One Deck Dungeon is a card game "roguelike" — a dungeon delve that is different every time, difficult to survive, with a character you build up from scratch. The deck consists of various foes to combat and other perils from the dungeon.
Each card, though, depicts both the obstacle to overcome and the potential rewards for doing so. When you defeat a card, you claim it as either experience, an item, or a skill, tucking it under the appropriate side of your character card to show its benefits.
