About
The Devil Card is a solo versus card battle game played on a 3×3 grid, inspired by Final Fantasy VIII’s Triple Triad.
Each match begins with you selecting five cards from your collection. Each card has four numeric values, one on each side, which determine its strength against adjacent cards. You take turns placing cards on the 3×3 Grid. When a card is placed next to an opponent’s card, the numbers on the touching edges are compared. If your card’s value is higher, the opponent’s card is flipped and changes color to indicate which side currently owns it.
Battles are played over two rounds, with all nine grid cells filled each round. At the end of a round, the side controlling the most cells wins that round. In case of a draw, the round is replayed and no side is awarded the win. Winning both rounds allows you to choose one card from your opponent’s deck to add permanently to your collection. This process repeats across the campaign, gradually expanding your deck and enabling more complex strategies in later battles.
Each opponent in the campaign can use a unique combination of official rules. The game includes the following rulesets:
Open: All cards are visible from the start.
Random: Card positions are shuffled at the beginning of each round.
Mirror: Cards with the same values touching each other are flipped.
Plus: Cards are flipped when the sum of adjacent values matches another sum on the board.
Combo: Flipped cards may trigger further flips in chain reactions.
MirrorWalls: Functions like Mirror, but board edges act as A walls.
Elemental: Cards have elemental types, with strengths and weaknesses influencing flips.
Each battle’s rules are clearly visible before the match starts, and in Freeplay mode, you can enable any combination to practice or create custom challenges.

The Campaign mode tells a linear story in which you face 25 unique opponents.
Each opponent uses their own set of rules, keeping battles varied and challenging you to adapt your strategy each time.
By winning duels, you unlock cards from your opponents’ decks, gradually expanding your collection.
There are over 300 unique cards to collect in total, so completing your collection may require multiple battles and careful strategic choices.
As you progress, you learn to master the different rules and build increasingly effective strategies to tackle tougher challenges.
Your ultimate goal is to defeat the Devil, earn his soul card, and complete the campaign.

In Freeplay mode, you can use all the cards unlocked in the campaign and freely configure the rules for your battles.
This mode does not affect the story’s progression and is ideal for testing strategies, experimenting with rule combinations, or simply playing at your own pace.

Reviews
This is a great card battler that's easy to learn but has enough depth to keep things interesting. I thought it would be easy at first because I kept winning, but it quickly became more challenging and had me thinking carefully about my strategies and card choices. I also liked the character designs and bits of lore throughout the campaign. I haven't played Triple Triad, so I'm judging this on its own and I really enjoyed it. Definitely recommend!
A really cool little card battler for anyone who loved Triple Triad. The rules are simple, matches are fast, but there’s enough strategy and rule variation to keep things interesting. I also really appreciate the transparent AI statement, but honestly I’m here for the gameplay, and the game delivers. It feels fairer than Triple Triad in some ways, because you’re not just abusing overpowered cards all the time. You actually have to think, adapt, and build your deck step by step. A small, focused indie game with charm, good mechanics, and a very fair price. Easy recommendation.
J'aime bien découvrir des jeux fait par des petits studio indés, je découvre celui ci avec plaisir. ( Content qu'il fonctionne parfaitement sur mon vieux pc avec ubuntu. ) Je ne connaissais pas ce genre de jeu de cartes, c'est vite prenant par son côté stratégique et l'évolution des possibilités au cours des différentes parties rend le jeu passionnant, ça donne envie de continuer. Bonne occasion de chasser le diable à coup de cartes !
A clever card battler clearly inspired by Triple Triad, but with its own identity. The 3×3 grid system makes every move matter and turns simple rules into surprisingly deep strategy. Matches are quick, addictive, and perfect for short play sessions. The game has a nice minimalist style that keeps the focus on tactics. A great pick if you enjoy strategic card games and satisfying card-flipping mechanics.
Even tho it uses Ai (WHich I love the transparent statement) . Im here for the gameplay. Thanks for giving me a copy I play it from time to time. It also is fairer than Triple Triad because you are not abusing with OP cards all the time :)
A smart twist on solitaire with roguelike elements. Runs are short and very satisfying, and I loved the character design which has a lot of charm. It’s clearly a modest production, but with clear focus and solid mechanics. The low price makes it an easy recommendation.
If you were into FFVIII triple triad, you should try this game. The game introduce rules variation that keep the matches interesting. You collect cards by defeating opponents (you can choose one of the card they used) , and you can replay against previous opponent multiple time in order to get a usefull card needed to defeat the next challenge. The game can be really challenging if you don't play by the additional rules for some encounters. The only thing I regret (but hard to do on a game of that scale) is I did not feel a strong bond with characters in the game (I remember when you aquired a challenging boss card in triple triad, you were exited to add it to your deck and spend many hours playing instead of continuing the story). Long story short it's worth it for the price if you are like me and want to play triple triad but dont have time to grind FFVIII again!
I didn’t expect to get hooked this quickly. I kept telling myself I’d play one more match, but every game made me want to try a different strategy or tweak my deck.
The Devil Card has a surprisingly deep strategy system for fans of tactical card games. Building a collection of over 300 cards, experimenting with different rule sets, and planning card placement on the 3×3 grid creates meaningful decisions every match.
This one's a really fun card battler, and I personally found the gameplay to be very addictive. The campaign kept me hooked, and the difficulty ramps up nicely as you progress. Collecting new cards is satisfying, and there's plenty to unlock. Great value for the price too!
