This 6 block burr puzzle was acquired from the Yallingup Maze as in my previous post on The Cube. Again it is made by Mr Puzzle Australia of cedar stained radiata wood. Externally, this puzzle seems to be similar to the Sly Burr on the Mr Puzzle Australia site and the wood there used by the Sly Burr is different. This is where any similarity ends; Allard has commented "the Sly Burr really lives up to its name" (Allard, thanks!). The package description states that this puzzle was sold as the The Small Devil's Hoof in its earlier incarnations. It is a fairly large burr of around 90mm square. The puzzle was actually available in either sharp edged or bevel edged and I chose the latter. Again, overall quality is very good here.
The object of the puzzle is to assemble the 6 blocks (all differently cut) into one interlocking burr. None of the 6 blocks are identical while 1 is a solid piece which locks the puzzle together.
Allard has also written about the Just Six so you may want to check out his comments on it.
