For the same building in Cookie Clicker Classic, see Grandma (Cookie Clicker Classic).

The Grandma is the main antagonist of Cookie Clicker Classic and the 1.0 Update, and the second cheapest building you can purchase with an initial cost of 100 cookies. She produces cookies at a base rate of 1 cookie per second.

Unlike the Cursor and Farm, Grandmas progress with later buildings very well with the grandma type upgrades, most of which double its efficiency but require 15 or more of a superior building to purchase, and sometimes can be quite expensive, up to 7,500,000,000,000 cookies for Rainbow Grandmas. After all upgrades, each grandma has a CpS of 104857.6 cookies per second herself, not counting the bonuses from One mind, Communal brain sweep, and Elder Pact.

Once you have unlocked 7 grandmas, you unlock the Bingo Center/Research Facility, which (as of 1.036) is currently the only upgrade to make a building four times as efficient, although its price of 1,000,000,000,000,000 cookies means it'll be a while until it's worth the cost. This will unlock a new upgrade after 30 minutes (research only starting once the last item researched is purchased), including five multiplier upgrades (Specialized Chocolate Chips for +1% and costing 100,000,000,000 cookies, Designer Cocoa Beans for +2% and costing 200,000,000,000 cookies, Underworld Ovens for +3% and costing 800,000,000,000 cookies, Exotic Nuts for +4% and costing 3,200,000,000,000 cookies, and Arcane Sugar for +5% and costing 12,800,000,000,000 cookies), one upgrade to double Grandma efficiency (Ritual Rolling Pins for 400,000,000,000 cookies), and three upgrades to greatly increase Grandma output but start the Grandmapocalypse (One Mind for 1,600,000,000,000 cookies and Communal Brainsweep for 6,400,000,000,000 cookies, which each give each grandma +0.02 base CpS per grandma, and Elder Pact for 25,600,000,000,000 cookies which gives each grandma +0.05 base CpS per portal. After all the doubling upgrades those figures are a LOT higher than that.)

In theory, fully upgraded Grandmas are the most efficient building a player can buy because they have a CpS based on the number of Grandmas purchased. That is, the Grandma's CpS rate increases as a square where other CpS rates increase linearly. However, the crossover point where Grandmas outperform the best other building, the Chancemaker, requires purchasing so many grandmas that it is impossible even via cheating, since the price would be much higher than JavaScript (which Cookie Clicker is written in) can store.

Each fully upgraded grandma produces cookies according to the following formula:

(0.8 + \frac{\text{Grandma Count}}{25} + \frac{\text{Portal Count}}{20}) \times (262,144)
or
209,715.2 + 10,485.76 \cdot (\text{Grandma Count}) + 13,107.2 \cdot (\text{Portal Count})

The Bingo Center/Research Facility can also unlock new upgrades for grandma. Although these upgrades can make grandmas more powerful, they would unlock the Grandmapocalypse as well. The following is a list of all upgrades for Grandma, unlocked in the Bingo Center/Research Facility. Once the Bingo Center is purchased, the Ritual Rolling Pins will be unlocked 30 minutes later and when those are purchased the next upgrade will be unlocked 30 minutes later and so on.

Background changes during GrandmapocalypseEdit

Main article: Grandmapocalypse

Changes from one stage to another can be obtained by the One Mind, Communal Brainsweep and Elder Pact upgrade. Once they're appeased, the background will change back to normal temporarily. When the Grandmatriarchs are appeased, the store icon will change back to normal.

Store icon changes during the GrandmapocalypseEdit

Since version 1.0393, the store icon for Grandmas will change depending on the state of the Grandmapocalypse.
