Muhit Rahman lives off two things: gaming marathons and endless cups of tea. He writes guides, reviews, and occasionally forgets that real life doesn’t come with checkpoints. His favorite genres are Soulslike and Metroidvania, with Dark Souls III, Hollow Knight, and Dota 2 forever holding top spots on his all-time list.

Welcome to our walkthrough for The House of Tesla. In this part, we’ll be wrapping up the remainder of Wardenclyffe Laboratory.

After solving the Faraday Cage puzzles in the outer lab, you’ll gain access to the inner tower. We’ll take you through each challenge step by step and show you how to solve them.

The Safe

As you enter the Inner Lab, take a quick look around the room. It almost looks like an office. Near the cupboard in the corner, you’ll spot a silver colored safe with a pipe running out of it through the top.

Take a closer look at it. At the top of the safe, near the big pipe, you’ll notice a slot for a lightbulb. As it happens, we picked one up in the outer lab section. Place it in the slot and it’ll slide inside the safe.

Then zoom in on the front part of the safe. You’ll notice three rings that you can rotate. The outer ring has a triangle, the middle ring has a square, and the inner ring has a circle cutout. Rotating the rings changes the number of dots you can see through the cutout.

To solve this puzzle, you need to count the specific number of triangles, squares, and circles etched on the safe’s front section. Then rotate the ring that matches the shape so that it shows that specific number of dots through the cutout.

Rotate the outer ring so that it shows 3 inside the triangle cutout, set the middle ring to 5, and the inner ring to 4. The safe will pop open immediately. Take a look inside the safe.

Pick up the green object on the right. It’s the Left Panel. We’ll get to it later. Inspect the central mechanism inside the safe.

There are three glass discs with some metal parts inside them. You can rotate them all independently. They seem to form an image if you place them in the correct position.

The image above shows you the correct position for the glass discs.

When you solve this puzzle, the mechanism moves out of the way, and you can spot two cylinders with different objects inside. You can also see a small keyhole on the platform below the cylinders.

Back away from the safe for now and head towards the ornate desk at the far end of the room.

The Desk

As you head toward the desk, you’ll see a large armillary sphere in the middle and two green desk pieces at the top.

The desk piece on the left seems to be complete, while the one on the right is missing two panels. You already found one panel inside the safe. Attach the Left Panel you picked up earlier to the desk piece on the right.

Next, take a closer look at the armillary sphere. Adjust the three discs so that the side of the sphere with the constellation lines up and faces towards you. This will open a hidden panel on the side of the table.

Click on the outer ring of the armillary sphere to pick up the Large Ring.

Now, take a closer look at the panel that you just unlocked.

You’ll notice interconnected rings similar to the one that you found when you opened the door to the Wardenclyffe Laboratory. Like before, you can rotate the rings, each ring independently. You’ll also spot two metal symbols inside the rings. These symbols match the symbols you saw at the top of the two desk pieces on the table.

To solve this puzzle, you need to get the symbols to their proper position inside the panel. The image above shows you the placement.

Solving the puzzle opens a hidden compartment behind it. Pick up the Right Panel.

Return to the table and attach it to the desk piece on the right. Note that the three pieces can be moved along the marked line.

Take a closer look at the desk piece on the left. You’ll have to mirror the position of the panels on the right side.

Here’s the proper position for the desk piece on the right.

Check the bottom part of the table. Drag the two metal pieces toward each other at the center.

Doing so opens the central section of the table, revealing a series of books inside. Take a closer look at it.

You’ll see that the books are numbered 1, 2, 3, 4, 5 & 9. Pressing the red buttons under each book pushes them out of their slot.

Click the red button under the book numbered 9. Rotate the number 9 to turn it into a 6.

This activates the three leaf-shaped discs on the book. If you look closely at the discs, you’ll notice that the pattern imprinted on them resembles the books numbered 1, 2, and 3. Press them in the correct order to solve the puzzle. We’ve marked the order in the image above.

This opens up the side of the book. Pick up the item inside to collect the Triangle-Base Key.

Return to the safe from earlier and use the Triangle-Base Key on the keyhole below the cylinders. Rotate the key, and one of the cylinders will shoot through the vacuum tube upwards.

This will also activate a spiral staircase, allowing you to reach the upper floor of the lab.

The Mechanical Arm #1

Head up the spiral staircase and enter the room on the left.

You’ll spot a mechanical arm on a table on the right. Interact with it.

You can see the arm holding something in its hand, but you can’t pry it open. Take a closer look at the panel on the central part of the arm.

You’ll spot five tracks with one or two cylindrical blocks on each of them. The switch on the side runs a wire from the hook at the bottom part of the arm. If the hook is lined up with one of the cylindrical blocks, it attaches itself to the track, allowing you to move the entire track left or right.

To solve this puzzle, you need to run the wire from the bottom all the way through to the top, attaching to a cylindrical block on each track.

The video above shows you how to solve this puzzle.

Once you’re done, pick up the Metal Clamp that the fist was holding.

Back away from the arm. You’ll spot an aura coming from the incomplete automaton at the corner of the room. Click on it to enter the second Tesla Memory for this chapter.

Tesla Memory

Watch the cutscene and choose Reason as the answer for the quiz segment. This will take you to the puzzle segment of the flashback.

