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.

"The art in Cthulhu Realms is hilarious and beautifully done, somehow complimenting the horror theme perfectly. The production value is top-notch."
— Gameosity

"It’s a surprisingly effective package that delivers a great little deck builder with a low price tag. If you can embrace the playful theme, you’ll find a pleasant gem in Cthulhu Realms."
— Geek Ken

"It certainly is not just another deck-building game, but has original and fresh mechanics that will challenge your brain."
— Board Game Maniac

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.

Darwin Kastle is the designer of the popular Star Realms Deckbuilding Game, and with the digital release of Cthulhu Realms, he once again provides tons of playability for free, and a one-time upgrade to be able play with your friends and more on any device.

Customer Reviews

Clumsy interface

This game is nearly if not exactly the same as star realms. I like star realms. However, unlike las the information representation is obtuse, the meter face is clumsy, and it is hard to survey the board and see what is going on. Given the competition, I see no reason to slog through a frustrating interface.

Also, the theme of Cthulhu realms doesn't make any sense. In star realms you were building a space empire and attacking, sometime blocked a by outposts - that makes sense. Here, you are investigators who are buying monster to haram each other's sanity. Why do the great old one do the bidding of a human? Why are the humans trying to drive each other insane? Why do location protect you from sanity loss? None of it makes sense.

Great fun

Sure the UI is not perfect, but it works well. Online play with others is implemented very well. App badge and notifications when it is your turn. It is easy to setup game and quick to check if it is your turn.
It is free to try, but anything worthwhile costs money. It is much cheaper than the real game. So quit complaining about a measly $5.

I highly recommend this game.

Cthulhu fhtagn!

A fun game that takes a lighthearted approach to the tentacle & madness filled works of H.P. Lovecraft. I loved reading those stories, and I'm really enjoying this challenging & entertaining game that builds on them. I agree with some of the other reviews that UI could be improved so cards are legible when choosing which to play or discard. But a solid game overall. Free to try, send the developers $5 if you want more. Totally worth it in my opinion.
