Crokinole has been around since olden times. If you've ever played shuffleboard (and who doesn't like heaving discs on the deck of a cruise ship), you probably already have a good grasp of how Crokinole works. Heck, if you've ever played marbles, you will get it. You shoot discs at the center of a circular board, trying to get your discs to stop near the center where zones are worth more points (like a dartboard). The very center is worth 20 points, and then it goes down as you go out further: 15, 10, 5, and 0 points.
