Cookie Clicker Wiki

The Idleverse is a building added in the alternate reality update. It is the eighteenth building in the game, costs 12 sextillion cookies and produces 8.3 trillion CpS by hijacking production from other idle universes. It is currently the most efficient building.

"While the ethics of ransacking parallel universes for their riches may seem questionable to some, you've reasoned that bringing the good word of your cookie empire to the unwashed confines of other realities is your moral duty, nay, your righteous imperative, and must be undertaken as soon as possible, lest they do it to you first!"

"The structure of the metacosmos may seem confusing and at times even contradictory, but here's what you've gathered so far:
  • each reality, or "idleverse", exists in parallel to all others"
  • most realities seem to converge towards the production of a sole type of item (ours evidently being, thanks to you, cookies)
  • each reality is riddled with chaotic tunnels to a number of subordinate dimensions (such as the so-called "cookieverse"), much like swiss cheese
  • all realities bathe in an infinite liquid of peculiar properties, colloquially known as "milk"

Finally, each reality may have its own interpretation of the concept of "reality", for added fun."

"It's quite nice that you can rewire the logic of each universe to generate cookies instead, but you still end up with parsec-loads of whatever they were producing before - baubles you've long made obsolete: cash money, gems, cheeseburgers, puppies... That's why you've designed the universal converter, compatible with any substance and capable of turning those useless spoils of conquest into the reassuring crumbly rustle of even more cookies."
Chalcedhoney idleverse.png Multiverse agents Own 50 idleverses Money.png 600 septillion Idleverses are twice as efficient.
"You can send undercover spies to infiltrate each universe and have them signal you whether it's worth overtaking. Once the assimilation process started, they will also help pacify the local populations, having established trust through the use of wacky, but seamless, disguises."
Buttergold idleverse.png Escape plan Own 100 idleverses Money.png 60 octillion Idleverses are twice as efficient.
"You've set an idleverse aside and terraformed it to closely resemble this one in case something goes horribly wrong in here. Of course, the denizens of that idleverse also have their own escape idleverse to abscond to in the eventuality of your arrival, itself likely having its own contingency idleverse, and so on."
Sugarmuck idleverse.png Game design Own 150 idleverses Money.png 6 nonillion Idleverses are twice as efficient.
"Each idleverse functions according to some form of transcendental programming, that much is a given. But they also seem to be governed by much more subtle rules, the logic of which, when harnessed, may give you unparalleled dominion over the multiverse. Rewrite the rules! A game designer is you!"
Jetmint idleverse.png Sandbox universes Own 200 idleverses Money.png 6 decillion Idleverses are twice as efficient.
"It doesn't seem like you'll run out of extra universes anytime soon so why not repurpose some of them as consequence-free testing grounds for all your more existentially threatening market research? (...consequence-free for you, anyway.)"
Cherrysilver idleverse.png Multiverse wars Own 250 idleverses Money.png 6 undecillion Idleverses are twice as efficient.
"Hmm, looks like some other universes wised up to your plundering. Thankfully, that's nothing your extra beefed-up metacosmic military budget can't handle!"
Hazelrald idleverse.png Mobile ports Own 300 idleverses Money.png 6 duodecillion Idleverses are twice as efficient.
"Accessing each outer universe is a bit of a hassle, requiring the once-in-a-blue-moon alignment of natural cosmic ports to transit from universe to universe. You've finally perfected the method of travel near-instantaneously along universal perimeters to permit headache-free multiverse connections. Took you long enough."
Mooncandy idleverse.png Encapsulated realities Own 350 idleverses Money.png 6 tredecillion Idleverses are twice as efficient.
"Untold feats of science went into the reduction of infinite universes into these small, glimmering, easy-to-store little spheres. Exercise infinite caution when handling these, for each of them, containing endless galaxies and supporting endless life, is more precious than you can ever fathom. They've also proven to be quite a smash hit in your warehouses on bowling nights."
Astrofudge idleverse.png Extrinsic clicking Own 400 idleverses Money.png 60 quattuordecillion Idleverses are twice as efficient.
"If you poke an idleverse, it seems like it gets work done faster. It's also quite fun hearing a trillion terrified voices screaming in unison."
Alabascream idleverse.png Universal idling Own 450 idleverses Money.png 600 quindecillion Idleverses are twice as efficient.
"The nature of idleverses is found in waiting. The more you wait on an idleverse, the more exponentially potent it becomes - which saves you a whole lot of hard work. In a true act of zen, you've taken to biding your time when collecting new universes, let them ripen like a fine wine."
Iridyum idleverse.png Break the fifth wall Own 500 idleverses Money.png 6 septendecillion Idleverses are twice as efficient.
"Huh, was that always there? Whatever it was, it's gone now. And what was behind is yours for the taking."

  • Aside from the Grandma, the Idleverse is the only building to have a randomized appearance in the building overview. However, unlike grandmas, idleverses do not require upgrades in order to gain an altered appearance.
    • The Idleverse grandma type is also the only type of grandma to face left instead of right.
  • Idleverses have the longest building description in the whole game.
  • Many if not all of the achievements for Idleverses appear to be references to other IPs (intellectual properties, i.e. universes).
    • The "Unreal" achievement may be a reference to the Unreal game development engine.
    • The "Hyperspace expressway" achievement is a reference to the Vogons from The Hitchhiker's Guide to the Galaxy, as building a hyperspace freeway was why they destroyed the Earth.
    • The "You are inevitable" achievement is a reference to Thanos from the Marvel Cinematic Universe and his quote "I am inevitable."
    • The “Reject reality, substitute your own” achievement is a reference to the quote from the 1984 film The Dungeonmaster, “I reject your reality and substitute my own.” The quote is often said by Adam Savage in Mythbusters.
    • The 'Earth-616' achievement is a reference to Marvel Comics, where the prime universe that most of its stories take place in is known as Earth-616.
    • "Nobody exists on purpose, nobody belongs anywhere" and its flavor text "Come watch TV?" are part of a quote from the Adult Swim show Rick and Morty.
