The magnetic parts attach seamlessly to all ferromagnetic materials-like your fridge, a locker or a whiteboard, for example. Simply move the track, connector and trick pieces around for an exciting brand new marble challenge. 

We’re two industrial designers with backgrounds in woodworking and engineering who set out to create a fun, never-ending, always-engaging super-puzzle.

We wound up with an extensive system of modular magnetic units that we just can’t keep our hands off of. So we decided it was time to share the fun and excitement with you all.
