How about a game of Jeopardy to lighten up the mood after a sprint? Jeopardy is a TV gameshow debuted in 1964. The show features a quiz competition in which contestants are presented with clues in the form of answers, and must phrase their responses in the form of questions.
An online version of Jeopardy is available, you can choose the readily available question sets or create your own custom questions. Custom quizzes are limited to 5 category x 5 questions for free, payment and registration is required when you go beyond.
At least 3 members are needed to play the game. You need at least 15 minutes. I made a custom game board and asked personal details about each participant for the other participants to guess.
Don’t forget to have fun!
