Games become more popular than cinema, it is a trend worldwide. The annual turnover in gaming industry already exceeded 15 billion dollars, and it still grows every year. The author proposed several types of logical gaming devices, including the type combinable with a ball-pen. As preliminarily estimated, such gaming devices might be used with 10—25% of ball-pens produced worldwide, and they might be demanded for both on national and international markets.
