Cookie Clicker began as a browser idle game created by French developer Julien Thiennot, known as Orteil, and released in 2013. Players click a giant cookie to earn cookies, then spend them on cursors, grandmas and factories that produce cookies automatically. Its simple loop, absurd upgrades and ever-growing numbers made it a cult hit and a lasting reference point for idle games. Online, clips of its clicking and chimes now circulate as shorthand for obsession, grinding and pointless but addictive progress.
