Marble Sort Level 773 — Walkthrough and Solution

Marble Sort Level 773 presents a board that seems chaotic, but the main obstacle is a counter with the number 4 on the left, holding an Orange marble hostage. The Lock and Key are distractions, at least initially. Your primary goal is to clear any four Boxes to deactivate that counter, which then releases the Orange marble and unlocks the mid-game.

The layout splits into two zones. On the right, a 4x5 grid contains a jumble of Light Blue, Pink, Yellow, Teal, Purple, Orange, and Brown marbles, with a Red dispenser on the far right edge. On the left, a Key Booster sits at the top, with single Green and Dark Blue marbles below. In the center, a Lock blocks a Yellow and a Pink marble. To the left of that Lock, the 4-counter holds the Orange marble. A Tunnel is positioned at the top of the third column, ready to release four mystery marbles. The bottom Boxes are stacked with Red, Dark Blue, Light Blue, and White marbles, but note that there are no Pink or Yellow Boxes visible initially—those colors are trapped behind the Lock.

Marble Sort Level 773 Walkthrough

The bottom Boxes, from left to right, demand: Red, Dark Blue, Light Blue, White, White, Orange, and Red—but the exact order may vary. The key imbalance is that the top grid contains many Pinks and Yellows, yet no Boxes for them are open until later. The trap is to waste moves trying to unlock the Lock early; instead, focus on clearing accessible colors.

The single biggest trap is the Lock and Key mechanic. It tempts you to use the Key early, but doing so will jam the Conveyor Belt because there are no Pink or Yellow Boxes to receive those marbles. The 4-counter is your real target.

How to Beat Marble Sort Level 773 — Step-by-Step

Phase one: Deactivate the 4-counter

1. Tap the Light Blue marble at the top of the grid, and route it to the Light Blue Box on the right.
2. Drop the Orange marble from the fourth column into the Orange Box in the middle stacks.
3. Slide the Red marble from the bottom right into the Red Box on the far left.
4. Feed the Dark Blue marble from the top row into the second Box from the left.
5. After these four clears, the counter unlocks, releasing the Orange marble it held.

Phase two: Manage the mid-game

1. Guide the newly released Orange marble into the next available Orange Box.
2. Clear the White marbles from the center columns, as they are accessible and will lower the stacks.
3. Use the Rainbow Dispenser only when a useless marble like Purple or Teal blocks a useful one like Red or Dark Blue. Tap it to complete a set and move the blocker onto the belt.
4. Do not tap the Tunnel yet; it will dump four marbles and likely choke the belt.

Phase three: Finish the level

1. When a Yellow or Pink Box appears under the stacks, tap the Key Booster to open the Lock, releasing the Yellow and Pink marbles so you can clear them.
2. Prepare for the Red Dispenser to start dropping Red marbles; keep Red Boxes ready and clear other colors first.
3. As the board clears, empty the Tunnel last, ensuring the Conveyor Belt has room for the four marbles.

Tips & tricks

• Always prioritize clearing Boxes that are easy to reach, like Light Blue and Orange early on, to activate the counter quickly.
• Keep the Conveyor Belt as empty as possible; avoid unnecessary moves that fill it with marbles you can't immediately place.
• Use the Rainbow Dispenser sparingly and only when it directly helps clear a blockage, not for random fun.

Common mistakes

• Tapping the Tunnel early, which floods the belt and often leads to a loss.
• Using the Key before any Pink or Yellow Boxes are available, causing those marbles to sit on the belt forever.
• Ignoring the 4-counter and focusing on the Lock, which wastes moves and allows the belt to jam.
