Rover Variation II - Andreas Rover by The New Pelikan Workshop

Here’s Andreas’ description:

“This has been my exchange puzzle for the IPP 31 in Berlin. It is my contribution to the realm of 6-piece burrs.

Each piece of the puzzle is made out of 2 units: a 6-piece burr shape. The one with the fewest cubes. If you look at this catalogue of 6-piece burr pieces it is piece 1023. The other unit is the L-tetromino.

There are 68 possible ways to connect those 2 units when you want to use the resulting shape in a normal 6-piece burr. Some of those shapes do have cubes outside of the 6x2x2 brick of the normal 6-piece burr shapes.

The 68 pieces can be assembled in 6213 ways into a 6-piece burr. 666 of those assemblies can be taken apart.

The highest level of all those solutions is level 6. There is only one set of pieces with a level 6 and this set is presented as this puzzle.

The puzzle is actually relatively simple. As is has only one assembly and that assembly can be found easily by finding some pieces that can go together only in one way.

So no need for a computer for this puzzle.

The pieces were made by the new Pelican workshop. The pieces are made out of 2 different woods so that you can actually see the 2 units they are made out of.”
