Chapter 1 Case Overview and Essential Mechanics

Chapter 1 thrusts players into the aftermath of a catastrophic police department ransomware attack. Before Kate Gray and Detective Murphy can step out for dinner, their station is compromised, forcing an emergency dispatch to secure an informant known as Hacksaw. When investigating crime scenes in On Thin Ice, your success hinges on spotting environmental anomalies, collecting key components, and cross-referencing notes across multiple rooms.

Player experience shows that many investigators overlook basic interactive zones because interactive markers blend into the frozen landscape. Always scan the perimeter before committing items or entering codes.

Key Investigation Checklist

Before diving into specific solutions, keep these core investigative habits in mind:

  • Examine Every Corner: Move furniture, rugs, and curtains to reveal hidden compartments.
  • Inspect Your Inventory: Several items must be combined or cleaned before they become usable.
  • Document Environmental Markings: Numbers on walls, scrap paper, and even body art frequently act as ciphers.
  • Track Puzzle States: Many sliding block and circuit puzzles alter their layout per move; plan two steps ahead.

Police Station Lockdown & Reaching the Secluded Cabin

Your assignment begins in the ransacked office where Kate's workstation is cordoned off behind yellow crime scene tape.

Workstation Terminal Setup:
[Box] -> Collect Chip Reader -> Mount on Computer Desk -> Read Highlighted Digits: 6 3 8 4 9

Unlocking Kate's Computer

  1. Tap the storage box beside the taped desk to retrieve the chip reader.
  2. Place the chip reader on the desk directly next to the computer monitor.
  3. Observe the numbers illuminated in bold on the reader's casing: 63849.
  4. Input 63849 into the PC terminal prompt to bypass the lock and pull up the urgent briefing on Hacksaw.

Clearing the Cabin Snowdrift

Upon arriving at Hacksaw's remote safehouse, gunfire has already occurred, and thick snowbanks block the front access road.

  1. Inspect the yard perimeter to collect three essential maintenance items:
    • Rubber Wheel (near the roadside drifts)
    • Blower Nozzle (resting by the fence line)
    • Fuel Canister (tucked beside the outdoor workbench)
  2. Tap the broken snowblower sitting in the yard. Install the wheel, attach the nozzle, and pour the fuel into the tank.
  3. Operate the repaired snowblower across the drift to clear the entrance path.

Bypassing the Front Door Keypad

Once the snow clears, collect the scattered metal numbers lying on the frozen ground. Tap the wooden display board situated to the right of the porch. Arrange the tiles into the upper slots so that the equation balances accurately, producing the sequence 40827.

Approach the cabin door keypad, punch in 40827, and step inside the crime scene.


Safehouse Interior: The Informant's Secret Safe

Inside the cabin, the team discovers Hacksaw deceased from a gunshot wound. To uncover his files, you must search his personal belongings and decode the safe concealed beneath the flooring. This on thin ice walkthrough segment explains how to connect Hacksaw's tattoos with the locked floor vault.

Searching the Cabin

  1. Drag the mattress aside and pull back the floor rug.
  2. Open the window blinds to flood the room with daylight.
  3. Collect the cloth curtains hanging beside the frame.
  4. Inspect the wall cabinetry to reveal an incomplete mechanical puzzle and pick up the hacksaw.
  5. Inspect Hacksaw's body. Note the empty phone case, the prosthetic compartment built into his lower leg, and the symbol strip lying near his fingers.
Floor Safe Discovery:
[Loose Floorboards] + [Hacksaw] -> Cut Planks -> Uncover Bloodied Floor Safe
[Puddle Outside] + [Cloth Curtains] -> Wet Cloth -> Wipe Dial -> Clean Keypad
  1. Use the hacksaw on the loose floorboards to expose a heavy metal safe.
  2. Step back outside to the front porch, dip the cloth curtains into the puddle of melted snow to create a wet cloth, then return inside.
  3. Use the wet cloth to scrub the dried blood off the safe's combination panel.

Deciphering the Body Art Safe Code

Examine the symbol strip from Hacksaw's hand. It displays four distinct icons in order: Arrow, Skull, Heart, and Wave. To find the combination, count the exact frequency of each corresponding tattoo inked across Hacksaw's arms, chest, and neck.

Icon on StripBody Location / OccurrencesFinal Digit
ArrowForearms, collarbone, and hands (9 total)9
SkullBiceps, shoulders, and chest (4 total)4
HeartLeft wrist / chest accent (1 total)1
WaveTorso side panels and forearm bands (6 total)6

Enter 9416 into the safe's dial. The door swings open, granting you an official letter, a set of geometric triangles, and a lockpin gun.


Exploring the Back Patio & The Burning Vehicle

Use your newly acquired lockpin gun to pick the deadbolt on the cabin's rear exit door. Outside, a vehicle is engulfed in flames, threatening to incinerate critical forensic clues.

