How to play Blades in the Dark
2–5 players · 180 min
Blades in the Dark is a tabletop RPG designed by John Harper and published by Evil Hat Productions in 2017. Set in a ghost-haunted industrial city called Doskvol — think Victorian London crossed with a dark fantasy Venice — it puts players in the role of a crew of scoundrels pulling off heists, cons, and criminal operations against rival gangs, corrupt noble houses, and the city's brutal Bluecoat enforcers. Blades pioneered several influential mechanics: the Score (mission-based structure), the Flashback system (improvise your preparation retroactively), Clocks (visual timers representing competing threats), and the downtime economy between scores. It has become one of the most studied and emulated RPG designs of the past decade and spawned an entire family of "Forged in the Dark" games across different genres.
How to play
The crew and playbooks: Players collectively choose a Crew Type (Assassins, Bravos, Cult, Hawkers, Shadows, Smugglers) that defines their home turf, starting contacts, and available upgrade paths. Each player then chooses a Character Playbook (Cutter, Hound, Leech, Lurk, Slide, Spider, Whisper) representing their specialty. Playbooks provide starting actions, special abilities, and advancement options. Action ratings and rolls: Each character has 12 Actions grouped into three attributes: Insight (Hunt, Study, Survey, Tinker), Prowess (Finesse, Prowl, Skirmish, Wreck), and Resolve (Attune, Command, Consort, Sway). Roll a pool of d6s equal to your action rating (0–4); 6 = full success, 4–5 = success with consequence, 1–3 = failure with worse consequence. Two or more 6s = critical success. The GM (Game Master, called the Blades GM or "the Referee") sets Position (how much danger you're in: Controlled, Risky, Desperate) and Effect (how impactful a success will be: Limited, Standard, Great) before each roll. Trading Position for Effect or vice versa is a negotiation between player and GM. The Score: Each session typically centers on a Score — a job the crew has contracted to do. Rather than planning extensively upfront, the Score begins in media res (already in action). When players need to have prepared something ("I would have scouted the building beforehand"), they call for a Flashback — a brief scene narrating that preparation, rolled for if difficult. Clocks: Circular tracks of 4, 6, 8, or 12 segments used to track progress on ongoing threats (enemy plans, crew goals, long-term projects). Filling a clock triggers its consequence or completion. Downtime: Between scores, crews recover stress, recover harm, engage in long-term projects, train, reduce heat (police attention), and indulge their vices (the primary stress relief mechanism). Coin earned during scores is converted to Rep and Coin for the crew's faction standing and upgrade purchasing.
Strategy
Blades in the Dark is designed for improvisational, fiction-first play — the system rewards players who commit boldly and accept consequences rather than trying to "solve" encounters safely. Embrace consequence-driven play: In most RPGs, failure is bad and avoided. In Blades, a 4–5 result (success with a complication) is expected and often dramatically interesting. The game's pacing depends on complications creating new problems to solve. Players who roll conservatively and retreat at complication signs miss the game's core pleasure — committing to a bold move and dealing with whatever follows. Position and Effect negotiation: Before rolling, always know your Position and Effect. A Desperate position might still be worth it for Great Effect; a Controlled position with Limited Effect might suggest a different approach entirely. Changing position by establishing fictional advantages (getting high ground, having a contact in the building) before rolling is a key skill. Stress as a resource: Characters have a Stress track (9 points) and can spend stress to push themselves (add an extra die) or resist consequences (reduce the severity of a result). Stress is not just a buffer — it is an action economy tool. Burning stress to add dice on critical rolls is correct play, not desperation. Vice indulgence during downtime is the recovery mechanic. The Flashback is your planning tool: Never spend 30 minutes planning a heist at the table. Instead, begin the score immediately and use Flashbacks when preparation would logically have happened. "I flash back to bribing the guard yesterday" — roll Consort and narrate. Flashbacks are retroactive improvisation and are one of Blades' most distinctive features. Crew advancement: Between scores, the crew spends Rep to advance their crew tier (their status in the criminal underworld) and Coin to buy upgrades (better equipment, training options, special abilities). Tier advancement is the long-term progression arc — moving from Tier 0 scoundrels to feared Tier IV criminal masterminds.
Tips
- Don't plan the heist extensively upfront — use Flashbacks when you need something to have been prepared. - A 4–5 result is success with a complication, not failure — lean into complications as story fuel, not obstacles to avoid. - Spend stress freely to push yourself on critical rolls; your Vice indulgence during downtime restores it. - Know your Position before you roll — Desperate means bad things happen even on success, Controlled means you have room to fail. - Trauma (permanent consequences from filling your stress track) is character-defining, not the end of your character. - Heat (how much the authorities are looking for you) matters — balance ambitious scores with downtime to reduce heat before the law comes knocking. - Faction clocks (rival gangs, noble houses) advance between sessions whether you interact with them or not — engage with the city's political landscape, not just individual jobs. - Special abilities from your playbook are the most impactful choices you make; read all options before choosing.
Players and time
2–5 players (1 GM + 1–4 players) in about 180 minutes per session, often running as a campaign. A single "Score" is usually one session; campaign play develops crew reputation and character advancement over many sessions.
Forged in the Dark family
Blades' mechanics have been adapted into dozens of games: Scum and Villainy (space opera), Band of Blades (military fantasy), Beam Saber (mech pilots), Wildsea (post-apocalyptic sailing), and many more. Learning Blades makes these sister games immediately accessible.
Doskvol setting
The city of Doskvol is a rich sandbox of interlocking factions, criminal gangs, noble houses, and supernatural undercurrents. The setting's darkness (all light beyond the city's lightning barriers is dangerous ghost-haunted dark) is baked into its tone — crime fiction meets gothic horror.
Common GM mistake
Treating Blades like a traditional RPG by placing guards, planning encounters, and expecting players to solve them. Blades works when the GM creates consequences and advances clocks in response to player actions — not by blocking them with prepared obstacles.
