You’re freezing. Literally. In the middle of the Himalayas, Indy finds himself aboard the KMS Kummetz, a German battleship that has no business being stuck in a mountain range. It’s one of the best atmosphere-heavy levels in Indiana Jones and the Great Circle, but it also features one of the most notorious head-scratchers in the game: the indiana jones captains code.
Honestly, it isn't even that the puzzle is "hard" in a traditional logic sense. It’s just that it requires you to juggle three different pieces of paper and a physical machine, and if you miss one detail, you're stuck staring at a locked door while the wind howls outside.
If you just want the number to get moving, it's 3666.

But if you actually want to understand how the heck you were supposed to get there—or if you're stuck because the wheels won't turn—let's break down exactly what happened in that Officer Lounge.
The Kummetz Cipher: How the Captains Code Actually Works
The whole mission, "A Harsh Climb," leads you into the Officer Lounge. It’s a grim scene. Everyone is frozen solid. You need to get into the Captain's Quarters to find that stone fragment, but the door is electronically locked.
To find the code, you have to use the Kummetz Cipher Machine sitting in the corner. Most players find the "Captain’s Code" note first. It's a clipboard on the central table with a bunch of four-letter words crossed out. Only one isn't: JÖGM.
Here’s the catch. JÖGM isn't the door code. It’s the key to the cipher.
Step 1: Hunting for the Wheels
You can't just walk up and type. The machine is missing its internal discs. You have to find four Code Wheels scattered around the room. They’re usually right there on the floor or the nearby counters, but in the low light of the blizzard, they’re easy to overlook.
Step 2: The Logic of the Slots
This is where people get annoyed. You can't just shove the wheels in anywhere. Each wheel has a specific set of letters, and they correspond to the positions of the JÖGM code.
- Slot 1: Needs the wheel containing the letter J.
- Slot 2: Needs the wheel with the Ö (the one with the two dots).
- Slot 3: Needs the wheel with G.
- Slot 4: Needs the wheel with M.
If you put them in the wrong order, the machine won't give you the right translation. Once they’re in, you close the lid and rotate the dials until the top row spells out JÖGM.
Step 3: From Letters to Numbers
Once JÖGM is aligned, look at the row of letters directly below it. It spells out a new word: BLUT.
In German, that means "Blood." Creepy, but thematic for a ghost ship. Now, go back to the central table and look for a different document—the Code Table. This is basically a legend or a manifest. You’ll see a list of words like "EIS," "WOLF," and "BLUT," each with a four-digit number next to it.
Find BLUT, and you’ll see the sequence 3666.
Why the Indiana Jones Captains Code is a Masterclass in Game Design
MachineGames didn't just throw this in to pad the runtime. This puzzle is a direct nod to the Enigma machines of the era. It forces you to play like an archaeologist—not just a guy with a whip. You have to observe, collect, and synthesize.
I’ve seen people complain that the game doesn't "hold your hand" enough here. If you use Indy’s camera to take a photo of the documents, he’ll usually mutter a hint to point you in the right direction. It’s a great way to keep the immersion without breaking the "expert" vibe of the character.
There's also a subtle bit of environmental storytelling here. The fact that the code is "Blood" and the crew is frozen in their final moments suggests the Captain was a bit... intense.
Common Mistakes (And How to Fix Them)
If the door still won't open after you've put in 3666, check these three things:

- The Umlaut: Make sure you’re using the Ö and not just an O. It matters.
- The Order: Double-check that you didn't swap the third and fourth wheels. The "G" and "M" wheels look similar if you're rushing.
- The Document: Some players try to find JÖGM on the number table. It’s not there. You must translate it to BLUT first.
Actionable Next Steps for Players
- Scavenge the Floor: Before interacting with the machine, do a full sweep of the room for all four wheels. One is often tucked behind a chair.
- Use the Camera: If you're playing on a higher puzzle difficulty, the hints are fewer. Take a photo of the "Code Table" so you can reference the numbers without walking back and forth to the table.
- Check the Journal: Your journal stores every document you find. If you accidentally clicked past the Captain's Code note, just hit the journal button to see the JÖGM letters again.
- Prepare for a Fight: Once you open that door and grab the stone, things get loud. Make sure your revolver is loaded before you step through.
The indiana jones captains code is a hurdle, but once you understand the "Word -> Cipher -> Table" flow, it’s incredibly satisfying to hear that heavy metal door finally click open.
