This game consists of keeping one's pins standing while knocking down the opponent's pins. Players get 1 point for each pin still standing at the end of each round. The first player to reach 15 wins.
The trick is that players' pins are knocked down by a spinning top (the Tornado Top) released onto the playing field that can stray into either one or the other player's territory, knocking down either one's pins. Small levers can be set up at certain points, pointing in certain directions, to try to deflect the top to go a different way, but ultimately it's all down to dumb luck as to where the top will go.
What this game lacked in strategy, it made up for in fun, but for whatever reason it was available for only a short time.
