Livewire Puzzles has been making and selling puzzles since 1979. They are a home-based business located in Edmonton, Alberta, Canada. They specialize in the production and sales of wire disentanglement puzzles. This is the puzzle type where the goal is to separate two interlocked parts, most often a ring or a handle, from the main body of the puzzle. Our puzzles vary in difficulty. Some are suitable for those who prefer less of a challenge, while others are much more complicated and intended more for the serious puzzler. They also have several medium-difficulty puzzles that lie in between the two extremes.

Puzzle World contains information about many of the finest handcrafted mechanical puzzles in the world. Most of the puzzles presented here are not the mass-produced variety found in stores, but limited production puzzles designed by the foremost puzzle designers in the world and produced by craftsmen (often the designers themselves) working primarily in wood. However, to provide representative examples of all the different puzzle categories, mass produced puzzles are often the only ones available and will be included. Many of the puzzles are available directly from the designers, craftsmen, in stores or from catalog sales. Some craftsmen have provided information about puzzles they have available on their designer/craftsman page.
