Welcome to Rob's Puzzle Page - an on-line mechanical puzzle collection / puzzle museum.

I maintain this site to report on the world of mechanical puzzles, to have fun, and share information with my family, friends, and other puzzle-people. In addition to lots of pictures of puzzles, you'll find information about puzzles, many pointers to where to get them, and some help with how to solve them.

Explore using the menu at the left of this (and the bottom of every other) page, the classification page, or the site map. If you've got JavaScript enabled, you should also see my "ring menu" above. If not, you won't see the headers or menus on the sub-pages.

I have been collecting mechanical puzzles (aka brainteasers, Geduldspiele, casse-têtes, hlavolamy, puslerier, puzzels, rompecabezas, パズル, головоломка, 难题, الألغاز, σπαζοκεφαλιά, פזלים, ลูกบิด, पहेली, uganke, gestaþraut ) for many years and from many places. I have been asked, "Don't you have enough frustration in your life?"  Evidently not...

See what's new!   Or, ( this site only) for: 

At last count, there are 5067 puzzling items (including over 230 puzzle-related books) shown or described. That may seem like a lot, but there are people who own tens of thousands of puzzles - and who must have very understanding spouses!

I like most kinds of puzzles, and I really enjoy interlocking puzzles, hidden-mechanism/secret-opening boxes, and tanglement puzzles. Write to me at , and we can discuss puzzling!

I have solved some puzzles by writing computer programs. Clever and useful free software is out there on the web, particularly BurrTools by Andreas Röver, SBPSolver by Pierre-Francois Culand, and Jürg von Känel's burr puzzle solver site. There are many links to U.S. patents on this site - to view them (USPTO instructions here) you'll need a TIFF plug-in for your browser. You can try AlternaTIFF. You might also want to search the European Patent Office. I have reduced the images to make them load faster, using Brett Kuehner's marvelous tool "PictureTray."


I have collected some of the images from various places on the web and in some cases show them without attribution. If you have concerns regarding my non-commercial use of your photo for this site, please let me know and I will take down your photo and replace it with my own.
