Hydropuzzle: Walkthrough Guide

By: Przemyslaw Sobstel


This is a complete walkthrough guide with help, hints tips, tricks, solutions and answers for the iOS and Android puzzle game, Hydropuzzle, by Przemyslaw Sobstel. Feel free to ask for extra help in the comments section.


Chapter 1, Summer Heat:

To get the password, translate the rest of the message. Each symbol represents a different letter, and the game tells you the password made of symbols.

Password: QWERTY


Chapter 2, Men in Black:

Passcode: 3295

Chapter 3, Up Up and Away:

For this puzzle, press the lock to see a tweet with a clue. It says “hexy number #FF.”

It’s telling you to turn FF into hexadecimals.


CVV: 255

Chapter 4, Alcohol is Evil:

There are 16 photos, each with a number on them. There are also 16 railroad pieces. The numbers on each photo tell you which piece it’s giving you the answer for. So, let’s use the first one as an example. It has the number 24 on it, or (2,4). So go 2 across and 4 down and change that piece to a straight vertical line to match the arrow in the photo. Then do the same for all the other photos, looking for a shape that matches a track piece. The Morse code on 34 says UP! It should look like this in the end:


Chapter 5, Vile Vicious Villains:

Press the right button to use the Password Sniffer to hack the WiFi password. Some dots under numbers start flashing. It’s says:

Hacked by algorithm.

If you google “letum myth,” you get stuff about Mors, which is supposed to be a hint to use Morse code to decipher the blinking dots.

Pay attention to each number individually and write down short blinks and long ones as dots and dashes. You get:

1: Γò¼├┤Γö£├ºΓö£Γöé–Γò¼├┤Γö£├ºΓö£Γöé = P
2: ΓÇóΓÇóΓÇó = S
3: ΓÇóΓÇóΓÇó = S
4: Γò¼├┤Γö£├ºΓö£Γöé– = W
5: ΓÇó-ΓÇó = R
6: -ΓÇóΓÇó = D

The answer is: PSSWRD

Chapter 6, Crocodile Tears (Apart):

The deactivation code is STOP, but you need to write it out using numbers.

S = 19
T = 20
O = 15
P = 16

So you need to use Brainf*ck to program it to get those numbers and I really don’t have the head for that. Anyway, apparently there are multiple answers with this being one of them:



You need to push the right button after to destroy the nuclear reactor. But if you mess up, you can just rewind time, so don’t worry.

Chapter 7, Afterparty:

Use the arrows to cycle through numbers and letters. When you see the sun, note down the letter and number. So you get this:

1 T
2 H
3 E
4 _
5 E
6 N
7 D

Solution: THE END

Credits (Bonus Puzzle with Keyboard):

Eliminate the keys with X’s on them. I’m not sure what else to do here.

    CVV is the hexadecimal number FF, or 255.

    The pattern in the routing puzzle is symmetrical, which will Help with some of the ambiguous clues (like the LOGO one). The graph one is e^x, so left then up.

    Stuck on the next puzzle. Letum is another word for Mors, the god of Death, but I canΓÇÖt turn the lights into Morse code and donΓÇÖt see where else to turn.

      Lights are the Morse code. You just need to go one by one (they don’t start at the same moment). It’s important to notice difference between long break, short break, short signal and long signal… it actually follows actual Morse code spec.

  2. Lauren

    CVV code in chapter 3 is 255.

    Letters left are an anagram of Thank You but I cant see how the numbers relate.

      Numbers tell the order of letters.

      1. Miguel

        It does not make sense. If you put by that order, it means nothing.
        What does it mean to you?

          The first row of the keyboard is left with “TYUO” which corresponds to the first row of letters “1798”. Now do the same with each row of letters and numbers. You will get T-1, Y-7, U-9, O-8, A-3, H-2, K-5, N-4, and finally, the last number “6” corresponds to the space bar. Organize these letters (and the space) by the numbers, and you will get “THANK YOU”
