Gameplay overview

Deck-building roguelike

Slay the Web recreates the rhythm of Slay the Spire: navigate a branching map, take on battles, and gradually assemble a synergistic deck. Each fight reveals enemy intents, forcing you to balance damage and defence turn by turn. Between encounters you’ll draft cards, collect relics, and upgrade key abilities before facing elite foes and bosses.

Slay the Web quick reference
Learn the basic loop: plan your route, play cards efficiently, and prepare for the boss at the end of each act.

Controls & UI

Mouse-first interface

  • Click cards to queue them; press End Turn when finished.

  • Multiple hero classes with unique starter decks.
  • Events, merchants, and campfires where you can upgrade or heal.
  • Runs persist in your browser—return later to continue a climb.
  • Extendable codebase documented for modders and new card designers.
