Cookie Clicker is a browser game built around clicking an oversized cookie in the middle of the screen to bake virtual cookies1. Players spend those cookies on upgrades like cursors, grandmas, farms, mines, and factories, each one automating production so the counter keeps climbing without any more clicks. Text along the top of the page cycles through milestone lines as the total grows, adding a running commentary to the operation1.

Two versions of Cookie Clicker exist: the original experimental prototype and a later polished actual game, both hosted on Orteil's Dashnet domain1. An early Urban Dictionary entry called it "a fucking addictive game" that gives players "the illusion that you are making cookies, but you are really not," catching the mix of pointlessness and compulsion players kept describing5.

Load the game at Orteil's Dashnet page, click the giant cookie to bake cookies, and spend those cookies on cursors, grandmas, farms, and later factories, mines, and more exotic buildings that bake for you automatically1. The typical loop is: click for a while, buy the cheapest upgrade, watch the per-second rate rise, and keep reinvesting so the counter grows on its own even while you tab away.
