Build a decoy chest that pranks thieves, and an alarm on the real loot.

A thief spots a lonely chest and grins. Bad move. It's a decoy, and the real loot is guarded by a sensor.

What you’ll build

Set out a decoy chest that spits silly GOTCHA books at anyone who opens it. Then hide the real loot in a chest watched by a comparator and a torch, so an alarm rings the moment it's emptied. Invite a thief and see which trap catches them.

Finish line: Your decoy chest pranks thieves with GOTCHA books, and the real loot raises an alarm when it's emptied.

Bonus challenge: Hide a lever that switches off the loot alarm, so only you can take the treasure in silence. Where's the last place a thief would look?

You’ll need

  • Trapped chest
  • A dropper
  • Written books
  • A chest and comparator
  • Redstone torch
  • Note blocks

You choose

  • What the decoy pretends to hold
  • The prank prize it spits out
  • Where the real loot hides

Stuck?

  • The alarm only fires when the real chest is completely empty: one item left keeps it quiet.
  • The comparator must point out of the loot chest into a solid block, with the torch on the far side.
  • Use a trapped chest for the decoy: an ordinary chest sends no signal when opened.
