As you accumulate cookies, you can purchase upgrades like grandmas, farms, factories, and even portals and time machines to produce cookies automatically. The more you play, the faster your cookie empire grows, unlocking achievements, special upgrades, and even heavenly rewards through ascensions. With endless progression, quirky humor, and a surprising amount of strategy, Cookie Clicker turns mindless clicking into a surprisingly fun and satisfying experience.
