Passage: 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. In the game, players take the role of young graffiti artists who, upon being caught in the act of applying graffiti to  ("tagging") a metro railway site, run through the railroad tracks to escape from the inspector and his dog. As they run, they grab gold coins, power-ups and other items along the way while simultaneously dodging collisions with trains and other objects, and can also jump on top of the trains and surf with hoverboards to evade the capture until the character crashes on an obstacle, getting caught by the inspector or getting hit by a train. Special events, such as the Weekly Hunt, can result in in-game rewards and characters.
