The players are asked ten questions. For every question, they have to choose among four answers.
If the player’s answer is incorrect, he is penalized with three negative points. If the player’s answer is correct and he responded faster than the opponent, he is rewarded with six points. In case of answering correctly but not doing it as fast as opponent, the player does not win or lose points.
If the player does not know the answer, clicking on the button Skip turn, he waits for the opponent to answer and moves on to the next question. By clicking on the skip button, players do not lose points.
