Expert Puzzle Locks

These are not puzzles for the faint-hearted.

The DanLock and the Loki are the two most challenging puzzles in the Puzzlocks collection. Both are sequential discovery puzzles, meaning they unfold in stages. Each step reveals something new, and getting through all of them requires patience, focus, and a willingness to start over when you think you have it figured out.

These are the puzzles that experienced solvers talk about. The ones that stay on the desk for days. The ones people hand to friends just to watch them try.

Puzzle Difficulty Average Solving Time Price
DanLock Intermediate to Expert 10 hours $199
Loki Expert 18 hours $219

The DanLock was originally crafted in 1996 by Dan Feldman and has been called the best puzzle lock ever made by enthusiasts around the world. If you are buying one expert puzzle as a serious gift, this is the one most people remember forever.

The Loki is our most challenging puzzle. 18 hours is the average. Some people take longer. Nobody gives up easily. That is the whole point.
