I'd like to introduce to you a riddle game that is of my creation. It is called The Fortress and it is a thriller combined with extremely hard riddles. The idea is simple, you see a picture and you need to find a keyword (or keyphrase) that is an answer to the riddle. This answer is usually hidden, sometimes encrypted, sometimes clearly visible...

The game is available on iOS, Android and Windows Phone. iOS: itunes.apple.com/us/app/the-fortress/id41263700
