Dogic
The Dogic is a mechanical, three-dimensional puzzle and is comparable to the Rubik's Cube or the Megaminx .
history
The Dogic was registered for a patent by Zoltan and Robert Vecsei in Hungary on October 20, 1993. The patent (HU214709) was granted on July 28, 1998. Originally the Dogic was sold by VECSO in two versions, under the name "Dogic" with 12 colors and "Dogic 2" with 20 colors.
In 2004 Uwe Mèffert acquired the rights to produce the Dogic. In addition to the two known color variants (Dogic I and VI), he produced more with 10 (Dogic II), five (Dogic III) and two (Dogic IV + V) colors.
The Dogic is now no longer in production and can only be purchased second-hand. This led to high demand and high prices at auctions of up to several hundred euros.
functionality
The Dogic is an icosahedron with twenty side faces in the form of regular triangles. Each of the side surfaces is in turn divided into four smaller triangles, with the central triangle being divided into three triangles. This central triangle is the mechanical equivalent of a corner of a Megaminx .
The mechanical puzzle can be manipulated in two ways. On the one hand, the tips of the Dogic - consisting of five small triangles - can be rotated like five complete sides at the same time.
The 12-color variant is the most difficult to solve.
