On Thin Ice game puzzles: Chapter 1 Walkthrough

Chapter 1 establishes the main puzzle language of On Thin Ice: inspect every object, record visual clues, and combine tools only after the environment reveals their purpose. The most important early sequence moves from the police station to Hacksaw’s snowy cabin, then into the evidence trail surrounding the burned vehicle.

Video Highlights:

  • The opening computer code and cabin entrance sequence
  • The tattoo-symbol safe and ice-block bridge puzzles
  • The phone, mailbox, triangle board, and evidence-room progression
  • The complete route through Chapter 1’s investigation
Observation Tip

Before entering a code, inspect the surrounding objects twice. Several clues in Chapter 1 use shapes, tattoos, or visual arrangements rather than written instructions.

Puzzle or LockSolutionWhere It Applies
Police computer63849Use the bold digits revealed by the chip reader
Cabin keypad40827Arrange the metal numbers using the arrow layout
Cabin safe9416Count arrow, skull, heart, and wave symbols
Phone accessFacial IDUse Hacksaw’s face to unlock the phone
MailboxPhone interactionRead the delivery message before opening it

Begin at the police station by taking the chip reader from the box. Place it on the desk, inspect the highlighted digits, and enter 63849 into the computer. Once Kate and Murphy leave, collect the wheel, nozzle, and fuel near the snowblower. Attach the parts, activate the machine, and clear the snow from the cabin entrance.

At the cabin, collect the metal numbers and place them on the nearby board. Follow the arrow arrangement to form 40827, then enter that number on the door keypad. Inside, inspect the mattress, rug, window, cabinets, curtains, body, phone case, tattoos, and loose floorboards. The hacksaw opens the floor area and exposes the safe.

The safe requires preparation. Wet the cloth outside, return indoors, and wipe the blood from the safe. Then count the symbols shown on Hacksaw’s body:

  • Arrow: 9
  • Skull: 4
  • Heart: 1
  • Wave: 6

Enter 9416 to obtain the letter, triangles, and lockpick gun. Use the lockpick gun on the right-hand door, then investigate the burning car area. Remove the tarp from the grill to find the fire extinguisher and cleaning oil. The oil is needed for the locked box, but the key comes later.

The ice-block puzzle creates a temporary bridge. Slide the numbered blocks until each number reaches its matching position. After crossing, use the fire extinguisher on the vehicle and inspect the bodies to collect a crowbar and wrench. The crowbar opens the car door, while the wrench repairs the wheelchair and reveals a small key.

Use the small key on the rusted box after applying cleaning oil. Take the screwdriver and additional triangles. Return inside, open the compartment in the leg with the screwdriver, and remove the dead phone. Charge it on the wireless charger, unlock it with Hacksaw’s face, and read the messages. The delivery message points to the mailbox outside.

Use the phone on the mailbox to collect the remaining triangles and chart. Place all triangles into the cabinet puzzle. Guide the electrical dot across the highlighted triangles until it reaches the yellow endpoint; each move rotates the triangle where the dot lands. Finally, place the letter, chart, and photo on the wall to reveal Hacksaw’s evidence.

Chapter 1 Puzzle Route and Item Management

The first chapter is easier when treated as a dependency chain rather than a collection of isolated riddles. Several objects cannot be used immediately, so avoid wasting time tapping the same locked container before acquiring its matching tool.

Route Warning

Do not leave the cabin permanently after finding the car. The investigation requires repeated trips between the cabin, vehicle, wheelchair, mailbox, and hidden compartments.

1

Open the Station Computer

Take the chip reader, place it on the desk, and enter 63849 after inspecting the highlighted digits.

2

Reach the Cabin

Repair the snowblower with the wheel, nozzle, and fuel. Clear the entrance, arrange the metal numbers, and enter 40827.

3

Unlock the Safe

Inspect the body and tattoos, cut through the loose floorboards, wet the cloth outside, wipe the safe, and enter 9416.

4

Recover the Phone

Use the lockpick gun, extinguish the car, collect the crowbar and wrench, repair the wheelchair, and use the key on the locked box.

5

Finish the Evidence Puzzle

Open the hidden phone compartment, charge and unlock the phone, access the mailbox, complete the triangle puzzle, and assemble the wall evidence.

Visual Clues

Count tattoos, inspect symbols, and compare repeated shapes before entering a number.

Tool Chains

Many items unlock a second object rather than solving the current puzzle directly.

Backtracking

Revisit earlier rooms after obtaining keys, oil, cords, and repair tools.

The best inventory habit is to examine every new item immediately, but wait to use it until the game highlights a compatible object. For example, the phone cord belongs with the damaged phone setup, while the screwdriver is reserved for the hidden leg compartment. This prevents unnecessary tapping and keeps the route readable.

Chapters 2 and 3: Robot, Elevator, and Traitor Puzzles

Chapters 2 and 3 shift from cabin survival puzzles to police-station investigation mechanics. The central challenge is interpreting visual sequences correctly: robot dialogue positions, image fragments, elevator symbols, computer icons, and hexagon connections all reward careful pattern matching.

Pattern-Solving Rule

When a puzzle presents several symbols, identify their order from the environment first. Do not assume that the symbols should be arranged alphabetically, numerically, or by color alone.

ChapterMain PuzzleKey Solution or Method
2Robot disarm sequenceShield first, hourglass center, no-talk symbol last
2Computer imageRebuild the picture from the corner pieces
2Elevator keypadEnter 4365 using the matching symbol patterns
2Shelf arrangementMatch objects to their background silhouettes
2Elevator escapeSwap tiles to create connected paths for both characters
3Hard-drive lockUse the color-frame clue to enter 21, 10, 12
3Sleeping technicianAssemble the computer with two graphic cards and coolant
3Computer passwordClock 5, snowflake 3, fish 9, gear 7
3Contact-book puzzleArrange rows as yellow, white, and green
3Radio networkConnect hexagons according to their available sides

In Chapter 2, begin by talking to the robot and studying the highlighted dialogue clues. The correct case sequence places the shield first, the hourglass in the center, and the no-talk symbol last. This opens the case containing the wire needed to build an electromagnetic pulse device.

