PACK OUTa puzzle about moving day

A free logic puzzle in your browser. Every number is on screen before you place anything, and there's no timer.

Load the truck backwards, like everyone says, and the bike arrives crushed.

You plan a moving crew's load before a single box moves. The truck is drawn side-on: cab on the left, one back door on the right. Two rules. Nothing may crush what it rests on, and at every stop, that stop's things have to slide straight out the back.

This is job 2, running on the game's own code. Tap something on the crew's list, then tap the truck where it goes. Close the doors and watch the crew unload.

The answer has two empty spaces in it

Spoilers for the demo. Try it first.

The job's brief tells you to think backwards: the storage unit is the first stop, so its things go on last, by the door. That's the bike and two boxes. The sofa, the lamp and two more boxes ride on to the house.

So you do it, and you pack it tight, the way anyone who's moved would. Sofa against the cab, bike against the sofa. Then the top row, cab to door: house boxes, the lamp, and the storage boxes last, nearest the door. Which is right on top of the bike.

The bike bears nothing. Its gauge goes red the moment a box touches it, and the claim sheet comes back at $350.

The clean load puts the bike on the floor at the door with nothing above it. Two spaces of truck sit empty, on purpose, right over the bike. (The tight load had two empty spaces too. They were at the back, where they did nothing.) The storage boxes ride deeper in, on the top row, on top of the sofa and a house box.

And they still come off first, because the top row is clear all the way to the door. Nearest the door was never the rule. A clear run to the door is.

(The sofa carries three units of weight in that load. It bears exactly three. Equal is fine.)

Two rules. You already know both.

Every item on the crew's list (the game calls it the manifest) has a size, a weight and a number for how much weight can rest on it. The game calls that last one bears.

NOTHING CRUSHES

Weight sits on whatever is under it, split evenly across the spaces it touches. A desk that weighs 3, resting half on a box and half on a trunk, puts 1.5 on each. Every placed thing shows a gauge, and if the load goes past what it bears, it's on the claim sheet. Fragile things bear zero: the TV, the bike, the lamp, the mirror.

FIRST STOP, FIRST OFF

At each stop the crew slides out that stop's things, door side first. A thing leaves only if nothing rests on it and its row is clear to the door. Anything in the way goes on the pavement and gets loaded back on. That's a re-handle: 6 minutes of the crew's day, not yours. You're never timed.

That's the whole game.

1,814,400 ways to load job 3. 230 deliver clean.

The game ships with three bots built to lose. One loads straight down the manifest. Two know the trick: last stop in first, one going heaviest first and the other biggest first. A job only made it into the game if all three miss a star on it. (On job 1, one of them gets away with it.) On job 2, both of the clever ones crush the bike.

I wanted to know how rare the right answer is, so I counted every legal way to get the whole manifest onto the truck, graded by the same rules the game uses, with matching boxes counted once:

jobways to fit it allarrive clean
1. Flat 2B216140
2. The Ferry Road double16,380548
3. The professor's books1,814,400230

Job 1 is the warm-up, and most loads work. Job 2 is about 1 in 30. Job 3 fills the truck to the last of its 18 spaces with 12 things, and only about 1 in 7,900 ways of doing that gets everything there in order with nothing broken. Every job has at least one clean load, and Dell, the crew boss, knows where it is.

The counting scripts are on the notes page, and they import the game's rules file directly.

Six jobs

  1. Flat 2B, Linden Street. One stop. "Mind the telly." Dell teaches you here, one step at a time, and only moves on when you do the thing he asked.
  2. The Ferry Road double. Two stops, one door. The demo.
  3. The professor's books. Books weigh 3 and bear 4. Stack three and the bottom one bursts, so they have to lie in a row across the top.
  4. The dorm drop. R turns things on their side. The fridge, the washer and the dryer refuse: they travel upright. The mattress goes in standing on its edge.
  5. The Greaves estate. Ruth Greaves's things go three ways: the charity shop takes the books, then her son Tom's, then storage. Three colors, one door.
  6. The piano. Twenty-four spaces and twenty-four spaces of cargo. The piano weighs 10, it travels upright, and it goes to the first stop.
Job 5 in the full game, mid-drive at the first stop: a three-colour load in the truck, a crushed box of books at the bottom by the cab, and a box and a box of books already on the pavement.
Job 5 in the full game, loaded by the bot that goes straight down the manifest. The red box of books has two more on top of it, and at the very first stop the crew is already filling the pavement.

If you've loaded a real truck

You'll spot what's missing, so here it is:

What it gets right: heavy goes low, fragile goes on top or alone, and the stuff you need first can't be under the stuff you need last. You knew all three. Try all three at once in an 18-space truck.

Questions

Is it free?
Yes. No account, no ads.
Controls?
Click an item on the list, then click the truck. R turns it, Z undoes, H gets Dell's note, Enter closes the doors, and Space starts the season.
Is it like Unpacking?
It's the other end of the move, and it can go wrong. Unpacking is the boxes after. This is the truck before, and the bike can arrive crushed.
What if I get it wrong?
It still delivers. You get a claim sheet and the minutes it cost the crew, and R reloads the job.
I'm stuck.
Press H. Dell's note hands you one piece of a proved load, with no penalty. The report just says: "Dell left a note on this one. No shame in that."
Does it save?
Your stars do, in your browser. Finish the demo and job 2's stars carry over, as long as you open the game in the same browser.
Phone?
The demo, yes. The full game won't start without a keyboard. On a phone, the Send it to your laptop button passes the link along.

The piano gets off at the first stop

Job 6 has no empty spaces at all. The piano weighs 10, and the choir's robes ride on top of it.

P.S. Job 3 has 230 clean loads. Dell knows one of them and will show it to you if you ask. The other 229 earn the same three stars, but Dell won't recognize them, so you're on your own.
