Z-Cube Albert Einstein Lock Puzzle

Albert Einstein Lock Puzzle

A padlock-shaped puzzle from the official Albert Einstein series published by Professor Puzzle. The Albert Einstein Lock Puzzle is a wooden padlock with a permanently attached metal key. The task is easy to explain but harder to do: you need to open the padlock by sliding parts of the lock. The key alone won't do it. First you have to figure out which parts can move and in what order.

How the lock puzzle works

This is not a twisty puzzle. You don't turn any layers here, and cube algorithms won't help you. The Lock Puzzle is a mechanical puzzle, where you find the solution through observation and trial. You need to check which part moves, what is blocking it and what changes after each move. Force won't get you anywhere, because the order of moves is what counts.

The key is attached to the padlock, so it won't get lost while you're solving or after you put the puzzle back on the shelf. The most exciting part is the first attempt, before you know the solution. After that, you can hand the puzzle to someone else to try.

Who is it for?

For anyone who enjoys logic puzzles and wants to try something different from yet another cube. The Lock Puzzle requires no prior knowledge, so it also makes a great gift for someone who doesn't solve puzzle cubes but likes a good brain teaser. If you're buying it for a child, keep in mind that solving it takes patience and a careful look at the mechanism. Randomly sliding the parts rarely leads to success.
