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!

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

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.

Cthulhu Realms reviews and comments

Translated by
Microsoft from Deutsch
Bad in many aspects: Art, even on high resolutions the art isnt well resoluted at all, i further dislike a lot of the card drawings. In my eyes the whole fun about Cthulhu direction makes it worse. Just a matter of taste ofcourse but overall the drawings arent that interesting or well done. Repetitive, the cards get boring quite fast. There arent many directions for your deck to go and after youve tried them all it wont get anymore interesting. There arent enough different cards in my eyes aswell. Graphics, are very basic. Even for being a card game presentation can be very well done. Looking at other card games that come from physical versions like the Lord of the Ring Living Card Game, Cthulhu is just too basic. It feels absolutely cheap. Just look at the screenshots of the digital version of the Realms Games, they are low resoluted, uninspired, plain bad. I rather recommend playing the games on a boardgame simulation engine (e.g. Tabletop Simulator) than with this app. In fact, i would rather have seen White Wizard hand over a licensed package to Tabletop Simulator to provide a "legal" way to play it there instead of making their own game in a low quality engine. Design, is also lacking and basic at best. The gameplay premise is ofcourse similar to the other Realms Games, but somehow here it misses a lot of what makes Hero Realms great and Star Realms interesting. Overall though, the UI is the worst. Its clunky, bad to use, just a pain in fact and wasting your time. We arent even talking about controls and layout being intuitive, thats a too high standard. I would be ok if it was just in some way usable and ok-ish. But it isnt. I could name a dozen points where design failed, an example would be to have the actions of your opponent popping up in white text on the right, no textbox to frame it and it also disappears instantly when a new action is taken. So its basically pointless, takes up a lot of space, just jumps into your picture all the time and so has pretty much no reason to be there at all. The used fonts are looking like low quality, buttons feel cheap and seem even misplaced. Overall, Cthulhu Realms is somewhat a nice idea in theory, but execution is horrific. Not only should they have stayed on a more serious tone (a Cthulhu Deckbuilding Game with a serious and horror-esque approach would in and of itself be amazing anyway), but also should they have invested more time to really make a polished transfer from physical to digital. As said, there are other examples of how this can be done properly. Talisman, LOTR LCG, The Witcher Boardgames, Gremlins Inc., even the very old Magic Games and the Dominion Online App seem much better. I recommend making new apps of their games they should give the contract to a different studio, because this one cant provide quality.
