Sei stark. Sag Nein! is aimed at teaching kids how to react to dangerous situations with strangers. It consists of cards in three colors: Red cards show a picture and ask a multiple choice question about how to behave in the corresponding situation. The player should give the right answer and also explain why she thinks it's right. Green cards demand physical tasks of the players and are aimed at strengthening the physical self-conscience. Blue cards train observing skills: The players see a picture and are asked questions about it. Players take turns drawing a card; a moderator poses the questions. Each correct answer or fulfilled task is rewarded by a point. After a pre-determined time, the player with most points wins.