Extinguishing the Flames

  1. Inspect the patio grill and pull off the protective tarp.
  2. Pick up the fire extinguisher and a bottle of cleaning oil.
  3. Clear away the snow piled beside the patio steps to uncover a rusted lockbox. Apply the cleaning oil directly to the hinges and latch to dissolve the corrosion.
  4. Interact with the ice formations blocking the lower path to begin the Ice Stairway puzzle.
Ice Stairway Objective:
Slide numbered ice blocks across the grid so each block matches its designated numbered slot.
Utilize outer buffer spaces to hold auxiliary blocks while shifting key digits into sequence.
  1. Once the ice bridge is aligned, descend to the burning sedan and use the fire extinguisher to douse the blaze completely.
  2. Search the two fallen syndicate henchmen nearby to recover a crowbar and an adjustable wrench.
  3. Pry open the warped driver's side car door using the crowbar to claim the phone charging cord.

Recovering Hacksaw's Digital Evidence

With the fire suppressed, you must revive Hacksaw's locked smartphone to retrieve communication logs and delivery notices. Following this on thin ice walkthrough sequence prevents unnecessary backtracking between the patio and cabin interior.

Accessing the Concealed Phone

  1. Return inside the cabin. Connect the phone charging cord to the wall outlet near the work desk.
  2. Use the wrench to tighten the loose bolts on the broken wheelchair in the corner; doing so dislodges a small key.
  3. Step back out to the patio lockbox you previously cleaned with oil. Unlock it using the small key to retrieve a screwdriver and additional triangles.
  4. Return to Hacksaw's body. Use the screwdriver to unscrew the casing on his prosthetic leg compartment. Inside, you will find his dead smartphone.

Unlocking the Smartphone and Mailbox

Place the drained phone on the wireless charging pad attached to your cable. After Kate and Murphy review their notes, grab the powered device.

The operating system requires biometric authentication. Community reports occasionally mention confusion here: simply select the smartphone from your inventory and tap directly on Hacksaw's face to trigger the facial recognition scanner.

Read through the unlocked message history. Hacksaw was receiving extortion demands from an unknown insider, and a scheduled drop was recently placed in the cabin's front mailbox.

Walk back out to the front yard. Tap the locked high-tech mailbox and hold the phone up to its optical scanner. The latch pops open, rewarding you with the final batch of triangles and a topographical chart.


Solving the Cabinet Triangulate Puzzle & Chapter 1 Finale

Now that you have gathered all triangular puzzle pieces, return to the wooden cabinets inside the cabin to tackle the chapter's most demanding brainteaser.

Triangulate Puzzle Mechanics:
* Goal: Guide the moving electrical spark from the left input to the yellow node on the far right.
* Movement Rule: Tapping an adjacent highlighted triangle moves the electrical charge.
* Rotation Rule: Every time the spark lands on a triangle, that specific tile rotates 90 degrees clockwise.

Triangulate Step-by-Step Strategy

  1. Insert all collected triangles into the empty cabinet framework.
  2. Before tapping rapidly, plan your path based on tile orientation. Because each triangle rotates automatically upon arrival, landing on a tile changes the outgoing paths for any future pass.
  3. Choose the upper-middle pathway to prevent looping the spark back into dead ends.
  4. Advance the electrical spark step-by-step into the terminal yellow node on the far right edge.
  5. Once powered, the hidden cabinet mechanism clicks open, revealing a black-and-white photograph.

Opening the Secret Wall Vault

To access Hacksaw's encrypted storage drive, head to the evidence corkboard mounted on the cabin wall.

  1. Pin the official letter, the topographical chart, and the photograph onto their matching outlines on the corkboard.
  2. Align the overlapping pinpoints according to the coordinates mentioned across the documents.
  3. The board slides outward, revealing a wall safe containing Hacksaw's high-capacity external hard drive.

Kate and Murphy secure the hard drive just as sirens echo in the distance, concluding Chapter 1. If you run into hurdles in later levels, relying on an updated on thin ice walkthrough will keep your detective work sharp and efficient.


Advanced Puzzle Strategies for Later Chapters

As the investigation expands across the frozen city, puzzle complexity increases significantly. Keep these proven tactics in mind as you progress:

  • Audit Circuit Puzzles Before Rotating: Later chapters feature high-voltage breaker panels. Trace the wire paths backward from the target terminal to the source before rotating any switches.
  • Keep a Scratchpad for Ciphers: Cipher wheels and runic graffiti become common in Chapters 2 and 3. Writing down symbol substitutions as you discover them saves substantial transit time.
  • Re-check Cleared Rooms: Whenever a major plot event or blackout occurs, previously cleared areas frequently spawn new clues or unlock previously deadbolted storage lockers.

Frequently Asked Questions (FAQ)

What is the safe code in Chapter 1 of On Thin Ice?

The cabin safe code is 9416. You discover this code by inspecting the symbol strip in Hacksaw's hand (Arrow, Skull, Heart, Wave) and counting the total number of matching tattoos across his body.

How do I unlock Hacksaw's dead smartphone?

First, retrieve the charging cord from the burnt car using the crowbar. Plug it into the cabin outlet to charge the phone. Once powered, the phone demands facial recognition; tap the phone on Hacksaw's face to bypass the lock screen.

Where can I find all the triangles for the cabinet puzzle?

The triangles are split into three locations: inside the blood-stained floor safe (9416), inside the rusted patio lockbox (opened with the small key from the repaired wheelchair), and inside the front yard mailbox (scanned open using Hacksaw's phone).

Why won't the snowblower start in front of the cabin?

The snowblower requires three separate components scattered around the yard: the rubber wheel, the blower nozzle, and the fuel can. You must attach all three pieces to the snowblower before it will clear the path to the porch.
