At the heart of the Wat Mahathat fascist camp in Sukhothai, you’ll come across a makeshift tent decked out with various tables, including one that’s home to a large locked chest. Unfortunately, you can simply yank it open as it has a lock that requires a four digit code.

Next to the chest you’ll find a cipher machine along with several lettered reels and documents – all clues to cracking the code and getting to the bottom of the Counting Letter mystery. It’s similar to the cipher puzzle onboard the Kummetz in the Himalayas. In this guide, we’ll walk you through how to get the Counting Letters code in Indiana Jones and the Great Circle.

Counting Letters cipher code solution

The code to unlock the Counting Letters chest is 4134. To get the code, you’ll first need to pick up the Bartolomeo’s Challenge document sitting next to the chest. It details a game between two soldiers – Lorenzo and Bartolomeo – who keep one upping each other with increasingly complex puzzles, including one tied to the A Game of Wits chest over in Voss’ Camp in the north of Sukhothai. In the letter, Bartolomeo gives a single clue: the code JHHS.

Next, you’ll want to pick up the four code wheels and place them in the correct order in the cipher machine, but looking at them, you’ll notice that only three out of the four have the letters required to spell out JHHS. Place them on the cipher machine in the following order, starting from the left-most slot:

  • Slot 1 – C-D-O-A-J-B-S-R
  • Slot 2 – A-H-I-G-U-V-Z-Q
  • Slot 3 – U-F-H-E-K-T-O-L

Turn each of the wheels to spell out JHH then pull the machine cover down and note the letters on the row below – BIE. For the final letter, take out the C-D-O-A-J-B-S-R wheel from the first slot and place it in the fourth. Pull the machine cover down again and note the final letter in the row below – R. This gives us the word BIER.

Pick up the Code Table document immediately right of the cipher machine and find the word BIER. Alongside it is the code 4134. Head over to the chest and dial in the code to open it. Inside, you’ll find 75 Baht and the Street Scrapper III Adventure Book, which increases the damage Indy deals with one and two-handed melee weapons. Opening the chest also wraps up the Counting Letters mystery.
