Oskar's hysteresis mazes
This puzzle is based on an original mechanical puzzle by Oskar van Deventer. Navigate the maze using east/west movement only and use the sloping walls to push the ball north/south. Later mazes include special yellow switch points where you can choose between horizontal or vertical movement Your choice will stay in force until you reach another switch point.
Update May 2024: Hysteresis Key has been rebuilt using the PSNext fork and now includes SVG sprites. This is one of the first published PS apps to include elements of SVG, thanks to the pioneering work of Henri Manson (April 2024).
The photo on the right shows the original Hysteresis Key puzzle designed by Oskar. Here the red key and blue 'rocker' interact to create the maze. Thanks to careful design of the maze the key slides easily into the lock but removing it again is quite a different matter
