Chapter 1 Overview: Breach at the Precinct & The Cabin in the Woods

The story begins in the police station where Kate Gray's desk is cordoned off with crime scene tape following a cyber assault. Before meeting your informant, Hacksaw, you need to clear the workstation and establish your initial lead.

Station Desk -> Chip Reader (63849) -> Informant's Cabin -> Snowblower Assembly -> Keypad (40827)

Investigate Kate's Desk: Pick up the chip reader resting inside the evidence box on the floor.
Access the Terminal: Place the reader onto the desk next to the monitor. Inspect the chip reader closely to spot the bolded sequence: 63849. Type this five-digit code into the terminal to unlock the computer.
Arrive at Hacksaw's Cabin: Kate and Murphy arrive at the remote hideout amidst heavy snowfall. Murphy discovers Hacksaw is not answering his phone after reports of a shootout.
Repair the Snowblower: You cannot reach the porch through the heavy snowdrift. Collect three components scattered in the front yard:
- Wheel: Near the left fence line.
- Nozzle: Beside the walkway.
- Fuel Canister: Resting near the porch steps.
Clear the Path: Attach the wheel, nozzle, and fuel canister to the snowblower. Run the machine over the yard to clear away the snow drifts completely.
Decipher the Cabin Keypad: Pick up the loose metal number plates revealed beneath the snow. Place them onto the board fixture on the right wall. Aligning the numbers correctly across the top row reveals the sequence 40827. Enter 40827 on the door keypad to gain entry to the cabin.

Location	Key Object Found	Action Required	Resulting Code / Outcome
Police Precinct	Chip Reader	Read bold digits on reader casing	Unlocks Kate's PC (`63849`)
Cabin Front Yard	Wheel, Nozzle, Fuel	Assemble onto snowblower	Clears deep snow drift
Front Porch Board	Metal Number Plates	Arrange numbers on upper row	Door keypad code (`40827`)

Following this on thin ice walkthrough will save you from random guessing and conserve your in-game currency during early investigations.

Cracking the Informant's Safe: The Tattoo Decryption Puzzle

Inside the cabin, the scene turns grim. The informant has been fatally shot, and foul play is evident. You must catalog the room, uncover hidden compartments, and open the heavy floor safe.

Open Window -> Cut Floorboards (Hacksaw) -> Wash Safe -> Count Tattoos -> Unlock Safe (9416)

Start by clearing the clutter. Push aside the disheveled mattress and roll back the floor rug. Open the window shutter to bring natural daylight into the dark room. Collect the cloth curtains from the window frame. Open the wall cabinets to locate the locked mini-game compartment and pick up the metal hacksaw tool.

Examine Hacksaw's body across four distinct points of interest:

Check his phone case to discover the phone has been taken or concealed.
Inspect his prosthetic leg to identify a fastened panel.
Collect the paper symbol strip lying close to his hand.
Inspect his body tattoos closely.

Use the hacksaw on the loose, squeaking floorboards near the bed to expose a locked iron safe caked in dried blood. Step outside to the puddle created by melting snow, dampen the cloth curtains, and return inside to wash the blood away from the safe's dial.

As outlined in this on thin ice walkthrough, the safe requires a four-digit combination calculated by matching the symbols on the paper strip to the matching tattoos on Hacksaw's skin.

Strip Symbol	Visual Description	Body Tattoo Locations	Total Count (Safe Digit)
Arrow	Pointed directional arrow	Arms, neck, and chest	9
Skull	Classic skull icon	Forearms and torso	4
Heart	Anatomical/cardiac heart	Upper chest and shoulder	1
Wave	Water current ripples	Wrist and collarbone area	6

Enter 9416 into the safe's numeric lock. Inside, you will collect:

A confidential handwritten letter.
A bundle of colored triangle tiles.
A professional lockpin gun.

Navigating the Backyard: The Flaming Car & Ice Stairway Puzzle

Equip the lockpin gun to pick the lock on the cabin's reinforced back door. Stepping outside reveals a chaotic crime scene: a car engulfed in flames and fallen gang members in the snow.

Extinguish Fire -> Search Bodies (Crowbar & Wrench) -> Solve Ice Stairway -> Open Car Door

Before you can safely inspect the vehicle, you must gather tools and extinguish the blaze:

Strip the weather tarp off the outdoor grill to find a fire extinguisher and a can of cleaning oil.
Clear the snow patch beside the steps to uncover a rusted lockbox. Apply the cleaning oil directly onto the rusted latch to prep it for later unlocking.
Approach the frozen ledge puzzle labeled the Ice Stairway.

In this stage of our on thin ice walkthrough, players often get tripped up by the Ice Stairway sliding mechanic. The objective is to slide numeric ice slabs across the grid until each numbered block rests directly in its matching numerical indentation.

[Target 1] <--- Slide Block 1 across buffer lanes
[Target 2] <--- Use spare buffer tiles to bypass blockers
[Target 3] <--- Lock final sequence to bridge the ledge

Once across, douse the vehicle fire with the fire extinguisher. Inspect the two bodies near the wreckage to retrieve a heavy crowbar and an adjustable wrench.

Hazard / Obstacle	Item Needed	Source Location	Immediate Result
Blazing Car Fire	Fire Extinguisher	Under grill tarp	Extinguishes vehicle fire
Rusted Box Latch	Cleaning Oil	Under grill tarp	Dissolves heavy rust
Collapsed Ledge	Ice Blocks	Ice Stairway puzzle	Forms stable walkway
Jammed Car Door	Crowbar	Body near vehicle	Grants access to phone cord
Broken Wheelchair	Wrench	Body near vehicle	Yields small brass key

Use the crowbar to pry open the vehicle's warped passenger door and retrieve a spare phone charging cord.

