Step-by-step solution
- 1) Clear the front row first: pull the left-side Connected Boxes so the Magenta fills the front bottom Box while the Dark Blue parks on the Conveyor Belt.
- 2) Grab the single Red cluster sitting across the Top Tray's front row, then the Red tucked behind the front Light Blue, to start filling the first Red bottom Box.
- 3) Move to the right edge and tap the other accessible Red cluster so the front row of bottom Boxes fully clears; leave the right-side Yellow and Light Pink Connected Boxes alone.
- 4) When the second row slides forward demanding Dark Blue and Light Blue, the belt Dark Blue flies straight into the fresh Dark Blue Box.
- 5) Now tap the front Light Blue and Dark Blue clusters you skipped at the start to wipe the new front line and reach the clusters touching the central Crate.
- 6) Clear any playable color beside the Crate to shatter it, exposing four hidden clusters in the middle, usually Red, Green, White, and one more key color.
- 7) Poke the central Surprise Bags one at a time, always keeping two empty belt slots so a dead-pull never jams you.
- 8) Pull the right-side Connected Boxes only once a Yellow or Light Pink bottom Box slides to the front, then match the Tunnels' output to finish the board.
Level 420 Central Crate and Surprise Bag Trap
sphere Sort Level 420 hits one using one heavily fortified middle plus one from the meanest opening baits in the game
one sit staring down one huge wooden box parked blind in the middle of the board
that pieces this entire top part, locking away this crucial middle shades you need for the midgame
into make matters worse, this upper half from this board is completely covered in Surprise Bags
one hold zero idea what shades sit concealing beneath those grey, question-marked fabrics until one clear the front lines
the dominant starting shades sit Red, Dark Blue, Light Blue, and Magenta
But seeing one shade plus safely playing it are two different things

this lower Boxes are your only source of truth
this very head line from this bottom section is demanding heavy amounts of Red
one hold three crimson lower cases plus one Magenta lower case blocking access to everything else behind them
this absolute head line consists from Light azure, Red, Dark Blue, and another Dark Blue
the brain wants into clear the front row immediately
here sit zero Light azure or Dark azure bottom Boxes in the active front row
Dropping those head blues shall right choke the Conveyor track, leaving one using zero room into pull the colors you actually need
this sides from the Top Tray are equally dangerous
over this west edge, one hold Connected Boxes linking Dark Blue to Magenta
over this east edge, one hold Connected Boxes linking Yellow to Light Pink
Pulling those forces both shades down at the exact same time
Below those linked groups sit four Tunnels, marked using 4s and 3s
those Tunnels shall spit out secret groups one via one, but just after you clear the space above them
this star from this show sits this central wooden box marked with a giant X
This box hides four entire clusters beneath it
that shall just shatter plus available onto if one successfully send three from the clusters directly touching its sides
Surrounding this box is a wall of Surprise Bags
This means once one start digging into this middle, you will be guessing blindly
the track management holds into be flawless since one bad bring from one Surprise Bag can end your run instantly

Ignore this tempting shades over this head lines plus dig with this exact marbles that clear the front row immediately
Level 420 Surviving the opening trap
this just goal east now sits clearing this three crimson lower Boxes and the single Magenta bottom Box
Leave the front Light Blue entirely alone
choose this Connected cases over the left side of the Top Tray
This sends both the Dark Blue and the Magenta
this Magenta shall right fill this front bottom Box and clear it
this Dark azure will safely sit on your Conveyor Belt
take this single crimson group parked on the front row of the Top Tray
This starts filling this first Red bottom Box
bring this crimson group sitting right behind the front Light Blue
Now look into this east side from this board plus grab the other accessible Red cluster

Do not touch this east-side Connected cases (the Yellow and Light Pink)
Level 420 Shattering the Crate
using this head line from bottom Boxes gone, the game completely shifts
this second row of bottom Boxes slides forward
Now this game sits asking for Dark Blue and Light Blue
Remember that Dark azure parked on your Conveyor Belt from step one?
that immediately flies into one newly exposed Dark Blue bottom Box
choose this head Light azure plus this head Dark azure groups one ignored at the start of the game
They shall send down plus clear out the new front line
one sit now actively clearing this clusters touching the central Crate
Look with any playable shade directly adjacent to the wood
This uncovers four secret groups east on this middle from this board, usually exposing crimson, Green, White, and another key color
Level 420 Managing the RNG finish
this board sits now available, but the danger is heavily spiked
this upper half sits fully covered on Surprise Bags, plus this side Tunnels sit ready to bleed out remaining clusters
Start tapping the central Surprise Bags
choose one bag, spot what shade sends into the Conveyor track, plus check if that matches an active bottom Box
Never choose one Surprise Bag if one just hold one or two available slots on your Conveyor Belt
one should always leave room for a dead-pull
If one bag dumps one shade one do not want, one should hold room into hold that while you dig for the matching color
bring this east-side Connected cases (gold plus Light rose) just when one spot one gold or Light rose bottom Box slide into the front position
They hold three into four hidden clusters each
Since one shattered this box plus cleared this middle, one now hold this available track room to catch whatever the Tunnels spit out
Keep matching this newly exposed lower Boxes until the board is completely clean
