Plain idleverse Manifest destiny Own 1 idleverse Money 120 sextillion Idleverses are twice as efficient.
"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!"
Berrylium idleverse The multiverse in a nutshell Own 5 idleverses Money 600 sextillion Idleverses are twice as efficient.
"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."

Blueberrylium idleverse All-conversion Own 25 idleverses Money 6 septillion Idleverses are twice as efficient.
"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 Multiverse agents Own 50 idleverses Money 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 Escape plan Own 100 idleverses Money 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 Game design Own 150 idleverses Money 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 Sandbox universes Own 200 idleverses Money 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 Multiverse wars Own 250 idleverses Money 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 Mobile ports Own 300 idleverses Money 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 Encapsulated realities Own 350 idleverses Money 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 Extrinsic clicking Own 400 idleverses Money 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 Universal idling Own 450 idleverses Money 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 Break the fifth wall Own 500 idleverses Money 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."
Glucosmium idleverse Opposite universe Own 550 Idleverses Money 60 octodecillion Idleverses are twice as efficient.
"You've located a universe where everything is reversed: up is down, light is darkness, clowns are vegetarians - but worst of all, some lunatic there is manufacturing abominable amounts of anti-cookies. If these came into contact with yours, everything would be lost! Thanks to this discovery, you've been able to place the offending universe in permanent quarantine, and pray that there aren't more like it hiding around somewhere."
Glimmeringue idleverse The other routes to Rome Own 600 idleverses Money 600 novemdecillion Idleverses are twice as efficient.
"Did you know every idleverse follows its own path of sequential buildings, sometimes quite dissimilar to our own? Grandpas, wind turbines, through the power of music, friendship, or legislation; those folks in there discovered ways to make cookies out of any random venue. Some of them don't even have idleverses, can you imagine?"
