Frequently Asked Questions about Deck Quest

What is Deck Quest?
Deck Quest is a free browser-based deck-building roguelike inspired by games like Slay the Spire. You build a deck of attack, defense, and skill cards while fighting through 3 acts of increasingly difficult enemies, with a boss at the end of each act.
How do I play Deck Quest?
Each turn you draw 5 cards and get 3 energy. Tap a card to play it: red attacks deal damage, blue skills give block and other effects, and green powers last the whole fight. The icon above each enemy shows exactly what it will do next, so you can block an attack before it lands. End your turn, the enemies act, and you draw a fresh hand.
What happens when I die?
Deck Quest is a roguelike, so a defeat ends that run. Every floor you reach earns renown, which unlocks new cards and relics for future runs, and winning a run unlocks Heat, a harder mode with extra rules.
What are relics in Deck Quest?
Relics are powerful passive items you can find by defeating elite enemies, bosses, or purchasing from shops. They provide permanent bonuses for your run like extra energy, starting block, healing after combat, or bonus damage. You keep all relics until the run ends.
How long does a full run take?
A complete run through all 3 acts takes about 5 to 10 minutes. Each act has 6 floors: fights, elites, shops and events, then a campfire and a boss. An unfinished run is saved, so you can come back to it.
Is Deck Quest free to play?
Yes! Deck Quest is completely free to play in your browser on PlayBrain. No downloads, no sign-ups, and no paywalls. Your progress saves automatically to your browser.

About Deck Quest

Deck-building games combine card game strategy with roguelike progression. Pioneered by the tabletop game Dominion in 2008 and popularized digitally by Slay the Spire in 2019, the genre tasks players with constructing a powerful deck from a starting hand of weak cards. Each run is unique based on which cards you draft, which relics you find, and which enemies you face, creating enormous replayability and deep strategic decision-making. PlayBrain's Deck Quest distills this formula into a fast browser experience with three acts of escalating difficulty, over a dozen relics, 23 enemies, and boss fights that test every choice you made along the way.

How to Play

  1. Start with a basic deck of cards. Play red cards to attack enemies, blue cards to defend yourself, and green cards for special effects.
  2. Add new cards to your deck after each battle. Build powerful combos and synergies by choosing cards that work together.
  3. Manage your energy each turn. Every card costs energy to play, so prioritize the most impactful cards.
  4. Defeat the boss at the end of each act to advance. Survive all three acts to win the run.
