The Medium Thomas’s Hidden Room: How To Solve The Picture Developing Puzzle



While trying to find Thomas in The Medium, after you reach his office and solve the Clock Puzzle, you’ll enter Thomas’s hidden room, where a new puzzle awaits; but unlike the previous one, it is a bit easier.

Your objective is to search the hidden room, and if you take a look around you’ll notice that this room is in fact a darkroom quite similar to the one you found in Jack’s House.

Or simply put Thomas’s hidden room in The Medium includes a puzzle that is almost identical to the one from Jack’s darkroom.

If you missed Jack’s puzzle, that’s ok, because the only thing you missed is actually a collectible. But Thomas’s hidden room puzzle is mandatory, meaning that you’ll have to solve it if you want to progress the story in the video game developed by Bloober Team.

And that’s exactly what I am going to show you below. How to search the hidden room in The Medium and how to process a picture that will help you move forward with Marianne’s incredible journey.

How To Search The Hidden Room In Thomas’s Office

The first thing that must be outlined here is that although your objective asks you to search the hidden room, in fact, all you have to do is to find several objects and use them to solve a puzzle.

These objects are a tray, and some substances you need to process a picture or a Photo Paper. As such, in order to keep this Medium guide to the point, everything that is not included in the list below is not required for the actual objective.

So let’s start with the objects required for our puzzle, then I’ll tell you how to complete it.

The first substance you need to get is the Fixer. It’s sitting on a chair next to the workbench, or the table where you’ll develop the picture. You can see it below.

Get the Fixer first

Next, head towards the bookshelf and get the tray in the white plastic crate. It’s on the ground, on the left side; just like in my screenshot.

Third, you’ll need a Multigrade. The bottle containing this substance is on the right side of the same bookshelf.

It’s pretty easy to spot if you move several steps from the previous item.

Get the Multigrade from the library

Finally, you need one last substance called Stop.

Return to the workbench, and you’ll find it in the sink, on the left side.

Last but not least get the Stop from the sink

These are the key items you need to move forward with the story; but obviously, you should fully explore the hidden room if you want to find collectibles and other clues; including some interesting books.

Good, so now that we have all materials, it’s time to process a new photo.

The first thing you’ll want to do is to head back to the working table and turn on the red light. This step is mandatory as the note on the wall tells you.

Once you do that, place the tray you found in the empty slot.

Now, you’ll want to fill all three trays with the substances mentioned above.

To keep things easy to track just use the substances in the exact same order, as mentioned below (from left to right):

  • Add the Multigrade in the first tray on your left
  • Add the Stop in the central tray (the one you have found)
  • Finally, add the Fixer in the third tray (the one on the right)

When you are done, your working table should look like this.

How To Develop/Process The Photo Paper

With all substances in place, let’s see what you have to do to process this new Medium Photo Paper.

First, pick the Photo Paper from the stack, then place it on the wooden board (pictured above).

Press the button on the device and count to 5. Pay close attention to the distinctive sound in the background. When you counted to five, shut down the device and pick up the Illuminated Photo.

Place the Illuminated Photo in the first tray on the left. It contains the Multigrade; however, the moment you place it inside count to three then pick up the Multigraded Photo.

Keep in mind that you have to keep the paper in each tray for exactly 3 seconds. Just count to three and you’ll be fine.

Now, sink the Multigraded Photo in the second tray from left to right. Or the one in the middle. It contains the Stop substance. Again, count to three and pick up the Water-bathed Photo.

Finally, place the Water-bathed Photo in the last tray, which contains the Fixer. Count to three and you’re done.

Obviously, you won’t see the face in the picture, but you’ll start a cutscene at the end of which you may want to get ready for some running.

And that’s it! That’s how you solve The Medium Hidden Room Puzzle.

The Medium Thomas’s Office: How To Solve The Clock Puzzle




The Medium Thomas’s Office is a key location Marianne has to explore once she enters Niwa Hotel, and this office comes with a puzzle, we will call the Clock Puzzle.

By solving it, you’ll be able to find Thomas’s Hidden Room, where another puzzle awaits. It’s quite similar to Jack’s Darkroom Photo Paper Puzzle, but it features more elements.

Before we talk about the Hidden Room though, first you’ll need to find it, and this happens only if you complete The Medium Thomas’s Office Clock Puzzle.

And that’s what we’ll cover in the video game guide below.

How To Investigate Thomas’s Office

The moment you enter Thomas’s Office there are several items you may want to focus on if you wish to learn more about the story in the video game developed by Bloober Team.

As such, here is what you should find first.

  • Check the Hotel Niwa Plan on the wall behind the desk. Focus on the lower-left corner to spot Thomas Rekowicz signature
  • Now turn around and investigate the desk. Start with the phone on the left side
  • Also on the desk but on the right side, there is some salt
  • In the right-side drawer, you’ll find the To-Do List memo (collectible)
  • On the ground in the drawer, you’ll find a Flashlight.
  • When you pick up the Flashlight, you’ll find a Small Key in the same drawer. Make sure you don’t miss it because it’s the most important object
  • Finally, there is a picture on the bookshelf in the corner of the room. Nothing important here for now, but remember its location

Great so these are the items you need to find. Now, let’s focus on the puzzle.

