On Thin Ice escape room: Chapter 1 Route

The opening chapter introduces Kate Gray and Murphy during a ransomware investigation that quickly moves from the police station to a snowbound cabin. The safest route is to collect every visible tool, read each clue carefully, and avoid guessing codes before matching them to their source.

Video Highlights:

  • The police computer setup and the first five-digit code.
  • The snowblower, cabin keypad, body-symbol safe, and ice bridge sequence.
  • The phone, mailbox, triangle puzzle, and evidence recovery route.

Exploration Tip

Highlighted objects often provide both an item and a clue. Inspect screens, notes, tattoos, posters, and background details before leaving an area.

Police Station and Snowblower

Start by taking the chip reader from the box near Kate’s desk. Place it on the desk and inspect the computer display. The bold digits on the reader provide the first code: 63849. Enter the numbers into the police computer to unlock the investigation route.

Kate and Murphy then travel to Hacksaw’s snowy cabin. Before entering, collect the wheel, nozzle, and fuel. Combine them with the snowblower, then use the repaired machine to clear the snow blocking the cabin door.

The metal numbers beside the entrance form the next clue. Arrange them on the board according to the visible nail and arrow pattern. The correct cabin keypad code is 40827.

Cabin Investigation and Safe

Inside the cabin, move the mattress and rug, open the window, and collect the cloth curtains. Search the cabinets for the hacksaw and symbol strip. The loose floorboards conceal a safe, but it cannot be opened immediately.

Take the curtains outside and wet them in the puddle. Return inside and use the wet cloth to clean the blood from the safe. Then compare the symbol strip with the markings on the body:

SymbolCountSafe digit
Arrow99
Skull44
Heart11
Wave66

Enter 9416 to open the safe. Collect the letter, triangle pieces, and lockpick gun. Use the lockpick gun on the right-hand door to reach the outdoor area.

Burned Car, Phone, and Mailbox

Outside, remove the tarp from the grill and collect the fire extinguisher and cleaning oil. Use the oil on the rusted box, but wait until the small key is available before opening it. Extinguish the burning car, then search the bodies for a crowbar and wrench.

Use the crowbar to open the car door and take the phone cord. Return to the cabin, plug in the phone, and use the wrench to repair the wheelchair. The repaired wheelchair provides the small key. Take it back outside and use it on the rusted box to obtain the screwdriver and more triangle pieces.

Use the screwdriver on the hidden compartment in the body’s leg to retrieve the dead phone. Charge it on the wireless charger, then use Hacksaw’s face for facial recognition. Read the messages to learn about a package in the mailbox. Unlock the mailbox with the phone and collect the final triangles and chart.

Chapter 1 Checkpoint

Before solving the final cabinet puzzle, confirm that you have the letter, chart, photo-related clue, and every triangle piece. Missing one item usually means an earlier hidden compartment was skipped.

Chapter 1 Puzzle Solutions and Item Order

The first chapter rewards a deliberate item loop. Several objects cannot be used when first discovered because their required tool appears later. Use the following order to reduce unnecessary backtracking.

1

Unlock the police computer

Take the chip reader, place it on the desk, and enter 63849 from the bold reader digits.

2

Open the cabin

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

3

Open the body safe

Find the hacksaw, cut the loose floorboards, wet the curtains outside, clean the safe, and enter the symbol count 9416.

4

Recover the phone

Extinguish the car, collect the crowbar and wrench, repair the wheelchair, use the key on the box, and open the leg compartment with the screwdriver.

5

Finish the evidence puzzle

Charge the phone, unlock it with facial recognition, open the mailbox, place all triangles in the cabinet puzzle, and arrange the letter, chart, and photo clue.

Facial IDHacksaw’s bodyUse the face shown in the scene
Triangle cabinetComplete triangle setGuide the electrical dot to the yellow triangle

Triangle Cabinet Puzzle

Place all collected triangles into the cabinet board. The objective is to guide the electrical dot from its starting position to the yellow triangle on the far right. Each move rotates the triangle where the dot lands, so the route is determined by the changing orientation rather than by a fixed straight line.

If the board does not respond as expected, check whether a triangle from the mailbox or the hidden compartment is missing. The cabinet opens only after the complete set is installed and the electrical route reaches its destination.

Avoid a Common Mistake

Do not treat the safe code as a random four-digit combination. Count each symbol shown by the strip and match the categories in order: arrow, skull, heart, then wave.

Chapters 2–3: Investigation and Evidence

The middle chapters shift the focus from cabin survival to investigation. Kate and Murphy follow the ransom case, confront a dangerous office setup, and investigate a possible traitor inside the police station.

