Step-by-step solution
- 1) Select the Purple pieces in the middle of the Top Tray, sending them to the belt to empty the first Purple receiver below.
- 2) Tap the Red marbles just to the right of the center to clear the Red bottom box in the second slot.
- 3) Select the Blue pieces at the left of the front row to drain the Blue receiver on the far right.
- 4) Claim the final Purples from the upper right Tunnel, which carries exactly three, to empty the leftover front receiver.
- 5) Emptying those groups sets off the rockets, which blast outward and up, tearing through the lower grey Hidden Box layers and exposing fresh Red, Teal, Blue, and Purple in the middle.
- 6) With the new demands for Light Green, White, and Pink, let the Light Green string slide into place before tapping anything else, and release the White from the front corners only when a White box appears.
- 7) Let out the Pink pieces from the lower-left Tunnel to drain the ready Pink receiver, and pair any color that surfaces at once with the active queue.
- 8) Send out the Red from the upper-left Tunnel when a Red receiver rotates up, drop the White from the lower-right Tunnel, and clear the leftover Green and Red Tunnels to close the level.

Frequently Asked Questions
What is the main trap to avoid in Level 640?
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 640?
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 640?
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 640 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.
