Step-by-step solution
- 1) Tap the Light Pink marbles in the second column from the left of the Top Tray to instantly clear the front-right bottom box.
- 2) Tap the Orange marbles in the third column to clear that box, then reach over to the rightmost column and release the Purple pieces.
- 3) Stop tapping entirely: hold back the three greens (Light, Bright, Dark) plus the Dark Blue pieces sitting on the front row, since dropping them will clog the belt.
- 4) Clearing those first three boxes drops the lower rows, pulling down the Tunnels and cracking the first few Mystery Boxes.
- 5) Watch the newly revealed columns for a cluster of Red marbles, and drop them immediately to clear the stubborn Red bottom box in the front row.
- 6) With the far-left Light Green receiver now live, select the Light Green pieces resting near the Top Tray's middle.
- 7) As the Tunnels empty out, drop the Brown and Yellow marbles carefully, always checking the bottom box is ready before committing them to the belt.
- 8) When the Iced Box slides into the front row, clear the Dark Blue and Dark Green boxes flanking it to thaw it, then drop its required color and flush the remaining top columns to finish.

Frequently Asked Questions
What is the main trap to avoid in Level 643?
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 643?
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 643?
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 643 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.
