About this game

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.

A classic deck builder that doesn't force you to grind levels or watch excessive ads. Even has a short but enjoyable enough story. My biggest complaint is that makes it hard for you to see your own cards without excessive clicking to zoom in on them. When you're first to discard it a card after a draw you can be stuck unable to tell what the new card was to decide whether or not you want to discard it since it won't let you zoom in on it first

Love this game. Started with the actual card game which referred me to the iOs app. I have put a lot of time into the game and enjoy it still. Issues with the app is it gets very buggy. Does weird things that dont neccesarily make sense. With that there is also a level up mechanic that doesnt work for my account. I have played enough to get most of the levels. I have beaten all campaign levels with objectives except for the last one seems almost impossible. Great game just wish they would fix it

Game is fun. I installed this because I ordered the actual card game from Amazon, and I wanted to learn and practice the gameplay before it arrived. In that respect it was okay. The tutorial wasn't the best; I had to go on YouTube and watch someone do a playthrough to fill in the gaps. Once I got the basics down though, it was a lot of fun. The one thing that REALLY bothered me though is that you have to buy a full version to do almost everything. Just say that upfront.
