Give someone the chance to feel like a genius from ancient Greece with the Project Genius Grecian Trick Lock Puzzle.

Inspired by the clever designs of Theodorus of Samos, this puzzle brings back one of history’s most secure locking mechanisms in a brain-teasing form.

It’s a great pick for anyone who loves solving things that look simple but aren’t!

You’ll receive a beautifully crafted lock and key, but turning the key won’t be enough...

This trick lock is full of surprises, and it’s up to the puzzler to work out what’s really going on inside! 

Great for ages 8 and up, this is a fun way to give someone a puzzle with a twist of history.

It looks great on display, feels nice in the hand, and delivers a satisfying challenge that doesn’t rely on screens or instructions.

  • Based on the original Greek warded lock design  
  • Includes metal lock and key with hidden trick  
  • Suitable for ages 8 and up with a 3/5 difficulty level  

Wrap one up for the curious mind in your life - it’s a clever gift that’s sure to get them thinking.

My goods were exactly what I expected, I was told exactly where my parcel was and how long it would take to get to me. Everything was just so cool, as the name suggests. Love your stuff, it's so different....
