Sheet on hot slots tells past, not future
Darla's husband was playing slots yesterday and he complained about the fact that there are no sheets showing what slots were paying off. Darla and Ned have been friends since college. Ned agrees with Darra that sheets don't help. The sheets tell you what games have paid more than usual over a short period and don’t tell anything about their future performances. The information is based on the machine's performance. It's based only on their performance during that period. There is no tendency for a machine to stay hot or cold. Hot and cold times grow out of normal probability.
