BrainBox People at Work has cards with interesting facts on people at work and the jobs they do. Each round takes 10 seconds so all players are involved. A game lasts as long as you want it to, 10 minutes is the norm, but playing for 5 minutes is also great fun. BrainBox is educational and is perfect for families and groups of friends to play, wherever they are, on a level-playing field. The object of the game is to study a card for 10 seconds and then answer a question based on the roll of a dice. If the question is answered correctly, the card is kept, and the person with the most number of cards after 5 or 10 minutes is the winner.
