The square gameboard resting inside the box lid represents a spider's web. The little wooden tops that players spin are the spiders. The numbered holes on the gameboard represent flies the spiders want to capture and eat.from the box lid:Each player, in turn, takes the two wooden spinners and spins them one at a time in the center of the 'web'. For each top which rests in a numbered compartment with the sphere end down, the player scores the amount printed under it. If the spinner rests in a compartment with the peg end down, the player scores double. A game consists of 100 points, and the first player who scores that amount is the winner. - BoardGameGeek
