Step-by-step solution
- 1) Open by taking the orange stones found at the tray's lower-middle and feeding them up into the orange Box that leads Column 1.
- 2) Take the dark green stones on the tray's lower-right to empty the dark green Box that leads Column 2 and flip the first question box.
- 3) Slide the two pink/red piles from the bottom line into the pink/red Boxes that head Column 3 and Column 4, then wait until you see what the grey boxes in Column 2 and Column 4 ask for.
- 4) Force the left side downward, taking the light pink stones over there to empty the next Box heading Column 1.
- 5) If those fresh question boxes want light blue or deep blue, remove the stones parked against the golden key marker and send them only when a matching receiver shows up.
- 6) Once the lane is open, strike the block that carries the golden key so the top-center chain snaps and the light green, deep blue, and yellow row breaks free.
- 7) Review your arrow dependencies now, moving the light green and yellow stones only after the receivers they point to have fallen, then edge inward from the cleared left using the frozen orange and light blue stones once two neighbors are dropped.
- 8) Turn to the tray's upper-right zone to satisfy any brown or purple the question boxes need, avoid parking more than two unmatched stones, and empty the final pink and blue stacks in sequence to close the board.

Frequently Asked Questions
What is the main trap to avoid in Level 307?
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 307?
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 307?
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 307 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.
