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.

Playtest content available:

- 60 demon cards that swap, copy, mark, weaken and rewrite your hand

- 16 enemies and bosses, each with its own rules to learn and break
