Tipboards are often a lot like pull-tabs, except that certain winners get to sign up on a posted board or sheet, essentially giving them an entry in a grand prize drawing (much like a raffle). You will often see tipboards played in bars during special events or seasons, with the grand prize being a certain piece of merchandise (like a rifle or shotgun during hunting season).
