Tenebris Somnia Floor Puzzle Guide: Symbol Code and Tile Route Solutions

What Counts as a Tenebris Somnia Floor Puzzle

A flickering TV, a dead remote, and a grid of symbols on the floor stop more players than any monster in Ivan's apartment building. The Tenebris Somnia floor puzzle is frustrating for one specific reason: the game shows you the code long before it gives you the tool that makes the code usable. This guide walks through the Tenebris Somnia floor puzzle from the demo's apartment sequence, then covers the tile-pattern floor in Desiderium, so you can stop filming your screen in slow motion and start making progress.

Players use "the floor puzzle" for two different challenges in this survival horror, and mixing them up is the first reason people get stuck. One is the symbol grid tied to the TV feed early in the game. The other is a memorization-based tile route much later in Desiderium.

Both are memory puzzles under pressure, but they fail in completely different ways. Here's how each one works, based on walkthrough documentation and player reports.

Solving the Demo Version of the Tenebris Somnia Floor Puzzle

In an October 2024 Steam community thread about the demo's floor symbol puzzle, a player described recording the TV on a phone in slow motion to catch the fast-flashing symbols — and still getting nowhere. The replies never handed over a combo. They asked one question instead: where's the remote to the TV?

The first gate is powering the TV. Once it is on, the puzzle still requires the symbol order shown in your run; published walkthroughs state that sequence is randomized.

Step 1 – Pick Up the Glove on Floor 2

Head into Ivan's office on the second-floor apartment and check the clothes rack on the right side of the room, near the laptop desk. That's where the Glove is stored, according to Gamer Social Club's full puzzle walkthrough. You'll need it in the kitchen, so don't leave the floor without it.

Step 2 – Collect Both Batteries

The remote needs two batteries, and both are hidden on the second floor:

• Bathtub battery: interact with the tub curtain in the bathroom. Be ready — a monster ambushes you here, per Into Indie Games' walkthrough for Floors 3 and 2.
• Washing machine battery: in the kitchen, interact with the fuse box. The power cuts out, but the washing machine keeps running. Stand at the fuse box with the Glove equipped, and the machine finally stops. Interact with it to pull the second battery.

Community reports from the demo thread confirm the same split: one battery in the bathroom, one in the kitchen, and the Glove is mandatory. Skipping the costume rack is the single most common reason players end up one battery short.

Step 3 – Power the Remote on Floor 3

Ride the elevator back up to Floor 3 and return to the first version of Ivan's apartment. In the study, stand at the TV Remote on the desk, open your inventory, and use both batteries. Then interact with the remote a second time to switch the TV on.

Once the TV is running, read the symbol sequence it displays and step on the matching floor symbols quickly enough. The sequence is randomized, so use the pattern shown in your own run rather than a fixed code.

The Desiderium Floor Tile Pattern Puzzle

The second Tenebris Somnia floor puzzle shows up much later, in the Desiderium section, and it's a pure memory test. After you break the initial fly statue, you have to retrace the exact tile pattern you walked in the previous room.

The pattern is randomized for each playthrough, so no guide can give you a fixed route. What you can rely on:

• The statue turns progressively more gold with every correct tile you step on.
• One wrong tile sends you back to the start of the route.
• Reaching the final tile turns the fly statue fully gold and makes it breakable.
• Breaking it shatters the last fly wing and unlocks the door to the theater room.

From the theater room, grab the Lead Fly from the Julia statue near the middle of the room, then use it on the locked door with the fly insignia in the apartment hallway. If you're mid-run and lost the pattern, the honest fix is to walk the previous room again slowly and memorize each step before you commit.

Quick Reference and Common Mistakes

The symbol-floor section and the tile-floor section punish different habits. Here's what usually goes wrong:

• Filming the TV instead of fixing it. Community reports describe players capturing the flicker in slow motion and brute-forcing combos. The reliable path is restoring the remote first.
• Searching for a new remote. The remote exists from the start — it's the batteries that are missing, and they're two floors down.
• Ignoring the Glove. Without it, the fuse box does nothing useful and the washing machine keeps spinning with a battery inside.
• Rushing the tile route. The Desiderium floor resets you completely on a single misstep, and the statue's gold progress is your only feedback.
• Skipping the Old Book. For the related elevator floor puzzle, the color order is written in the Old Book — 3rd floor is blue, 2nd is green, 1st is red, and the ground floor is white. The sequence is randomized each playthrough and leads to Floor -1.

Frequently Asked Questions

Where is the TV remote for the Tenebris Somnia floor puzzle? It sits on the desk in Ivan's study on Floor 3, in the apartment's red-toned room. It starts with no batteries, which is why it looks useless on a first pass.

Do I need to power the TV before entering the symbols? Yes. Restore the remote with both batteries, then use the randomized symbol sequence shown on the TV and step on the corresponding floor symbols quickly enough.

Is the Tenebris Somnia floor puzzle randomized? The Desiderium tile route, the elevator floor-color order, and the early TV symbol sequence are randomized by playthrough. For the early puzzle, follow the symbols displayed in your own run.

Do I need the Glove for both batteries? No — the Glove is specifically required at the kitchen fuse box to shut off the washing machine. The bathtub battery only needs you to open the curtain, though a monster will jump you there.
