In the field of intellectual games, there is a huge shortage of teaching aids for working with children 13-16 years old. To teach teenagers who want to participate in similar games ("What? Ubi? When?," "Brain Ring," "Own Game," etc.), spend leisure time with an intense intellectual focus, you need to teach them the basics of game thinking and thus push them, on the one hand, to the development of individuality, and on the other - to interaction in a team, where sometimes it is necessary to subordinate your "I" to common interests for the benefit of the cause.
