Eye Know is a visual trivia betting game. At the start of the game, a number of cards are laid out. On a turn, you choose one of the cards and identify the image on it. (This isn't the hard part, but rather a precursor of what's to come.) If you correctly identify the image, you can then choose to answer a trivia question relating to the object named on the card. Questions come in three varieties — true/false, multiple choice, and open ended — and the payouts are higher for the tougher questions. Eye Know Mitbringspiel includes one hundred picture cards that can also be used as an expansion for the Eye Know board game.
