Indiana Jones And The Great Circle - Khmer Cogwheel Puzzles Guide

Sukhothai's rivers and jungles are what you'll explore later in the Indiana Jones and the Great Circle campaign. Once there, you also have to solve several tricky challenges left behind by the people of the Khmer Empire. Here's our guide on how to complete all Khmer Cogwheel Puzzles in Indiana Jones and the Great Circle.

How to solve all Khmer Cogwheel Puzzles in Indiana Jones and the Great Circle - Puzzle guide

The Indiana Jones and the Great Circle Khmer Cogwheel Puzzles can be found all over the Sukhothai region. We've organized our guide to start out with a few basic tips, followed by the locations of these brain teasers. Note that these tend to reward you with Sukhothai Relics, which are needed if you want to unlock the game's secret ending.

The Khmer Cogwheel Puzzles in Indiana Jones and the Great Circle all involve the use of gears, which you need to place on a diagram to activate machinery. Here are a few tips:

• Puzzle diagrams consist of large cogwheels, which you leave behind in their respective puzzle chambers, and small cogwheels, which you get to bring along to other areas. There are 10 of these small cogwheels in total.
• The goal of each puzzle is to align all gears so that everything rotates and moves when you pull the lever in the room. Doing so nets you a Sukhothai Relic as a reward (except for the first area).
• Don't leave behind small cogwheels when you're done with a puzzle, since you still need them for later.
• You may also purchase the Sukhothai Cogwheels booklet from Tongdang, which costs 700 baht.
• Lastly, you can find pillars outside these puzzle rooms. Take pictures of these to earn Adventure Points.

The map above shows the Indiana Jones and the Great Circle Khmer Cogwheels. We've numbered them accordingly based on how many small gears are required to fully activate the mechanism in each area. Moreover, the seventh and last location isn't marked on the map, even while tracking the quest, as it's meant to be the last challenge.

Note: There are alternate methods to solve each chamber's puzzle. However, we've encircled the spots where we placed the small gears so you have an idea of how we completed each part.

The first Khmer Cogwheel Puzzle that you encounter is actually part of The Blessed Pearl main quest, which takes place in the northwestern portion of the map. After swimming underwater past the Yaek statue, you'll find yourself in a chamber with a waterwheel and two mechanisms.

There are two small gears on the floor, and the third is on a ledge in the adjacent room. In any case, the mechanism to your right requires all three small gears, as well as the large gears in the room.

The image above is for the mechanism on your left. As usual, you need the large and small gears. When you're done, the stone gate should open, revealing the Hidden Pyramid just beyond. Don't forget to grab the small gears that you just used.

Located in the western part of Sukhothai. You can pick up another small gear in this room. You only need four at this point, though you still need to place the larger gears in the correct spots.

This particular chamber is on the same island as the large temple in the center of the map. You need five small cogwheels for this trial.

This Khmer Cogwheel in Indiana Jones and the Great Circle is in the overworld area of Wat Si Sawai. As such, you won't need to head to the underground area, which is part of the Kid Who Vanished side quest.

In any case, you just need to place two large gears and six of the small parts to activate the machine.

Fast travel to Wat Chana Songkhram and ride the boat to the east. When you see an opening in the walls, dive and use the Rebreather so you can access this next challenge.

Similar to the previous trial, you also need to use the Rebreather to pass through the underwater opening. As for the diagram itself, you mostly just form an inverted-L shape from top to bottom using the smaller gears.

Once you've finished the previous challenges, the River Bank chamber should get tracked on your map. This one tends to be the hardest since it requires the large gears in the room and all 10 small parts you've collected.

In any case, you should be done with all Khmer Cogwheel Puzzles in Indiana Jones and the Great Circle. This whole endeavor nets you an additional six relics, though there are more to obtain as you explore the region. You can learn about these in our Sukhothai Relics guide.
