to the right side of the Top Tray. That Dark Blue box you ignored earlier is now useful. Drop it to clear the Dark Blue bottom Box.
Dropping the Dark Blue box exposes a Light Blue box above it. Drop that Light Blue box to clear the front-left bottom Box.
You will likely need to float one Light Green or Purple box onto the Conveyor Belt to access the remaining Light Blue and Dark Green boxes buried higher up in the right stack. Keep the belt as empty as possible.

Managing the Tunnel Reveal in Marble Sort Level 73

Once the middle layers are cleared, the Tunnels take over the late game. They hide the exact colors you need to finish the final rows.

Clear the remaining Purple and Light Green boxes on the left side to fully empty the visible columns.
The Tunnels will now pop open. They will drop hidden Dark Blue and Dark Green boxes onto the board.
Because these drop on the left side, route them straight through the Multiplier Gate. This is critical for clearing the massive Dark Blue and Dark Green requirements in the back rows of the bottom Boxes.
The final bottom Boxes are entirely Light Blue and Yellow. Clean up the remaining Yellow boxes clustered at the top-right of the Top Tray. Drop them carefully, ensuring your Conveyor Belt doesn't overflow at the very last second. Use the belt to hold the top-row Purple boxes if they block your final Yellow clears.
