Cthulhu: Age of Madness

Cthulhu: Age of Madness , the card game of Cultists and Cosmic Horror, is on Kickstarter! Funded in 8 hours, 378% funded, 4th Stretch Goal nearly unlocked!

The Cosmic Veil has been pierced. The Elder Gods awaken from their ancient slumber in anticipation of a return to our realm. Cultists around the globe are mobilizing, preparing the Seals to open the Gates, hearkening the Elder Gods return. Their goal, to usher in the Age of Madness! Will you heed the Master’s Call?

Cthulhu: Age of Madness (C:AoM) is a competitive card game for 2-4 players, rooted in the lore of H.P. Lovecraft's Cthulhu Mythos.

In C:AoM, you don't play an Investigator, Reporter, or Student. You assume the role of an Elder God's cult, attempting to open the Gates, allowing your Elder God through, and ushering in the Age of Madness.


Open your Elder God's Gate by unlocking its four (4) Seals, allowing your Elder God to cross over to our dimension. Seals are unlocked with an Elder Sign, or with a Ritual Circle of four (4) Cultists of your Elder God.


Each Player chooses an Elder God and places its Card on the table in front of them. The Deck is then well shuffled, and five (5) cards are dealt to each Player.

On a turn, the Player performs two (2) Actions, and then draws up to their Hand Size. Unless modified by cards in play, Hand Size is five (5) cards. If the number of Cards in a Player’s Hand at the end of their turn is more than their Hand Size, they retain the cards, but do not draw any additional Cards.

Play continues clockwise, and ends when a Player has unlocked their fourth Seal, opening the Gate, and allowing their Elder God to usher in the Age of Madness.


Unlocking a Seal can be completed several ways. Playing, or Stealing, an Elder Sign unlocks a Seal. Completing a Ritual Circle of four (4) Cultists of your Elder God unlocks a Seal. When a Seal is unlocked, that Elder God’s Cosmic Primal Power is activated, and its powers take effect immediately.


Ritual Circles are the most common way to unlock a Seal in Cthulhu: Age of Madness. Ritual Circles are completed when a Player has a group of four (4) Cultists of their Elder God in their Pool. All the Cards in the Ritual Circle are then moved to the Elder God’s Card, unlocking a Seal. This does not count as an Action.


When a Convert Cultist card is played, the Player chooses a matching group of Cultists in any Player’s Pool, and converts them to Cultists of their own Elder God. This is indicated with the use of a Cultist Faction Card, placed horizontally on top of the Cultists, or by combining the Cultists with any matching Cultists already in the Player’s Pool. This card can be played on a Player’s own Cultists, or on an opponents Cultists.
