Slay the Spire challenges you to ascend a mysterious tower while strategically battling foes using a dynamic deck of cards. Your journey unfolds across three acts, each ending with a tough boss fight. With a procedurally-generated map, no two climbs will ever feel the same, making each playthrough an exciting new venture.

Choose between distinctive characters, starting with the resilient Ironclad, and unlock others like the tactician Silent or the versatile Defect after completing specific runs. Each character brings their own unique style and deck of cards to the table, encouraging you to experiment with various strategies.

The heart of the game lies in your deck management. Carefully select and combine cards while collecting powerful relics that can transform your strategy. Watch out for unpredictable enemies and random events that can drastically change your fate. With daily challenges, you can even test your skills against others, adding a competitive edge to your climbs.
