Cookie Clicker's game interface
|Release||10 August 2013|
Julien "Orteil" Thiennot created the game Cookie Clicker in August 2013. Featuring similar mechanics and objectives to the previous games, Cow Clicker, it also included new gameplay features. The game was first posted on 4chan's /v/ board on 8 August 2013  and later spread through social media sites. Orteil later wrote that traffic had peaked at 1.5 million hits in one day during August 2013, and as of January 2014 Cookie Clicker was still getting a steady 225,000 hits per day.
This genre involves games that orient the player with a trivial task, such as clicking a cookie; and as the game progresses, the player is gradually rewarded certain upgrades for completing said task. In all, these games require very little involvement from the player, and in most cases they play themselves; hence the use of the word "idle". This process of rewarding a simple action, or positive reinforcement, is what causes idle games to be commonly known as “super addictive”. The design is such that, with each reward, the player feels a sense of pride as if they have accomplished something important, thus creating the urge to continue to play.
However, due to their mockingly simple mechanics, idle games are also considered by many of being relatively simple or, as stated in the IGN article, "super dumb". Games such as Cookie Clicker have used this blend of simplicity and complexity to create a new genre that some may not even consider as actual games. Orteil himself described his works as "non-games". However, while idle games, or "non-games", do not contain many aspects typically associated with games, they have a large presence on the Internet, in comparison to true games. In early 2014, Orteil released an early version of Idle Game Maker, a tool allowing customized idle games to be made without coding knowledge.
In late 2014, Orteil collaborated with Artix Entertainment to release an idle game for mobile devices called AdventureQuest Dragons.
Boing Boing reviewed Cookie Clicker as a "highly-addictive browser game". Polygon has described the game as "intriguing", and its fan base as "obsessive". About.com states that it is ultimately a "Skinner box". Destructoid emphasizes that it is "centered around the pursuit and accumulation of vast wealth", providing players with "the illusion of progress, without any substantial advancement actually being made."
