During your Indiana Jones and the Great Circle adventure in the Himalayas chapter, you’ll encounter a particularly challenging cryptographic puzzle aboard an abandoned vessel. This brain-teaser emerges as part of the “A Harsh Climb” main mission sequence, presenting a significant obstacle that many players find initially perplexing.
The puzzle unfolds within an officer’s dining area where the crew has met a frigid fate. To advance through this section, you must decipher an encoded mechanism that guards a sealed metal doorway. The solution requires careful observation and methodical clue collection from the surrounding environment.
Your primary evidence originates from the Captain’s Code document discovered within the chamber. This crucial paper displays a specific letter sequence: J-Ö-G-M. Understanding this coded message is fundamental to solving the entire puzzle mechanism.
The inclusion of the “Ö” character with its umlaut diacritic is particularly noteworthy. Many players mistakenly search for a standard “O” character, which leads to incorrect solutions. The game deliberately uses this distinctive character to emphasize the puzzle’s cryptographic nature.
Additionally, you’ll find two supplementary Code Table documents in the immediate vicinity. These provide contextual support but aren’t immediately essential for the core solution process.
Scattered throughout the mess hall are several physical Code Tables—circular disks inscribed with individual letters. These interactive objects are located on various surfaces including countertops and the floor. Your objective is to gather all required disks and install them into the cipher device in the precise sequence indicated by the Captain’s Code.
- Initial position: Select the disk marked with the letter “J”
- Second position: Locate the disk featuring “Ö” (note the umlaut distinction)
- Third position: Identify the disk containing the letter “G”
- Final position: Position the disk displaying “M”


Systematic searching is crucial as some disks may be partially obscured by environmental details or positioned in shadowed areas that make them easy to overlook during casual exploration.
Seasoned puzzle solvers recommend conducting a thorough room sweep before attempting any disk placement. This prevents the frustration of incomplete solutions and ensures you have all necessary components before engaging with the cipher mechanism.


Common errors include misreading the umlaut character as a standard O, placing disks out of sequence, or failing to locate all four required components. The puzzle typically takes 5-10 minutes to complete once you understand the core mechanics.
