Does an orange float in water? Can you be allergic to a hairless cat? Does Transylvania really exist? Is C the letter between V and N on a keyboard? The trivia game ...I should have known that! Yes or No contains more than four hundred "yes or no" questions about things that you should know. Sound like a piece of cake? You'll be surprised how baffling even the easiest questions can be when you don't have Google at your fingertips! Instead of receiving positive points for correct answers, you are burdened with negative points for wrong answers — and the number of points you received depends on how easy the question is. The player with the fewest negative points wins.
