摘要

The toy has at least one plate (1) with a front side having a question (4) and several answers (5-7), a back side (3) and several guide openings (8-10), each with a different visible mark. A key with a bit fits in the front side of each guide opening and projects through the back plate, so that a mark on the bit lies next to the mark on the plate. A key has a bit, which can be fitted in the front side of each guide opening and projects through the back plate by a section, which is a different side for each opening. The key bit has a mark corresponding to the marks on the plate. When the key is inserted in an opening, the projecting section lies next to a mark, which is different for each opening that the key can be inserted into. The marks only match properly, if the key is inserted into the guide opening with the correct opening.
