Game of skill for training and improving spatial thinking

摘要

This game of skill is intended for training and improving spatial thinking and increasing the power of spatial perception. This is achieved by means of variously shaped playing pieces which are formed by free spatial combination of a particular number of identical sub-units, without repetition. A subsidiary condition here is that at least two sub-units in each case contact each other at a common surface and are fixedly connected to each other at that surface, with a single exception, one playing piece which consists of the particular number of existing loose sub-units. A geometrical figure, for example a cube, is then to be produced from these playing pieces. There are countless possibilities, but only a few which result in success.
