| The original design of The Slider was done in the early 1960's.
The puzzle looks like a standard 18-piece burr (which I had not seen
before at the time I designed it). To unlock the burr, one needs to
move three pieces in different directions at the same time (coordinate
motion). I used slant cuts to enforce this.
In 2010 I decided to use this design as the basis for my souvenir puzzle.
The puzzle was made more difficult by adding a locking pin and magnet.
This was my souvenir puzzle at the 30th International Puzzle Party. |
