From booting up a locked workstation to breaking into a confidential informant's fortified safe, every puzzle demands careful attention to environmental clues. Below, you will find comprehensive breakdowns of every code, minigame mechanic, and item combination required to complete the opening act of this acclaimed title from Haiku Games.


Phase 1: Breaching the Precinct and Clearing the Cabin Grounds

The chapter opens immediately following a devastating ransomware attack at the police station. Detective Kate Gray's workstation is taped off, and restoring system access is the immediate priority before she and Detective Murphy can pursue their lead.

1. Cracking the Workstation Code

Look inside the evidence box sitting beside Kate's desk to retrieve the chip reader. Place the chip reader on the desk directly next to the locked computer terminal. The display monitor will flicker and request a five-digit override passcode.

Inspect the physical surface of the chip reader. You will notice five highlighted, bold numbers embedded in its serial imprint: 63849. Enter 63849 into the workstation keypad to bypass the ransomware barrier and retrieve Murphy’s informant briefing.

Workstation Passcode: 63849

2. The Blizzard and Snowblower Assembly

Kate and Murphy travel through a blinding snowstorm to meet their informant, nicknamed Hacksaw. Upon arriving at the remote mountain cabin, gunshots are heard, and a wall of dense snow blocks the main cabin entrance.

To clear the path, you must rebuild the abandoned snowblower in the yard:

  • Locate the wheel resting against the side shed.
  • Retrieve the blower nozzle buried near the fence line.
  • Pick up the red fuel can situated near the walkway.

Combine the wheel, nozzle, and fuel can with the broken snowblower. Once fueled and assembled, drag the machine across the deep snowbanks to expose the front porch, the pathway, and a set of discarded metal digits.

3. Unlocking the Cabin Front Door

After removing the snow, collect the loose metal numbers scattered across the frozen porch. Direct your attention to the wooden board hanging to the right of the cabin entrance.

Place the metal numbers onto the board. Arrange the pieces so that the mathematical equations balance across the top line, yielding the five-digit sequence: 40827. Tap the electronic keypad mounted beside the cabin door, punch in 40827, and step inside to investigate the crime scene.

Phase 2: Processing the Crime Scene and the Tattoo Cypher

Inside the cabin, Kate and Murphy discover the tragic aftermath of the ambush: Hacksaw is dead on the floor. Solving on thin ice chapter 1 requires players to treat this room as a meticulous forensic scene, uncovering physical evidence while respecting every hidden detail on the informant's body.

1. Securing the Cabin Interior

The room is dark and cluttered. Take the following actions to prepare the area for forensic analysis:

  • Pull down the cloth curtains from the window frame to let daylight illuminate the room.
  • Shove the bloodied mattress aside to clear floor space.
  • Pull back the area rug near the center of the room to reveal loose wooden floorboards.
  • Open the overhead wall cabinets to locate a locked mechanical puzzle and pick up the hacksaw.

Examine Hacksaw's body closely. Check his pockets to reveal an empty smartphone case, notice the prosthetic seam concealing a hidden compartment on his leg, and collect the symbol strip resting beside his outstretched hand.

Forensic Checklist:
[✓] Curtains collected
[✓] Hacksaw retrieved from cabinets
[✓] Symbol strip collected from floor
[✓] Compartment identified on prosthetic leg

2. Revealing and Cleaning the Subfloor Safe

Select the hacksaw from your inventory and cut through the loose subfloor boards where the rug was positioned. Lift the boards to unearth a heavy, bloodstained lockbox safe.

The dial mechanism is obscured by dried blood. Step back outside to the front porch, submerge the dry cloth curtains into the puddle of melted snow to obtain a wet cloth, and return inside. Use the wet cloth to scrub the face of the safe clean, revealing four symbol slots corresponding to the paper strip in your inventory.

3. The Tattoo Cypher Solution

To crack the safe's four-digit combination, you must inspect the four primary tattoo clusters on Hacksaw’s body: his chest, left arm, right arm, and neck. Count every occurrence of the symbols shown on the reference strip:

Symbol PatternAnatomical Location NotesTotal Symbol Count
ArrowClustered on forearms and chest9
SkullInked across shoulders and bicep4
HeartInked near collarbone1
Wave / WaterBanded around forearm and wrist6

Enter the four-digit combination 9416 into the cleaned floor safe. The lock will snap open, rewarding you with three critical assets: an informant letter, a set of mosaic triangles, and a specialized lockpin gun.


Phase 3: The Flaming Vehicle and the Ice Stairway Puzzle

Equip the newly acquired lockpin gun and interact with the locked back door on the right side of the cabin. Trigger the pin tumbler mechanism to open the exit, revealing a burning getaway car in the rear yard.

1. Gathering Outdoor Tools

Before tackling the vehicle fire, scan the outdoor patio:

  1. Strip the canvas tarp off the barbecue grill to collect a charged fire extinguisher and a can of cleaning oil.
  2. Sweep away the snow drift beside the wooden bench to expose a rusted metal lockbox.
  3. Apply the cleaning oil directly onto the lockbox hinges to strip the rust away; this box will require a specific physical key before you can access its contents.

