Step-by-step solution
- 1) Open by tapping the Pink cluster in column three of the Top Tray, then the Pink cluster in column five, so both center Pink bottom boxes fill in one move.
- 2) Leave the far-left and far-right Dark Red alone and skip the Light Green too, since neither color has an active box and either would choke your belt.
- 3) To reach the Cyan your outer boxes need, drop the Blue Box from column four and the Orange Box from column six onto the Conveyor Belt.
- 4) With those two columns cleared, pull the exposed Cyan marbles down to fill the starved outer bottom boxes and wipe out the initial frontline.
- 5) After the first row clears, work the lower Lock and Key first: send the White and Blue keys to snap the bottom horizontal bar and release the yellow center.
- 6) In the back half, poke one Mystery Box at a time, and only drop a revealed color when it matches an active bottom box or a stranded belt marble.
- 7) Finish by securing the Red and Orange bottom boxes to break the top golden bar, which drops the purple center and lets the remaining marbles cascade into place.

Frequently Asked Questions
What is the main trap to avoid in Level 520?
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 520?
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 520?
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 520 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.
