The tandem boards promote basic writing and reading skills. The tandem boards encourage parallel and mirrored hand movements and thus train fine motor skills and hand-eye coordination that are important for writing and drawing. At the same time, concentration and close observation are practiced, because especially with more complex patterns, the hands reach a more consistent target faster if the "path" has already been understood in advance.

How are you? The game consists of a total of five boards, each with two mirror-symmetrical figures milled into them. The buttons have a pin on the bottom that guides them into a groove. In addition, they have a depression (finger cup) at the top, so that they can be moved with one finger or with several fingers at the same time. Because the buttons are separate, it is possible to customize larger or more convenient buttons yourself.

The different boards have different difficulty levels. It starts with the spiral and continues until the meander. First, one draws the figure in question with one hand, from the outside to the inside and back again. Then it is the other hand's turn. Once the shapes are somewhat familiar, both hands can work at the same time.
