NumDuel is a quiz game in which there is no right or wrong. You don’t choose between different answer options; rather, you guess the answer to the question and get points depending how close you are to the correct answer. If this wouldn’t be fun enough, you play the game against your friends or random opponents, whoever you prefer. A very simple example question is: “What percentage is equivalent to three quarters?” If you guess 25 and the correct answer is 75, your score is 33. The game consists of five rounds, each with three questions per player, and you can choose questions from over 10 different categories, ranging from science to entertainment. The goal is to have a higher score than your opponent.
