In Cookie Clicker ClassicEdit

The portal is the third most expensive unit in the game. It will give you 6,666 cookies every 5 seconds, therefore increasing production rate by 1,332 cookies/second. It produces cookies 66.66 times faster than a Shipment.

Buying your first Portal will increase Grandma output by +5 cookies per 5 seconds. It will also cause C'thulhu-like creatures to replace some grandmas.

Because of the high base costs, the Portal isn't effective until many alchemy labs are purchased, and their price multiplied by 27 goes above 1 billion.  


  • The achievement "With strange eons" could be a reference to H. P. Lovecraft's fictional book, within the canon of the C'thulhu Mythos, the Necronomicon. In the Necronomicon, the line "That is not dead which can eternal lie. And with strange eons even death may die." is said to be included.
  • With the Elder Pact upgrade, each Grandma gets +0.05 base CpS for every Portal. Because of this, the Portal used to be the only building in the game that can directly affect the cookie output of other buildings which aren't the Cursors.
    • As of V2.0, the upgrade type synergy exists, which makes two building types affect each others cookie output directly.
  • The Portal used to only give 3,000 cookies every 5 seconds, but after Orteil heard people complain that it was underpowered, he raised it to 6,666.
  • The icon for the portal may be a reference to the Oblivion Gates from The Elder Scrolls 4: Oblivion. This seems very likely, since the gates were known for being alright to start with, but quickly bogged down by endless repetition.
    • Additionally, the "Deity-sized portals" upgrade may be a reference to Mehrunes Dagon from the same game, as he came through the Oblivion Gate and was shown to be the same size as Akatosh, the dragon God.
  • The name and description for the "Sanity dance" upgrade are references to the song "Safety Dance" by the band Men Without Hats, which includes the lyric "We can dance if we want to. We can leave your friends behind."
  • The achievement for getting 1 Portal, "A whole new world," is a reference to the song "A Whole New World" from Disney's Aladdin
  • The achievement for getting 50 Portals, "Now you're thinking", is a reference to the games Portal and Portal 2, as one of the series' taglines is "Now you're thinking with portals!"
  • The achievement for getting 200 Portals, "Realm of the Mad God", is a reference to the MMORPG  Realm of the Mad God. It could also be a reference to The Elder Scrolls 4: Oblivion, as Sheogorath was known as the Mad God, and his realm, the Shivering Isles was also referred to as the Realm of the Mad God.
  • The name and description of "Maddening Chants" upgrade "A popular verse goes like so : "jau'hn madden jau'hn madden aeiouaeiouaeiou brbrbrbrbrbrbr"" are references to game Moonbase Alpha, that features speech synthesizing of player chat and had become small Youtube hit. Some players would flood the chat with said parches in-game, including many others, for comical relief what some others would find frustrating. This could also be a reference to the chant featured in H. P. Lovecraft's 1926 story The Call Of C'thulhu, in which the cultists chant "ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn".
