Scoundrel's Dungeon

About this game

A Dungeon Made of Cards

Every floor of the dungeon is a deadly hand of Scoundrel - the classic solo card game. Four cards. One choice at a time. Pick up a weapon, fight a monster, drink a potion, or walk away. The rules are simple. The dungeon is not.

Fight Smarter, Not Harder

Your weapon follows the descending rule - each kill must be weaker than the last. Swing too early and your blade becomes useless. Go bare-handed and you'll pay in blood. Every card you touch is a decision between survival now and options later.

The Deeper You Go, the Worse It Gets

Each floor adds stronger monsters to the deck. Poisonous creatures that drain you room by room. Bleeding strikes that punish overkill. Thieves that steal from your bag. The dungeon learns. You need to learn faster.

Build Your Run

Level up by killing monsters and choose card upgrades. Turn a simple healing potion into a shield generator. Make your weapon more powerful. Buy passive items from the shop - a bag for spare weapons, a map to see the deck, a charm that lets you skip deadly rooms.
