Level 3 - Locked Apartment
Video Walkthrough
Objective
Escape from the locked apartment by collecting items, solving puzzles, crafting tools, and navigating through the apartment's rooms. This level introduces lighting mechanics, chess puzzles, combination locks, pipeline puzzles, and multi-room navigation in an apartment setting.
Step-by-Step Solution
- Start in the dark apartment room - collect the broom from the shelf on the right side
- Use the broom on the switch located on the same side to clean it and collect a chip (1 of 5)
- Click on the switch to turn on the lights and illuminate the room
- Look up at the lampshade hanging from the ceiling in the center - collect Chip 1 from it
- Examine the armchair positioned to the right of the table - zoom in and collect Chip 2 hidden on the cushion
- Inspect the floor rug in the left corner of the room - lift up the corner to reveal Chip 3 and a match underneath
- Check the center of the table - collect the sleeping pills container
- Examine the stack of books on the table - collect the rope that is wrapped around them
- Look at the chair to the left of the table - notice the broken leg standing upright and collect it
- Approach the fireplace and use the chair leg to push aside the coal in the firebox
- Once the coal is moved, collect the handle and queen chess piece that were hidden underneath
- Turn your attention to the decorative box sitting on the couch - use the queen chess piece on it to activate the chess puzzle
- Solve the chess puzzle by repositioning the queens so that no two queens can attack each other - they must not share the same row, column, or diagonal
- Rearrange the queens: move the queen from E7 to E6, move B6 to B8, relocate C8 to C1, and shift G2 to F2
- Collect Chip 5 (the last chip) after completing the chess puzzle
- Go to the window at the back wall of the room and attach the handle you collected
- Interact with the window again to close it - closing the window causes the snow outside to melt, revealing a hidden box below
- Interact with the box that appeared - you'll need to use your collected chips to unlock it
- A color-matching puzzle appears - place each colored chip onto the circle that matches its color (the specific order may differ for each player)
- Once all chips are correctly placed, a hidden compartment automatically slides down, exposing a magnet - add it to your inventory
- Open your inventory and combine the magnet with the rope to create a magnetic retrieval tool
- Locate the fish tank sitting on the chest of drawers to the left of the window - use your magnet on rope to fish out a key from inside the tank
- Use the key on the door on the right, then click the handle to open it and enter the kitchen
- Explore the kitchen area - start by collecting the newspaper lying on the kitchen table
- Open the refrigerator/freezer unit and check the top freezer compartment to find frozen meat
- Notice the keys hanging on the back of a chair - take them and use them to unlock the left drawer, then collect the knife inside
- Kneel down and look under the sink - collect the rubber gloves from there
- Find the trash bin also located under the sink - tip it over, clear away the garbage, and retrieve the fuse hidden at the bottom
- Go back to the main room and examine the striped cushion on the armchair - use your knife to cut it open and find a key inside
- Take this newly found key to the door on the left side of the room - using the key reveals a complex mechanical lock puzzle
- Solve the lock puzzle by sliding bars and moving screws up and down in the correct sequence
- Slide bar 2 to the left to move screw B and C up, then slide bar 1 all the way to the left
- Slide screws A, B and C down, move bar 3 as far left as possible, move screws D, E and F up, then move bar 2 all the way to the right
- Slide screws D, E and F down, slide screw H up, move bar 4 as far right as possible, move screw I up, then move bar 3 all the way to the left
- Slide screws G, H and I down to move bar 4 all the way to the right and open the lock
- After opening the lock, you'll see a fuse box - take the fuse from your inventory and install it in the top slot
- Put on your rubber gloves for safety, then turn the fuse switch - this activates the electrical system and lights up the room
- Now that the room is illuminated, you can enter it
- Search the room and find a brown toolbox positioned on the right side - open it and take the screwdriver
- Approach the clothes dryer and while wearing your rubber gloves, safely pull out the electrical plug from the wall
- Open the dryer door and remove the clothes inside - check the pocket of one of the garments to find a screwdriver bit
- Examine the dryer's power cord - use your knife to cut it and collect the plug with attached wire
- Head back to the kitchen and locate the microwave - use the plug with wire on the microwave's damaged cord
- Carefully connect the wire pieces together by clicking multiple times until they're properly joined, then plug it into the wall socket
