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.

Enjoyable card game

I paid for the full version because I was enjoying the free one. Purchasing it didn’t give me a ton more to do other than to play random on-line games and unlock the hard levels (which aren’t really much different than the easy ones). Still, I’ve had a lot of hours of enjoyment. It’s a pity the developers don’t seem much engaged with it anymore as more levels and more features (rank ladders for on-line play... or just fix the current stats which are broken) would be awesome. Neat cards, nice mechanics, fun theme.

As someone who loves deck builders..

This was absolutely a letdown. Don't get me wrong, in execution, it wasn't bad. It's well enough made, despite complaints I think the UI is fine.
However, the AI is terrible. Easy AI is either too easy or way too hard, and hard is actually ridiculous to the point that it seems it's less RNG and more forced difficulty.
The tutorials are fairly weak, i'd say. If I weren't knowledgable about deckbuilders already, they would have left me more lost than before. Perhaps this is just my opinion though, as I was taught in person by friends.
Overall, the harsh rating is based more on comparison to other deckbuilders than in relation to the game itself. The game itself would only get a 3.5 from me, anyways.
If you have no one to play deckbuilders with in real life, or if you are just so obsessed with them that you need to play all the time, this is for you. Otherwise, wait til game night.

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.
