What is the definition or description of: slot machine addiction?

Addictions are best: described by looking at eight elements. The first four define whether or not addiction exists: 1) It is mood altering, 2) It's compulsive, 3) It creates hardship or damage and 4) One doesn't stop despite the damage. The next four aspects tell us how the addiction manifests: 1) Tolerance, 2) Dependence, 3) Craving and 4) Whether its chronic or bingeing in presentation. All addictions qualify.
