Step-by-step walkthrough

01

Start the episode

Start in the living room. Pick up the key from the table and unlock the front door so the police officer can leave. Go into the kitchen and take the magnet stuck on the refrigerator door. Enter the child's bedroom, open the small backpack pocket, and collect a roll of electrical tape. Return to the living room and repair the cut TV cable with the tape. Note the phone number shown on screen—you will need it later. Step into the backyard, try the shed door (it stays locked for now), then open the outdoor electrical box and collect the metal handle inside. Use that handle on the stuck drawer under the TV. Take the spare fuses and a pair of pliers from the drawer. Back in the child's room, use the pliers to pry open the closet door and grab the mop hanging inside. Slide the mop under the bed to fish out a turn key. Use the turn key on the puzzle box by the window, rearrange the tiles until the picture is complete, and collect the gears figurine.

02

Continue the item chain — phase 2

Use the pliers again on the large backpack zipper. Take the first ruby and a knife from the pocket. Return to the backyard electrical box, replace the burned fuses with the new ones, then solve the shed-door mechanism (pattern layouts can vary) to open it. Inside the shed, collect a fishing rod and a ladder. Place the gears figurine on the toolbox lock to open it and take a screwdriver. Combine the magnet with the fishing rod in your inventory to make a magnetic rod. Lean the ladder against the tree, climb up, and collect a length of wire plus a funnel. Use the knife to unlock the child's play shed. Inside, take the second ruby and a wrench. In the kitchen, pull aside the red curtain under the sink and loosen the plumbing with the wrench to free the third ruby. Back in the backyard, unscrew the metal grill covering the pool drain with the screwdriver and climb down into the Other World.

03

Continue the item chain — phase 3

In the mirrored world, search the garbage pile for a signpost. Cut open the blue trash bag with your knife to find a lock insert. Fit the insert into the gate lock, solve the sliding or rotation puzzle, then lay the signpost across the gap as a makeshift bridge and cross. At the cafe parking area, open the car trunk and collect a rope and a crowbar. In the garbage lot, pry open the wooden crate with the crowbar to get a jerrycan and a scrub brush. Use the rope to climb down the hole. Near the stairs below, scrape away the leaves with your knife to find a medallion. Approach the red monster carefully and pick up the joystick lying nearby. Climb back to the garbage area, place the medallion on the statue, solve its puzzle, and collect the fourth ruby plus a flashlight. At the cafe payphone, dial the number you saw on the TV at home. Collect the coins that drop. At the fuel pump, insert the coins and use the empty jerrycan to buy gasoline. Pour the fuel into the generator through the funnel and start the machine. With power restored, take a game cartridge and a key from the snack machine.

04

Continue the item chain — phase 4

Use the magnetic fishing rod on the drain grate near the cafe entrance to pull up another key. Unlock the cafe game-room door, plug in the joystick, clear the mini-game on the arcade cabinet, and collect the remote control. Grab the oil can beside the machine. Return to your backyard barbecue. Oil the stuck latch, open the grill, and take a handle plus a box of matches. In the child's closet, unlock the small box with the cafe key. Collect the fifth ruby, a toy car, and a feed container. In the cafe kitchen, pour bottled water into the kettle and light the stove with matches to boil it. Take the hot kettle. Back home in the kitchen, use the barbecue handle to open the fridge. Pour boiling water onto the frozen meat, then cut a slice with your knife. Wire the meat slice onto the toy car so it becomes bait on wheels. In the living room, insert the snack-machine cartridge into the console, clear the on-screen puzzle, and collect spare batteries plus the sixth ruby.

05

Complete the escape

Combine the remote control with the fresh batteries and pair it with the toy car so you can drive it remotely. Place all six rubies into the shelf box and solve the gem-path puzzle (routes may differ slightly between playthroughs). Collect the special game cartridge inside. In the child's room, load the cartridge into the handheld console. Follow the directional prompts to clear the mini-game, open the tank, pour in the feed, and retrieve a UV lamp bulb. Install the UV bulb into your flashlight. Shine it on the wall drawings in the child's room and memorize the revealed code: 495. Return underground to the Other World and release the remote-controlled toy car as bait. Inside the pharmacy area, collect baking soda and a soft drink. Enter code 495 on the locked case to obtain a syringe. Pour the baking soda and soft drink onto the rusted escalator cover, scrub it clean with the brush, then solve the block-path puzzle—guide only one block to the finish, not all of them. Ride the escalator up, pry the doors open with the crowbar, cut the cabinet seal with your knife, and draw poison into the syringe. Approach the monster and inject the poison. Once it collapses, rescue your child and complete Level 25; Other World.

Before you leave this episode

The sequence includes every item required to finish the episode. Optional morphing objects and bonus collectibles are not needed for the exit. If the final transition does not start, reopen the most recent close-up and confirm that every required inventory item was used rather than merely collected.

Notes and precautions

This guide is mapped to Tricky Doors Level 25, “Other World.”
Complete inventory actions in order; later objects often remain inactive until an earlier mechanism is solved.
If an item will not combine, return to the scene where the game first introduced the matching clue.
The episode ends only after the final portal, vehicle, door, or story transition activates.

Useful solving habits

1Rotate your attention between the full scene and close-up panels; small tools are often hidden at the edge.
2Keep written recipes, symbol patterns, and color orders available until the related lock is complete.
3Inspect inventory objects directly because many tools must be assembled before they can be used.
4For randomized minigames, follow the stated rule instead of copying one fixed board layout.
