It depends on the promotion or what is going on and how many total number of cards are in play. I don't really have the time to re check the total amount of cards. It has been almost a year and a half since I messed with Bingo so forgive me if I have this number wrong. I have been on plays where I have used my points and it has cost me 25 cents or 50 cents to validate playing maximum cards. What do I know? Obviously nothing if the Wiz is telling everyone never to validate.
