I Know Better: Mini Inventions and Discoveries plays a game of Quidditch and an expansion of the manual all in one! Which American is credited in history with the invention of the assembly line? Who was Ferdinand von Zeppelin? What do the symbols and numbers we find on light bulbs mean? Challenge your friends with science and take a look at their friendship with a special mini-game from the "I Know Better" series! "I Know Better: Inventions and Discoveries" consists of 60 questions that test your knowledge of the key figures and achievements in the world of science. Answer questions only from this category, but also use the set as an addition to the strategy game "I Know." In the box, you will find a category card that you can add to the main pool or replace one of them with. What does this mean? The category card must be available to all players. When it is a player's turn, they read the question on the card aloud. If an opponent knows the answer to a read question, they take a category card and shout "I know better!" They must do this before answering. Then, the player whose turn it is answers the question and mysteriously checks if the answer is correct. If the answer is wrong, the category player responds. The game continues until one of the players receives category 5 discs.
