On Thin Ice walkthrough: Step-by-Step Chapter Guide

On Thin Ice walkthrough progress begins at the police station, where Kate investigates a ransomware attack before traveling to a snowy cabin. Chapter 1 introduces the main pattern of the mystery: inspect every object, collect seemingly unrelated tools, and revisit earlier locations when a new item changes what you can do.

Video Highlights:

• Police station computer activation and the first five-digit code
• Snowblower repair, cabin entry, and tattoo-symbol safe puzzle
• Ice bridge sequence, phone recovery, and the triangle puzzle
• Evidence collection through the phone, mailbox, and wall display

Police station and cabin entrance

Start by taking the chip reader from the box near Kate’s desk. Place it on the desk hardware, inspect the highlighted digits, and enter 63849 on the computer. After the investigation moves to the snowy cabin, collect the wheel, nozzle, and fuel before repairing the snowblower.

Use the working snowblower to clear the cabin door. Pick up the metal numbers and arrange them on the nearby board according to the nail pattern. The resulting code is 40827. Enter it at the cabin door to continue inside.

Cabin evidence and safe

Inside the cabin, move the mattress and rug, open the window, and collect the curtains, hacksaw, symbol strip, and other visible clues. Use the hacksaw on the loose floorboards to pull out the safe.

Take the curtains outside, wet them in the puddle, and return to clean the blood from the safe. Count the symbols shown on the body using the strip as your reference:

Enter 9416 to open the safe. Take the letter, triangles, and lockpick gun. Use the lockpick gun on the nearby door to reach the burned car and the ice-block puzzle.

Burned car, phone, and evidence

Use the fire extinguisher on the flames, then inspect the bodies for a crowbar and wrench. The crowbar opens the car door, revealing the phone cord. Return inside to connect the cord, repair the wheelchair with the wrench, and take the small key.

Use the key on the locked box near the burned car. The screwdriver from that box opens the compartment on the body’s leg, allowing you to retrieve the dead phone. Charge the phone and use facial identification on the body to unlock it.

Read the messages carefully. The delivery notice points to the mailbox outside. Use the phone to open it, collect the remaining triangles and chart, then complete the triangle puzzle. The electrical dot moves across highlighted triangles, and each landing rotates that triangle clockwise. Guide the dot to the yellow endpoint.

Finish by placing the letter, chart, and photo on the wall display. This reveals the hard drive and closes the chapter.

Chapter 2 shifts the investigation to a negotiator’s office. The main challenge is combining dialogue clues with environmental patterns. Record the order of symbols before interacting with the related devices.

Disarm the robot

Talk to the robot and examine the highlighted words and symbols in the conversation. Set the lock using the shield in the first position, hourglass in the center, and no-talk symbol last. Once the case opens, take the wire.

Search the room for the capacitor and power supply. Use the ladder to reach the needed area, collect the switch, and assemble the EMP device. Activate it to disarm the robot and obtain the computer chips.

Restore the computer and open the elevator

Place the chips into the nearby computer device. The next puzzle uses corner pieces to rebuild the image. Complete the image to activate the elevator.

Before entering, inspect the panel below the elevator controls. Match each visual pattern with the same pattern on the buttons. The sequence is:

Enter 4365 to reach the negotiator’s office.

Office shelves and escape route

In the office, collect the hard drive, fan, duct tape, rope, clamp, and other visible objects. Use the duct tape to repair the lamp, then use the rope to reach the elevated item. The clamp helps you take the final frame.

Arrange the collected objects on the shelves by matching each object to the silhouettes in the background. When the arrangement is correct, the elevator becomes accessible. Complete the final tile-swapping puzzle by building connected paths for both Kate and Penny, then install the robot to finish Chapter 2.

Chapter 3 returns to the police station and focuses on identifying the traitor. The computer puzzles rely on color, shape, and icon matching, while the later investigation requires careful item timing.

Use the contact book to identify the phone that rings in the station. The evidence points to Dan as the traitor, but the investigation continues through his belongings and the prisoner area.

Collect sanitizer and the bent wire. Use the wire to open the evidence room, then use police tape to clear the obstruction. Clean the frozen panel with sanitizer and solve the counting code from the poster:

Enter 40242 to open the panel. Search the belongings, take the papers, and give them to Jacob. Fill the mug with dripping water and use it to wake Dan. Return his glasses when requested so he can explain that his daughter has been kidnapped.

The final Chapter 3 puzzle uses numbered hexagons. Connect each hexagon to the number of sides indicated by its value, beginning with the six-sided piece and then placing pieces with fewer available connections. Use the completed radio-monitoring device to track the gang’s location.

Chapter 4 follows Kate and Murphy to the gang’s location. The route combines stealth movement, environmental tools, and a final action-counter battle. Take time to inspect the warning patterns before moving through the drone area.

Open the gate and cross the drone area

Take the vodka and use it to clear the frozen gate panel. Read the three relevant posters and compare bullet holes with their printed values. The gate code is 99-12-24.

After the gate opens, move through the drone route and collect all three markers. Watch the drone’s position, wait for it to rise or shift away, and then move to the next marker. Once all markers are collected, continue to the manor.

Rescue Murphy and open the hidden door

Murphy falls through a trap, so collect the hammer, planks, and wooden blocks. Arrange the planks to create a bridge, then use the hammer to secure them. After Murphy is safe, search the chimney area for three rings.

Place the rings in the hidden-door mechanism and copy the pattern indicated by the letters V, W, X, and K. The completed mechanism opens the next section.

Separate the captors

The compound sequence requires separating the three captors one at a time. Open the door to send the first woman away, then search the back area with the hook. Take the money, bag, chisel, and generator code.

Use the chisel on the globe to retrieve whiskey, which acts as fuel. Enter 7427 at the generator, load it with the fuel, and activate it. Use the book and taser from the backpack to disarm the remaining guard, then release the girl.

Final bridge fight

The last confrontation uses a counter system. Read the action relationships before committing to a move:

The battle is presented in short rounds, so select the response that counters the displayed action. A practical sequence begins with dodge, followed by block and elbow when the opponent’s actions match those counters. Save the kick for the round where it can interrupt the opponent’s attack. After winning, watch the conclusion with Kate and Murphy.

Use this reference table when revisiting a chapter or checking whether a required item has already been collected.
