Build a mirrored room with 5 mistakes. The twinless button is the exit.
Everything in this room has a twin on the other side. Everything except one button… and that's the way out.

What you’ll build
Build a room split down the middle by a glass mirror line, with everything copied to the other side. Sneak in a few mistakes and one lonely button with no twin, wire only that button to the exit, and see who escapes.
Finish line: Your mirror room hides five mistakes and one lonely button that opens the exit.
Bonus challenge: Build a second room with spin symmetry: every quarter matches when turned 90°. Hide one odd quarter for testers to spot.
You’ll need
- Glass
- Buttons
- Redstone dust
- An iron door
- Matching blocks for both halves
You choose
- My room's theme (haunted, palace, lab)
- My mirror line: X =
- Where the real button hides
Stuck?
- Mirroring gets confusing? Count blocks out from the glass line and copy the same count on the other side.
- Iron doors only open with redstone. Hide the dust under the floor or behind a wall.
- Decoy buttons do nothing. Just make sure no dust runs near them.
