The Great app was developed for the 195th anniversary of Leo Tolstoy as part of the Great art project, which popularizes the names of famous figures of Russian culture among young people. In the space of the foyer of the Novosibirsk Academic Youth Theater "Globus" 12 thematic locations have been created related to the biography and work of Tolstoy. In each location, the participants will meet with the character of one of the major works of Leo Tolstoy. The whole journey is an intellectual game-quest, during which participants will hear non-textbook facts of the writer's life, voiced by the voices of theater artists. Participants must find answers to questions using the application's hints. As a result of passing all the points of the quest, subject to the correct answer to all tasks, the participant can count on a prize from the theater.