You’ll see four wooden blocks spread out across four tracks. Each wooden block has a wooden pin on the left. There’s a metal piece with notches on it running perpendicular to the tracks. Your goal is to position the blocks so that the wooden pin sits in the notch on the metal piece.

It’s a pretty straightforward puzzle. Simply wiggle the blocks so that you can position the pins along the metal arm. This will complete the Tesla Memory.

The Gas Room #1

After exiting the Tesla Memory, you’ll find yourself standing in front of the incomplete automaton. You can see the mechanical arm holding something that looks like a pigeon, but the arm is missing a lever. Exit the room for now.

Take a closer look at the large device near the spiral staircase. You’ll see the cylinder that shot up through the vacuum tube from the safe sitting on a track. You can move the track to the side. There are three tubes where you can move the cylinder. Move it under the tube on the right and pull the lever on the left.

The object will shoot up through the tube and to its next destination. You’ll see it again soon enough.

Go through the only door you have left to explore on the upper floor.

This takes you to a room with a large cupboard with multiple small shelves inside. It’s on the other side of a glass wall. Take a closer look at it.

A closer look shows you that there are three gas pumps on the outer parts of the shelves. The glass tubes inside the shelf are used to transfer gas through the different parts of the shelf.

There are three Test tubes at the bottom. Your goal is to fill up the test tubes at the bottom with the gas.

Back away from the shelf for now and turn right. Head towards the desk.

Rotating the steering wheel moves the cart behind the shelf. rotate it all the way to the left so that you can reach it through an opening.

Head towards the cart and attach the Metal Clamp to its top. You can use the cart to grab the test tubes. But you have to fill it with gas first.

Activate your Tesla Prototype and look around the room. You’ll find a junction behind the desk with the steering wheel. Interact with it.

Since we already sent the cylinder from the safe up the third vacuum tube, we can now create a connection to the rectangular box above the shelf.

Interact with the big cupboard. You can now move the Rectangular box across the different shelves. If you move it to a shelf with a glass tube, it’ll grab the tube. Then if you move the box to a different empty shelf, it will place the tube in the empty box.

Use the image above as reference to fill up one of the test tubes with gas.

Return to the desk with the steering wheel, and rotate the wheel all the way to the right so that the clamp can grab the Test Tube.

Then bring the cart over towards the opening so that you can collect it.

Head down the spiral staircase and turn left to find a device with five test tubes. Head towards it.

Place the Test Tube in the empty slot.

Flip the switch at the center. The machine will power on and a drawer will pop open.

Pick up the item inside to collect the Cross-Base Key.

Return to the safe on the ground floor and use the Cross-Base Key with the empty keyhole. Turn the key and watch the second cylinder shoot up through the tube.

You’ll also see a hidden chamber open up inside the safe. Pick up the item inside to grab the Switch.

Return to the vacuum pipe machine upstairs. Pull the track to the left so that the cylinder drops into it.

Then move it under the middle pipe and pull the lever to shoot it back up.

Mechanical Arm #2 and the Winged Pigeon

Return to the small room upstairs and interact with the automaton. Take a closer look at the Mechanical Arm.

Attach the Switch to its slot on the left side of the arm. You already know how this puzzle works.

Run the wire through all the cylindrical blocks across the five tracks to solve it.

Pick up the Metal Pigeon from the hand afterward.

Interact with the Mechanical Pigeon in your inventory.

Pull the lever on its chest downward to open its wings. Then, drag the wind along the line. Finally, pull the legs apart to complete a Winged Metal Pigeon.

Head back downstairs and look at the wall on the right. Take a closer look at the stand on the table in front of it.

Place the Winged Metal Pigeon on the stand. This unlocks the circular panel on the wall behind the pigeon.

Pull the panels apart and inspect the maze-like structure behind the electrode.

Use the Large Ring you picked up earlier with the panel. This clicks into place in the inner slot, allowing you to rotate it.

This is essentially a maze where your goal is to move the green rider at the top all the way to the center towards the electrode.

The video shows you a quick route that we took to solve this puzzle.

Once solved, interact with the Electrode in the middle to pick it up.

The Gas Room #2

With the Electrode in your hand, head back to the room with the gas tubes. Place the Electrode in the metal clamp of the cart.

Use the steering wheel on the desk to send the cart all the way to the right. A mechanical arm will grab the Electrode and hold it in place behind the glass.

Use the rectangular box to grab the Electrode and place it on the circular device on one of the shelves.

Turn on your Tesla Prototype and interact with the electrical field at the corner. Then set up a complete circuit as shown in the image above.

Use the switch on the right side of the glass to open a few more panels, revealing some additional glass tubes you can use. Interact with the shelf to start the second part of the gas tube puzzle.

You’ll notice that the gas from the three different canisters is now color-coded. You need to mix the gas from three canisters and fill up the two remaining test tubes with it.

Check the images above to see how to route the tubes to fill up the two test tubes.

Once you solve the puzzle, the mechanical arm at the bottom of the shelves will extend outwards. Rotate the steering wheel at the desk clockwise to grab the arm, then pull the cart back towards the opening so that you can pick it up.

Head back to the vacuum tube machine and pull the lever down to bring one of the cylindrical devices back. Then send it up the chute on the left so that it returns to the safe downstairs.
