What kind of game this is
There is a large cookie on the page. You click it and you get a cookie. Cookies buy a cursor that clicks for you, then a grandma who bakes for you, and within a few minutes the number climbs without your help. Orteil wrote the first version in a single evening in August 2013 and had roughly fifty thousand people clicking within hours.
The joke was that this is not a game and that you will play it anyway. The reason it is still funny is that Orteil kept answering it. Cookie Clicker is still maintained in 2026, carries more than six hundred upgrades and over five hundred achievements, and sells on Steam. Every time the parody should have run out of material, another floor appeared underneath.
The first hour
Buildings are the economy. Each produces cookies per second on its own, and each purchase of a given type costs about fifteen percent more than the last, which is the price curve most of the genre inherited from this game. The list starts at cursors and grandmas, works through farms, mines, factories, banks and temples, and ends up around a Javascript Console and an Idleverse.
Upgrades sit beside the buildings and matter more, since most double the output of one building type outright. Golden cookies appear at the screen edge at random and pay a large temporary bonus if you catch one, which is the only argument for keeping the tab visible rather than minimised.
Grandmas, and where the joke turns
Grandmas are the second thing you buy and the game's actual protagonist. Upgrade them far enough and they start turning up inside the other buildings, in the mines and the temples and the portals, each with a line of flavour text a little worse than the last. Then an upgrade called One Mind appears, and buying it begins the Grandmapocalypse.
The background changes and the cookie changes. Some golden cookies become wrath cookies, which can help or hurt. Wrinklers attach themselves to the big cookie and eat your production, and the right response is to leave them there and pop them later, because they hand back more than they took. That is a real decision, and it is also the point where a game about baked goods turns into cosmic horror without changing its tone. You can undo it. Almost nobody does.
Ascension and heavenly chips
The prestige layer is a Legacy button tucked behind the Info menu. Ascending wipes the run and converts your lifetime cookies baked into heavenly chips and prestige levels at a one to one ratio, each level adding a percentage to production permanently. Chips buy heavenly upgrades that survive every future reset.
Ascending early gives you almost nothing, because the conversion is punishingly slow at the bottom of the curve. After the first one, a run stops being something you play and becomes something you set up and harvest.
Sugar lumps and the four minigames
Sugar lumps unlock after one billion cookies baked. One grows at a time and takes around a day of real time to mature, which is the game's only hard clock and the most effective reason people come back tomorrow. Lumps level individual buildings, and the first lump spent on four of them opens a minigame each: the Garden on farms, the Stock Market on banks, the Pantheon on temples, and the Grimoire on wizard towers.
None of these are decoration. The Grimoire casts spells that manufacture golden cookie effects on demand, the Pantheon slots spirits into tiered sockets for passive bonuses, and the Garden is a plant breeding puzzle with a hidden seed tree that takes weeks to fill in. The Stock Market is the shallowest and the one to leave until last.
Controls, and the phone question
You click a cookie and you click buttons. The only control worth learning is the buy quantity selector above the building list, which switches between buying one at a time and buying in bulk. The browser version is cramped on a phone, since the layout is three columns of small text and golden cookies are hard to hit. The official Android app, released in October 2020, is the better answer there. Saves live in the browser and the options menu exports one as a text string, so clear your site data and the run is gone.
How long it takes
Cookie Clicker does not end. The hundred hours in this page's data is roughly what people report for unlocking most of the building list, running several ascensions and seeing the minigames working. That is a fair definition of having played it, and it is not completion. There is an achievement for a save file over a year old.
Getting further
Buy upgrades before buildings, nearly always. A doubling beats one more grandma.
Do not start the Grandmapocalypse until you have the upgrades that make wrinklers profitable. Before that they are a tax.
Spend your first sugar lumps on wizard towers and temples.
Who made it, and where to play
Cookie Clicker is by Orteil, the French developer Julien Thiennot, working as DashNet with Opti, who runs the hosting and the community and is credited as co-developer on the Steam release. The soundtrack for that release was composed by C418.
The free browser version at orteil.dashnet.org/cookieclicker is the real game. It is the version Orteil updates, and nothing is held back from it. The Steam release came out on 1 September 2021, published by Playsaurus at around five US dollars, and adds cloud saves, Steam achievements, the C418 soundtrack and Workshop mods. Those are conveniences. Buy it to pay the developers, not because you expect a different game.
No licence permits anyone else to host the game, and the code itself asks people not to re-host it or profit from it, which is why this page sends you to Orteil's own site rather than running a copy.
