Incremental game

Progress with limited or no interaction In incremental games, players typically start off by performing simple actions – usually clicking a button or object – to earn a form of in-game currency. This currency can be spent on upgrades, items or abilities that enhance income generation, often automating the process and reducing the need for direct interaction. A common theme involves acquiring income-generating entities, which are frequently represented as buildings like factories or farms. These assets increase the rate of currency production, but higher tier entities usually have an exponentially higher cost. As a result, progressing between tiers tends to require a similar or increasing amount of time. This mechanism offers a low-pressure experience, characterized by the absence of failure states, steady progression, and frequent feedback. Those features make incremental games particularly well-suited for social or mobile play patterns, and often result in a very high player retention. Open-ended or closed gameplay loops Incremental games vary as to whether they have a victory condition: games like Cookie Clicker allow the players to play indefinitely, while games like Candy Box! or Universal Paperclips feature endings that can be reached after a certain amount of progress is made. Microtransaction and monetization Pioneered by AdVenture Capitalist, developers may sell premium boost such as instant currency infusion (usually a percentage of current rate of income) or sometimes wrapped as a "time-warp" (instantly gain x-hours of future income), permanent boost multiplier that persists after each prestiging, instant prestige (claiming prestige without starting over), protection against negative events, gacha system (random draws of a character or a permanent bonus), and event currencies. On the other side, they may also deliver advertisements for players to receive minor rewards, such as a short burst of cash, doubling offline earnings, a small amount of premium currency, brief powerful boost/medium-length small boost, extra prestige points upon prestiging, relief of a negative status, etc. ==History==

, a predecessor of Cookie Clicker'' According to Anthony Pecorella in his GDC summit talks, the creation of the idle game genre was attributed to Progress Quest (2002) by Eric Fredriksen, a parody of character stat progression and automated combat systems in MMORPGs. He argued that the gaming website Kongregate was an early hub for the genre, as some people preferred to use the integrated chat rather than actively play. The first idle game on Kongregate was aptly titled Kongregate Chat, where the game ran by itself while players conversed in the chat window. One of the first visual idle games ("rudimentary RPGs", according to Pecorella) was ''Ayumilove's HackerStory v1, a parody of bot grinding in MapleStory'', a popular Korean MMORPG at the time. The early pioneers of idle games also saw some games parodying the genre, such as Anti-Idle which has elements of both active and idle games. The game was extremely complicated, content-rich, and constantly updated. Another parody of idle games (and of capitalism), called AdVenture Capitalist, also saw success as a browser game and was subsequently made available on other platforms. It was one of the first games to implement monetization, as well as an offline earning system which tracks a player's progress while the game is not running, unlike previous browser-based idle games which only advanced when open in a browser window. and Candy Box!. Other idle games that have become classics include Sandcastle Builder which was based on the xkcd comic 1190: "Time", Shark Game, Crank, Mr.Mine, and Kittens Game. During the evolution of the genre, monetization (through ads or other venues), premium content, and other game mechanics were slowly being added in. ==Reception==

Nathan Grayson of Kotaku attributed the popularity of idle games to their ability to provide low-effort, unchallenging distractions that integrate easily into a person's daily routine, while adopting themes and aesthetics of more complex video games to appeal to a "core gamer" audience. He also observed that the genre supports a wide variety of mechanics and settings, including fantasy, sci-fi, and even erotica, offering enough perceived depth to maintain player engagement. IGN's Justin Davis describes the genre as designed for a perpetual sense of escalation: costly upgrades and items become available rapidly, only to be rendered trivial and replaced by more expensive options. This pacing creates a paradoxical experience where players feel both powerful and weak simultaneously, as they chase exponential growth. Julien "Orteil" Thiennot, creator of games such as Cookie Clicker, has described his own works as "non-games". In early 2014, Orteil released an early version of Idle Game Maker, a browser-based tool that enables the creation of customized idle games without programming knowledge. On the parodic nature of idle games, Pecorella commented that "this is sorta a genre that almost doesn't want to exist; it's a joke, but despite itself, keeps being really successful", and on popular idle-games in general, "a lot of these are just glorified spreadsheet with some really neat mechanics in it." == Influence ==

The idle games genre has influenced a range of other genres. Pecorella identified several genres that incorporate idle elements into their mechanics. Real-time social and strategy games such as Hay Day, Mafia Wars and Game of War let the player progress while they are away. Certain Chinese MMORPGs allow players to skip the early-game through "AFK mode" and to go straight to the end-game. Examples include Mythborne and Wartune. == Auto clicker ==

software An auto clicker is automation software or a macro designed to automate mouse clicks. Many incremental games employ active clicking as a means of gaining currency to complement passive progression. Players sometimes use auto clickers to automate this part and accelerate resource accumulation. Pecorella, in his 2016 GDC summit talk, argued that auto clickers are considered necessary by any "serious" idle game player and that their use reflects a design flaw rather than cheating. ==References==
