Give someone the joy of frustration with a historical twist - the Project Genius Latch Lifter Trick Lock Puzzle!

It might look like an ordinary padlock, but don’t be fooled, this Roman-inspired challenge has zero intentions of opening without a brain workout.

Modelled after the original latch lifters used by ancient Romans, this clever contraption was once used to sneakily lift door bolts from outside.

Now, it’s here to toy with your logic and patience. It comes with a key, but the solution isn’t as simple as turning it!

You'll need to figure out the right moves to lift the latch and unlock your pride. This is a great gift for someone who enjoys puzzles that fight back! 

It looks great on display, feels satisfying to handle, and gives just enough challenge to make victory sweet.

Perfect for ages 8 and up, and especially good for people who think they’re clever.

  • Inspired by the Roman latch lifter mechanism
  • Made from durable metal with a classic key
  • Rated 4/5 difficulty for a rewarding challenge

Wrap it up for someone who thinks they’ve seen it all - this puzzle will keep them guessing!
