Cookie Run (Hangul: 쿠키런; RR: Kukileon, stylized in CamelCase) is a series of online mobile endless running games developed by Devsisters. Inspired by the classic folk tale The Gingerbread Man, the series is set in a world of conscious gingerbread cookies that were brought to life in an oven by a witch and have since escaped her evil clutches. Each game has a mechanic of the cookies running to earn points and items, overcome obstacles, and fight or escape enemies.  The series is available on iOS and Android devices.

Cookie Run at the moment includes six modes, with other modes that will come and go for events. Each game is based on the "freemium" model, which offers the basic game for free while encouraging users to pay in smaller doses for virtual in-game items or abilities.
