Subway Surfers is an "endless running" mobile game. It was co-developed by Kiloo, a private company based in Denmark and SYBO Games. It is available on Android, iOS, Kindle, and Windows Phone platforms. Players of the game take the role of youthful hooligans who, upon being caught in the act of applying graffiti to (tagging) a metro railway site, run down the tracks
to escape the Inspector and his dog. As the hooligans run, they grab
gold coins out of the air while simultaneously dodging collisions with
railway cars and other objects. Special objects, such as the Weekly
Hunt, can result an award in the game.Subway Surfers was released in May 2012 with updates based on seasonal holidays. Since January 2013, updates have been based on a "World Tour" which places the game in a new city every month. As of 12 February 2015, 21 cities have been featured in the game. The current city is Hawaii.
