On Thin Ice AE Mysteries walkthrough: Chapter 1

Chapter 1 begins with a ransomware investigation at the police station before Kate and Murphy travel to a snowy cabin. The safest approach is to inspect every sparkling object, collect tools before returning to earlier locations, and record each code as soon as you solve it.

Video Highlights:

  • The police computer investigation and the first ransomware code.
  • The snowy cabin, safe, body tattoos, and evidence search.
  • The ice bridge, burned vehicle, dead phone, and final evidence puzzle.
Chapter 1 Route

Solve the computer first, then clear the cabin entrance with the snowblower. Several later tools are obtained outside and must be carried back inside.

Snowy cabin keypad40827Opens the cabin
Tattoo safe9416Reveals the letter, triangles, and lockpick gun
Phone accessHacksaw’s faceUnlocks the dead phone with facial ID
MailboxUse the phoneProvides more triangles and the chart

Start at Kate’s desk and take the chip reader from the box. Place it on the desk, inspect the highlighted digits, and enter 63849 into the computer. After the investigation begins, collect the wheel, nozzle, and fuel for the snowblower. Assemble the machine and use it to clear the snow blocking the cabin.

At the cabin, place the metal numbers on the nearby board. Arrange them to form 40827, then enter that number on the door keypad. Inside, move the mattress and rug, open the window, collect the curtain cloth, and inspect the cabinets. The hacksaw is needed to cut the loose floorboards and expose the safe.

Go outside and wet the cloth in the puddle. Return inside and wipe the blood from the safe. The symbol strip provides the counting order: arrow, skull, heart, and wave. Count the matching tattoos on the body:

Tattoo symbolCountSafe digit
Arrow99
Skull44
Heart11
Wave66

Enter 9416 to open the safe. Take the letter, triangles, and lockpick gun. Use the lockpick gun on the nearby door to reach the outdoor area and the burning vehicle.

Clear the vehicle with the fire extinguisher. Search the bodies for a crowbar and wrench. The crowbar opens the vehicle door and provides the phone cord. Inside the cabin, connect the cord, repair the wheelchair with the wrench, and take the small key. Use the key on the rusted box outside to obtain the screwdriver and additional triangles.

Use the screwdriver on the hidden compartment in the body’s leg. Place the dead phone on the wireless charger, then use Hacksaw’s face to unlock it. Read the messages, which reveal that a package is waiting in the mailbox. Use the phone on the mailbox, take the final triangles and chart, and complete the triangle path puzzle. Finally, place the letter, chart, and photo on the wall to reveal Hacksaw’s evidence and finish the chapter.

Chapter 2: The Negotiator’s Office

Chapter 2 follows the evidence trail to a negotiator’s office. The puzzles focus on recognizing patterns, disabling a robot, restoring power, and arranging objects in their correct positions. Keep the wire, capacitor, power supply, screwdriver, rope, and duct tape because each supports a later task.

Robot Puzzle Warning

The robot’s dialogue supplies the order for the symbols. Record the positions as first, middle, and last before interacting with the control panel.

Disable the Robot

Use the dialogue clues to place the shield first, hourglass in the center, and no-talk symbol last.

Build the EMP

Combine the wire, capacitor, and power supply to disable the office robot.

Restore the Elevator

Complete the corner-based computer image and enter the elevator code 4365.

Escape the Office

Arrange the displayed objects on the shelves, then solve the path puzzle for Kate and Penny.

Begin by speaking with the robot. The important clues identify a shield as the first symbol, an hourglass as the central symbol, and the no-talk sign as the final symbol. Enter that sequence into the case to obtain the wire.

Search the office for the capacitor and power supply. Wrap the wire correctly, assemble the EMP device, and activate it near the robot. Once the robot is disabled, collect the computer chips and inspect the nearby panel. The computer image puzzle is built around the corners; complete the image to open the elevator route.

The elevator panel uses four visual patterns. Match each panel pattern with the corresponding number:

Panel patternNumber
Black and white4
Yellow with black3
Black frame6
Fully black5

Enter 4365 to reach the negotiator’s office. Place the hard drive on the table and continue the conversation. When the negotiator leaves, search the room for the fan, lamp, clock, rope, key, duct tape, and other display objects.

Use the duct tape to repair the lamp. Use the rope to reach the key, then open the safe and take the photographs. The background provides the arrangement clue for the shelf puzzle. Place every object according to its matching silhouette, including the crystal star, lamp, clock, horse, document, butterfly, fan, cactus, coral, and strange sculpture.

Once the shelf arrangement is correct, the elevator becomes accessible. Solve the final tile-swapping puzzle by creating connected paths for both Kate and Penny. Completing both routes ends Chapter 2.

Chapter 3: Finding the Police Traitor

Chapter 3 returns to the police station and shifts the focus from physical evidence to digital clues. The main objectives are opening the hard drive, rebuilding a computer, identifying the traitor, and monitoring the suspect’s phone.

Pattern Clue

The hard-drive puzzle uses the colored frames and matching objects in the scene. Compare the blue, red, and green references before entering the three-number sequence.

1

Open the hard drive

Inspect the colored frame clues and match them with the blackjack, red, and green references. Enter 21-10-12 to unlock the hard drive.

2

Wake the sleeping technician

Find the column and use it to pull the technician away from the computer. Collect the graphic cards, drawer handle, plastic tubes, and coolant.

