Administrators can decide if they want users to be able to win just one prize during the promotion, or whether they want them to have the chance to win more. The default setting of the “Instant Win” feature is that users can only win one prize during the promotion. Thus, if the administrator enables multiple participations the participants will automatically have the number of participations defined by the administrator, but after winning a prize they will not be allowed to take part again.
However, the administrator can decide to change this behavior and allow users to win more than one prize during the promotion. This means that even if the user has already won a prize, he or she can try to win more.
To enable multiples prizes, you should access the Tools > Instant Win section of the promotion’s editor and ensure that you have disabled the “Participants can only win once”.
