- Indiana Jones and the Great Circle chest code values are often hidden within environmental clues like notes, calendars, or statues.
- Adventure Books found inside safes are essential for unlocking new skills like "Splinter Smash" or "Street Scrapper."
- Disguises such as the Wehrmacht Uniform are required to access restricted areas containing high-tier loot.
- Currency rewards vary by region, providing Lira in the Vatican, Egyptian Pounds in Gizeh, and Baht in Sukhothai.
- Explosive Traps exist; specifically, the "Bright Future" chest in Gizeh contains dynamite instead of treasure.
Vatican City: Safe Locations and Combinations
Vatican City serves as the first major open-world hub where players encounter complex lockboxes. Finding an Indiana Jones and the Great Circle chest code in this region usually requires keen observation of your surroundings. Clues are rarely handed to you; instead, they are tucked away in desk drawers or encoded in planetary charts.
Video Highlights:
- Detailed walkthrough for the Belvedere Courtyard Ticket Stub puzzle.
- How to solve the "Secret of Secrets" planetary alignment in the Sistine Chapel.
- Locating the hidden Blackshirt guard carrying the Post Office Cellar note.
- Using blacklight/lamp mechanics to reveal the Museum Wing safe code.
The Vatican safes are diverse, ranging from military ration crates to traditional heavy iron safes. Below is the full breakdown of codes for this region:
| Location | Associated Mystery | Code | Primary Reward |
|---|---|---|---|
| Belvedere Courtyard | The Stolen Cat Mummy | 5238 | Splinter Smash Skill Book |
| Sistine Chapel | Secret of Secrets | 4471 | Cutman 1 Skill Book |
| Post Office Cellar | A Savage Discovery | 1136 | Street Scrapper 1 Book |
| Museum Wing (Tent) | A Date to Remember | 6380 | Vatican Medicine Map |
| Borgia Tower | Father and Son | 5873 | 100 Adventure Points |
| Museum Wing (Safe) | A Nun in Trouble | 7171 | Lost Artifact (Drinking Horn) |
| Excavation Site | Signs of Trouble | 1891 | 100 Adventure Points |
For the "A Date to Remember" chest, don't be fooled by the "4718" code mentioned in the notes. That code was for a Wednesday. Since the shipment actually arrived on a Friday, you must use the Friday column on the calendar, resulting in 6380.
Gizeh: Egyptian Hieroglyphs and Nazi Compounds
In Gizeh, the puzzles shift from religious iconography to archaeological ciphers and military intelligence. Finding the Indiana Jones and the Great Circle chest code for the Nazi Office, for instance, requires understanding how to read hieroglyphic number bases.
Video Highlights:
- Solving the Egyptian numeral code in the small house near Khentkawes.
- Cross-referencing weather reports and cloud atlases for the Meteorological Station.
- Infiltrating the Nazi Compound to find the 5-digit safe code.
- A warning regarding the trapped "Bright Future" chest.
Gizeh features several high-value targets, including the Nazi Compound which houses a massive gold bar.
| Location | Clue Type | Code | Reward |
|---|---|---|---|
| Nazi Vehicle Garage | Code Letter in Garage | 0805 | Harvest Stele |
| Weather Station | Cloud Atlas/Logbook | 0609 | Gizeh Medicine Book |
| Khentkawes Digsite | Hieroglyphic Bases | 3262 | Ancient Relic / Currency |
| Nazi Compound | Command Center Note | 40926 | Gold Bar / Luger Pistol |
| Vehicle Depot | Nazi Thief's Note | 0926 | Dynamite (Trap) |
| Rock Conveyor | Winning Card Hand | 13218 | 100 Egyptian Pounds |
The chest located near the wagon between the Worker Camp and Khentkawes (Code: 0926) is a trap. It contains lit dynamite. Open it only if you want to complete the "Bright Future" mystery, and be prepared to dodge immediately.
