Uncle Chop’s Rocket Shop: Guide to Washing Machine Codes [WIP]

All 24 have been found unless some of the marker symbols link to the same puzzle in which case there might be more (I think this is unlikely though).

Please leave a comment if you know how to solve one of the remaining ones! Thanks!

You may have noticed the washing machine in the basement is attached to a keypad with a strange set of keys. It turns out there are a series of hidden puzzles in the game that when solved give codes for this keypad which open the washing machine, giving dialogues, new outfits and achievements. If you want to find and solve these yourself, stop reading now and get to work!

This guide will give locations, solutions and reasoning for all these puzzles in the game. The locations and pictures of the puzzles will not be hidden to make it easier to find the answers for specific ones that you get stuck on, however the solutions and reasoning will have spoiler tags.

Note: You can only enter each code once, if you enter the same code twice it will give the same response as entering a wrong code.

There is a page in the guidebook (located between Reliable Home Power and – Fuel -) that tracks which codes you have entered with a stamp that looks like a Yinyang symbol. If viewed under the blacklight in front of the parts shop at night, it also gives clues to the locations of the puzzles. The puzzles are usually marked with the same Yinyang symbol.

Look for this symbol!

The puzzles will be numbered as follows:

The keys will be referred to in this guide as follows:

You are required to press ENTER at the end of every code to submit your attempt. If you fail, you will be able to retry in a few seconds. If you succeed the washing machine will open.

When viewed in the blacklight, the icons in the guidebook correspond to the location of the puzzle as follows:

???

1 4

Not 100% sure, but this number shows up a lot everywhere throughout the game. It’s also written on the wall just to the right of the keypad.

In the Guidebook, inside the front cover, visible under the blacklight in front of the parts shop.

7 3 2 7 8 3

What you see is what you get. Probably one of the first ones you’re supposed to get, as an introduction to the game mechanic.

In the Guidebook, on the page before the pink AI section, visible under the blacklight in front of the parts shop.

7 3 6 SMILE X BRIMSTONE 1

Overlay the pattern on the keypad, the dot tells you where to start

Inside the Warehouse VR where you need to find the correct 3-digit box.

5 5 7 4 1 5 4 8 6 3 7 2

There are 4 shelves that are labelled 1 2 3 4. Each of these has one 3-digit box stored on it. The answer is the four 3-digit numbers combined in shelf order (12 numbers total).

In the Guidebook, on the page before the Headlights section, visible under the blacklight in front of the parts shop.

9 4 2 5 7 3

Plotting each set of functions on a graph draws the icons of the buttons.
There is an example here: https://www.desmos.com/calculator/daagjajjgi
Click the circular icon to the left of “Nth Symbol” to show and hide each one.

In the Guidebook, across from the “Emotional Shutdown” page in the AI section, visible under the blacklight in front of the parts shop.

Here are the numbers in text form if you want to use it:
14-09-14-05/7-10-23-06/08-11-24-07/11-04-15-09/
10-19-25-22/11-14-01-10/14-07-18-12/26-12-03-21/
14-23-03-26/02-14-05-23/24-19-24-15/04-16-07-25/
18-01-07-4/19-22-09-18/7-19-10-02/23-16-01-21

9 5 5 HALF 4 5 HALF 7 4 7 9 7 4 5 7 HALF

The cipher reads left to right, top to bottom.
First transform numbers to letters using A=1, B=2, …, Z=26. The first 4 letters will transform into NINE but the rest is still garbled. Each set of 4 letters after the first is shifted 1 forward from the previous. You need to shift the 2nd set of 4 letters back 1 letter, the 3rd set back 2 letters, etc.

During the Cultist questline, in the microwave.

8 8 BRIMSTONE 8 8

Follow the guidebook to create a Cooler Rock, then put it in the microwave and cook it. Not sure if there’s a direct clue to solving this, maybe it’s just a reward for experimenting with everything in the Cultist area.

At one point in the Empyrean Questline you will go underground to a laundromat.

6 X 1 SMILE 2 HALF 4 9

The shirts in the washing machine have pictures of the keys you need to press on them. The large pause between shirts signals the start/end of the sequence.

In the punchcard machine during the Magpie questline

6 4 SMILE BRIMSTONE INFINITY X 9

The circles are aligned with a 4×4 grid that corresponds to the keys you need to press on the keypad. Follow the lines to a circle in the same order that your punchcard in the game is used: i.e. Column 1, top to bottom, Column 2, top to bottom, etc.

Interact with the Pistol in the Lawmakers questline.

1 2 8 2 9 9

When racking the slide to load the pistol you can see a number written on each bullet. The answer is just these numbers in order that they load into the gun. The ENTER symbol indicates the start/end of the sequence. You will need to refill the magazine to get the full sequence as it is longer than the capacity.

In the crew quarters where you sleep during the Lawmakers questline.

X 1 3 2 5 4

The symbol on the center of the locker is the key, the tally mark next to it is the order.

In the workshop area, left wall above the door to the parts shop.

1 5 2 3 6 4 7

Press the buttons corresponding to the Roman numerals in this order: closest to farthest from center, lowest to highest if same distance,

Far left side of the shop, near where you pay 1st and 3rd R. E. N. T.

INFINITY 4 1 1 4 INFINITY

ONE = 1, FOR = 4, ALL = INFINITY

Far left side of the shop, near where you pay 1st and 3rd R. E. N. T.

INFINITY SMILE HALF X SMILE BRIMSTONE

The squares match the colours of the buttons. Read top to bottom.

Go right from the sleeping area, on the front wall of the diner

1 2 4 7 5 3 X 6 8 HALF SMILE 9 INFINITY 6 3 5 4 SMILE

Overlay the image onto the keypad then press buttons along the four curves in order from one dot to four dots

In the Guidebook, near the back cover, visible under the blacklight in front of the parts shop.

1 3 4 7 2 5 1 4

The graph shows a plot of the Riemann zeta function ζ(0.5 + i*t) on the complex plane. It’s a pretty high-level but well-known mathematical function. You can read more on wikipedia: https://en.wikipedia.org/wiki/Riemann_zeta_function
The first non-trivial zero has an imaginary part approximately equal to 14.13472514, which matches the clue in the book with xx=14. The digits in square brackets form the answer.

During the Magpie questline, top floor of the warehouse.
