From the publisher: This game makes the cogwheels of your brain turn. Do you know who invented the bicycle, and how Blu-ray differs from DVD? If you don’t, find out with What everyone should know about the greatest inventions! On each turn players take one card and try to answer to the question on there! When getting the answer right you get 10 of the money the game uses! Then you have another change to go! Get it right again, you get 20, then 50, then 100 and then you have to give away your turn! You win the game when collecting amount of money agreed with other players at the beginning of the game! For example you win, when you get 250 that money!
