A 3x3x3 that allows swapping of centers with edges.
This puzzle was invented and patented in 1985 by Sergey Makarov. It was made as one-of-a-kind and never made it into massproduction. Back then it was named "Makarov's cube". In 2009 a new version shown here was designed by Oskar van Deventer without knowing the 1985-version. For more information see the "Hedgehog Cube".
It looks like a Rubik's Cube, but it has an unexpected twist. When a mid plane is turned by 45 degrees, other turns are possible. This way of turning mixes up the center and edge pieces.
In 2013 Witeden presented (in collaboration with Oskar) a mass produced version of this puzzle. Before there was only the version from shapeways.
This new version has an edge length of 65 mm.
