In the state of West Virginia, Video Lottery is the legal use of player interactive gaming machines similar to those commonly known as "slot" machines in the casino industry. As of 1994, video lottery was approved, with restraints set forth by law, at West Virginia’s four thoroughbred and greyhound racetracks. The issue had to be approved by voters in the counties in which each track is located.
In 2001, the West Virginia Legislature passed a bill allowing for a limited number of video lottery machines in adult environments. It is referred to as the "Limited Video Lottery Act." The measure outlawed pre-existing "gray" or "poker" machines and restricted the number of Limited Video Lottery terminals to no more than 9,000. The environments in which they are permitted are classified as adult-only based on the fact that they possess a Class A, Alcohol Beverage Control Administration (ABCA) license and meet various other legal requirements.
