About This Game

Ruinous is a medieval fantasy roguelike deckbuilder where every choice shapes your fate. 

Inspired by the card game Scoundrel, Ruinous transforms simple rules into a deep, build-driven strategy experience filled with cursed cards, unique bosses, and wildly satisfying combos.

Choose your hero. Carve your path. Break the game.

Face ruthless bosses, each ruling their own domain with deadly modifiers. Adapt your strategy, craft powerful card synergies, and progress through a branching roguelike map where every decision could lead to triumph… or ruin.

  • Fight through dungeons that test your strategy

  • Collect and enchant cards to enhance your deck

  • Purchase over 100 unique charms and items to refine your build

  • Confront 10 unique Bosses, each with powerful rule-changing abilities

  • Play as 6 different heroes each with unique abilities and playstyles

Every run offers new paths, new builds, and new ways to dominate.

  • Add new cards to grow your deck

  • Enchant cards with powerful effects

  • Cast spells to destroy enemy cards

  • Use potions and items that grant new opportunities

Find, loot, and purchase unique charms and relics to craft a build that fits your playstyle.

Stack effects, chain triggers and discover combinations that feel unfair in the best way.
