On Thin Ice Puzzle Solutions: Chapter 1
The opening chapter moves from the police station to Hacksaw’s snowy cabin. Search every interactive area before entering a code, because several clues are found on objects that initially look decorative.
Video Highlights:
- Chapter 1 cabin exploration and item collection
- The symbol-count safe and ice stairway puzzle
- The phone, mailbox, and triangle puzzle sequence
| Puzzle | Solution | Where to use it |
|---|---|---|
| Police computer | 63849 | Enter after scanning the chip reader |
| Cabin keypad | 40827 | Unlocks the snowy cabin |
| Symbol safe | 9416 | Arrow, skull, heart, wave counts |
| Mailbox | Phone unlock | Use the dead man’s face for facial ID |
Start by taking the chip reader from the box and scanning the highlighted numbers on the desk. Enter 63849 into the computer. At the cabin, repair the snowblower with the wheel, nozzle, and fuel, then clear the snow from the entrance.
Arrange the metal numbers according to the nail positions to create 40827. Inside the cabin, collect the curtains, hacksaw, symbol strip, and other visible clues. Move the mattress and rug, open the window, and use the hacksaw on the loose floorboards to reveal the safe.
Wet the curtains outside, then use them to clean the blood from the safe. Count the symbols shown on the strip:
| Symbol | Count | Safe digit |
|---|---|---|
| Arrow | 9 | 9 |
| Skull | 4 | 4 |
| Heart | 1 | 1 |
| Wave | 6 | 6 |
Enter 9416 to obtain the letter, triangles, and lockpick gun. Use the lockpick gun on the right-hand door. Outside, collect the fire extinguisher and cleaning oil, then use the extinguisher on the burning car.
Do not leave the cabin after finding the phone. Charge it first, unlock it with Hacksaw’s face, and read the messages before checking the mailbox.
Use the crowbar from the body to open the car door and collect the phone cord. Repair the wheelchair with the wrench to receive the small key. Use that key on the rusty box outside, then take the screwdriver and additional triangles.
Place the phone on the charger, unlock it with facial ID, and follow the delivery clue to the mailbox. The mailbox contains the final triangles and chart. Place all triangles in the cabinet puzzle and guide the electrical dot to the yellow triangle. Finally, put the letter, chart, and photograph on the wall to open the hidden safe and secure the hard drive.
Chapter 2 Codes and Escape Puzzles
Chapter 2 shifts to a hostage negotiation office filled with electronic security devices. Inspect the robot’s dialogue carefully, since its highlighted words provide the order for the first lock.
The robot puzzle depends on position, not just symbol matching. Reproduce the order as shield first, hourglass center, no-talk symbol last.
| Puzzle | Correct solution | Result |
|---|---|---|
| Robot case | Shield / hourglass / no-talk | Reveals the wire |
| Elevator keypad | 4365 | Opens the elevator |
| Shelf puzzle | Match background silhouettes | Clears the exit |
| Final route | Swap square tiles | Creates paths for Kate and Penny |
Talk to the robot and use the wire, capacitor, and power supply to build the electromagnetic pulse device. Place it correctly to disable the robot. Collect the computer chips and complete the image by identifying its corners.
The elevator keypad uses four visual patterns. Match each button to the corresponding example beneath the panel. The correct sequence is 4365.
In the office, collect the hard drive, fan, lamp, rope, key, clamp, and other visible items. Repair the lamp with duct tape, use the rope to reach the higher area, and use the clamp to obtain the final shelf object. Arrange the objects by matching their silhouettes in the background.
| Item clue | Action |
|---|---|
| Duct tape | Repair the lamp |
| Rope | Reach the elevated area |
| Clamp | Retrieve the final object |
| Key | Open the safe |
| Shelf objects | Match the background arrangement |
Once the shelf puzzle is complete, use the tile-swapping puzzle to create connected routes for both characters. Check both paths before proceeding, because a single misplaced square can block the exit.
Collect every item in the office before solving the shelf puzzle. This reduces backtracking and makes the final tile path easier to verify.
Chapter 3 Investigation Solutions
Chapter 3 returns to the police station and focuses on identifying the traitor. The main sequence combines a hard-drive password, a sleeping technician, a contact list, and a monitoring device.
Open the hard drive
Match the colored frames with the tree image, then use the numerical clue to enter 21, 10, 12.
Repair the computer
Collect two graphics cards, the drawer handle, plastic tubes, and coolant. Assemble the computer and connect it to the monitors.
Enter the computer password
Use the photo-frame clue to match the symbols: clock 5, snowflake 3, fish 9, and gear 7. Enter 5397.
Find the traitor
Rearrange the colored rows so yellow is on top, white is in the middle, and green is at the bottom. Take the contact book and use it to identify the ringing phone.
The hard-drive puzzle uses three number clues connected to colored frames. After opening it, wake the sleeping technician by using the column and then assemble the computer with the two graphics cards and coolant.
| Password symbol | Digit |
|---|---|
| Clock | 5 |
| Snowflake | 3 |
| Fish | 9 |
| Gear | 7 |
Enter 5397 to access the computer. The row puzzle is solved when the colors appear in this order from top to bottom: yellow, white, green. The resulting contact book points to the ringing phone and identifies Dan as the suspected traitor.
After the interrogation sequence, clear the holding area with the sanitizer and bent wire. Use the wire to retrieve the keys, then clean the frozen panel and inspect the poster clue.
When checking the prisoner’s belongings, inspect the code panel after cleaning it. The poster counts hands, items, shirts, shoes, and mouths to produce the required five-digit entry.
The monitoring puzzle uses a battery pack, antenna, and connected hexagons. Begin with the hexagon marked 6, since it must connect on all six sides. Then place pieces with fewer available connections and fill the remaining gaps without breaking the numbered links.
Chapter 4 Final Area and Combat
The final chapter takes Kate and Murphy to the enemy’s snowy compound. The route combines a gate code, timed drone movement, a hidden-door combination, and a final fight.
| Area | Solution | Key action |
|---|---|---|
| Compound gate | 991224 | Read the bullet-hole posters |
| Hidden door | Match the VWXK pattern | Place the three rings |
| Generator | 7427 | Enter the code from the bag |
| Final fight | Dodge, block, elbow, kick | Follow the counter pattern |
Use the vodka to clear the frozen gate panel. The posters show one bullet hole with 99, two with 12, and three with 24, producing 991224.
After entering the compound, move between the drone paths and collect the markers during safe openings. When Murphy falls through the floor, collect planks and wooden blocks, then build the bridge with the hammer.
Find three rings for the hidden door. One is already available, one can be reached with the hook, and another is hidden beneath the firewood. Arrange the rings to copy the VWXK clue.
Do not rush between markers. Wait for the drone to move high or away from the next marker, then cross the open route before collecting it.
Separate the enemies by opening the door and searching each area. Use the chisel on the globe to obtain whiskey, which serves as fuel. Take the broken bottle, generator clue, and red triangle. Enter 7427 into the generator and repair it before disabling the guard with the book and taser.
For the final fight, use the counter relationships shown in the fight guide. The useful sequence is dodge first, then block, elbow, and kick when the opponent’s move requires it. Avoid wasting a turn blocking an attack that does not need a counter.

For additional chapter context, consult the Adventure Escape Mysteries – On Thin Ice walkthrough guide. The most reliable approach is to inspect every object, record codes immediately, and solve visual arrangements only after collecting all nearby pieces.
If a puzzle appears incomplete, search the current scene again for an item that changes the interaction. On Thin Ice frequently gates the next solution behind a tool collected moments earlier.
