The new voluntary limits for machines do not work because problem gamblers will not choose to restrict themselves

In the 18 months after the Code came into play, some 85% of players walked away when they reached their limit, or stopped putting any new cash into the machine.

All customers have to make an active yes/no choice on whether or not they wish to set a limit. The number of people setting voluntary limits rose dramatically, with 90% of those setting a limit stopping their gambling session before that limit is reached.
