Perhaps another way to justify the distinction between skill games and games of chance is their relative popularity. For example, slot machines do not require training and anyone can play and potentially win thousands or even millions. As a result, given such broad appeal and “accessibility,” the potential audience to be invited to play and to invest its discretionary income is much larger. On the other hand, given the level of skill required, skill-based games do not normally enjoy such mass participation. This distinction normally concerns those in the business of providing traditional forms of gambling, such as casino-style gambling or sports wagering, because of the paternalistic nature of gambling laws, which is normally a bar to these forms of gambling.63 What is generally overlooked is that there is an element of chance even in skill-based games, and vise versa. For example, only a few hundred chess players have a realistic chance of winning major chess tournaments. Judge Williams perceptively commented on the skill necessary to win pool tournaments: “[b]illiards and pool are not games of chance. If any one [sic] thinks they are, let him go and play them for a stake, and he will promptly discover his error.”64
