Slay the Spire at a glance
Adapt the acclaimed roguelike video game into a cooperative deck-building campaign that can be played one act at a time or continued across multiple acts.
Why We Love It
Each character builds differently, and cooperative card timing creates tactical interactions that do not exist in the solo digital game.
About Slay the Spire: The Board Game
One to four players choose from Ironclad, Silent, Defect and Watcher, each with a distinct starting deck. The party follows a branching map through encounters, events, merchants and campfires, improves individual decks and faces a boss at the end of an Act.
This is a cooperative physical adaptation of the roguelike video game. A companion app exists but the printed rules say it is optional; the box can be played without a screen. An Act can stand alone, or the group can save after its boss and continue later.
How an Act and combat round work
Start with a character deck and choose a path on the Act map. Ordinary fights provide rewards; elites can offer stronger rewards at greater risk; events, merchants, treasure and campfires change the plan. At a campfire, each player chooses to heal or upgrade a card. At a merchant, gold can buy cards, relics and potions or remove a card, so the path itself becomes a deck-building decision.
Combat uses a shared Player Turn followed by an Enemy Turn. At the start of the Player Turn, each player resets Energy and Block, draws five cards and the group rolls one die for effects that require it. Players then coordinate card plays, potions and abilities; cards cost Energy. The enemies act in order after the group finishes. Some effects hit a chosen row, and enemy actions usually target the player in their row, so coordinate protection and damage rather than treating each character as a separate solo game.
If any player reaches zero HP, the party loses. Defeat an Act boss to win that Act; the group may stop there, save and continue later, or proceed immediately. The publisher’s rulebook estimates 60–90 minutes per Act and advises extra time for a first session; its product page instead lists roughly 45 minutes per player.
Key decisions and team strategy
Editorial analysis: Judge a new card by what the deck currently needs. An attractive attack can be worse than a way to block, draw or smooth Energy if the party already deals enough damage. Removing an underperforming starter card can make strong cards appear more often; upgrading at a campfire is worthwhile only if the team can afford to skip healing.
Route example: before taking an elite, look at current HP, relics and whether a campfire or merchant lies on the next path. The stronger reward may justify risk early in an Act, but a nearly defeated character can make one aggressive detour cost the whole run.
Combat example: announce Weak, Vulnerable and incoming attacks before spending Energy. One character may be able to finish a dangerous enemy while another blocks a row that would otherwise be hit. The relevant question is which threats survive the next Enemy Turn, not which player deals the most damage.
Who it suits and what the box requires
Choose it if your group wants a cooperative deck-building campaign with tactical table talk and a clear stopping point after an Act. Solo play is supported. The four characters reward repeat play, but there is substantial card and enemy upkeep compared with the video game. The app is an optional rules and tracking aid, unlike the required app in Mansions of Madness Second Edition.
First-game character choice
The rulebook points new players toward Ironclad and Silent; Defect is harder and Watcher the most demanding to learn. Start with an Act I run and decide whether to continue after the boss. No separate expansion is needed for this progression.
Common questions
Can we stop after one Act?
Yes. The rulebook treats defeating the chosen final boss as victory and explicitly allows stopping or saving after an Act.
Is the companion app required?
No. The printed rulebook calls it optional; it offers searchable rules and extras.
Does one player dying end the run?
Yes. A character reaching zero HP ends the party’s attempt in defeat.
