Room three puzzles
The third room has a desert theme, with a box in the center, plus a lamp, a knife, and a lantern around it. Pick up the Oil Lamp and pull the Knife from the ground to add them to your inventory.

Knife puzzle
Open the Knife in your inventory. Press the black button on it to get a key.

Slider and symbol-matching puzzle
Begin with this slider puzzle on the side of the box.

Move both sliders to the top to open up the bottom panel.

Move both sliders to the bottom to unlock the top panel and reveal a symbol-matching puzzle.

The goal of this puzzle is to fill each row with pieces containing the symbol on either end of it. The blue buttons in the row swap the pieces they are between horizontally, while the blue buttons outside of the rows swap the pieces between them vertically. I found that the easiest way to do this puzzle was to fill in the top row corners first, then the top row centerpieces, and repeat this process on the middle and bottom rows.

Completing the matching puzzle will pour out two piles of treasure. One contains a Scorpion Figure while the other contains a Coin.

Scorpion roof puzzle
This purple roof puzzle has a hexagon space in its center.

Looking at the Scorpion Figure in your inventory reveals a hexagon peg on its stomach. Place it here and slide it upwards to unlock a gear.

Spin the gear to open the top of the box, which contains a Metal Ring.

Lantern lock puzzle
The Key from the Knife can be placed into the lantern's lock.

Rotate it and open the lantern door to get a Lit Candle.

Front gravity puzzle
Focus on the red ball at the front of the box.

Place the Metal Ring around it to reveal a gravity puzzle.

The gear at the start needs to be moved to the center by rotating the puzzle so that it falls down the path.

The tricky part comes when you're ready to push it towards the center, but the blue mobile pathway is still at the start. To get past this section, start by dropping the gear as far down as it can go.

Then, rotate the puzzle so that the pathway falls into place. The gear should be held in place by the nearby wall.

Now the gear can be moved easily into the center of the puzzle.

This will unlock the box, transforming it into a temple-like structure.

Circular platform puzzle
Focus on the circular platform in front of the mask.

Rotate it so that the blue triangles are on the left and right.

Place the Coin on top of it to open up the section.

Use the Oil Lamp to fill the container with oil.

Light the oil with the Lit Candle.

Tiny statue puzzle
Lighting the fire opens up a hallway behind the mask and displays a tiny statue on a toothed platform. This puzzle is unlike any other in the game, acting as an intense game of red light, green light.

Hold the left mouse button on the statue to help him walk down the hallway.

When the mask flips and turns red, stop moving. If you don't, you'll be smashed to pieces and have to restart the puzzle. The easiest way to avoid this fate is to let go as soon as the spin is halfway through.

Completing this puzzle gives you a Model Tower and returns you to the main room. The fourth room will now be unlocked.

Room four puzzles
The fourth room has a circular box on top of a table. Rotate the camera to find a letter containing lore behind the box.

Rotating two slider puzzle
Rotate the camera to the right of the front puzzle to view a puzzle with two sliders.

Rotate the lower section until two slots line up with the sliders.

Push both sliders down to unlock the center compartment and get a Wheel.

Wheel puzzle
Place the Wheel on the center of the front puzzle.

Rotate the Wheel to push all four pegs in. This will unlock the next puzzle.

Numeral puzzle
This puzzle involves clicking the metal button to rotate the three rings at the top and rearranging the numerals at the bottom over a few rounds. The goal is to have all of the blue bars in a horizontal line through the center. The numeral beneath the block determines how many times it will move when the button is pressed.

For example, in the image below, the left ring is two moves away, the center ring is three moves away, and the right ring is one move away.

Rearrange the numerals so that the amount of the numeral is the same as the number of movements the ring needs to make. Clicking the metal button now will align the blue segments. This causes the puzzle to rotate, beginning a second round.

Completing the second round unlocks a slider.

Slider it to transform the box into a tall building.

First Ornament Piece
Rotate the camera to view the back of the table. There is a small slider next to an item stuck beneath the glass. Pull the slider to move the glass and get an Ornament Piece.

Tower and roof puzzles
One of the building's towers is not screwed into its base. Rotate the gear to tighten it and get a Crank Handle.

The Crank Handle can be placed onto the top of the building and rotated to reveal a giant gold egg.

The tower to the left of the main entrance has a panel that can be pulled down.

This reveals a red flag, which can be pulled down as well.

The final tower has a small lock on it. Pull the blue pin out to release the lock and get a second Ornament Piece.

There is a small gear on the platform the egg is on.

Rotate it to get a Gong Mallet.

Front door puzzle
Add the two Ornament Pieces to the front door.
