Marble Sort Level 73 Walkthrough & Solution

Level 73 Board Overview: Two Puzzles Sharing One Belt

Level 73 splits the Top Tray into two zones that play by different rules. The left side is a narrow, two-column strip stacked with Dark Green, Light Green, and Purple, capped by two Tunnels marked with a 2. At the very bottom of that strip sits an x2 Multiplier Gate — anything you drop through it comes out doubled. The right side is a chunky three-column block where all your early moves happen.

The colors running the show here are Dark Blue, Light Blue, Light Pink, and Dark Green, with White, Orange, Purple, and Yellow filling in the gaps. Your starting receiver Boxes ask for Light Pink, Orange, and White. The row behind them wants Light Blue, Dark Blue, and Dark Green — but you can’t touch that row until the front one is gone.

One block matters more than it looks: an exposed Dark Blue on the right side. It’s bait. Dropping it before its Box cycles in just burns a Conveyor Belt slot you desperately need.

The Trap in Marble Sort Level 73

The board wants you to tap whatever matches and ignore the belt. Here’s how each zone is rigged:

• Left strip: everything valuable is locked behind a sequence. The Multiplier Gate only pays off if you feed it a color whose Box is already active, and the Tunnels won’t open until the visible stack below them is cleared.
• Right block: White, Dark Blue, and Light Pink sit at the exposed edges. Only White and Light Pink have open Boxes at the start. The Dark Blue has to wait for the second receiver row.
• The belt: this is the real boss. Digging out the buried colors on the right forces you to float a marble or two, so every slot you waste on early bait tightens the noose.

The level’s rhythm is strict: gut the right side first, flip the receiver row, then exploit the gate and Tunnels on the left.

Marble Sort Level 73 Step-by-Step Walkthrough

Follow the release order. The opening is not negotiable.

Phase one: strip the right-side front row

1. Drop the exposed White block in the middle-left of the right block into the White Box.
2. That uncovers an Orange block. Send it straight into the Orange Box.
3. Tap the Light Pink block on the far-right edge. It covers the remaining Light Pink demand.
4. Stop tapping. The front receiver row collapses and the board rotates.

Phase two: wake up the Multiplier Gate

The new front row asks for Light Blue, Dark Blue, and Dark Green. Now the left strip is finally useful.

5. Drop the lowest Dark Green block on the left through the x2 Multiplier Gate. The doubled marbles fill the Dark Green Box almost by themselves.
6. The pull-down ticks both Tunnels from 2 to 1.
7. Go back to the right side and drop that Dark Blue block you ignored earlier. Its Box is live now.
8. Tap the Light Blue block revealed above it into the front-left Box.
9. If a Light Green or Purple block stands between you and buried Light Blue or Dark Green, park exactly one on the belt — no more.

Phase three: Tunnel spawns and cleanup

10. Clear the leftover Purple and Light Green blocks on the left until the visible columns are empty.
11. Both Tunnels pop and drop hidden Dark Blue and Dark Green blocks. Route every one of them through the Multiplier Gate — the back receiver rows need huge counts of these two colors, and doubling is the only sane way to fill them.
12. The last Boxes are Light Blue and Yellow. Pull the Yellow cluster from the top-right of the tray, parking any blocking Purple on the belt, and close it out.

Level 73 Tips Recap

• Never drop a color through the Multiplier Gate before its Box is active — doubled marbles with nowhere to go end runs.
• The right side feeds the left side: clear White, Orange, and Light Pink before touching anything near the gate.
• Treat the belt as single-slot parking during phase two; overflow here is how most attempts die.
