Achievement

This page contains information that will be applicable in future updates, and may not be applicable to the current release of Cookie Clicker.

File:AchievementsEaster.png

All achievements in the version 1.0466.

Achievements are badges you earn for achieving certain goals, and each one increases the amount of milk you have. They were introduced in version 1.026; as of version 1.0465, there are 157 normal achievements and 10 'shadow' achievements (plus 2 normal achievements and 2 shadow achievements only obtainable in the Dungeons beta). Normal achievements increase milk percentage by 4% each, so the maximum is 628% milk; shadow achievements do not affect milk.

The number shown on the Stats page includes all Normal Achievements (which are all earned by default) as well as any Shadow Achievements you have earned (which are uncounted until you earn them). For example, if you have 100 Normal Achievements and no Shadow Achievements, you would see 100/157 on the Stats page. If you then completed 5 Shadow Achievements, the number would change to 105/162, since the Shadow Achievements only counted after you achieve them.

Speed Baking III with Santa's Legacy and reindeer during first x7 frenzy

The following 10 achievements do not count towards the Milk percentage, nor will they show up on the stats tab until you have achieved them.

Icon	Name	Description	ID
	Negative void	Reset your game with 1 nonillion cookies baked. "You now have so few cookies that it's almost like you have a negative amount of them."	165
File:CheatedCookie.png	Cheated cookies taste awful	Hack in some cookies.	70
File:GodComplexNew.png	God complex	Name yourself Orteil. "But that's not you, is it?"	159

	Hardcore	Get to 1 billion cookies baked with no upgrades purchased.	92
File:SpeedbakingI.png	Speed baking I	Get to 1 million cookies baked in 35 minutes (with no heavenly upgrades).	93
File:SpeedbakingII.png	Speed baking II	Get to 1 million cookies baked in 25 minutes (with no heavenly upgrades).	94
File:SpeedbakingIII.png	Speed baking III	Get to 1 million cookies baked in 15 minutes (with no heavenly upgrades).^{[shadowachievements 1]}	95
File:Ghost-Mouse.png	True Neverclick	Make 1 million cookies with no cookie clicks.^{[shadowachievements 2]} "This kinda defeats the whole purpose, doesn't it?"	78
File:JustPlainLucky.png	Just plain lucky	You have 1 chance in 500,000 every second of earning this achievement.	104

↑ Note: Santa can not help you in Speed Baking when it is not Christmas SeasonThis achievement is technically not impossible; you get the achievement with Clicking Frenzy as the first Golden Cookie - or the second one, if you are lucky enough to have it appear before the deadline passes. This will give you enough cookies if you click fast enough. If playing during the Christmas season, you can get Santa's legacy and reindeer. Since upgrading Santa starts out cheap, it's possible get the achievement if you unlock Santa's Legacy, which gives you 10% multiplier per santa level, then with the first Golden Cookie x7 multiplier (which appears often); if you have it and a reindeer during the frenzy, you can easily unlock at least one Alchemy Lab. Other Santa upgrades, like Toy Workshop and Improved Jolliness, will also help in obtaining the achievement. There is an intermediate way to get this achievement. It involves cheating, but does NOT earn you the Cheated Cookies shadow achievement. If you change the time on your computer's clock it will also change the time on the game.
↑ You may click Golden Cookies, just not the Big Cookie. Start by clicking enough Golden Cookies to earn "Lucky!" twice. This gives you 26 cookies for free, just enough to buy a single cursor (and Heavenly chip secret if you have it) and start baking at least 0.1 CpS, gradually building up from there.
Otherwise you could just cheat them in, which also grants you the Cheated cookies taste awful achievement; a slightly less dishonest variant is to combine these methods and use cheats to spawn Golden Cookies.
Unlocking the "True Neverclick" achievement will also unlock the "Neverclick" achievement if you didn't unlock it before. Note that you do not need to build up a 1-million cookie "bank balance" to unlock this achievement, merely bake that many (even if you spend them immediately).

Notes

↑ You can easily get the "Cookie-dunker" achievement by re-sizing the browser window (make sure that Milk is turned on in the Menu).
↑ The tiny cookie is one of the four cookie icons in the "General" section on the Stats page.
↑ ^3.0 ^3.1 ^3.2 ^3.3 Unlike the Golden Cookie achievements, the Wrinkler and Reindeer achievements are counted in a single game, not all time: Doing a soft reset will reset the counter.

[5] You may click Golden Cookies, just not the Big Cookie. Start by clicking enough Golden Cookies to earn "Lucky!" twice. This gives you 26 cookies for free, just enough to buy a single cursor (and Heavenly chip secret if you have it) and start baking at least 0.1 CpS, gradually building up from there.
Otherwise you could just cheat them in, which also grants you the Cheated cookies taste awful achievement; a slightly less dishonest variant is to combine these methods and use cheats to spawn Golden Cookies.
Unlocking the "True Neverclick" achievement will also unlock the "Neverclick" achievement if you didn't unlock it before. Note that you do not need to build up a 1-million cookie "bank balance" to unlock this achievement, merely bake that many (even if you spend them immediately).

[cookiedunker-1] You can easily get the "Cookie-dunker" achievement by re-sizing the browser window (make sure that Milk is turned on in the Menu).

[tinycookie-2] The tiny cookie is one of the four cookie icons in the "General" section on the Stats page.

[reset-3] 3.0 ^3.1 ^3.2 ^3.3 Unlike the Golden Cookie achievements, the Wrinkler and Reindeer achievements are counted in a single game, not all time: Doing a soft reset will reset the counter.
