Lost Labatory

The Lost Laboratory is a atmospheric point-and-click escape room game built entirely in a single HTML file — no

  installation, no download, just open and play in any browser.

 

  You wake up on the cold floor of an abandoned laboratory. The air smells of chemicals. The lights flicker. You don't

  know how you got here — but you know you need to get out.

 

  ---

  Your escape leads you through 10 increasingly difficult rooms, each with its own unique puzzle mechanics, atmosphere,

  and secrets:

 

  - Lab — Your starting point. Hidden keys, locked cabinets, and a cryptic whiteboard set the tone.

  - Storage Room — Combine items to craft tools. A locked safe stands between you and the next area.

  - Server Room — Assemble electronic components and hack a terminal to reveal an access code.

  - Archive Room — Decode clues hidden across the room, repair a shredded keycard, and unlock a heavily secured door.

  - Reactor Chamber — Power up a dead terminal with a salvaged fuse, crack a locked drawer, and assemble a 5-digit

  override code from two separate sources.

  - Medical Bay — Treat a suspicious wall with chemical spray, then reveal a hidden UV code under black light.

  - Machine Hall — Repair three broken industrial machines using the right components. Each machine reveals part of a

  5-digit activation sequence.

  - Final Exit — Power up a radio transmitter, decode an encrypted signal using a cipher book, and enter the 6-digit

  code on the final door.

  - Freezer — Read temperature gauges for a cabinet code, melt a frozen ice block with a heat rod, and retrieve the key

  locked inside.

  - Surveillance Room — Read active monitor displays for a panel code, salvage a chip from a broken screen, combine it

  with a signal decoder, and use the result to unlock the final exit.
