Step-by-step solution
- 1) Open by tapping the lowest Purple tile in column four and then the bottom Light Blue tile sitting in column five, both of which drop freely even though the padlock chains the center.
- 2) Pull the Light Blue off the bottom of column seven, then swing your attention over to the far-left columns.
- 3) Take the lowest Green tile from column one and then the Pink tile from column two, and feed them into the newly unlocked White and Green Arrow Boxes on the left flank.
- 4) Keep climbing strictly up columns one and two, and leave the Black and Light Blue Arrow Box columns over on the right untouched.
- 5) Poke the last pink tile tucked in the top-left corner — collecting it snags the key; the center chain shatters and reveals a tall Green, Blue, Black, and Brown stack.
- 6) Drain the Purple and Green tiles out of the exposed middle first, and only poke right-side Arrow tiles when you need a Black or Light Blue piece to fill an active box.
- 7) Clear the remaining Black and Brown boxes, then drop the last Arrow tiles from columns six and seven, and finish by matching the Light Blue and Green marbles that remain.

Frequently Asked Questions
What is the main trap to avoid in Level 313?
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 313?
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 313?
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 313 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.
