On Thin Ice game Chapter 1 Walkthrough
On Thin Ice game begins with Kate Gray investigating a ransomware attack at the police station. The opening chapter quickly shifts from computer evidence to a snowy cabin, a crime scene, and a chain of environmental puzzles. Search every highlighted object before leaving an area because several tools are needed later.
Video Highlights:
- Police station access code and the first investigation sequence
- Cabin entry, body clues, safe combination, and phone recovery
- Ice block bridge, burnt vehicle, mailbox, and triangle puzzle
- Final evidence sequence involving the letter, chart, and photograph
| Objective | Required action | Solution or result |
|---|---|---|
| Police computer | Use the chip reader and inspect the highlighted digits | 63849 |
| Snowy cabin | Repair the snowblower, clear the entrance, and arrange metal numbers | 40827 |
| Cabin safe | Count arrows, skulls, hearts, and waves on the body | 9416 |
| Dead phone | Charge it, then use facial identification on Hacksaw | Unlocks threatening messages |
| Mailbox | Use the phone after reading the delivery message | Obtain triangles and chart |
| Evidence wall | Place the letter, chart, and photograph together | Recover Hacksaw’s hard drive |
Police Station and Cabin Entry
Start by taking the chip reader from the box near Kate’s desk. Place it on the desk, inspect the updated monitor, and enter 63849 into the computer. After the investigation moves outside, collect the wheel, nozzle, and fuel before repairing the snowblower.
Use the machine to clear the snow from the cabin entrance. Pick up the metal numbers and arrange them according to the board’s nail pattern. The resulting cabin code is 40827.
The Cabin Crime Scene
Inside the cabin, move the mattress and rug, open the window, and collect the curtains. Examine the body carefully, including the tattoos and the loose floorboard. Use the hacksaw on the floorboards to reveal the safe.
Wet the curtains outside, then use them to remove the blood from the safe. The symbol strip identifies four categories that must be counted:
| Symbol | Count | Safe digit |
|---|---|---|
| Arrow | 9 | 9 |
| Skull | 4 | 4 |
| Heart | 1 | 1 |
| Wave | 6 | 6 |
Enter 9416 to open the safe. Take the letter, triangles, and lockpick gun. The lockpick gun opens the nearby door and leads to the outdoor vehicle area.
Inspect clues before using tools. In the cabin, the symbol strip only becomes useful after the safe is cleaned and the body markings are visible.
Chapter 1 Evidence and Triangle Puzzles
The second half of Chapter 1 combines exploration with two increasingly abstract puzzles. The ice bridge is solved by sliding numbered blocks into their matching positions, while the triangle puzzle uses rotation to guide an electrical point across the board.
Clear the vehicle area
Use the fire extinguisher on the burning car. Search the bodies to obtain a crowbar and wrench, then use the crowbar to open the vehicle and collect the phone cord.
Repair the wheelchair
Return inside and use the wrench on the wheelchair. Take the small key, then use it on the rusted box outside after applying cleaning oil.
Recover the phone
Use the screwdriver from the box to open the compartment in the body’s leg. Place the phone on the wireless charger and wait for it to power up.
Read the messages
Unlock the phone with Hacksaw’s face. Read the messages to discover the package delivery clue, then use the phone to open the mailbox.
Finish the evidence puzzle
Collect the remaining triangles and guide the electrical point to the yellow triangle. Combine the resulting photograph with the letter and chart to reveal the hard drive.
The ice bridge puzzle requires sliding blocks until each numbered ice cube reaches its corresponding slot. Move blocks only as far as an obstacle allows, and create open lanes before trying to reposition a trapped number.
For the triangle puzzle, each move rotates the triangle that the electrical point lands on. Plan the route toward the yellow endpoint rather than clicking randomly. Once the puzzle is complete, place the letter, chart, and photograph on the wall to finish the chapter.
Search First
Check cabinets, rugs, bodies, vehicles, and hidden compartments before attempting a puzzle.
Track Tools
The crowbar, wrench, screwdriver, phone cord, and cleaning oil each unlock a later interaction.
Revisit Areas
Return to the cabin and mailbox after recovering the phone or opening the vehicle box.
Do not discard an apparently useless item. Several Chapter 1 tools are collected in one location and used only after returning from another area.
