You’re freezing your tail off in the Himalayas, surrounded by frozen Nazis in an officer’s mess hall, and there’s a locked door standing between you and the rest of the story. Typical Indy. Indiana Jones and the Great Circle loves to throw these environmental roadblocks at you, but the Captain's Code (officially part of the Kummetz Cipher puzzle) is one of those moments where the game stops being a brawler and starts being a genuine head-scratcher.
If you’re staring at a bunch of metal discs and a confusing clipboard, don't worry. It’s not as complicated as it looks once you realize the game is playing a bit of a trick on you. You aren’t looking for one code; you’re looking for a keyword that unlocks a number.
Finding the Hidden Letters
Most people get stuck because they find the "Captain’s Code" document and see the letters J-Ö-G-M. Naturally, you think that’s the password. It’s not. It’s just the "key" to the cipher machine.
First, you need to scavenge the room. There are four code wheels (metal discs) scattered around the officer’s quarters and the mess hall. They aren't hidden behind secret walls or anything—you’ll find them on tables and the floor. Grab all four.
Once you have the wheels, head to the cipher machine (the Code Table) on the furniture in the cabin. This is where the actual legwork happens. You have to insert the discs into the machine in a specific order to spell out that J-Ö-G-M sequence.
- Slot 1: The disc with "J"
- Slot 2: The disc with "Ö" (look for the dots!)
- Slot 3: The disc with "G"
- Slot 4: The disc with "M"
The Real Indiana Jones and the Great Circle Captains Code
Here is the part that trips everyone up. After you’ve slotted the wheels and dialed in J-Ö-G-M, the door doesn't just magically pop open. This is a cipher, after all.
Look at the row of letters directly below the ones you just entered.
If you’ve set the wheels correctly, the letters underneath J-Ö-G-M should spell out B-L-U-T. In German, that means "blood," which fits the slightly macabre vibe of a ship full of frozen corpses.
Now, take your eyes off the machine and look at the clipboards and documents sitting on the nearby tables. One of these papers acts as a translation key. Find the word BLUT on that list. Next to it, you’ll see a four-digit number.
The actual code to unlock the Captain’s door is 3666.

Why This Puzzle Is a "Love It or Hate It" Moment
Honestly, the feedback on this specific puzzle has been all over the place since the game launched. Some players feel it’s the perfect "professor" moment for Indy—using his brain instead of his whip. Others, like some frustrated folks on Steam and Reddit, found it a bit obtuse because the game doesn't explicitly tell you to look under the primary code for the solution.
One common frustration is the "camera" mechanic. If you’re playing on higher puzzle difficulties, you don’t get the helpful UI highlights. You actually have to pull out your camera and photograph the documents to get Indy to jot the clues down in his journal. If you haven't photographed the code list, you might find yourself staring at "BLUT" without any idea what the numbers are.

Quick Fixes for Common Issues
- Can't find a disc? Check the floor near the uniforms. One of them usually rolls off the table.
- The code 3666 isn't working? Make sure you're at the right door. This is for the metal door in the Himalayas "A Harsh Climb" mission.
- Is the "Ö" missing? Make sure you didn't pick up a "O" by mistake. The umlaut matters for the cipher to align correctly.
Practical Steps for Your Next Move
Once you’re through that door, the game picks up the pace again. You’ll be heading toward a secret passage that leads out of the safe room, finally getting you out of the cold.
If you want to stay ahead of the curve for the rest of the Himalayas, keep your camera out. This level is dense with "Fieldwork" opportunities that earn you Adventure Points. These points are basically the currency for Indy's upgrades, like "True Grit" (which lets you survive a fatal blow).
Specifically, look for the frozen crew members and unique Nazi equipment. Snapping photos of these won't help you open doors, but it’ll make Indy a lot tougher for the fights coming up in the later Sukhothai sections. Just remember: in this game, your brain is usually a better weapon than your revolver.
Actionable Insight: Before leaving the room, check the desk one last time for any loose "Intel" items. These small collectibles are easy to miss when you're rushing to punch in a code, but they are essential for hitting 100% completion in the Himalayas region.
