Cogwheel Puzzle Indiana Jones

Understanding Khmer Cogwheel Mechanics

Before diving into specific puzzles, here’s what you need to know about these ancient contraptions:

Two Types of Gears: Large cogwheels stay in their puzzle chambers, while small cogwheels can be carried between locations. There are 10 small cogwheels total throughout Sukhothai.

The Goal: Align all gears so everything rotates when you pull the lever in each room. Think of it like connecting a mechanical circuit—every gear must mesh properly with its neighbors.

Critical Rule: Never leave small cogwheels behind after completing a puzzle! You’ll need them for subsequent challenges.

Puzzle Locations and Solutions

Puzzles #1A & #1B: The Blessed Pearl

Your first encounter with these puzzles occurs during The Blessed Pearl main quest in northwestern Sukhothai. After swimming past the Yaek statue, you’ll find a chamber with a waterwheel and two mechanisms.

The right-side mechanism requires all three small gears you’ll find in this chamber—two on the floor and one on a ledge in the adjacent room. The left mechanism uses the same gears to open the stone gate revealing the Hidden Pyramid.

Puzzle #2: Waterfall Ruins

Located in western Sukhothai, this puzzle requires four small cogwheels. You’ll pick up another small gear here. Focus on positioning the large gears correctly before adding your small ones.

Puzzle #3: Wat Mahathat

This chamber sits on the same island as the large temple in the map’s center and needs five small cogwheels. The complexity increases here, so take your time visualizing how gears connect.

Puzzle #4: Wat Si Sawai

Found in the overworld area of Wat Si Sawai (not the underground section), this puzzle requires two large gears and six small parts to activate. You’re past the halfway point now!

Puzzle #5: Hidden Platform

Fast travel to Wat Chana Songkhram and ride the boat east. Look for an opening in the walls, dive, and use your Rebreather to access this challenge. Eight small gears are needed here.

Puzzle #6: Village

Like the previous puzzle, you’ll need the Rebreather to pass through an underwater opening. The solution forms an inverted-L shape from top to bottom using the smaller gears.

Puzzle #7: River Bank – The Final Challenge

This final puzzle requires all large gears in the room plus all 10 small parts you’ve collected. It’s the hardest of the bunch. Take your time—there’s no rush, and the reward is worth it!