3

Assemble and unlock the computer

Build the computer with the graphic cards and coolant. Use the photo-frame clues to identify the password sequence: time, snowflake, fish, and gear.

4

Identify the traitor

Rearrange the colored rows, obtain the contact book, and dial the listed contacts. The ringing phone identifies Dan as the traitor.

The computer password puzzle uses four symbols. The matching digits are shown through the repaired photo frame:

SymbolDigit
Time5
Snowflake3
Fish9
Gear7

Enter 5397 to unlock the computer. Rearrange the rows so yellow is at the top, white is in the middle, and green is at the bottom. This reveals the contact book. Dial the contacts in sequence and follow the ringing phone to identify Dan.

After Dan is detained, collect the sanitizer and bent wire. Use the bent wire to open the evidence room. Clean the frozen panel with sanitizer, then solve the five-digit belongings code by counting the objects represented on the poster:

Item countedQuantity shownCode digit
Hands44
Items00
Shirts22
Shoes44
Mouths22

The resulting code is 40242. Open the compartment, collect the evidence, and give the papers to Jacob. Use the water from the cell to fill the mug, then wake Dan. Return his glasses so he can speak clearly and reveal that his daughter has been kidnapped.

The monitoring device requires a battery pack, antenna, and hexagon connections. Attach the antenna to the radio, install the battery pack, and connect the hexagons according to their available sides. Start with the hexagon showing six connections, then place the pieces with fewer possible positions. Completing this network finishes the chapter.

Chapter 4: The Hideout and Final Fight

The final chapter takes Kate and Murphy to a guarded hideout during the blizzard. It combines a gate code, a timed drone route, a bridge repair, a hidden-door combination, generator repairs, and a move-based confrontation with Sticks.

Final Chapter Plan

Collect every nearby tool before crossing into the hideout. The hammer, hook, chisel, broken bottle, fuel, book, and taser each have a specific role.

ObjectiveRequired actionSolution
Open the gateRead the bullet-hole posters991224
Cross the drone areaFollow the marker routeMove when drones change height or side
Rescue MurphyBuild and nail the plank bridgeUse planks, wooden blocks, and hammer
Open the hidden doorMatch the ring patternFollow the V, W, X, K clue
Repair the generatorAdd the correct fuel and enter the panel code7427
Final fightCounter each move correctlyUse the combat rules below

At the gate, take the vodka and wipe the frozen control panel. Inspect the posters and count the bullet-hole patterns. The visible values provide the sequence 99, 12, 24, producing the gate code 991224.

Inside the drone section, move carefully between the markers. Watch the drone’s height and direction before crossing. Collect all markers before entering the hideout. If a drone is moving across the route, wait until it rises or shifts to the other side.

When Murphy falls through the trap, take the hammer and collect the planks and wooden blocks. Arrange the materials as a bridge, then use the hammer to secure the boards. After Murphy is safe, search the chimney for three rings. Place the rings in the hidden-door mechanism and reproduce the pattern shown by the V, W, X, and K clue.

The hidden area contains three enemies. Separate them by solving the nearby room tasks. Use the hook to open the bag, take the money and chisel, and use the chisel on the globe. The broken bottle provides another useful item, while the whiskey can serve as fuel. Enter 7427 on the generator panel, load the generator, and activate it.

Use the book and taser to disarm the guard. Release the girl and proceed to the final bridge confrontation. The fight is based on counters rather than traditional health management:

Opponent moveEffective response
PunchElbow or dodge
KickDodge or block when appropriate
ElbowKick
BlockAvoid wasting a counter; choose a safe action
DodgeUse a direct attack when the opening appears
StopDodge or use the correct attack response

Read each prompt before selecting an action. The successful sequence begins with a dodge, followed by a block and elbow pattern, then uses a kick at the correct opening. The final exchange requires matching the opponent’s move rather than repeating the same action. Winning the fight completes the story.

Completion Checklist and Reference Tables

Use this checklist before leaving a chapter. Most failed attempts come from moving forward without collecting a tool, skipping a message, or overlooking a small sparkling object.

Story Completion Checklist:

  • Enter 63849 at the police computer
  • Open the cabin with 40827 and the safe with 9416
  • Unlock the phone and collect the mailbox triangles
  • Disable the robot and enter elevator code 4365
  • Identify Dan and complete the phone-monitoring puzzle
  • Open the hideout with 991224 and finish the final fight
Backtracking Tip

When an item seems unusable, inspect earlier locations again. The phone cord, small key, screwdriver, and triangle pieces are designed to connect separate areas.

ChapterKey codesMajor puzzle focus
Chapter 163849, 40827, 9416Computer, cabin, tattoos, ice bridge, evidence
Chapter 24365Robot, EMP, elevator, shelf arrangement
Chapter 321-10-12, 5397, 40242Hard drive, computer, traitor, evidence room
Chapter 4991224, 7427Gate, drones, bridge, generator, final fight

The most important inventory chain is concentrated in Chapter 1. The snowblower opens the cabin route, the hacksaw exposes the safe, the lockpick gun opens the exterior door, and the fire extinguisher makes the burned vehicle searchable. The wrench and small key then connect the outside evidence box to the phone investigation.

In later chapters, prioritize items that change the environment. The EMP disables the robot, duct tape repairs the lamp, the rope reaches the key, and the chisel opens the globe. The final chapter is easier when every tool is collected before attempting the hideout’s deeper puzzles.
