Twist the two halves of this sphericon and shift marbles to rearrange them until all like colored marbles are touching. It sounds easy until you realize that each twist changes the behavior of the marble track. It’s a quantum puzzle!!!
Because glass marbles aren’t consistent, I’m measuring individual marbles and printing the correctly sized astrolabicon based on those. That means the size of each puzzle varies every so slightly, but it is around 80mm from tip to tip. Any puzzle I sell has been tested and guaranteed to twist and slide, although you may have to give the puzzle the occasional shake to keep things from jamming.
Printed in biodegradable PLA plastic, with Neodymium magnets and glass marbles.