Chapters 2 and 3 Investigation Guide
Chapter 2 moves the investigation into a negotiator’s office, where Kate must disable a robot, restore a computer system, and escape through a blocked elevator route. Chapter 3 returns to the police station and focuses on identifying the traitor.
| Chapter | Main setting | Key objectives | Important solution |
|---|---|---|---|
| Chapter 2 | Negotiator’s office | Disable robot, restore systems, escape the office | Elevator button pattern: 4365 |
| Chapter 3 | Police station | Open hard drive, wake Dan, identify the traitor | Computer password: 5937 |
| Chapter 4 | Snowy hideout | Cross drones, rescue Murphy, defeat Sticks | Use the counter chart |
Chapter 2: The Negotiator’s Office
Question the robot and note the three highlighted clues: first, central, and last. Match the shield, hourglass, and no-talk symbols in that order to open the case. Use the wire, capacitor, and power supply to assemble the EMP device and disarm the robot.
Continue by collecting the computer chips, screwdriver, ladder, and other office items. Repair the lamp with duct tape and solve the corner-based image puzzle. The elevator opens after the image is restored.
At the elevator panel, match the button designs to the visible examples. The correct sequence is 4-3-6-5. In the negotiator’s office, arrange the displayed objects on the shelves according to the background clues. Completing the arrangement clears the elevator path and allows Kate and Penny to escape.
Chapter 3: Finding the Traitor
Use the colored tree clues to open the hard drive. The correct values are 21, 10, and 12. In the computer laboratory, wake Dan by using the available items, then assemble the computer with the graphic cards and coolant.
The password clue uses four symbols. Repair the photo frame to reveal their values:
| Symbol | Value |
|---|---|
| Clock | 5 |
| Snowflake | 3 |
| Fish | 9 |
| Gear | 7 |
Enter 5937 to access the computer. Rearrange the colored rows so yellow is at the top, white is in the middle, and green is at the bottom. The contact book reveals the phone connected to Dan, identifying him as the apparent traitor.
Later, clean the evidence-room keypad with sanitizer and use the poster clue to count hands, objects, shirts, shoes, and mouths. The resulting code is 4202. After examining Dan’s belongings and monitoring equipment, connect the numbered hexagons according to their available sides.
Many Chapter 2 and Chapter 3 solutions are visual translations. Read the order of symbols first, then transfer their positions or counts instead of guessing the final sequence.
Chapter 4 Final Chapter Walkthrough
Chapter 4 takes Kate and Murphy to Sticks’s snowy hideout. The route includes a gate code, a drone path, a rescue bridge, a hidden door, a generator, and the final fight. Keep the chapter’s tools organized because several interactions happen in a compact area.
First, collect the vodka and clean the frozen gate panel. Read the three poster clues to determine the gate sequence: 99, 12, and 24. Enter the values in order to pass through the gate.
The drone section is an avoidance sequence. Follow the marker route while waiting for drones to move away from the next target. Collect all markers before entering the hideout.
| Area | Item or clue | Use |
|---|---|---|
| Gate | Vodka and poster numbers | Clean the panel and enter 99-12-24 |
| Trap area | Planks, blocks, hammer | Build a bridge for Murphy |
| Fireplace | Three rings and pattern clue | Open the hidden door |
| Generator room | Chisel, fuel, and code | Repair and start the generator |
| Sticks’s area | Book and taser | Disable Sticks’s equipment |
| Bridge | Combat chart | Choose the correct counter actions |
Inside the hideout, use the planks and wooden blocks to build a bridge. Hammer the pieces into place so Murphy can cross safely. Search the fireplace area for three rings and arrange them to match the V-W-X-K pattern.
Separate the three culprits one at a time. Use the hook to access the bag, collect the chisel, and inspect the generator clue. The broken bottle and whiskey provide the fuel needed to run the generator after it is repaired.
Final Fight
The bridge battle is based on counters rather than a traditional health system. Read the combat chart before selecting an action:
- Punch defeats kick.
- Kick defeats elbow.
- Elbow defeats punch.
- Dodge avoids the appropriate direct attack.
- Block counters the stop action.
- Stop counters dodge.
- Dutch counters block and has its own limited interactions.
The exact sequence can vary if an action is selected incorrectly, so use the opponent’s previous move and the counter chart together. Winning the bridge fight completes Kate’s confrontation with Sticks and closes the investigation.
Take a moment to read the combat relationships before acting. The final encounter rewards careful counter selection more than rapid tapping.