Collect the capacitor, power supply, and related components. Use the chandelier interaction to reveal the hidden door, then take the screwdriver and foldable ladder. Assemble the EMP and activate it to disarm the robot. The computer-chip puzzle follows: rebuild the image by matching the corner pieces and their edges.

The elevator keypad uses symbol styles rather than ordinary numbers. Match each displayed pattern to its corresponding button and enter 4365. At the negotiator’s office, collect the hard drive and examine the room for the objects needed to open the exit. Duct tape repairs the lamp, the rope reaches the elevated area, and the key opens the safe.

The shelf puzzle is solved by matching each object to the silhouette or background clue. Arrange the cup, lamp, clock, horse, document, butterfly, fan, sculpture, cactus, and coral according to the room’s visual references. The final elevator puzzle requires swapping tiles until both Kate’s and Penny’s routes connect to the exit.

Chapter 3 begins with the hard drive. Inspect the colored frames and use the matching environmental clue to enter 21, 10, 12. In the computer laboratory, wake the sleeping technician by using the mug and dripping water. Assemble the computer with two graphic cards and coolant, then repair the photo frame to reveal the password icons.

The icon values are:

  • Clock: 5
  • Snowflake: 3
  • Fish: 9
  • Gear: 7

Enter the sequence in the order shown by the computer: 5397. Rearrange the contact-book rows so the top row is yellow, the middle row is white, and the bottom row is green. Calling the recovered contacts identifies the traitor.

The chapter’s final radio puzzle is a network-connection challenge. Start with the hexagon that has six available sides, then place restricted pieces where their connection options fit. The goal is to create a continuous configuration without leaving an unconnected edge.

Chapter 4: Gate, Rescue, and Final Fight

Chapter 4 combines timed movement, environmental item use, a hidden-door combination, and a final combat-style logic puzzle. The safest approach is to solve each section in order instead of collecting random items.

Final Chapter Tip

The last fight is determined by matchup logic, not rapid tapping. Read which action defeats the opponent’s action, then choose the counter for each round.

At the gate, collect the bottle of vodka and wipe the frozen control panel. The posters provide the bullet-hole sequence. Enter 99, 12, 24 to open the gate. Next, guide Kate through the drone area while collecting all marked points. Pause when a drone changes direction, then move through the open route rather than rushing directly toward the next marker.

Inside the manor, Murphy falls through the floor. Collect the hammer, planks, and wooden blocks, then build the bridge in the required order. Nail the planks into place to rescue him. The hidden door in the chimney requires three rings. Find the missing rings using the hook and firewood area, then reproduce the pattern indicated by the external clue.

Chapter 4 ObjectiveRequired ActionResult

Open the hidden doorCollect three rings and copy the patternReveal the captors
Start the generatorUse the passcode from the bagPower the escape route
Disable the guardUse the book and taserRelease the girl
Win the bridge fightSelect counters by matchupComplete the final confrontation

After opening the hidden door, separate the captors one at a time. Use the hook to open the bag and take the chisel, then inspect the bag for the generator passcode. The chisel opens the globe, revealing whiskey that can serve as fuel. Enter 7427 into the generator and use the syrup to operate it.

The final fight uses a counter system with five actions:

Opponent ActionBest Response
PunchKick or elbow, depending on the displayed matchup
KickDodge or use the listed counter
ElbowDodge or kick
BlockUse an action that bypasses the block
StopDodge rather than block

The exact winning sequence depends on the matchup instructions presented during the encounter. The reliable method is to compare each action with the counter chart before confirming. A common successful route includes dodging early, using a block at the correct opening, following with an elbow, and selecting a kick during the final exchange.

Puzzle Checklist and FAQ

Use this checklist to confirm that the major investigation gates are complete. It is especially useful if a chapter appears stuck after an apparently successful puzzle.

Progress Check

If the next scene does not trigger, inspect the last unlocked item again. Several transitions require examining an object after solving its associated lock.

Essential Puzzle Milestones:

  • Enter 63849 at the police computer
  • Unlock the cabin with 40827 and the safe with 9416
  • Repair the phone, read the messages, and open the mailbox
  • Complete the Chapter 2 robot, elevator, and shelf puzzles
  • Identify the Chapter 3 traitor and finish the Chapter 4 bridge fight

Q: What are the most important On Thin Ice game puzzles in Chapter 1?

The key Chapter 1 puzzles are the police computer code 63849, cabin keypad 40827, tattoo-symbol safe 9416, ice-block bridge, phone investigation, mailbox, and final triangle board.

Q: How do I solve the tattoo safe in On Thin Ice?

Wet the cloth outside, wipe the blood from the safe, then count the symbols shown on Hacksaw’s body. The counts are arrow 9, skull 4, heart 1, and wave 6, producing 9416.

Q: What is the Chapter 3 computer password?

Use the icon values revealed by the repaired photo frame: clock 5, snowflake 3, fish 9, and gear 7. Enter them in the displayed order as 5397.

Q: How do I approach the final fight?

Treat the fight as a matchup puzzle. Read the action relationships, choose a counter for each round, and avoid selecting block against an action that bypasses it.

The strongest general strategy for On Thin Ice is to treat every room as a source of relationships. A number may come from a symbol count, an item may repair another item before opening a lock, and a visual arrangement may define the correct order. Keep a short note of codes, symbol counts, and unresolved objects as you progress through the investigation.
