Indiana Jones and the Great Circle codes list for the Vatican, Gizeh, and Himalayas

Codes are the key to many mysteries in Indiana Jones and the Great Circle. You’ll need these codes to unlock the various safes and chests (and at least one door) found throughout the game.

As you explore, you’ll find locked safes and chests throughout the game. In most cases, the code to unlock the safe or chest is associated with a mystery (what the Great Circle calls its side quests). Throughout these side quests, you’ll find notes, which give you hints as to what the code could be — or you could just use this guide.

In this in-progress Indiana Jones and the Great Circle guide, we’ll run down all codes we’ve found so far, and where applicable, listed the mystery associated with it.

Indiana Jones and the Great Circle codes, explained

Most chests and safes reward money or Adventure Points (XP, basically), but they also contain things like adventure books (which grant you access to new skills) or hidden relics associated with collect-’em-all side quests.

Below, see a running list for all codes we’ve found so far in Indiana Jones and the Great Circle, plus details about where to find them and what rewards you get for opening them. We’ve also listed the mystery that’s either associated with the safe, or the one you’ll play through when coming across it for the first time. That said, since the Great Circle’s levels are so open-ended, you might come across these under other circumstances.

For more details about how to find some of these codes, we’ve included guides to some of the more involved side quests below. And if you’ve missed any of these safes or chests, you can return to previously explored locations by opening your journal, tabbing over to the “Travels” page, and selecting “Revisit” on the region you want to go back to.
