Voll auf die 18 is a funny, co-operative, and chaotic kangaroo card game with dice that also offers 100 good arguments against Nazis. Two to five players aged ten and up take on the roles of kangaroos, small artists or other members of the "anti-social network". Together they want to convince Nazis to make the world a little better. Each Nazi has an individual IQ. The players have to play cards with arguments (and numbers from 1 to 6), the sum of which corresponds exactly to the IQ of the respective Nazi. It is possible to "argue" alone or together. Some Nazis have a soft spot for certain things (for example, card suits) and bring further specifications into play. In addition, each character has its own rules of play that must be followed. The game is accompanied by an app that provides 18 increasingly difficult levels and also acts as a timer as new Nazis appear at regular intervals. The group loses if it has been surrounded by Nazis. If, on the other hand, all Nazis could be convinced within the time limit, the players win together.
