Show your friends, family and other players how good you know our world in numbers. 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!

Love this game!

I’ve been playing this game almost from the beginning. It’s educational, fun and challenging all at the same time. Some questions are extremely hard, but even if you don’t know the answer you still have an opportunity to score points. Love how a round only takes a few minutes and you have up to 3 days to play. Challenge your fiends to play or give a random player a try, either way you’ll be hooked!
