In the children's game 1x1 Drachen, children aged 7 - 10 cleverly multiply by numbers in the small multiplication table in order to be the first to fill their own bingo board and win. Rolling the dragon eggs brings excitement and variety. Beginners can have just as much fun with this game as professionals, because the rows can be chosen freely by the children and the level of difficulty can be increased. In a playful way, it promotes a secure mastery of the basics.
