A $26.37 mobile riddle rally through Graz, starting at Schlossberg, with flexible play, seven top landmarks, and fun puzzles in English.

“Interesting idea, poor interface. The system apparently did not interact properly with an iPhone on an American account. The tips button simply didn’t work at all. Unless the question used direct material from the historic site itself, one would need an Austrian education to get Austrian historical trivia. My guess is that the hints make it possible for foreigners to play, but we simply don’t know because it wasn’t functional. We finally gave up in frustration.”
