When I am playing Jeopardy, I put the class into small teams and they must elect someone from each team to buzz in for the group. This person can't answer a question (they only buzz in), the rest of his/her group can must answer the question if they are first to buzz in. I use a devise called an "Eggspert" which tells me who was first.
For family fued, each person represents a small group who must either answer or give advice to the panle member. Hope this helps.