Unlocking Hacksaw's Phone & The Mailbox Mystery

Continuing our on thin ice walkthrough, return inside the cabin to assemble your electronics and bypass Hacksaw's biometric security.

Fix Wheelchair -> Get Key -> Open Box -> Unscrew Leg -> Charge Phone -> Face ID Unlock

Use the wrench on the damaged wheelchair resting near the interior doorway. Tightening the bolts releases a small key. Walk back outside to the burnt car and use the small key on the oiled lockbox. Inside, you will discover a precision screwdriver along with a second set of triangle tiles.

Inside the cabin, use the screwdriver to loosen the screws on Hacksaw's prosthetic leg. Inside the hidden compartment lies his dead smartphone.

Powering the Device: Plug the charging cord into the wall outlet and place the dead phone onto the wireless charging station on the counter.
Conversation Interlude: Kate and Murphy converse regarding the syndicate while the battery charges up to functional levels.
Biometric Bypass: The phone features an active facial recognition lock. Select the phone from your inventory, aim it at Hacksaw's face, and authenticate the lock screen.
Reading the Transcripts: Browse through the message threads. The logs reveal direct death threats from the ransomware organization, along with confirmation that a critical package was left in the outdoor mailbox.

Step back out to the cabin's front driveway. Use the unlocked phone to transmit the digital signal code to the smart mailbox. Open the lid to claim the third set of triangle tiles and an encrypted geographic chart.

The Triangulate Mini-Game & Uncovering the Hidden Safe

With all triangle tiles collected from the safe, the yard lockbox, and the mailbox, return to the wall cabinet inside the cabin. Insert the pieces to activate the Triangulate puzzle.

Insert Triangles -> Rotate Conduits -> Route Electric Dot -> Collect Crime Scene Photo

This mini-game requires you to navigate an electric current from the left power source over to the yellow target triangle situated on the far right. Every time the electrical charge moves across a tile, that tile immediately turns 90 degrees clockwise.

Community reports note that working backward from the yellow termination triangle helps visualize which orientations will connect properly.
Avoid looping your current into dead-end circuits, as this forces you to reset tile angles.

Successfully guiding the current completes the circuit and drops a vital photograph from the secret cabinet partition.

Clue Item	Acquired From	Placement	Final Discovery
Letter	Informant's Floor Safe	Pinned to Evidence Board	Deciphers encryption alignment
Chart	Front Driveway Mailbox	Pinned to Evidence Board	Maps file coordination nodes
Photograph	Triangulate Cabinet Puzzle	Pinned to Evidence Board	Completes trigger mechanism

Affix the letter, the chart, and the crime scene photograph onto the investigation pinboard on the cabin wall. Arranging these three pieces exposes the hidden mechanical safe within the wall recess. Extract the encrypted hard drive containing Hacksaw's ransomware evidence.

This critical milestone in our on thin ice walkthrough leads directly into the cinematic climax of Chapter 1, setting up your team's pursuit of the syndicate mole.

Expert Tips for Playing Adventure Escape Mysteries

Navigating Kate Gray cases can challenge even veteran point-and-click puzzle players. Keeping an eye out for subtle environmental cues while reading an on thin ice walkthrough makes your playthrough smoother and far more rewarding.

Scan Every Quadrant Methodically: Tap or click along the outer borders of scenes. Inventory items like the wrench, cleaning oil, or metal numbers frequently blend directly into snowy terrain or rubble backgrounds.
Keep a Clue Notebook: While games in the series store clues in your inventory, jotting down numbers (such as tattoo tallies or chip reader serials) prevents constant screen switching.
Observe Directional Triggers: When examining bodies, wall panels, or electronic devices, pay attention to arrow orientations or color-coded indicators. They almost always dictate the entry sequence of multi-digit locks.
Conserve Puzzle Skips: Puzzles like the Ice Stairway or Triangulate can feel challenging on your first attempt, but their patterns are deterministic. Save your in-game stars for complex logic puzzles in later chapters.

Frequently Asked Questions (FAQ)

What is the safe code for the cabin in the on thin ice walkthrough?

The cabin floor safe code is 9416. You derive this number by dampening the cloth curtains in the outdoor puddle, wiping the blood off the safe door, and cross-referencing the symbol strip with Hacksaw's tattoos: 9 arrows, 4 skulls, 1 heart, and 6 wave symbols.

How do I open the cabin front door if the keypad is not responding?

The front door requires you to find the loose metal numbers buried under the snowdrifts. First, locate the wheel, nozzle, and fuel can to fix the snowblower. Blow the snow away, grab the numbers, place them on the wall board to form 40827, and punch that code into the keypad.

Where are all the triangle pieces located in Chapter 1?

There are three separate sets of triangle tiles required for the cabinet puzzle:

Inside the blood-covered floor safe beneath the loose floorboards (Code: 9416).
Inside the rusted metal lockbox near the flaming car (opened using cleaning oil and the small key from the wheelchair).
Inside the front driveway mailbox (unlocked using Hacksaw's charged smartphone).

How do you unlock Hacksaw's phone without a passcode?

After connecting the charging cord to the wireless pad and letting the battery power up, select the phone and tap directly on Hacksaw's face. The device uses facial recognition security, automatically granting access to his SMS records and the mailbox transmitter.
