Fisher Cube
The Fisher Cube is a rotating puzzle modeled after the classic Rubik's Cube , which was developed by puzzle designer Tony Fisher in the mid- 1980s and named after him. As one of the first variants of the 3 × 3 magic cube, the Fisher Cube is considered to be the forefather of all 3 × 3 cube shape modifications. The goal of the puzzle is, similar to the normal Rubik's Cube, to bring all parts of the puzzle to their original positions by skillfully rotating them. Once the puzzle has returned to its cube shape and only one color is visible on each surface, the Fisher Cube is solved.
Structure and appearance
When dissolved, the Fisher Cube has the shape of a cube, and each face of the cube has its own color; However, if you twist the cube, the parts take up a different rotational position and the cube shape is destroyed. Instead, individual parts often protrude slightly from the surface of the cube, so that it takes on an indefinable mixed form. Of course, the single-colored sides are also destroyed when mixing and the cube looks colorful. If you pay attention to the individual parts, you will notice that the cube consists of 3 × 3 × 3 parts, which are arranged like the parts of the normal Rubik's cube. Nevertheless, parts with the same function in the Fisher Cube, for example edge parts, have different shapes. This results from the fact that the axis of rotation is like that of a normal Rubik's cube, but rotated by 45 degrees.
Solution strategy
The solution method can easily be derived from that of a classic Rubik's Cube, since the Fisher Cube has the same structure; however, some special cases must be taken into account that do not occur with the classic dice. For example, with the Fisher Cube, attention must be paid to the orientation of the central stones, while this is usually irrelevant. Therefore, the cube is a little more difficult to solve than a 3 × 3 Rubik's Cube.
Records
No official World Cube Association championships are held for the Fisher Cube. That's why there are no official records. The unofficial world record is 14.05 seconds and was set by Sebastian Häfner.
