About Fabulous Fool
A counter-card roguelike deckbuilder where you beat enemy cards with suits, ranks and trumps – then chain combo them and break the rules with demons.
THE ENEMY PLAYS FIRST
In Fabulous Fool, enemies attack you with cards. Beat each threat with a higher card of the same suit, or spend a trump to slip out of danger. Every hand is a small puzzle: match the right card to each threat, then play them in the order that sets up your next big move.
BEND THE RULES WITH DEMONS
Weave demons into your deck – special cards that rewrite how the table works. Swap a suit, copy a card, mark it, weaken it, flip a losing hand into a winning one. Demons are how you stop playing by the rules and start writing your own.
PLAN AND TRIGGER CHAIN REACTIONS
The best turns cascade. A single clever counter triggers a demon, which sets off a relic, which clears the table and dumps a wall of damage on your enemy. Line up your demons, relics and potions right, and one move becomes a devastating chain – and you built every piece of it!
BUILD A DECK THAT BREAKS THE GAME
Between fights, pick up relics, potions and hero abilities that push your run in a new direction. Chase suits, colors, ranks, or pure chain-reaction chaos. Win or lose, every run unlocks new demons, relics and heroes – and the next one plays nothing like the last.
WELCOME TO THE KINGDOM OF FOOLS
All of this unfolds on a fog-wrapped island where card rules are the laws of reality: cunning demons, a Cursed King, a mysterious Organizer, and a tournament you were never meant to win. A funny, slightly absurd fantasy world that reveals itself the deeper you push.
