Subway Surfers - online puzzles

Subway Surfers is an endless runner mobile game co-developed by Kiloo and SYBO Games, private companies based in Denmark. It is available on Android, iOS, Kindle, and Windows Phone platforms and uses the Unity game engine. Players of the game take the role of teenage hooligans who, upon being caught in the act of applying graffiti to (tagging) a metro railway site, run down the tracks to escape from an 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, and can also jump on top of the trains to evade capture. Special events, such as the Weekly Hunt, can result in in-game rewards and characters.

Subway Surfers was released on 24 May 2012 with updates based on seasonal holidays. Since January 2013, updates have been based on a " World Tour" theme, which updates the setting of the game every three (or four, usually for seasonal holidays ) weeks.

In April 2018, Subway Surfers became the first game on the Google Play Store to cross the one billion downloads threshold.
