So, you’ve finally made it to "The Rook." It looks like your typical rundown Soviet-era manor—creaky floors, peeling wallpaper, and a basement that definitely smells like damp concrete and secrets. Most people treat the safehouse as a glorified menu where you just click on the mission board and upgrade your gear. Honestly? You’re leaving $1,000 and a pretty sick melee blueprint on the table if you do that.
The developers at Treyarch went full "escape room" with this one. Solving black ops 6 the rook secrets isn't just about finding a hidden room; it’s a multi-stage puzzle that forces you to actually pay attention to your surroundings. No quest markers. No hand-holding. Just you, a blacklight, and some very old-school spycraft.
The Boiler Room and That Annoying Piano
Before you can get to the good stuff, you’ve gotta deal with the plumbing. Literally. Most players wander around the piano room for twenty minutes wondering why the keys don't make sense. You can’t just smash buttons. First, head to the basement—not the secret one, the regular one.
Go through the door to the right of the briefing room. You’ll hear water hissing. There’s a note on the table that basically tells you the boiler is a ticking time bomb. To fix it (and unlock the path forward), you have to balance the fuel and the water.
- Turn the Boiler wheel twice to kill the water flow.
- Turn the Fuel wheel once to set it to half power.
- Flip the Pilot switch (you’ll see a little green light flick on).
- Turn the Boiler wheel twice again to get the water moving.
If you hear a distinct clunk, you did it. Now, go back upstairs to the piano room. Grab the blacklight off the table. If you shine it on the walls, you’ll see Cyrillic letters and numbers. Don't overthink the translation. The order is clearly marked: Ми (5), Pe (4), Cи (2), До (3), and Pe (4) again. Hit those keys in that order—5, 4, 2, 3, 4—and the wall next to the piano will slide open like a scene from a cheesy 70s thriller.

Hacking the "Keypadle"
Once you’re in that secret basement, you’ll hit a keypad. This is where people get frustrated because the code is randomized for every single person. You can't just Google "safehouse keypad code." It won't work.
Basically, it's Wordle with numbers. Pull out your blacklight and look at the keypad. You’ll see smudged fingerprints. The brightest ones are the numbers in your code. If a number is highlighted in green, it's the right digit in the right spot. Yellow means it’s in the code but in the wrong place.
Pro Tip: Look for "double" fingerprints. If a number looks extra smudged, it likely appears twice in your five-digit code.
After you crack that, you’ll find a computer. This part is a simple cipher. Match the numbers at the top with the letter key at the bottom. It always spells out words like BUNKER, HOLDING, ROOM, or OPEN. It’s the easiest part of the whole chain, honestly.

The Radio Puzzle: The Final Hurdle
This is the part that catches most people off guard. After you hack the computer and pick the lock on the nearby door (just rotate the pick until it glows white, standard stuff), you’ll find a radio. You need to tune the frequency and amplitude until the waves match.
Then, a voice starts talking. It sounds like a random Russian guy rambling about his day. Listen closely—or better yet, turn on subtitles. He’ll mention four specific items. Maybe it’s a couch, a purse, a calendar, and a flag. Or maybe it’s an iron, a curtain, a TV, and a cereal box.
These aren't just fluff. Use your blacklight to scan the room you're currently in. You’ll find numbers painted on or near those exact items.
- Found a "3" on the couch? That’s your first digit.
- A "1" on the purse? Second digit.
- You get the idea.
Once you have that four-digit sequence, sprint all the way back upstairs.

Claiming Your Rewards
Head to the second floor. There’s a bedroom at the end of the hall (Adler’s room). Tucked in the corner by the bed is a heavy safe. Punch in the code you just derived from the radio broadcast.
Inside, you’ll find $1,000 in cold hard cash. In the early game, that’s huge for upgrading your training area or weapons bench. You also get the Case Cracker melee blueprint and "The Puzzles, Mason" achievement.
It’s a bit of a trek, but honestly, it’s one of the most satisfying "non-combat" moments in the campaign. It makes the safehouse feel like a real place with a history, rather than just a lobby.
Actionable Next Steps:
- Grab the Blacklight first: You can't solve anything without it, and it's easy to walk right past it in the piano room.
- Toggle Subtitles: The radio message can be hard to hear over the game's ambient noise; subtitles make identifying the four keywords foolproof.
- Invest the Cash Immediately: Don't sit on that $1,000. Go straight to the gear station or weapons bench to give yourself an edge in the next mission.
- Check the Walls: Beyond the puzzles, the blacklight reveals footprints and hidden notes that flesh out the lore of what happened in the house before your team moved in.
