Frequently Asked Questions

What is the main trap to avoid in Level 637?

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 637?

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 637?

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 637 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.
