(from the rules) In the 1920's a new concept of snow travel was invented in Canada! The Snowmobile! Since that time the snowmobile has developed from a large, bulky commercial type machine to the sleek personal machine it is today. The snowmobile is a recreational vehicle that can be enjoyed by the whole family, but is also a vehicle for those who are competitive and like to participate in that fastest growing of winter sports, snowmobile racing. There are three basic types of snowmobile racing: oval track; drag; and cross country. Of the three, cross country demands the most from both rider and machine. Burton Cole developed and designed the Scorpion Championship Snowmobile Derby game to give you all the excitement and challenge that normally occurs in an actual cross country race.
