This tournament is unique in that participants are only required to be Rossmoor residents; they are not required to be members of RTC. Also, Wild Card is played on the first Saturday of every month except November and December.

Like all the other tournaments, a notice is put in the Rossmoor News and a general e-mail is sent out to membership that sign up sheets will be posted at the Buckeye Complex kiosk 2 weeks before the day of Wild Card. Participation is limited to 12 men and 12 women. There is also space for people to sign up as alternates.
