On each side, place a Small Slider in the slot and push it down to the bottom of the box.

Moving both sliders will reveal a set of four drawers. Tap each drawer to send it flying out of the box, revealing a red box with a handle in the back.

Pull the handle of the red box to reveal a picture puzzle.

Picture puzzle

Before starting the puzzle, grab the last image from one of the drawers that was taken out. It's lying on the front of the table now that the puzzle is revealed.

Screenshot by Pro Game Guides

Place the new image and the Film onto the board.

Now move the pictures around between the four holes in the board. When a picture is matched with a hole on the board, it will move itself to fit perfectly with that hole. If you're having trouble matching them up, press the button on the lamp to turn it on. The pink light it emits will show the outline of each image around the hole it belongs to.

Screenshot by Pro Game Guides

Once each picture is placed, the pink letters on all four will reveal the solution for the next puzzle. These letters can only be seen using the lamp, so leave it on so you can check them again.

Rotary puzzle

Go to the top of the box and insert the key into the keyhole.

Twist it to unlock the top. Slide each of the golden locks to the side to interact with the rotary puzzle.

The rotary puzzle has one central red button and four smaller mechanisms. Each of the smaller mechanisms consists of six symbols surrounding a red button. The space closest to the larger red button has a red outline around it.

Screenshot by Pro Game Guides

Pressing the central button rotates the four symbols in the red outlined spaces clockwise.

Screenshot by Pro Game Guides

Pressing the smaller red buttons will rotate all of the symbols around them

Screenshot by Pro Game Guides

To complete the puzzle, the letters from the picture puzzle need to be placed in the right places in rotary puzzle. The "R" needs to be placed in the red outlined spot of the top left circle, the "W" in the top right, the "L" in the bottom right, and the "S" in the bottom left.

Knight lances puzzle

At the top of the box is a group of four knights using their lances to restrain the cage in the center.

  • Front left knight.
  • Back right knight.
  • Front right knight.
  • Back left knight.

Small Crown puzzle

Look at the puzzle with the golden sphere in the center.

Place the Small Crown onto this gold sphere.

This will cause the statue of a king to rise up. It's attached to the box by two rows of gears.

Screenshot by Pro Game Guides

Pushing the king against the box will give you a Small Diamond.

Small Statue puzzle

Before inserting the Small Diamond into the hole, solve the puzzle in front of it.

Screenshot by Pro Game Guides

Place the Small Statue onto the gear on the left side.

Screenshot by Pro Game Guides

Moving the Small Statue past one of the golden pieces will open it up, turning it blue.

Screenshot by Pro Game Guides

To solve the puzzle, you need to move the Small Statue passed each piece so that each one is blue. Passing a blue piece will revert it to gold, so you will need to tread carefully. Ideally, the last piece to turn blue would be the one on the far left.

Screenshot by Pro Game Guides

Turning the last golden slider blue will open up a new path. Push the Small Statue to the end of that path.

Screenshot by Pro Game Guides

This will open up a new mechanism.

Screenshot by Pro Game Guides

On the back of the mechanism, rotate the badge so that the open end of the path connects with the path at the top. Push the piece on the top down along the path.

Screenshot by Pro Game Guides

The compartment will open, and the Power Cell can be placed inside of it.

Screenshot by Pro Game Guides

This will shoot a yellow laser towards the box.

Small Diamond puzzle

Place the Small Diamond into the hole where the light shines.

Screenshot by Pro Game Guides

The goal of this puzzle is to rotate the three rows so that the light can touch all of the mechanisms on the edges.

Screenshot by Pro Game Guides

This will give you a Remote Control and return you to the main room.

The side room here features a cozy sitting area, a fireplace, and a red-curtained stage.

Rotate the right dial second to reveal a button hidden behind the second panel.

Piano puzzle

Look over to the piano to find a missing section.

Screenshot by Pro Game Guides

Place the Piano Keys item here.

Screenshot by Pro Game Guides

To solve this puzzle, you need to play the keys until all three golden symbols are in line with the orange line on the piano. An easy way to do this is by placing the left and center orange symbols next to each other. You can then use the right key to place the right symbol in place and the left key to place the two other symbols in place.

When the keys are aligned, the curtains will open to reveal a screen. A film player will rise from the floor as well.