How To Solve The Medium Thomas’s Office Clock Puzzle

As you can probably guess this puzzle is focused on the clock in Thomas’s Office. Basically, by setting the clock at specific hours, you’ll be able to discover specific events in the spirit world. You’ll see them on the right side of the screen.

The first thing you’ll want to do here is to interact with the clock and use the Small Key you found to open it.

At this point, you’ll see the clock that looks like the one in my screenshot.

Check this clock in Thomas’s Office

If you want to figure out how to solve this puzzle on your own, the hints (hours) are mentioned in Thomas’s To-Do List. If not, simply follow these steps:

  • Move the clock hands to 4 o’clock, and notice that in the spirit world a spirit well appears on the desk. Get close to it, and absorb the energy
  • Now, move the clock hands to 5 o’clock and you’ll see a hidden entrance in the corner of the room. Also in the spirit world
  • Step away from the clock, and use the “out of body” ability to control Marianne in the spirit world
  • Head inside the hidden room, and unleash the energy on the switch on the wall. You can see it below

Find this switch and release your energy on it

Once you do this you’ll see some sparks on the wires above you.

Now, The Medium Clock Puzzle ends, but there is one last thing you’ll have to do. And this is the trickiest part as the game offers no hints or tips.

How To Find Thomas’s Hidden Room In The Medium

In order to continue Marianne’s story, or move forward, you’ll need to find Thomas’s Hidden Room, and this room requires you to solve the puzzle above first.

Once you do that you’ll have to find a switch, so the real world Marianne can access the same room as the one in the spirit world.

Assuming you finished the said puzzle, while in the real world, head back to the library in the corner of the office.

Now, use the Insight ability (press Ctrl on PC) and look at the picture you see in my screenshot below. Notice the switch?

Find the hidden room using this switch

Interact with it (aka press the green button) and you’re in.

Now both versions of Marianne can advance, but in the next area, you’ll have to solve Thomas’s Office Hidden Room Puzzle.

The Medium Niwa Hotel: How To Enter The Resort




Making your way deeper into the resort is the second main objective you’ll have to complete in The Medium after Marianne leaves Jack’s Funeral House, and although the video game developed by Bloober Team is quite linear, there is a small puzzle you’ll have to solve in order to enter Niwa Hotel or Niwa Resort if you want.

Once inside, things will get a bit complicated; however below I’ll explain how to enter Niwa Resort because this is the first thing you’ll have to do while chasing down Thomas.

Before we start, it’s worth mentioning that The Medium Niwa Resort features two entrances.

The first one is the one at the gates, which allows you to enter Niwa property, and behind the fence, there is a lot of ground to cover.

So, first, you’ll need to enter the Niwa Resorts property.

To do this, while standing at the gates, look behind the security building for a dumpster. Jump on it, then jump over the fence.

Now, you’ll be inside the Niwa Resort, and the next thing you’ll want to do is to fully explore the area. There are no enemies here so feel free to look around because you can find an impressive number of collectibles.

Without spoiling the video game, as you progress through the woods, you’ll reach a rather large clearing where you can see the Niwa Hotel; thus your next objective is to find a way inside the Niwa building.

How To Enter The Medium Niwa Hotel

Good, so now it’s time to catch up with Thomas but to do that, first, you’ll have to open the Niwa Hotel door which is locked.

Obviously, you don’t have a key, which means that you’ll need to find another way around.

To do this, while facing the large building (aka Niwa Hotel), head left and start exploring the parking lot.

Your goal is to find an old car that looks just like the one in my image below.

Medium Niwa Hotel How To Enter

Find this old car

Approach the car, grab the collectible on the front seat, then pop up the trunk by activating the button next to the steering wheel.

Now, check the car’s trunk and grab the screwdriver.

This is the item you’ll need to get inside Niwa Hotel in The Medium; so head back to the front door.

While standing in front of the door, you’ll notice a chain; which well can’t be cut with a screwdriver. So, here is where the second part of the puzzle starts.

The Medium Niwa Resort Door Puzzle

From your current location, head right to find another door. It looks like the one in my image below.

Medium Niwa Hotel Door Puzzle

Head right to find another door you can open

Investigate it, and you’ll see that the door has no knobs, but your old screwdriver can be used as a doorknob.

Select it from the inventory to get inside a small room and start looking around.

Your objective is to find the green dumpster on the left side of the room as you enter.

The Medium Niwa Resort How To Enter

Use this dumpster to get inside

Get close to it, and push it all the way outside, then climb on it, and finally climb the lower roof to sneak through the broken window.

And that’s it. That’s how you enter The Medium Niwa Hotel & Resort; where the real fun begins. Inside you’ll also find Thomas’s Office and an interesting puzzle.
