Multiball designed by Eric Fuller and crafted by Cubic Dissection.
This is one of Eric Fuller's classics! I remember back when it was first released a lot of people were solving it in an unintended way which made it way more difficult. Eric ended up posting a video on YouTube showing the elegant and super satisfying intended solution saying, "You guys are way overthinking this!" Such a funny and great memory, not to mention a great puzzle! I'm listing it because I acquired an extra copy in a recent trade and would like to pass it on to a new home, highly recommended!
