Cookie Clicker

A casual incremental game in the "clicker" genre, developed by independent creator Orteil. The player starts with a simple mechanic—clicking on a giant cookie to earn cookies, which can then be spent on automated upgrades such as bakeries, farms, factories, and even scientific research to increase production speed. As progress is made, additional mechanics unlock, including mini-games, special upgrades, random events, and even dark rituals that further accelerate production. Despite its simple concept, the game features a deep progression system, hidden secrets, and various strategies for optimal growth. Cookie Clicker became a cult classic in the genre, popularizing clicker mechanics and inspiring many successors. The game is available in-browser, on Windows, macOS, Android, and iOS.
