Typical occurrence of the Grandmapocalypse during the final stage, version 2.0.

The Grandmapocalypse is an endgame event. The Grandmapocalypse affects both the 1.0 Update of the game, as well as the pre-update version. It affects the appearance of the game window and causes spawning of Wrinklers and Wrath cookies.

Starting the GrandmapocalypseEdit

To start the Grandmapocalypse, you must have at least seven Grandma types, and at least seven grandmas. You will then have access to the Bingo center/Research facility. This will allow you different research/upgrades and eventually the "One Mind" Upgrade. This will give you a warning message, and if allowed will start the Grandmapocalypse.

Stage 1Edit

Once "One Mind" is purchased,  the Grandmapocalypse begins. The Grandmas are now considered "Awakened". Wrath cookies will appear 33% of the time, and Wrinklers will appear as well. The Grandmatriarchs will start to have sharp teeth.

Stage 2Edit

To get to the next stage, follow the Research Upgrades until you buy the "Communal Brainsweep" Upgrade. The Grandmatriarch Status will change to "Displeased." Wrath cookies will appear 66% of the time, and Wrinklers will appear faster. The Grandmatriarchs are tinted red and have glowing eyes.The Grandmatriarchs will also have sharper teeth.

Stage 3Edit

To get to the Final Stage of the Grandmatriarch form, you must follow the Research Upgrades up until you buy the "Elder Pact." Another warning message will appear. The news broadcasts will turn into reports of the world ending, and the Grandmatriarch Status will change to "Angered." Golden cookies will be entirely replaced by Wrath cookies at this stage. Wrinklers appear even faster. The Grandmatriarchs show their true form as demonic masses of flesh in the background.

Halting the GrandmapocalypseEdit

Once Elder Pact is purchased, the Elder Pledge switch is unlocked. Elder Pledge puts a temporary hold on the Grandmapocalypse and unlocks the Elder Covenant switch. When the Grandmapocalypse is halted or ended, the Grandmatriarchs' state of mind becomes "appeased". This changes the background into the original blue, makes only Golden Cookies appear, pops all wrinklers, and reverts the news ticker to normal messages.

The Elder Covenant is worth exactly 66.6 trillion cookies. It puts an indefinite hold to the Grandmatriarchs' wrath. This purchase results in a 5% reduction of your CpS, and locks the Elder Pledge switch. In order to return to the chaotic state of the Grandmapocalypse and restore your CpS, the Elder Covenant can be revoked at a cost of 6.66 billion cookies.

The Elder Pledge will put the genocidal grandmas to rest for 30 minutes. Every time an Elder Pledge is bought, the price goes up by a factor of 8, capping at 4.4 trillion. After pledging 10 times, Sacrificial Rolling Pins is able to be researched. It doubles the time of peace, making it an hour-long.

The Grandmapocalypse can also be stopped by selling all of your grandmas. Doing this causes the Grandmatriarchs' status to disappear from the Stats page. Buying at least one grandma will restart the Grandmapocalypse at the stage you left off.

Background changesEdit

As the Grandmapocalypse goes on, the Grandmatriarchs grow increasingly angry with each Bingo Center/Research Facility related upgrade. This is reflected in the backgrounds:

A profitable strategy involves stopping progression of the Grandmapocalypse after One Mind (i.e. buying Exotic Nuts, but not Communal Brainsweep). This holds the status of the grandmatriarchs at awoken, and allows for golden cookies to spawn alongside wrinklers, albeit with the occasional red cookie. Since each Wrinkler returns 1.1x all cookies eaten while they were present, rather than just the cookies that one ate, if you let 10 Wrinklers eat cookies for an extended period, when you pop them you will end up with a total of 6x as many cookies as you would normally get. Mixed with the frequent x7 Frenzy production from clicking Golden Cookies, the result is an average CpS that is over 10x your natural CpS. And since the "Lucky" golden cookie bonus is not affected by Wrinklers, you will still get the full amount from a "Lucky" bonus while you have the Wrinklers. In addition, you can also get the x666 Elder Frenzy, which will stack with your Wrinklers and give more cookies. For pure CpS speed, this is the best strategy.

It takes an average of 54 minutes, 14.4 seconds for all 10 Wrinklers to spawn during "awoken" status, 27 minutes, 7.2 seconds during "displeased", and 18 minutes, 4.8 seconds during "angered".

If you are very dedicated to the game, an advanced playstyle is to purchase everything up to Elder Pact, but not the Pledge or Covenant. This strategy hinges on a mechanic called "eldeer" - when a Reindeer appears during a x666 Elder Frenzy. The reason this requires constant activity and monitoring is because you will want to synchronize your wrath cookies and Reindeer. If a cookie is on screen, wait until it is either almost completely faded out or a Reindeer is on screen before clicking it. Always wait until a Reindeer is at the far right of the screen, over the buildings panel, before clicking it. This encourages cookies and deer to line up, and eventually you will hit the jackpot. Even if it isn't Christmas, and you don't have the Season Switcher upgrade, or you are trying to get Easter eggs, Halloween cookies, or Valentine's Day cookies, buying the Elder Pact, and thus having more wrath cookies, can be profitable just due to the Elder frenzy.

An often-overlooked factor is the usefulness of wrinklers to get seasonal upgrades. Halloween requires you to pop wrinklers to get its cookies, and wrinklers also can give you Easter eggs. For this reason, some people may choose to buy the Elder Pact, which causes wrinklers to spawn faster, even if they prefer Golden Cookies to Wrath Cookies.

