The first player to collect five cards, one from each category, or seven cards in total, is the winner of the game. Arrange all the question cards in one pile, face up, and the action cards in a second pile, face down. A free space must be left for cards that have already participated in the game. Each player in turn draws a card from the pack, reads the question and tries to guess which is the correct answer out of the four options if you answered the question correctly • Read aloud the conclusion of the experiment written on the back of the card. • If the card includes a bonus question, try to answer the question. A correct answer to the bonus question entitles the player to an action card. If you made a mistake in guessing the result of the experiment, read the correct answer and the conclusion of the experiment which are written on the back of the card and give the card to the player with the lowest number of cards. Now it's the next player's turn
