All puzzles in the Rook house in Call of Duty: Black Ops 6 — how to solve them

Puzzles in Call of Duty: Black Ops 6 are an integral part of the gameplay, adding elements of strategy and analysis. When you find yourself in the safe house, you will encounter various puzzles that will require your attention and logical thinking. In this guide, we will detail each puzzle, providing a step-by-step walkthrough so that you can easily handle any challenges and successfully progress through the story.

A detailed explanation of the piano puzzle can be found in a separate guide.

In the Notes section, you will learn that there is a locked safe on the upper floor. To open it, you will need a four-digit code. To obtain the necessary numbers, you will have to solve several mini-puzzles throughout the mansion — we will describe this below.

If you just want to open the safe and get the money, try entering these codes; one of them will definitely work:

To get to the basement, head to the corridor located to the right of the briefing room. Here you will find a door, open it and go down the stairs. To restore power to the hidden part of the house, you need to solve the boiler puzzle.

By studying two notes, you will get a hint for solving this part of the puzzle. The left button controls the gas. The middle button controls the water. The right button turns on the igniter:

Thanks to these actions, you will open another door near the piano.

Inside the underground corridor, enter the door on the right. There is a cipher journal hanging on it. To open it, use the Blacklight flashlight and enter a random combination of numbers. Since the code is different for each player, your task is to find the correct password.

If you see green numbers, it means that you not only guessed part of the code but also placed the numbers in the correct positions. If a yellow number appears, it means that you guessed its value, but it should be in a different position. Immediately cross out all red numbers from the code combination and do not use them again.

Inside the opened room, read the note, and at the end of the room, find the cipher machine.

Your task is to select four correct words. These words are always relevant:

The order of entering the words will vary, so you need to carefully follow the given code. At the bottom, you will find the connection between the numbers and letters, and in the upper left corner, the encoded word in numerical format is indicated.

After entering the correct word, you will see one of the two basement doors open. Enter and go to the right to the end of the corridor, where you will find a room. On the table in this room lies a note stating that to access the room and obtain the key, you need to pick the lock using a lockpick.

To do this, simply rotate the lockpick by moving the game mouse until you see the spring light up. Hold it in this position for a few seconds. Repeat these actions for the remaining two springs to successfully open the lock.

Follow the sound signal coming from the adjacent room to locate the radio. It is positioned to the left of the TV.

By interacting with this device, you can control the amplitude and frequency of one of the waves. Your task is to make it match the second wave. First, increase the amplitude so that the top and bottom parts of the waveforms align, creating a harmonious match. Then adjust the frequency to match the width of the other wave. Once you successfully complete these adjustments, the radio will start playing an audio message.

The message coming from the radio is unique for each player, so unfortunately, we cannot provide a universal answer. However, we can explain how it works.

The received message talks about four items that you will need to find. By turning on the black light, you should illuminate these items to discover hidden symbols on them. Be attentive and thoroughly inspect each one — these signs will help you unlock the safe.
