Promotion Type Mayor Specials: unlocked only by the Mayor of your venue. Who's the Mayor? It's your single most loyal customer! Check-in Specials: unlocked when a user checks in to your venue a certain number of times. Frequency-based Specials: are unlocked every X check-ins. Wildcard Specials: always unlocked, but have someone to verify before giving promotions. This is very important and should be a huge incentive to attract users to your business. Remember, there can only be one mayor of your business, so give them something to fight over!