Only if you use a full autoclicker (250+ clicks per second) is Pledging even remotely better than One Mind or Elder Pact. Although you have full golden cookies, you give up Wrinklers and their respective 6x CpS boost. If you prefer golden cookie gains, but also like to get lots of cookies, stopping at One Mind is far better. As said before, the higher Frenzy-Lucky chances are only beneficial if you use the max autoclick settings - other than that, the Wrinkler loss is not worth it.

Never, ever use the Covenant. Since all the golden cookie rewards (the only reason you would use the Covenant at all) are all CpS dependent, giving up your CpS to use them is illogical. If you must end the Grandmapocalypse, Pledging is much, much better. Exception: You can use Covenant to cancel a Pledge if it has a long time remaining and you need to go AFK. Simply get Covenant and then immediately revoke it. The Pledge will be cancelled and wrinklers will start to appear, quickly regaining the cost of doing this.

Since the 2.002 update, it has become even more beneficial to remain in Stage 1 Grandmapocalypse (One Mind without Communal Brainsweep) than proceeding to Stage 3. The primary draw of Stage 3 is the higher occurrence of Elder Frenzies. Originally, triggering an Elder Frenzy would cancel and replace any Frenzy or Clot effect already active, meaning that the prevalence of Wrath Cookies alone determined the relative effectiveness of Elder Frenzies. With 100% Wrath Cookies, Stage 3 had 3 times the benefit from Elder Frenzy than Stage 1 did. Since the update, however, Elder Frenzy will now stack with Frenzy and Clot. Assuming that these effects are active about half the time during the Stage they are most common in, we have:

  • In Stage 3, half of all Elder Frenzies will overlap with a Clot and be cut in half, while the other half will go as normal. This leaves$ 0.5E + 0.5(0.5E) = 0.75E $, with E being a full Elder Frenzy. This means that Elder Frenzies are now only three quarters as effective in Stage 3 as they were before the update.
  • In Stage 1, Wrath Cookies only appear 1/3 of the time, so start at 0.33E instead of E; after that, half of all Elder Frenzies will overlap with a Frenzy and be multiplied by 7, while the other half will go as normal. This gives$ 0.5(0.33E) + 7(0.5(0.33E)) = 1.33E $, meaning that Elder Frenzies are now 4 times as effective in Stage 1 as they used to be, overall being almost twice as effective as Stage 3 Elder Frenzies in the long run, despite being so much rarer an occurrence.

Subtle variations can be made for Clot occurring occasionally during Stage 1 and the presence of Dragon Harvest with Krumblor's Reaper of Fields aura, but will not alter the proportional effectiveness significantly.

History Edit

Cookie Clicker v1.03Edit

The Grandmapocalypse returned alongside various other grandma-related updates in version "1.03", which was then quickly updated once again with only Grandmapocalypse-related updates in version "1.031". It is triggered after buying the "One mind" upgrade from the Research Facility, and is furthered by buying "Communal brainsweep" and finally "Elder Pact".


A typical occurrence of the Grandmapocalypse in version 1.031, during the final stage.

Known effects of this event include the background changing into a painting of grandmothers slowly acquiring a demonic appearance and the Wrath Cookie occasionally (or once angered enough, always) appearing instead of the Golden Cookies. In stats page "Special" section which, among other things such as the research progress from the Bingo center/Research facility, indicates the grandmatriarch's mood, from "Awoken", to "Displeased" and finally "Angered". In the version 1.0393, the Grandmas in the Store section of the game start turning creepy and Wrinklers, leechlike creatures that decrease CpS (cookies per second) until popped, will start to appear.

In Cookie Clicker ClassicEdit


An example of the first stage of the Grandmapocalypse


When you hit 1,000,000,000 cookies, the final stage will be activated

The Grandmapocalypse starts once you've accumulated over 1,000,000 cookies. The screen becomes covered in a shaking, flashing, tiled background of grandmas. As you gain more cookies, the Grandmapocalypse becomes more intense, with more images of different grandmas of various sizes and intensity. Sometimes the background can stretch or can shake very hard. The Grandmapocalypse background is made with the grandma image from the shop on the right. If you cheat by adding over 1,000,000,000 cookies, you'll start to enter the 3rd stage of the Grandmapocalypse. Example: Having infinite cookies (1e,+99999) will bring you to the 3rd stage of the Grandmapocalypse.

The Elder PledgeEdit

The Grandmapocalypse can be temporarily halted by purchasing the Elder Pledge, an upgrade which becomes available after accumulating over 2,000,000 cookies. It's like a neat kind of Grandmapocalypse Removal System.  The first iteration of this upgrade costs 666,666 cookies and increases the effectiveness of your clicking, and boosts the CpS of your grandmas based on your number of portals. Tip: Turn flashing off so you can't see the Grandmapocalypse background.

The boost in CpS from purchasing the elder pledge can be a huge gift in the beginning of the end game of Cookie Clicker.  Players can increase their clicking output by over 100x with enough cursors which can give a huge boost to cookie output when saving for additional Portals or the coveted Time Machine.

  • Sometimes, switching windows can cause the grandma background to get 'stuck' in its current state until you buy another upgrade that changes it. (Does not work anymore in version 1.0375)

The Grandmapocalypse! Part 2

  • Elder Covenant used to cost 666 trillion, and trillions back in the day were really hard to obtain and instead of 5% CpS loss it was 20%, so it was a lot harder to get it and get more cookies with it.

  1. Purchasing the One mind upgrade triggers the beginning of the Grandmapocalypse.
  2. Elder Pledge is unavailable while Elder Covenant is in effect.
  3. 3.0 3.1 Unlike most "number of actions" achievements, the Wrinkler and Reindeer achievements are counted in a single game, not all time: Ascending will reset the counter.