- Place the frozen meat inside the microwave and securely close the door
- Look at the top right corner of the microwave - there are control dials that you can adjust
- Study the four cups on the kitchen table and observe the positions of their handles - set the microwave dials to match these handle positions exactly
- Setting the dials correctly unlocks the button pad at the bottom of the microwave
- Press the buttons on the pad and watch as different colored lights illuminate
- Recall the clue you saw earlier - when you collected the screwdriver bit from the clothes pocket, there was the word 'MICROWAVE' written above it, with the letters 'WAVE' highlighted in specific colors: red, green, orange, and purple
- Press and hold the buttons that correspond to these four colors - specifically the three buttons on the right side and the one in the middle position
- The microwave door automatically opens - take the sleeping pills from your inventory and sprinkle them onto the meat
- Interact with the meat one more time to complete the preparation and create the sedated bait
- Make your way back to the room where the dog is located - use the prepared meat bait on the dog, which will cause it to fall asleep
- Collect the wood from the left side of the dog
- Collect the kettle from the top shelf at the back of the room
- Go back to the main room where you started and approach the fireplace
- Build a fire by first placing the newspaper, then adding the wood, and finally lighting it with the match
- As the fire burns, it reveals a hidden picture that was concealed above the fireplace
- Navigate to the left side room and examine the safe sitting on the table
- The safe has a four-digit combination lock with visual clues displayed on top - symbols of a hat, horse, bird, and snake
- To find the code, carefully count how many of each symbol appear in both the picture hanging at the back of this room and the picture you just revealed above the fireplace
- Based on your count, enter the four-digit code: 5 (hats), 8 (horses), 7 (birds), 2 (snakes) - which is 5872
- Collect a valve from the top shelf and a battery from the bottom shelf
- In your inventory, assemble the electric screwdriver by combining the screwdriver base, the screwdriver bit you found, and the battery
- Return to the kitchen and look up at the ceiling - you'll see a ventilation grill
- Use your newly assembled electric screwdriver to remove the screws holding the grill in place - once removed, collect the key that was hidden inside
- Go back under the sink and examine the control panel on the left side
- Install the valve you collected into the panel - this activates a plumbing puzzle
- Solve the pipeline puzzle by rotating pipe sections to create a continuous water path from the inlet on one side to the outlet on the other (note: the specific pipe configuration may vary between game sessions)
- Once the path is complete, turn all the valves to the open position to activate the water supply
- Take your empty kettle to the kitchen sink and position it under the tap - turn on the tap to fill it with water
- The kettle is now filled - add it to your inventory as 'kettle with water'
- Locate the stove at the back wall of the kitchen and turn on the burner
- Set the filled kettle on top of the hot stove burner
- Allow the water to heat up for a few seconds, then interact with the kettle to collect it as 'kettle with boiling water'
- Go back to the room where the sleeping dog is and approach the window on the right side
- Use your knife to chip away at the thick ice that has formed at the top of the window frame
- Pour the boiling water from your kettle onto the frozen lock mechanism - the heat will melt away the remaining ice
- Now that the lock is accessible, insert the key you collected from the ceiling grill and turn it to unlock the window
- Open the window and climb through to escape, completing Level 3 - Locked Apartment
💡 Tips & Tricks
- The room starts dark - you must light it up first by cleaning the switch with the broom
- Keep track of all 5 chips - they're needed for the color-matching puzzle
- The chess puzzle solution is the same for everyone - follow the specific move sequence
- The chip color puzzle order may vary, so match colors carefully rather than following a fixed sequence
- The lock puzzle requires careful sequencing of bar movements and screw positions
- The microwave dials correspond to the cup handle positions on the table - observe them carefully
- The microwave button colors match the 'WAVE' colors from the word above the pocket (red, green, orange, purple)
- The safe code (5872) is found by counting objects in the pictures - hat, horse, bird, and snake
- The pipeline puzzle may vary, but always requires creating a complete path from one side to the other
- You need boiling water to melt the ice on the window - make sure to heat the kettle on the stove
- Some items like the chips are hidden in unexpected places - check cushions, rugs, and lampshades thoroughly
- The dog must be put to sleep before you can collect items from that room
