About Cthulhu Realms

Star Realms has gone insane! Introducing Cthulhu Realms! Are you zany enough to play the crazier and creepier cousin of Star Realms?

Download and play today to find out why Cthulhu Realms is so crazily addictive!

In Cthulhu Realms, each player tries to drive their opponent insane or have more sanity than their opponents when the deck runs out.

“Cthulhu Realms plays a lot quicker than most other deckbuilding games that I’ve played.” Roll for Crit

"I had a good time with this. I enjoy. I give it two insane people's screams up" - The Dice Tower

How to Play the Game:
Each player starts the game with a small deck comprised of initiates, goons and followers. Five cards from the deck form a row of available cards on the table; with more than two players, place three available cards between each pair of players.

Each turn, you start with five cards in hand, playing those cards in order to put locations into play, boost your own sanity or reduce that of others, collect conjuring power to acquire new cards, and remove cards from the game. You can use the power of your locations once each turn. At the end of your turn, discard any cards still in hand and all entities and artifacts that you played.

If you lose all of your sanity, you're out of the game. If you're the only one at the table who's still sane, you win. Otherwise, the game ends when the deck runs out and whoever has the most sanity wins.

Currently 1 star because I can't start up the app at all, my phone keeps saying it's "Cthulhu Realms keeps stopping" it allows me to go into settings or the links for posts but if I go into a campaign, or Vs AI, it'll say the error message.
