In 2013, developer Orteil published Cookie Clicker as a joke about idle games. It became one of the most-played browser games in history. The mechanics are deliberately absurd: click a giant cookie, earn cookies, spend them on cursors, grandmas, farms, factories, banks, temples, wizard towers, and eventually time machines and portals. The numbers grow from hundreds to millions to septillions without pausing to explain itself. The game has been continuously updated for over a decade and still draws millions of players.
After baking enough cookies, you can "ascend" — sacrificing all your cookies and buildings to earn Prestige levels and Heavenly Chips that provide permanent multipliers. The first ascension feels like losing everything; by the third, you understand that each reset is building toward a production rate that would have taken years without it. The deep game is min-maxing your prestige timing and unlocking the right Heavenly Upgrades. The game's wiki is extensive. You'll need it.
Orteil's Cookie Clicker has been available on its official site since 2013, but playing it on Soccer Bros removes every piece of friction between you and the cookie: no popups, no account prompts, no competing banners. The game runs identically to the original and saves your baking session to browser localStorage automatically — close the tab and come back days later to find your grandmas have been baking the whole time. For an idle game where the whole point is returning periodically to enormous numbers, that seamless save behavior is exactly what you need.
