摘要

The logic play has several cubes and a playing field with square fields, on which in the points of corner of the fields pins are attached by heads. The pins with heads are in recesses at the sides of the cubes such that pulling the cubes out is not possible. On the playing field burls are attached, which prevent a shifting of the cubes with appropriate recesses in the cubes into a neighboring free field.
