Slay the Spire

Slay the Spire is a genre-defining single-player roguelike deckbuilder in which players climb a multi-floor spire, building a deck card by card through combat rewards, shops, and events. Each playable character has a distinct card pool and set of archetypes, and powerful relics dramatically reshape strategy over the course of a run. The game is renowned for its elegant design, deep synergies, and near-infinite replayability, and is widely regarded as the title that popularized the roguelike-deckbuilder format. Tough enemy and boss encounters demand careful deck-thinning and forward planning. Its influence is visible across the deckbuilding games throughout this list.
