From Cubic Dissection:Tom hits it out of the park again. This tricky little construct takes a simple yet interesting cage and seven identical pieces to create a 31 move masterpiece. There are rotations, but they won't help you. There is a lot of movement, but it won't help you. There is one and only one way to get all seven pieces in to this cage...the first six go pretty easy. The seventh takes 31 very specific, linear moves. Many times a puzzle like this can be as much a dexterity assembly as ...

This 6-piece burr is level 8.3.2.2. It has 105 theoretical assemblies, but only one can actually be constructed. This puzzle can be sent assembled or disassembled, your preference.

This 6-piece burr consists of three identical pieces plus three mirror image pieces. It is level 4.2.2.2.2. It is more difficult than the level would indicate, due to the unusual final shape, as well as the fact that many pieces are moving together in the final (or first) 4 moves.There are several versions of Karin's Outline Burr, this is not the most difficult one (made by Eric Fuller). I am not sure if this was the version exchanged at IPP21.
