About Packing Line

Packing Line turns colour sorting into a live logistics problem — every can arriving on the belt demands a colour-matched box, and the boxes you tap first determine whether the line flows or deadlocks. The order matters because the platform holds only a few boxes at a time, and grabbing the wrong colour leaves later cans with no matching container. Planning which box to place means reading the incoming sequence as a small routing graph: each choice frees or blocks the next slot. The puzzle is not about matching colours alone — it is about sequencing them before the belt runs out of space.

Sorting cans by color sounds simple, but it gets tricky fast. You’ve got to match each can to the right box before the line backs up. Run out of space, and it’s game over. The real fun is planning ahead—deciding which box to use now so you don’t get stuck later. That satisfying click when everything lines up perfectly? Totally addictive.

How to Play Packing Line

  1. Tap a box of the same colour as the can currently on the belt to move it onto the platform.
  2. The can is automatically packed into the box when both are on the platform.
  3. If no matching box is available, tap a new box from the shelf to add it to the platform before the next can arrives.
  4. Keep the platform clear by packing cans as they come; the game ends if the belt stops because no box space remains.
  5. Plan your box selections so that every can colour is matched before the platform fills up.

Tips & Strategies

  • Look ahead at the next two cans on the belt before choosing a box — a colour that repeats soon might be worth saving a slot for.
  • If the same colour arrives twice in a row, place a box for the first can quickly so the slot frees for the second.
  • Avoid cluttering the platform with boxes of the same colour unless the belt shows multiple cans of that colour coming.

Frequently Asked Questions

What happens if I run out of box space on the platform?

The belt stops, and the game ends — that is the only loss condition. You must pack cans faster than they arrive or free slots by packing.

Can I remove a box from the platform after placing it?

No. Once a box is tapped onto the platform, it stays there until a matching can is packed into it. You cannot cancel a placement.

Do cans appear in a fixed order each level?

Yes, each level has a predetermined sequence of can colours. The same level always presents the same order, so you can learn and improve your box plan.

Is there a penalty for placing a box that doesn't match the current can?

There is no penalty, but that box occupies a slot until a matching can arrives. If the platform fills with mismatched boxes, you risk a deadlock.