Himalayas: The Kummetz Cipher Machine
The Himalayas section features a unique mechanical puzzle rather than a standard chest. To progress through the main story in Kummetz, you must unlock a sealed door in the Officer Lounge using a cipher machine. This is the only mandatory Indiana Jones and the Great Circle chest code required for story completion in this region.
Locate the Captain's Code
Find the clipboard in the lounge with the letters JÖGM. This is your encrypted key.
Collect the Code Wheels
Gather the four metal discs scattered around the room. Each disc contains a unique set of letters.
Configure the Cipher Machine
Insert the wheels into the machine. Wheel 1 has 'J', Wheel 2 has 'Ö', Wheel 3 has 'G', and Wheel 4 has 'M'.
Extract the Password
Spin the handle to align JÖGM. The machine will reveal the decrypted word: BLUT.
Consult the Table
Check the lookup table on the table. The word BLUT corresponds to the numeric code 3666.
Entering 3666 on the keypad will unlock the heavy door, allowing Indy to proceed toward the mountain peak.
Sukhothai: Board Games and Tiger Paths
The final region, Sukhothai, combines traditional combat with intellectual challenges like the Mak-Yek board game. Many players struggle with the Indiana Jones and the Great Circle chest code here because the clues are integrated into the environment's mini-games.
Voss' Camp Strategy
- Infiltration: Use the rebel tunnel under the eastern side of the camp.
- Rewards: The safe in Voss' office contains 2,000 Baht (four gold bars).
- Code: Found on the officer guarding the room (5484).
A Game of Wits
- Puzzle: Solve the Mak-Yek board game by moving four blue pieces.
- Logic: The code is derived from the row numbers where your pieces end.
- Code: Use 3186 to unlock the nearby stash.
| Location | Mystery Name | Code | Reward |
|---|---|---|---|
| Tongdang's Hut | Path of Tigers | 2480 | Jumbo Grip Skill Book |
| Voss' Camp | Voss' Gold Stash | 5484 | 2,000 Baht |
| Voss' Camp | A Game of Wits | 3186 | 250 Adventure Points |
| Wat Chana Songkhram | Timely Arrival | 59404 | Sukhothai Medicine Map |
| Wat Mahathat | Counting Letters | 4134 | Street Scrapper 3 Book |
To find the code for the Path of Tigers (2480), you must travel to the Wat Si Sawai ruin in the south. Look for a large Buddha statue; the code is scrawled inside a tiger paw drawing nearby.
Exploration Checklist
To maximize your efficiency in Indiana Jones and the Great Circle, ensure you have collected all essential items from these locked containers.
Essential Safe Rewards:
- Splinter Smash Book (Vatican - Belvedere)
- Street Scrapper 1 Book (Vatican - Post Office)
- Gizeh Medicine Map (Gizeh - Weather Station)
- Drinking Horn Artifact (Vatican - Museum)
- Jumbo Grip Book (Sukhothai - Tongdang's Hut)

Always prioritize safes containing Adventure Books. These books unlock permanent upgrades to Indy's combat and stealth abilities, which are far more valuable than the currency found in standard chests.
Frequently Asked Questions
Q: Why does the Indiana Jones and the Great Circle chest code not work sometimes?
Ensure you are at the correct chest. Many regions have multiple 'Nazi Ration Chests' that look identical. Also, check if the code is 4 digits or 5 digits, as some endgame safes require longer combinations.
Q: Can I go back to get a code I missed?
Yes. You can use the 'Travels' page in your journal to 'Revisit' any region. All safes remain in their original state until opened, even after the main story is finished.
Q: What is the best reward found in a safe?
The Skill Books are the best rewards. For example, 'Splinter Smash' allows you to break through wooden barriers, and 'Street Scrapper' significantly improves Indy's melee damage.
Q: Do I need a special tool to open safes?
No, you only need the correct numeric combination. However, some chests are behind locked doors that require specific keys, like Juliana's Key or the Wehrmacht Key.
