We did make a free beer mobile application in 1999, when cell phones had been still big, called Happy Hopper. The idea of the service was: You send an SMS to our server, we send you an SMS back to a pub in town, together with a riddle to solve in that pub. Solve that riddle and you get a free beer and the address of the next pub. The SMS also served as a ticket for the bus.

Success of this service was based on working with our local brewery, and local radio station to advertise it, and of course public transport. Happy Hopper did run two times during the Freimarkt and Osterwiese fair. So you also need a date, where you can expect lots of people who enjoy to get drunk.

That sounds great haha. I live in Ireland so it's bound to be popular!

As a fellow Irishman I agree, it could work very well with tourists too, a drinking tour of Dublin where you have to solve the leprechaun's riddles markets itself!

What a great idea for Vatertag in my corner of Germany. Some of the folks here still celebrate it as a day for drinking with other fathers during a really long walk in the forest.
