The Indiana Jones and the Great Circle cog wheel puzzle in Khmer is part of the Blessed Pearl quest, in which the player has to set up a series of cogs to set an old mechanism working again. The puzzle itself is split into two parts - locating the cogs around Khmer accordingly, then setting them up in place to let the water flow through again.
It's a tough challenge, but also serves as a little practice puzzle for an optional side quest based on cogs found around the region for those seeking further completion. If you want a hand on understanding how to solve the cog puzzle in Indiana Jones below, we've got the solution all laid out accordingly.
All Indiana Jones and the Great Circle cog locations
There are four Khmer cogwheels in the main chamber to use - two small and two large. There's also another small cog behind the Left Gear Train on a small ledge I've highlighted above. You should find it when you investigate the need for water as it's on the platform you need to reach to whip yank the pipe open to start the water flow.
That gives you a grand total of three small cogs and two large ones for this Indiana Jones and the Great Circle conundrum.
Just remember to get the water flowing over the wheel behind the Left Gear Train or you won't be able solve that puzzle when the time comes.
How to solve the Cog wheel puzzle in Indiana Jones and the Great Circle
Above is the solution for the Right Gear Chain in Indiana Jones. You need all three small cogs and one large one to connect the central cog to the one on the right. When you have it all placed correctly, pulling the lever will make the two monster statues drop into the floor. Once that's happened the puzzle is solved and you can take the cogs off to use on the left hand side.
Next we cover the solution for the Left Gear Train in Indiana Jones. You'll need all the cogs you've found - two large and three small - to complete this one and connect the central cog with the destination cog on the left hand side. Again, when you get it right the two monster statues will sink into the floor to let you know it has been completed. If you haven't done the right hand side at this point you can now strip the cogs to use them there.
How to open the hidden gate in Indiana Jones
Once both the gear trains have been solved and the cog mechanisms have done their job all that's left to do it turn the wheel that is highlighted. That will open the hidden gate, letting Indy and Gina carry on and see what's on the other side.
