There are two spinners. One is spun to determine a result up to 20, the second one to determine how many number chips have to be used to get to that number. For instance, if the spinners show 16 and 3, you could use 7+5+4. The first player to place the correct chips (every player has different ones) on the table scores a point. The winner is the player with most points at the end. - BoardGameGeek
