So, you’ve been clicking. Or, more likely, you’ve let a swarm of Grandmas and Fractal Engines do the clicking for you for the last three weeks. You’re looking at that counter at the top of the screen and wondering: when do I hit the end? When do I get infinity cookies on Cookie Clicker?
It’s a trick question.
Orteuil, the developer (real name Julien Thiennot), built a game about exponential growth, but even the most chaotic idle games have to play by the rules of computer science. You can’t actually have "infinity" in the way a mathematician thinks about it. Computers are finite boxes of silicon and wires. They have limits. Specifically, they have the double-precision floating-point format limit.
Basically, the game breaks before you hit forever.
The Technical Ceiling: 1.79e308
Most players think they can just keep ascending, stacking prestige levels until the numbers lose all meaning. They do lose meaning, but they also hit a hard wall. Because Cookie Clicker is a JavaScript game, it relies on how JavaScript handles numbers. It uses the IEEE 754 standard.
The largest number it can handle is $1.7976931348623157 \times 10^{308}$.
If you try to go one step further? The game just gives up. It displays "Infinity."

This isn't a reward. It’s a crash state. Once your save file registers infinity cookies on Cookie Clicker, the math starts to melt. Adding one cookie to infinity is still infinity. Subtracting a billion cookies for an upgrade? Still infinity. The game stops being a game because the "game" part—the resource management—is gone.
I've seen people try to force this with "Cheated cookies taste awful" (the shadow achievement you get for using the console). They'll type Game.cookies = Infinity; into the inspector. Sure, the UI changes. But you’ve essentially bricked your save. You can't buy anything that calculates its price based on your current CPS because the math returns NaN (Not a Number).
Why You See "Infinity" Early
Sometimes you aren’t even at the 308-digit mark, but the game starts acting weird. This usually happens with mods or specific Golden Cookie combos. If you stack a Frenzy, a Building Special, and a Click Frenzy during a Godzamok sacrifice, your cookies per second can spike so high that the engine stutters.
It’s about the buffer.
The game calculates your cookies at a rate of 30 frames per second. If your CPS is high enough that the "cookies earned per frame" exceeds what the variable can hold, you've hit a functional infinity. You’re essentially playing in the overflow zone.
Most veteran players on the Discord or the DashNet forums will tell you that the real "infinity" isn't the number. It's the "Endless Cycle" achievement. It’s the grind for 1,000 ascensions. That is a psychological infinity. It feels like it takes forever. It probably does. Honestly, by the time you're hitting the vigintillion range, the numbers are so big that they might as well be infinity for the human brain.

The Myth of the Infinity Upgrade
There is no secret "Infinity Upgrade." You might see screenshots floating around Reddit or 4chan showing a shimmering infinity symbol in the store. Those are fake. Or, they're part of a mod like Cookie Clicker Plus or CCSE.
In the vanilla game, the highest-tier upgrades are currently tied to the highest-tier buildings like You and Idleverses. These buildings don't lead to an infinite loop; they just provide massive multipliers.
If you’re hunting for infinity cookies on Cookie Clicker because you want to "beat" the game, you’re looking at it the wrong way. The game is designed to be a satire of capitalism. It’s about the absurdity of growth for the sake of growth. When you hit the "Infinity" display, the satire is over. You've won, but you've also broken the universe.
Glitches, Mods, and the Console
Let's be real: most people asking about this are looking for the Game.Earn() command.
- Open the console (F12 or Ctrl+Shift+J).
- Type
Game.cookies = Number.MAX_VALUE;. - Watch the counter hit the limit.
But here is the thing. Doing this skips the entire dopamine loop. The reason Cookie Clicker works—the reason we all still have a tab open ten years after it launched—is the incremental crawl. Seeing the number go from "million" to "billion" feels better than just forcing the variable to its limit.
There are also "overflow" glitches. In older versions of the game, certain garden plant combinations (like Queenbeets) could be harvested during a massive buff to grant more cookies than the game could technically track if the CPS was boosted by a negative interest rate or a broken "Cursed Finger" effect.

Most of these have been patched. Orteuil is pretty good at keeping the math stable, even when it’s reaching the scale of the total atoms in the multiverse.
Practical Steps for High-Level Play
If you actually want to get as close to the limit as possible without cheating, you need to master the Garden and the Grimoire. Don't just sit there.
- Stack Golden Cookies: Use "Force Hand of Fate" from the Wizard Towers right when a natural Frenzy is active.
- The Garden Sacrifice: It's painful, but sacrificing your full seed catalog for those 10 sugar lumps is the only way to level up your buildings to the point where "infinity" looks even remotely possible.
- Dragon Guts: Switch your Dragon Krumblor to "Radiant Appetite" for the 2x multiplier. It’s non-negotiable.
Once you reach the point where the game says "Infinity," you've effectively reached the heat death of your save file. My advice? Export your save before you try to hit the limit. Keep a "clean" version where the numbers still move. There is nothing more boring than a game where the currency is infinite and the prices don't matter anymore.
To keep your game running smoothly as you approach the septendecillion range, make sure you're disabling fancy graphics and milk animations. The math is heavy enough; don't make your GPU suffer while your CPU tries to calculate how many septillion cookies a single mouse click is worth. Turn off the "Particles" setting in the menu—it'll save your browser from crashing when you hit a big combo.
Focus on your sugar lumps. They are the only truly "finite" resource that limits your progress toward the technical ceiling. You can't click your way to more lumps (mostly), so time is the only real currency left in the late game.
