The Speed Quiz
There are also several versions of the Speed Quiz but in this post is the version from the first episode described.
You need two team again. One person of the first team will stand a few meters (15 m~20 m) away from the other team members.
This person has small carts with terms and definitions and tries to explain them (without naming the term) to his team members who have to guess it.
Between the person with the carts and the other persons of his team stands the members of the other team and shouts, sings, claps with their hands (everything that is loud enough for the members of the other team to not understand their explainer).
After the time (30 sec ~1 min) is over the teams change places.
The team that guessed the most terms right will win the game.