Chapter 2: Office Security and the Elevator

At the negotiator’s office, speak with the robot and study the highlighted dialogue clues. The required order uses the shield first, hourglass in the center, and no-talk symbol last. This opens the case containing the wire.

Combine the wire with the capacitor and power supply to create an EMP device. Use it to disable the robot. The computer-chip puzzle then requires rebuilding an image by matching corner pieces. Completing it opens the elevator.

The elevator code comes from the panel’s visual symbols. Match the button designs to the displayed digits:

Button designDigit
Black-and-white pattern4
Yellow with black marking3
Black frame6
Completely black button5

Enter 4365 to reach the negotiator’s office.

Inside, inspect the room and collect the hard drive, fan, rope, clamp, lamp-related items, and other display objects. Duct tape repairs the lamp, while the rope helps reach a key area. Arrange the objects on the shelves by matching their positions to the background display. Once the shelf puzzle is complete, the elevator route opens.

Chapter 3: Finding the Traitor

Back at the police station, inspect the hard drive and match the colored frame clues to the nearby tree and numbered signs. The sequence needed for the drive is 21, 10, 12. Connect the drive to the computer, then wake Dan by using the column and water-filled mug.

Build the computer with the two graphic cards, plastic tubes, coolant, and drawer handle. The password clue uses four symbols from the photo frame:

SymbolDigit
Clock5
Snowflake3
Fish9
Gear7

Enter 5397 to unlock the computer. Rearrange the colored rows so that yellow is on top, white is in the middle, and green is at the bottom. The contact book reveals the ringing phone and points toward Dan as the traitor.

The chapter then moves into the evidence room and detention area. Use sanitizer on the frozen panel, a bent wire to obtain keys, and police tape to clear an obstacle. The prisoner-count poster supplies a five-digit code based on hands, missing items, shirts, shoes, and mouths.

Investigation Note

Chapter 2 and Chapter 3 use visual ordering more often than direct number clues. Record the position of each symbol, color, and object before interacting with the final lock.

Chapter 4: Gate, Manor, and Final Fight

The final chapter sends Kate and Murphy to the location of the gang. The route combines a gate code, drone timing, rescue work, hidden-door mechanisms, and a combat-style response puzzle.

Gate and Drone Route

Use the vodka bottle to clear the frozen control panel. Read the three relevant posters and compare the bullet-hole counts with their numbers. The gate code is 991224.

Beyond the gate, move through the drone field while collecting the route markers. Wait for drones to rise or pass before crossing exposed spaces. A careful pace is more reliable than moving directly toward the next marker.

Manor Rescue and Hidden Door

Inside the manor, Murphy falls through a trap. Collect the planks and wooden blocks, then use the hammer to build and secure a bridge. The hidden chimney door requires three rings. Find the missing rings with the hook and beneath the firewood, then place all three into the mechanism.

The visible clue uses the letter pattern V, W, X, K. Recreate the same arrangement on the ring mechanism to open the hidden passage.

Rescue MurphyPlanks, blocks, hammerBridge is secured
Open chimney passageThree rings, hookHidden door unlocks
Access generatorChisel, code clueGenerator can be operated
Disable the final threatBook and taserKate can free the captive

Generator and Captive Rescue

Separate the three culprits one at a time. Search the first area for money and a chisel, then use the chisel on the globe to obtain whiskey. The whiskey functions as fuel for the generator. Enter the displayed generator code, 7427, and operate the damaged machine.

The generator route provides access to the equipment needed to disable the remaining threat. Use the book and taser found in the backpack, then release the captive and prepare for the final encounter.

Timing Tip

The drone section is a movement test, not a code puzzle. Watch the flight pattern, pause in safe positions, and collect markers only when the path is clear.

Final Encounter, Checklist, and FAQ

The final fight uses a response chart rather than conventional combat statistics. Each action counters another action, so read the available move relationships before selecting a response.

The useful relationships are:

  • Kick defeats elbow.
  • Elbow defeats punch.
  • Punch defeats kick.
  • Dodge avoids several direct attacks.
  • Block counters the stop action.
  • Stop defeats dodge.
  • Dodge defeats block.
  • Some actions are ineffective against their own counter, so do not repeat a move without checking the opponent’s choice.

The encounter is presented in multiple rounds. A practical sequence includes dodging when the opponent threatens a direct attack, using block against stop, and selecting kick against elbow. If a round fails, review the response chart instead of treating the result as a lost item or permanent penalty.
