Step-by-step solution
- 1) Leave the side wings and the x2 Multiplier Gates alone, and clear the three exposed Boxes directly below the center Mystery Boxes—Purple, Light Pink, and Dark Red—into their matching bottom receivers.
- 2) Grab the Cyan marble sitting beside the middle Mystery-Box cluster to feed the far-left bottom Box, completing the opening front row.
- 3) As the bottom Boxes slide up to ask for Light Green and White, check the newly revealed center grid first and keep pulling from the middle whenever you get a match.
- 4) Hollow out the entire 2x3 Mystery Box block, and if you need a color not on the center, draw from the inner edges of the side wings rather than passing anything through the x2 gates.
- 5) If you are forced to take a box sitting above a Multiplier Gate for a needed Orange or Pink, keep the Conveyor Belt almost clear so the doubled drop does not clog it.
- 6) Once the middle cross is empty, tap the front boxes of the three top Tunnels to release Light Blue, Dark Red, and White marbles into the aligned bottom Boxes.
- 7) In the final cleanup, pass the stray boxes left over near the far edges through the x2 gates to fill the last receivers, checking each drop so you never double the wrong color.
Level 77 Mystery Box Grid and Multiplier Trap
This board loves into bait you into an early loss.
one load on, spot those shiny side paths, plus want into start clearing the outer edges immediately.
this real problem here sits this huge cross-shaped grid on the center of the Top Tray .
Until one hollow out that middle part, you are playing blind.
Marble Sort Level 77 tests your patience.
one hold into carefully chip away at this head line into show this secret shades as totally ignoring this dangerous doubling mechanics sitting on the wings.
Make this bad bring too first, plus the board shall jam before you even reach the midgame.
Here sits exactly how into break this board down plus keep your momentum going.
Level 77 Cross Formation
Let us look closely at how this exact board is built.
this upper rack is shaped like a giant plus sign.
this upper arm holds three Tunnels , each marked using a "3".
This means here sit three tiers from spheres trapped inside each tunnel, but one cannot even touch them right now.
They sit totally blocked by the center of the cross.
That middle part sits a nasty 2x3 block of Mystery Boxes .
one may see the gray blocks with question marks.
one hold zero idea what colors are hiding in there.
one can't plan your midgame until those are exposed.
one have easy-to-reach colors sitting there.
ivory, Purple, Green, and Pink on the left.
emerald, Pink, Blue, and Orange on the right.
Below those outermost wings sit bright green Multiplier Gates marked with x2 .
Any case one send down this sides shall pass through those gates, doubling this amount of marbles hitting the Conveyor Belt .
If one send that amber case over this east through this Multiplier Gate east now, one get a massive pile of orange marbles.
Those doubled spheres shall sit over the Conveyor track and instantly choke your limited space.
Your starting bottom Boxes dictate everything.
From west into east, the head line needs Cyan, violet, Dark Red, and Pink.
this goal sits into map those exact shades into this safe middle from this upper rack plus completely ignore the Multiplier Gates until later.
Level 77 Level Overview
Success here sits all about order of operations.
We sit going into empty this head line, dig into this secret middle, plus just use this side wings when this lower board demands it.
Level 77 Busting the Front Line
Stick into the center-bottom of the cross.
Look right below the gray Mystery Boxes .
one hold one line from three exposed cases: Purple, Light Pink, and Dark Red.
Dropping that violet, rose, plus Dark crimson shall perfectly route this starting center-west, mid-right, and far-right bottom Boxes .
one yet want Cyan for the far-left bottom Box .
Look just into the right of the central Mystery Boxes .
As one empty that lower line from violet, rose, plus Dark crimson, this secret cases above them shall begin into flip and show their true colors.
Do not touch this cases sitting directly above the x2 Multiplier Gates .
Keep the Conveyor Belt completely clear of unnecessary doubles.
Level 77 Digging Through the Mystery Center
this bottom cases will slide up, changing your required colors.
one shall likely spot one wall from Light Green and White Boxes appear next.
Whenever one fresh lower case slides onto, check this newly revealed shades in the center 2x3 grid first.
Always bring from this center if you have a match.
one want that entire 2x3 part of former Mystery Boxes completely empty.
If one want one shade plus that sits not on this middle, look into this inner rims from this side wings (as the Green boxes near the middle).
one might hold into bring one shade that does not hold some ready lower case just into unblock a piece you desperately need.
Put zero more than three blind spheres on the Conveyor Belt at a time.
As one dig deeper, this bottom cases shall demand colors sitting out on the wings.
When one lower case demands amber or rose, plus one sit forced into use this cases above this Multiplier Gates , make sure this Conveyor Belt is nearly empty.
this doubled spheres drop fast and take up massive space.
Level 77 Opening the Top Tunnels
via this point, this entire middle cross should be empty.
one sit now looking at one U-shape of remaining blocks.
this three Tunnels at this top are finally unblocked.
choose the front boxes on the three Tunnels .
They shall send Light Blue, Dark Red, and White boxes.
since one cleared this middle first, one hold plenty from room to route these new colors.
this lower cases shall line up nicely with these tunnel drops.
empty them immediately into pull the numbers down on the Tunnels .
this last phase is just cleaning up the leftovers.
one shall hold one few stray cases parked over the far edges above the Multiplier Gates .
Since this board sits mostly empty now, one may freely send them through this x2 gates into fill out the last remaining bottom Boxes .
Before the last few taps, make sure one don't accidentally send a doubled stack of the wrong color.
Finish this last lower Box requirement, and the level will clear.
Stay patient, control this center, and respect the doubling gates.
Frequently Asked Questions
What is the main trap to avoid in Level 77?
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 77?
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 77?
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 77 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.