2. Solving the Ice Stairway Sliding Puzzle

To reach the burning car safely, you must traverse a frozen drop-off by solving the Ice Stairway puzzle. This puzzle presents players with a numbered grid of sliding ice blocks that must be positioned into sequential numerical slots.

Community reports and player experiences suggest that working from the highest numerical slots down to the lowest prevents you from trapping movable pieces in dead ends. Slide the excess blank buffer blocks into the exterior holding bays, slide the target numbers into their corresponding numerical slots, and lock the stairway in place.

Once the staircase forms, cross the chasm and use the fire extinguisher to douse the blazing car.

Rear Yard Action Path:
Barbecue Grill -> Fire Extinguisher & Oil -> Lubricate Rusted Box -> Solve Ice Stairway -> Extinguish Car

3. Searching the Crash Scene

With the flames extinguished, examine the two fallen gang members flanking the vehicle:

  • Search the body on the left to acquire a sturdy crowbar.
  • Search the body on the right to retrieve an adjustable wrench.

Use the crowbar on the crumpled driver-side door of the burnt car. Pry it open to salvage an intact phone charger cord from the center console.

Phase 4: Recovering Hacksaw's Smartphone and Decrypting Evidence

Now that you have gathered repair tools from the yard, return inside the cabin to bypass the informant's multi-layered biometric security.

1. Repairing the Wheelchair and Opening the Patio Box

Step back inside the main cabin room. Inspect the broken wheelchair leaning against the rear wall. Use your wrench to tighten the loose axle bolts. Once fixed, roll the chair aside to reveal a hidden small key taped beneath the frame.

Head back outside to the patio where you previously oiled the rusted box. Use the small key to unlock the latch. Inside, you will find:

  • A heavy-duty screwdriver.
  • A second collection of mosaic triangles.

2. Extracting and Charging the Smartphone

Return indoors to Hacksaw's body. Select the screwdriver and unscrew the mechanical plate on his prosthetic leg. Inside the hidden cavity sits Hacksaw’s drained, high-security smartphone.

Take the phone to the bedside table:

  1. Plug the phone cord into the wall outlet and connect it to the wireless charging cradle.
  2. Place the dead phone onto the charging pad.
  3. Kate and Murphy will exchange dialogue while the battery recharges to operating capacity.
  4. Once the phone boots, pick it up. The operating system prompts for biometric authentication.
  5. Hold the smartphone up to Hacksaw’s face to bypass the Facial ID security lock.
Phone Recovery Chain:
Wrench Wheelchair -> Small Key -> Unlock Box -> Screwdriver -> Open Leg Prosthetic -> Retrieve Phone -> Charge Pad -> Facial ID Unlock

3. Intercepting the Drop and Accessing the Mailbox

With the smartphone unlocked, scroll through Hacksaw's encrypted messaging threads. The chat logs reveal two crucial narrative details:

  • The syndicate threatened Hacksaw's life shortly before the ambush.
  • A confidential physical package was dropped into the front mailbox earlier that morning.

Exit the cabin through the front door and inspect the metal mailbox standing beside the road. Use the decrypted smartphone to transmit an authorized unlock signal to the digital mailbox lock. Open the box to collect the final set of mosaic triangles and a cryptic investigative chart.


Phase 5: The Triangulate Puzzle and Final Safe Extraction

Having gathered all triangle sets across the cabin, yard, and mailbox, return to the wall cabinets inside the cabin to solve the central puzzle of on thin ice chapter 1.

1. Mastering the Triangulate Puzzle

Open the overhead cabinet and insert all collected mosaic triangles into the empty sockets. This initiates the Triangulate Minigame.

The objective is to guide a pulsing electrical pulse from the starting terminal on the far left across the circuit board to the golden goal triangle on the far right:

  • Every time the electrical charge lands on a triangle, that triangle rotates 90 degrees clockwise.
  • You must anticipate each rotation so the outgoing path aligns with the incoming port of the next adjacent triangle.
  • Avoid routing into dead-end circuits, which forces a sequence reset.

Follow the step-by-step route outlined below to clear the board smoothly:

[Start Node] 
     │
     ▼
[Upper Left Blue] ──(Rotates 90°)──> [Center Top Cyan]
                                            │
                                            ▼
[Middle Green] <──(Rotates 90°)──── [Center Core Node]
     │
     ▼
[Lower Center Teal] ──(Rotates 90°)─> [Far Right Yellow Goal]

When the circuit locks into alignment, the cabinet wall drops open, revealing a hidden crime scene photograph.

2. Unlocking the Wall Safe and Securing the Drive

Now holding three key pieces of documentary evidence—the letter, the chart, and the photograph—turn toward the blank wall corkboard beside the desk.

Pin all three items onto the board. Their combined visual lines, dates, and geographic coordinates trigger a hidden magnetic catch, causing the wall panel to slide back. Behind it lies Hacksaw's primary secret wall safe.

Interact with the safe to pull out the encrypted hard drive containing the complete files on the syndicate's ransomware syndicate. As Kate and Murphy secure the drive, sirens echo through the blizzard, bringing on thin ice chapter 1 to an explosive close.
