The "fudged" cousin of the tuttminx which allows more movements.
Futtminx stands for "fudged Tuttminx".
The hexagonal faces of the original Tuttminx can only be turned by multiples of 120 degrees. If one tries to makes 60-degrees turns with the Tuttminx, then adjacent turns are blocked.
The Tuttminx 1 (which was sold out in 2014) had the ability to turn the hexagons still allowing next turns but that did not last forever and after a few turns every side was stuck. Possibly it was possible because of the curved cuts. The Tuttminx 2 had cuts done straight, as a result "illegal turns" were impossible to be executed. However, the Futtminx never has these lockups ever occur. This was acomplished with the loose hanging edges.
The shape is identical to the original Tuttminx, a truncated icosahedron which is an archimedean solid.
All corners and edges are manipulated to allow 60-degrees turn of the hexagons. The Tuttminx has two different types of edges while the Futtminx has only one type of edge. The puzzle has a lot of gaps between the pieces. Also, the pieces shift a bit during a turn to make all turns possible.
