Step-by-step solution
- 1) Do not touch the front-row Red or Green clusters, since no bottom box can catch them and they would instantly flood your Conveyor Belt.
- 2) Open by tapping the Light Blue cluster and the Orange cluster at the very front, sending them into the Light Blue Box in column two and the Orange Box in column three.
- 3) That carve leaves a gap in the front wall, so reach the single White marbles in the second row and drop them into the White boxes in columns one and four.
- 4) Once those opening boxes fall, Red boxes appear at the bottom, so now slam the big Red clusters in the front left and front middle to wipe out the matching receivers.
- 5) Clearing the Red and Green clusters frees the whole board, so move on to the iced Orange and Light Blue marbles and drop each one the moment its box is active to shatter the ice.
- 6) Leave the linked pairs untouched until an open receiver appears for one side of the chain, and only then break the Purple-and-Green connection.
- 7) In the final stretch, feed the Pink cluster in the upper left into the Pink boxes as they open, one at a time, to avoid a last-second jam.

on sphere Sort Level 521 , this board actively tries into trick you into an immediate game over.

using limited track room, one huge group shall jam the queue and force a restart.
this Light azure plus amber groups on this front row are your only safe moves.
Clearing them sits this just way into physically carve one path into this ivory spheres waiting in the second and third rows.
Adding into this chaos, this center-board sits littered using iced marbles and tied connection links.

this board sits now wide open, exposing the midgame traps.
one shall now face spheres encased on cracked ice, starting using the iced Orange and Light Blue marbles.
one should match those specific colors to shatter the ice.
Prioritize dropping those iced spheres onto this Conveyor track as soon as their matching case appears at the bottom.
Pay close attention into this spheres tied together using tiny colored links (as the chained Purple and Green marbles).
Never choose one tied pair unless one hold one matching case ready with at least one from those colors, preferably both.
Level 521 Clearing the Back Rows

route them on slowly into avoid one last-second jam and finish the level.
Frequently Asked Questions
What is the main trap to avoid in Level 521?
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 521?
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 521?
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 521 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.
