Diamond Head, Polden Publishing
A roguelike twist on solitaire: counter enemy cards, unleash demonic powers, gather relics, and blow up the screen with devastating combos as you fight your way through the Kingdom of Fools.

Fabulous Fool blends solitaire-style card logic with roguelite deckbuilding, creating a fast-paced experience built on the classic depth of the genre.
Collect powerful relics, unleash eccentric demons, and craft bizarre, rule-breaking synergies that twist the game’s logic and turn every fight in your favor.
60 unique demon cards that mark, empower, alter, copy, weaken, and let you manipulate your cards in countless ways.
50 relics and consumables that shape your build, swing impossible fights, and give you the tools to turn defeat into triumph. No winning run goes without them.
16 enemies and bosses. Each foe fights with its own logic, modifiers, and unfair tricks. Learn their rules… then turn those rules against them.
6 event characters who may reward you, deceive you, or challenge you to a sudden fight — high-risk encounters that can either empower your build or completely derail it.
4 complete Acts, each featuring its own map, enemy roster, event characters, and signature encounters.
Every journey offers new picks, new synergies, and new surprises.

Welcome to the Island of Fools — a strange land where every inhabitant follows the crooked logic of a twisted card game.
To survive here, you must master the rules, bend them, break them, and outplay everyone who stands in your way… all the way up to the enigmatic King of Fools.
Step into the uniquely absurd world of Fabulous Fool, where the rules twist, the island shifts, and nothing stays ordinary.
