Start With the Desk

Pick up the chip reader, place it on the desk, and inspect the bold numbers before using the computer.

Search Every Object

Examine the body, tattoos, phone case, loose floorboards, and nearby containers before leaving the cabin.

Return With Tools

The hacksaw, crowbar, wrench, screwdriver, and small key each unlock a later part of the route.

Route Advice

Inspect important clues before using tools. Several solutions depend on symbols, numbers, or messages that become visible only after close examination.

Chapter 1 Codes and Cabin Puzzles

The first chapter uses several direct combinations. Record each code when you discover it, then apply it only to the matching device. The most important clue chain begins at the desk and continues through the cabin, safe, phone, and mailbox.

1

Unlock the Computer

Take the chip reader from the box and place it on Kate’s desk. Inspect the reader and use the five bold numbers, 63849, on the computer.

2

Clear the Snow

Collect the wheel, nozzle, and fuel. Combine them with the snowblower, then use the repaired machine to remove the snow blocking the route.

3

Open the Cabin

Pick up the metal numbers and arrange them on the board to form 40827. Enter that sequence on the cabin keypad.

4

Solve the Safe

Move the mattress and rug, open the window, inspect the body, and examine the symbol strip. Count the arrow, skull, heart, and wave symbols as 9, 4, 1, and 6.

5

Assemble the Evidence

Use the safe contents to progress through the lockpick, phone, mailbox, triangle, and wall puzzles. Place the letter, chart, and photograph together to reveal the evidence.

Avoid Losing the Symbol Clue

The safe combination is not presented as a normal keypad clue. Count the symbols shown on the body and match them to the strip in the correct order: arrow, skull, heart, then wave.

Chapter 1 Item Order and Backtracking

The cabin chapter is easier when items are used in a deliberate sequence. Some objects appear useful immediately but must wait until another clue or tool has been collected. Use the table as a compact inventory route.

Inspect

Read numbers, tattoos, symbol strips, text messages, and charts before trying to solve the next device.

Collect

Take every clearly visible tool, including the wheel, fuel, hacksaw, cloth, and fire extinguisher.

Repair

The snowblower, wheelchair, and phone route each require a specific item before they become useful.

Revisit

Return to the cabin, car, mailbox, and wall display after unlocking new areas or obtaining tools.

Chapter 1 Progress Checklist:

  • Enter 63849 at the computer
  • Use the snowblower to clear the route
  • Enter 40827 at the cabin
  • Open the safe with 9416
  • Place the letter, chart, and photograph on the wall
Efficient Inventory Play

Keep track of tools by their likely target: cutting tools open barriers, repair tools restore devices, and clue items usually belong in a display or combination puzzle.

Chapter 4 Walkthrough and Code 7427

Chapter 4 shifts from the cabin evidence trail to a frozen building, a generator, and a timed combat puzzle. Start by collecting the spikes, clearing the signs, and taking the vodka from the trash pile. The frozen metal box can then be thawed with the vodka, revealing the bullet-hole clue.

1

Read the Bullet-Hole Signs

Brush the snow from the signs and inspect the thawed metal box. Use the number of bullet holes on each sign to read the clue sequence. The visible values are 99, 12, and 24.

2

Build the Crossing

Collect two beams, move the curtain, and take the hammer. Use the hammer to remove the planks, then add the beams, planks, and spikes to repair the passage.

3

Collect the Rings

Take the skylight rod and move the firewood to reveal another ring. Use the rod to retrieve the ring from above, then place all three rings in their matching positions.

4

Copy the V Pattern

Inspect the upstairs pattern and reproduce the V arrangement. The resulting code is 7427. Return downstairs and enter it into the locked duffel bag.

5

Restore Power and Rescue the Captive

Take the chisel and fight manual from the bag. Use the chisel and hammer on the mechanism, collect the broken bottle and syrup, then pour the syrup into the generator. Use the taser, take the key, and unlock the captive.

Chapter 4 Code Check

The duffel bag code is 7427, taken from the V-shaped pattern upstairs. Keep the order unchanged when entering the sequence.

Chapter 4 Fight Puzzle and Final Sequence

The final Chapter 4 encounter uses a fight manual with a limited move set. The objective is to knock the opponent down once in each of three rounds. Because the encounter is timed, review the move relationships before beginning instead of selecting actions at random.

RoundRecommended SequencePurpose
Round 1Dodge, block, elbowSurvive the opening exchange
Round 2Stab, then punchReact to the opponent’s defense
Round 3KickFinish before the opponent’s stab
Overall goalKnock the opponent down three timesComplete all three rounds

The fight manual indicates that each move can counter another move. Use the early actions to read the opponent’s pattern, then preserve the strongest response for the final exchange. The known route begins with dodge, block, elbow, continues through stab and punch, and ends with a kick that resolves the final round.

The broader Chapter 4 sequence is also important: retrieve the tools, reproduce the upstairs pattern, open the duffel bag, restart the generator, use the taser, and collect the key before starting the rescue and combat finale.

Q: What is the On Thin Ice appunwrapper computer code?

The Chapter 1 computer code is 63849. Find it by placing the chip reader on Kate’s desk and reading the five bold numbers.

Q: What is the cabin keypad code in On Thin Ice?

The cabin keypad code is 40827. Arrange the metal numbers on the nearby board to reveal the sequence.

Q: How do I open the Chapter 1 safe?

Enter 9416. Count the arrow, skull, heart, and wave symbols on the body in that order: 9, 4, 1, and 6.

Q: What is the Chapter 4 duffel bag code?

Use 7427. Copy the V-shaped pattern found upstairs, then enter the resulting code in the duffel bag.

Combat Preparation

Read the fight manual before starting the timed encounter. The safest approach is to follow the known sequence and avoid spending a useful counter too early.

Final Progress Review

Use this final route summary when checking a playthrough. It combines the major codes, tools, and objective transitions into one quick reference.

Progress PointVerify Before Moving On
ComputerChip reader placed and 63849 entered
CabinSnowblower repaired and 40827 entered
SafeSymbol counts converted into 9416
EvidenceLetter, chart, and photograph placed on the wall
Chapter 4V pattern converted into 7427
GeneratorSyrup added after the mechanism is opened
RescueTaser used and key taken
FinaleOpponent knocked down in all three rounds

The strongest approach is to examine every new scene before combining items. Adventure Escape Mysteries frequently places the answer in a visual detail, such as a number sequence, symbol order, bullet-hole count, or geometric pattern. When a puzzle appears blocked, revisit the previous room and inspect objects that became relevant after collecting a new tool.

For the Chapter 1 evidence route, keep the safe contents together: the letter, triangles, and lockpick gun each support the next set of interactions. For Chapter 4, preserve the relationship between the skylight rod, rings, upstairs pattern, and duffel bag. This keeps the story progression organized and limits repeated searches.

Completion Standard

A clean completion route includes all major codes, the recovered Chapter 1 evidence, the Chapter 4 rescue sequence, and three successful combat knockdowns.
