Slay the Spire fuses card games and roguelikes into a single-player deckbuilder that reinvents itself on every climb. Pick a character, start with a handful of basic cards, and build something far stranger and stronger as you fight your way up a tower full of bizarre creatures, powerful relics and decisions that matter.
A Deck That Is Never the Same Twice
Every climb starts from scratch. After each victory you choose from a spread of new cards, and with more than 350 cards in the pool the deck you finish with depends entirely on what the Spire offers and what you dare to take. Lean into poison, stack up an impenetrable wall of block, or build an engine that cycles half your deck in a single turn — the combinations reward players who spot synergies early, and a tight, disciplined deck will usually climb further than an overstuffed one.
Four Characters, Four Ways to Climb
- The Ironclad
- A hardened soldier whose cards trade health for raw strength. The Ironclad thrives on heavy, direct attacks and self-healing, which makes it the most forgiving way to learn the rhythm of the Spire's turn-based combat.
- The Silent
- A deadly huntress built around poison, daggers and discard tricks. The Silent wins by outlasting enemies rather than overpowering them, stacking damage over time while her shivs and blocks keep her standing.
- The Defect
- A rogue automaton that channels orbs of lightning, frost and darkness. Its decks revolve around powering and evoking those orbs at exactly the right moment, rewarding players who like to plan a turn or two ahead.
- The Watcher
- A blind ascetic who shifts between stances — calm to gather energy, wrath to double her damage. The Watcher is the most explosive of the four and punishes mistakes just as hard, which is precisely why veterans love her.
An Ever-Changing Spire
The tower is laid out differently on every run. You choose your own route through each act — a risky branch toward elites and treasure, or a quieter path past campfires and merchants — and you will meet different enemies, different events and even different bosses along the way. With more than 50 unique combat encounters and over 50 mysterious events that can help or harm you, no two climbs play out alike, and every decision about where to go next is part of the puzzle.
Relics and Powerful Interactions
Scattered through the Spire are more than 200 items to find, chief among them relics — passive effects that can reshape an entire run. Some turn an average deck into a machine; others come with strings attached, and a tempting relic may cost you more than just gold. Learning which relics pair with which cards is where the game's long tail of discovery lives, and where a single clever combination can carry you past a boss that had beaten you a dozen times before.
Built for the Long Climb
- Daily Climbs hand every player in the world the same seeded run and modifiers, so you can measure yourself against the community on equal terms and see exactly who reached the top.
- Custom mode lets you mix and match run modifiers for self-imposed challenges, while Steam Workshop support opens the door to a deep well of community-made characters, cards and rule tweaks.
- Thoughtful accessibility options — adjustable text size, custom volume controls, play without timed input and the ability to save at any point — make it easy to climb at your own pace, whether that is a quick run over lunch or a long evening session.
Pick your character, take your first card and find out how far this climb goes. The Spire will not be the same one anyone else faced, and that is exactly the point — your next run starts the moment you step through the door.
