Solving the Indiana Jones Code Puzzles

The solution to the Cipher Machine puzzle is 3666. Below are the steps you can follow in *Indiana Jones and the Great Circle* to arrive at this answer independently.

Once you enter the Officer Lounge, locate the necessary items: The Captain’s Code, two Code Lists, the cipher machine, and four code wheels marked with letters—none of which are inside the machine. Your first task is to prepare the cipher machine before you work on cracking the code. Don’t fall into the trap I did by trying to solve everything via manual code tables; it’s much simpler than that!

Close the cipher machine’s lid and adjust the wheels to spell “JÖGM” in the top row, making sure the white triangles align with each letter. This will result in the bottom row displaying “BLUT.”

Take a look at the Code Table located on the table behind you. Here, you’ll discover that the four-digit code for “BLUT” is 3666.
Head to the exit door and input the code. The door will open, allowing you to climb up the ladder and reach the battleship’s bridge.
