Step-by-step solution

Quick answer
  1. 1) Ignore the Lock and Key entirely at the start and hunt for easy clears: send the top light blue marble to its Box in the right-most columns.
  2. 2) Feed the orange marble resting on the fourth column of the grid into the orange Box waiting in the middle stacks.
  3. 3) Grab the red marble at the bottom right of the grid for the far-left red Box, and the dark blue marble on the top row for the second Box from the left.
  4. 4) That fourth clear pops the '4' counter on the left and releases the orange marble it was holding, so send that orange to the next available Box.
  5. 5) Prioritize the two white Boxes in the center columns to lower the stacks and expose what sits underneath.
  6. 6) Use the Rainbow Dispenser when a useless marble like purple or teal blocks a useful one such as red or dark blue, completing a set to shift that marble off the board.
  7. 7) Keep the Tunnel untouched for now; only open it once more than half of the lower Boxes are gone and the belt has plenty of room.
  8. 8) When a yellow or pink Box appears under the stacks, tap the Key Booster to open the Lock, empty all the non-red receivers you can before the red dispenser starts, and save the Tunnel for last with an empty belt.

Level 773 Key, the Lock, and the Counter

one’ve got one seal on this middle from this board, one pass that doesn’t seem into hold a matching Box , and two different counters.

this trick into sphere Sort 773 is knowing what to ignore.

this seal plus pass sit trap, at least with the first half of the level.

the real mission sits into empty four exact cases into disable one counter over the left, which gates your progress.

Let’s break down how into get that done without jamming the Conveyor Belt .

Level 773 Locked Grid

First, let's get one handle on this weird layout.

this upper Tray is split into two main sections.

over this east sits one big 4x5 grid from mixed spheres: light azure, pink, yellow, teal, purple, orange, and brown.

over this far east, one crimson dispenser is waiting to cause trouble later.

this west side is where all the mechanics are.

At this very upper west sits one pass Booster , which one likely have active for this level.

Below that sit single green and dark blue marbles.

on this middle, one seal blocks a yellow and a pink marble.

into its west rests one crucial counter using one '4' over it, holding an orange marble hostage.

atlast, at this upper from this third lane, one Tunnel promises into release four secret marbles when you least want it to.

this lower cases sit stacked deep, mostly using red, dark blue, light blue, and white.

this upper rack sits full from pinks plus yellows blocked via one seal , but here sit zero rose or gold Boxes in sight at the start.

this goal sits into ignore this locked spheres plus focus over what one can clear to satisfy that '4' counter.

Level 773 Level Overview

Follow this order, plus one’ll keep this Conveyor Belt clear and the path open.

Level 773 First Goal: Pop the '4' Counter

this just job at this start from sphere Sort 773 sits into empty any four cases into unlock the orange marble on the left.

Do not try into get to the locked marbles.

Target Easy Matches: Start using shades that hold a clear path to an open Box .

here’s one light azure sphere at this upper from this grid plus one light azure Box accessible in the right-most columns.

empty some amber: Find this amber sphere on the fourth column of the main grid.

some amber case sits waiting for it in the middle stacks.

Find one crimson sphere: One crimson Box is waiting on the far left.

this easiest crimson sphere into take sits on the bottom right of the main grid.

take one Dark azure: this second case from this left needs a dark blue marble.

There's one conveniently located over the top row of the main grid.

Counter Unlocked: Once that fourth case sits cleared, this counter over this west shall activate, releasing this orange marble it was holding.

Level 773 Mid-Game Strategy: Managing the Board

using this counter gone, one hold one bit more freedom, but also more risk.

this Conveyor track may get packed fast if you make the wrong choice.

this seal sits yet one distraction—continue to ignore it for now.

Use this fresh amber sphere: this first thing one should do sits use the orange marble you just unlocked.

Send that to the next available orange Box .

empty this ivory cases: one hold two white Boxes in the center columns.

this ivory spheres sit one bit stuck on the main grid, but they are accessible.

Prioritize clearing those into bottom the stacks and reveal what’s underneath.

Use this Rainbow Dispenser: That colorful creature over the left is your secret weapon.

Wait until one useless sphere (as violet or teal) sits blocking one useful one (like red or dark blue).

Use this rainbow sphere into complete one built, which gets this useless sphere off this board plus onto this belt, where you can hopefully manage it.

Resist this Tunnel: Seriously, do not touch this Tunnel yet.

that shall dump four spheres onto this belt and likely cause an instant loss.

Wait until one hold cleared at least half from this bottom Boxes and have plenty of room.

Level 773 Finishing

this wall from this level is a race against clutter.

Once this stacks sit low, one’ll hold to deal with the remaining mechanics.

When into Use this pass: You've made that this far without the Lock .

But if one gold or rose case sits revealed under this initial stacks, that's your cue.

choose this Key Booster icon to open the Lock .

This releases this gold plus rose spheres so you can finally clear those Boxes .

If zero such cases appear, one may use this pass simply into get this gold plus rose spheres out from this way to access other colors behind them.

Brace with this crimson Dispenser: That crimson piece over this right will eventually start dropping red marbles.

Try into empty out as many non-crimson Boxes as you can before this happens.

When this crimson spheres start coming, make sure one have red Boxes ready.

Empty this Tunnel Last: Once this board sits mostly empty plus you're running out from taps, it's finally time to tap the Tunnel .

Make sure this Conveyor Belt is as empty as possible.

this four spheres shall send, plus one can sort them into the remaining Boxes .

via focusing over this '4' counter first plus ignoring this Lock , you bypass the level's main trap.

Keep the Conveyor track tidy, plus Marble Sort 773 is totally beatable.

Frequently Asked Questions

What is the main trap to avoid in Level 773?

The biggest mistake is tapping colors that have no active bottom Box yet. They park on your Conveyor Belt and burn limited slots, so clear the shades that actually have receivers first.

How should I open Level 773?

Ignore the upper layers and aim at the bottom row of the Top Tray. Feed the colors that already have open boxes, then work upward once the lower lanes shift.

When does the midgame color change happen in Level 773?

After the opening boxes fall, the lower columns swap what they demand. Watch for the new shades and only pull blocks that match a box sitting at the front of a lower lane.

Any tip for finishing Level 773 clean?

Keep at least a few empty belt slots before poking mystery or hidden boxes. Feed a revealed color the moment it matches an active box, and fall back to visible marbles when the belt gets tight.
